Introduction

This repository is part of the Magento DevBox project. The goal of this project is to minimize the effort to set up a local development machine (e.g. a laptop) for development of Magento 2 projects.

This project uses Docker, a containerization technology similar to Virtual Machines. This allows developers to work on multiple projects concurrently, which may need different versions of tools, without the pain of having to install all those versions natively.

The environment is designed for development of Magento 2 projects - the environment provided is not for production usage.

Please note, a previous version of DevBox included a web site with GUI to preconfigure your installation. While useful to get going, developers still needed to understand the underlying commands. The new DevBox has less 'magic', resulting in these instructions being longer, but developers having more control.

General Operation

DevBox contains all the the software packages you need to develop a Magento site, except for IDEs and web browsers. A local development environment typically starts with a database container (holding MySQL) and a web server container (holding the Magento source code). On Mac and Windows, another container is used for file sharing (discussed below). Other containers can be added as required for Varnish (recommended), Redis, RabbitMQ, and ElasticSearch. All containers run Linux inside.

Developers mainly interact with the web container. The other containers are relatively shrink wrap. For example, some commands must be run by using ssh to log into the web container.

Normally you set up containers and use them for a long time, removing them only when no longer required. Containers can be 'stopped' without being 'removed' to save CPU and memory resources while not in use. This is particularly useful when you are working on multiple projects.

Installation

This section walks you through how to install DevBox.

0. Prerequisites

• Install a recent version of Docker from http://docker.com/. Docker is available for Windows, Mac, and Linux.
• On Windows 10, as part of the Docker installation process you may need to turn on Hyper-V and then grant Docker access to the C: drive for Docker to mount volumes correctly. This is described in the Docker documentation.
• On Windows, it is recommended to install "Git Bash" (https://git-for-windows.github.io/). This includes the git client, an ssh client, an xterm terminal emulator, and a useful collection of commonly used Linux commands. The following instructions assume you are using Git Bash.
• On Mac, install "Brew" (https://brew.sh/) if you have not done so already.

1. Create a Local Project Directory

Create a new directory per project. Use a short but meaningful directory name as it is also used as a prefix for DevBox containers.

Download an initial set of files to the project directory.

• Go to https://github.com/alankent/magento2devbox-skeleton
• In the "Branch" drop down, select the tag closest to the project's version of Magento. This is to get the correct version of PHP, MySQL, etc. [Note: this is a work in progress. Currently only "master" is avaialble.]
• Click on the green button "Clone or Download" and select "Download ZIP".
• Extract the ZIP file contents into the project directory.

It is common to modify these downloaded files and delete unwanted files. For example, on Mac feel free to delete any Windows BAT files.

2. Review and Update the docker-compose.yml File

The following steps set up the Docker configuration files before the containers can be started.

Review the docker-compose.yml file in a text editor, making necessary adjustments as described by comments in the file. This includes:

• Mac and Windows uses a utility called Unison to bi-directionally synchronize files between the Docker containers and the local file system. Unison is similar in concept to rsync, but more fully featured. To enable Unison, make sure the /var/www volume is uncommented and the ./shared/www:/var/www line is commented out (or deleted). Make sure the "unison" service is also uncommented.

• For Linux, direct file sharing can be used if preferred. Make sure the ./shared/www:/var/www line is uncommented and the /var/www line is commented out. Also comment out the "unison" service as it is not required. Direct file sharing is not recommended for Mac or Windows for performance reasons.

• Check the port numbers. By default Docker will allocate random free port numbers. Change ports such as "80" to "8080:80" if you want the web server port to be always 8080. You cannot run different containers at the same time using the same port numbers. On Mac, there is a default web server running on port 80 so you must use a different port number for the web server container.

• The recommended way to create and update projects is via Composer, a PHP package manager. Magento provides a Composer repository from which Magento (and extensions purchased from Magento Marketplace) can be downloaded. Composer caches downloads for performance. Mounting the cache directory on your laptop is enabled by uncommenting the "~/.composer" volume mount in the docker-compose.yml file. This allows downloads to be shared between containers (e.g. on different projects). If you do not mount a directory, the cache will discarded when the container is removed.

• Add your Magento Marketplace download access keys as web service environment variables if you want to share these keys easily with other developers on the same project. (You can share the docker-compose.yml to ensure a consistent setup between team members.) Otherwise Composer will prompt you for the keys later. Keys are available from https://marketplace.magento.com/. (Go to "My Profile", "My Purchases", "Access Keys".)

• If you plan to use Varnish during development, uncomment the appropriate lines to create the Varnish container. A common source of production defects is the lack of testing with Varnish during development. As such, some developers prefer to develop with Varnishing caching turned on to spot problems early.

• Similarly, if you plan to use Redis, ElasticSearch, or RabbitMQ in production, uncomment the appropriate lines so you can test during developement.

3. Launch the Containers

Launch the containers by changing to the project directory and then running:

docker-compose up -d

You can check what containers exist using

docker ps -a

To log into the web container, use the provided m2ssh BAT and bash scripts. These automatically pick up the SSH port number from the docker-compose.yml file and logs on to the 'magento2' account of the 'web' container.

./m2ssh

If you are running Docker in VirtualBox, you may need to edit the provided scripts to replace "localhost" with the IP address allocated by VirtualBox.

Note: If you destroy and recreate containers, SSH may report warnings about changes in identity and refuse to connect. Use a text editor to remove "localhost" lines from your ~/.ssh/known_hosts file to overcome this issue (you will then be prompted to accept new fingerprints on restart).

4. Start Unison (Mac, Windows)

If you are using Unison for file syncing the host and web container file system (recommended on Mac and Windows), you also need to start up a Unison process (and keep it running).

Each time you log to your laptop, make sure you restart Unison, but be careful to not have multiple copies running in parallel. It is not recommended to do significant work on the project without Unison running to avoid merge conflicts (rare).

Mac

On Mac, first install Unison using "brew". This installs the correct command line version of Unison. Also install "unox" for a companion file watching utility.

brew install unison
brew tap eugenmayer/dockersync
brew install eugenmayer/dockersync/unox

Use the provided shell script to start up Unison. This shell script creates a Unison "profile" file in ~/.unison/m2devbox-{myproj}.prf ({myproj} is the current directory name) then starts up Unison in file watching mode.

./m2unison.sh

It is recommended to run Unison in a separate Terminal window so you can refer to its output if you ever need to do troubleshooting. This is also useful when synchronizing a large number of files for the first time to know when the copy has completed.

If you ever restart the Docker containers, you may need to rerun m2unison.sh to pick up any port number changes.

Windows

On Windows, run the supplied BAT file to launch Unison in a separate window using the START command or by double clicking the BAT file via Windows file explorer. This will automatically retrieve a copy of the unison.exe binary from the web container. A profile is not required as the BAT file uses command line arguments. Close the window to kill Unison.

START m2unison.bat

Note: The shell script (m2unison.sh) is not intended for use on Windows.

5. Install Magento

Next you need to install your Magento project inside the web container under the /var/www/magento2 directory. (Apache is configured by default to use /var/www/magento2 as the document root.) There are multiple options here.

Note: The first time you run Composer in the following steps, it may prompt you for a username and password. Enter your 'public' and 'private' keys from http://marketplace.magento.com/, "My Profile", "Access keys" when prompoted. Be aware that an auth.json file holding your keys will be saved into ~/.composer/. If you want to share the Composer downloaded files but have a different auth.json file per project, move the auth.json file into your project's home directory (/var/www/magento2). Most people add the auth.json file to their .gitignore file to avoid accental sharing of the keys.

Option 1: Existing Project

If you have an existing set of project files, place them under the shared/www/magento2 directory on your laptop. If you use volume mounting, the code will automatically be visible; if you use Unison, Unison will copy files on your laptop into the web container when it is running. Also please note if using Unison, symbolic links will not be copied into the container.

Option 2: Creating a New Project with Composer

Log into the web container.

./m2ssh

Create a new project under /var/www/magento2 using the Composer "create-project" command. Update the project edition and version number as appropriate. This example uses Magento Open Source (formerly "Community Edition") version 2.2.0.

cd /var/www/magento2
composer create-project --repository=https://repo.magento.com/ magento/project-community-edition:2.2.0 .
chmod +x bin/magento

Option 3: Getting Code from a GitHub Project

It is strongly recommended to save your project code in a private git repository on a hosting provider such as GitHub or BitBucket. The following describes how a new environment can get the code from such an environment.

The first step is to decide whether you plan to run normally git on your laptop or inside the container. Running it on the laptop is more frequent as many IDEs have integrated git support

On your laptop, check out the project into the magento2 directory.

cd shared/www
rm -rf magento2
git clone https://github.com/mycompany/myproject.git magento2

Log into the web container:

./m2ssh

Use Composer to download all the additional needed packages.

cd /var/www/magento2
composer install

Alternatively, you can check out the project from inside the container if you plan to run all your git commands there.

cd /var/www
rm -rf magento2
git clone https://github.com/mycompany/myproject.git magento2
cd magento2
composer install

Option 4: Magento Commerce (Cloud)

TODO: WARNING: THIS SECTION IS NOT COMPLETE.

The following discussion is not a replacement for reading through the Magento Commerce Cloud documentation on http://devdocs.magento.com/, but it summarizes the main steps most users would take.

1. Create your project using the Magento Cloud console.
2. Make sure you have SSH keys set up to access the account. (See magento-cloud ssh-keys and magento-cloud ssh-key:add.) The magento-cloud CLI is preinstalled in the web service container.
3. In the Magento Cloud console, click on "GIT" next to the "CLI" button to show the git command to check out the project's source code.
4. Remove the default magento2 directory.
5. Check out the cloud git repo under the magento2 directory. MAKE SURE YOU CHANGE THE LAST GIT ARGUMENT TO magento2.
6. Run composer install to download all other dependencies.
7. If you have any cloud patches you wish to use during development, run the patch.php file from the cloud configuration package.

The following is a sample session

cd /var/www
rm -rf magento2
git clone --branch master [email protected]:12myproj34.git magento2
cd magento2
xdebug-off
composer install
php vendor/magento/magento-cloud-configuration/patch.php
chmod +x bin/magento

Note that magento-cloud get is an alternative to the git clone command above, but it is recommended to use git directly to check the code out into the correct directory name (/var/www/magento2) as required by DevBox.

Option 5: Internal Development

TODO: THIS SECTION IS INDICATIVE OF FUTURE DIRECTION, NOT SUPPORTED YET.

This section is only relevant to internal Magento developers, or external developers wishing to submit a pull request. The following is not recommended for production sites. (It may however be worth exploring by extension developers.)

Log into the web container:

./m2ssh

Make a local clone of Magento Open Source (formerly Community Edition). Use your own fork repository URL if appropriate.

cd /var/www
rm -rf magento2
git clone https://github.com/magento/magento2skeleton.git magento2

git clone https://github.com/magento/magento2ce.git
git clone https://github.com/magento/magento2ee.git
git clone https://github.com/magento/magento2b2b.git

cd magento2
composer config repositories.ce path "../magento2ce/app/*/*/*"
composer config repositories.ee path "../magento2ee/app/*/*/*"
composer config repositories.b2b path "../magento2b2b/app/*/*/*"

composer install

Option 6: Recreating Docker Containers

If you decide to remove and re-create the Docker containers, the existing code will remain under shared/www/magento2 on your laptop. These files will be automatically picked up when the new set of containers are launched.

If using Unison, symbolic links are not copied. You may need to run composer install inside the web container to recreate any symbolic links required by Composer.

6. Create the Database

Magento DevBox runs MySQL in a separate database container. The MySQL container by default does not have a database created for Magento to use. The following creates the database magento2.

Log on to the bash prompt inside the web container

./m2ssh

Run the following commands to create a MyQL database for the web site to use (plus a second database for integration tests to use).

mysql -e 'CREATE DATABASE IF NOT EXISTS magento2;'
mysql -e 'CREATE DATABASE IF NOT EXISTS magento_integration_tests;'

After the database is created, uncomment the line setting the default database in the MySQL ~/.my.cnf file.

sed -e 's/#database/database/' -i ~/.my.cnf

The mysql command can now be used without arguments or selecting database.

mysql
> SHOW TABLES;
> exit;

Set up all the Magento 2 tables with the following command (adjusting command line parameter values as desired). (See below for extra arguments if you wish to use RabbitMQ as well.)

magento setup:install --db-host=db --db-name=magento2 --db-user=root --db-password=root --admin-firstname=Magento --admin-lastname=Administrator [email protected] --admin-user=admin --admin-password=admin123 --language=en_US --currency=USD --timezone=America/Chicago --use-rewrites=1 --backend-frontname=admin

It is recommended to NOT include the --base_url option during development as Docker can allocate a port number at random (including when container is restarted). It also causes problems using BrowserSync and similar tools for frontend development. Some versions of Magento however have a bug requiring --base_url to be specified. If the URL to CSS files is incorrect, you may have a broken version of Magento. If this is the case, force the web server port number be a specific port (e.g. use "8080:80" in docker-composer.yml) and add the --base_url command line option (e.g. --base_url=localhost:8080).

TODO: I THINK YOU CAN RUN A SEPARATE COMMAND LATER. IF CORRECT, MOVE THIS TO A SEPARATE SECTION. If you are using RabbitMQ (AMPQ), the following command line arguments should be added when the project was created above.

--amqp-virtualhost=/ --ampq-host=ampq --amqp-port=TODO --amqp-user=guest --amqp-password=guest

7. Loading Sample Data (Optional)

To download the Luma sample data, you may need to provide Composer authentication details. If you already have a ~/.composer/auth.json file you can run

COMPOSER_AUTH=$(cat ~/.composer/auth.json) magento sampledata:deploy

If you don't have a ~/.composer/auth.json file, just run magento sampledata:deploy and enter your public and private keys when prompted.

To load the downloaded sample data into the database, run

magento setup:upgrade

8. Cron (Optional)

Cron is disabled by default as running cron may result in faster draining of laptop batteries. To manually trigger background index updates, run magento cron:run twice in a row (sometimes the first cron schedules jobs for the second cron to run).

cd /var/www/magento2
magento cron:run
magento cron:run

To enable cron permanently (recommended) run the following command.

cron-install

9. Put Site into Developer Mode

Magento supports developer and production modes. Production mode makes optimizations assuming files on the site will not change. Developer mode is suitable when making changes to a site during development.

magento deploy:mode:set developer

10. Connect with a Web Browser

You are now ready to connect to your installation with a web browser.

If you did not specify a fixed port number in the docker-composer.yml file for your site, run the following command to determine the web server port number that was allocated to the web service container. (This is normally different to the port number used inside the container.)

docker-compose port web 80

If the response is, for example, port 8080, connect to the web server store front using

http://localhost:8080/

Connect to the Magento Admin by appending /admin with username "admin" and password "admin123" (from the earlier magento setup:install command)

http://localhost:8080/admin

If you are running Docker inside VirtualBox, replace "localhost" with the IP address VirtalBox allocated to the VM Docker is running within.

Be aware that in developer mode the slower PHP debug mode is on and missing CSS and similar files are created on demand. This means the first time you load a page you will see significantly longer load times. The more pages you access, the faster the site will become.

11. Configure PHP Storm (Optional)

TODO: WARNING: THIS SECTION IS NOT COMPLETE.

PHP Storm is a popular IDE for PHP development. This section describes common PHP Storm configuration settings for Magento 2 projects. PHP Storm has changed (and will continue to change) over time, so the following instructions are indicative only.

The following instructions assume the previous steps have already been completed.

Create New Project

1. Create a new project in PHP Storm using "Create New Project from Existing Files".
2. Use the option "Source files are in local directory, no Web server is yet configured." (We will add the web server by hand later.)
3. Select shared/www as the project root directory.
4. Go to "File" / "Settings" to bring up the project's "Settings" diaglog box.
5. Select "Directories" in the Settings Diaglog side bar. Suggested settings are:
   • Mark the root directory as "Sources".
   • Mark magento2/dev/tests as "Tests".
   • Mark magento2/dev/tests/integration/tmp as "Excluded".
   • Mark magento2/pub/static as "Excluded". (This directory may not exist until you access the site, triggering its creation.)
   • Mark magento2/var as "Excluded".
   • Mark magento2/vendor/magento/magento2-base as "Excluded".
6. Select "Editor" / "File Encodings" in the Settings Diaglog side bar.
   • Set "Project Encoding" to "UTF-8".
7. Select "Languages & Frameworks" / "PHP" in the Settings Diaglog side bar.
   • Select "7" from the drop down list of PHP versions.
   • Click "..." next to "CLI Interpreter" to bring up a list of "CLI Interpreters".
   • Click "+" then "From Docker, Vagrant, VM, Remote".
   • Select "SSH Credentials". (You may try "Docker Composer" if you prefer, but it is more complicated to set up.) Use:
   • Enter localhost for the host name (or the IP address allocated by VirtualBox if running Docker inside VirtualBox).
   • Enter the port number from docker-compose port web 22 (e.g. 2222) for the port number.
   • Enter magento2 for the user name.
   • Select "Password" as the "Auth type".
   • Leave the password field blank.
   • Set the PHP executable path to /usr/local/bin/php.
8. Select "Tools" / "SSH Terminal", and select the "Default Remote Interpreter" radio button.

12. Varnish Configuration (Optional)

TODO: WARNING: THIS SECTION IS NOT COMPLETE.

Varnish is a "HTTP accelerator" that sits in front the web server and caches content of HTTP responses. It is recommended to use Varnish during development to help identify caching issues as early as possible.

To enable Varnish, run the following command. This updates configuration settings in the database.

varnish-install
# magento config:set --scope=default --scope-code=0 system/full_page_cache/caching_application 2

To connect via your web browser to Varnish, you must use the Varnish port number instead of the web server port number. To determine the Varnish port number, use

docker-compose port varnish 6081

13. Redis Configuration (Optional)

Uncomment the Redis service in the docker-compose.yml if you wish to use Redis during development, keeping your local development environment closer to your production setup. Redis is recommended if you have a cluster of web servers in production as an efficient way to share state (such as current session information) between them.

The Magento DevDocs site (http://devdocs.magento.com/) describes how to configuration Redis. The following instructions summarize the steps for Magento 2.2 onwards.

To turn on usage of Redis for session caching, run

cd /var/www/magento2
rm var/session/*
magento setup:config:set --session-save=redis --session-save-redis-host=redis --session-save-redis-log-level=3 --session-save-redis-timeout=10

To turn on usage of Redis for default data caching, run

magento setup:config:set --cache-backend=redis --cache-backend-redis-server=redis --cache-backend-redis-db=1

To turn on usage of Redis for page caching (not needed if using Varnish), run

magento setup:config:set --page-cache=redis --page-cache-redis-server=redis --page-cache-redis-db=2

14. ElasticSearch Configuration (Optional)

TODO

15. RabbitMQ Configuration (Optional)

TODO

16. Grunt and Gulp Configuration (Optional)

Grunt and Gulp are both frontend tool chains to speed up frontend development. They can both auto-recompile CSS files as soon as a file is written to disk. NodeJS is preinstalled in the web service container for use by Grunt and Gulp, along with grunt-cli, gulp-cli, and browsersync.

To enable Grunt support, run the following commands

cd /var/www/magento2
cp Gruntfile.js.sample Gruntfile.js
cp package.json.sample package.json
npm install
grunt refresh --force
grunt watch

For further details, please refer to the Grunt section in the "Frontend Developer Guide" on http://devdocs.magento.com/.

Magento does not ship with Gulp support, but there are numerous articles on the web explaining how to use Gulp with Magento 2, such as https://alankent.me/2016/01/27/gulp-et-al-in-magento-2/.

If you wish to run BrowserSync (https://www.browsersync.io/), with Gulp you need to ensure the BrowserSync ports (3000 and 3001) are left uncommented in the docker-compose.yml file.

Appendix 1: Developing Your Own Module or Extension

This section contains suggested ways in which you can manage modules or extensions that are being developed in a separate git repository to your main project. For example, a system integrator may wish to share a set of locally developed modules across multiple customers.

Single Module Projects

Composer has special support when there is one module per git repository. Composer can perform a git clone of the code automatically, where the code ends up under the vendor directory, like other downloaded modules, but you can edit and change the source code and commit your changes afterwards.

In this mode, you create your module in git first, then run the following commands to update the composer.json file.

First add a repository entry for the git repository, replacing "myvendor" and "mymodule" with your vendor and module name.

composer config repositories.mymodule vcs [email protected]:myvendor/module-mymodule.git

Next, add the dependency on your module. A version number with the form of "dev-{branch}" checks out that branch from the git repository.

composer require --prefer-source myvendor/module-mymodule:dev-master

Refer to the Composer documentation for more details and variations supported.

Multi-Module Projects

If you want to keep multiple modules in one git repo (so they version together), a different approach is required. Note this can also be used for git repositories containing a single module if desired.

First, check out your git repository under /var/www (alongside the magento2 directory).

cd /var/www
git clone [email protected]:myvendor/myrepo.git

Next, add a repository reference to all the directories containing packages (that is, all directories containing a composer.json file). You may use * in path wildcards to include multiple directories at a time. Make sure you use quotes to make sure the shell does not expand the wildcards. (The wildcard will match directories such as modules in app/code/Magento/* and themes in app/design/MyVendor/*.)

composer config repositories.myrepo path "../myrepo/app/*/*/*"

If developing a module, set the minimum stability to dev (and set it back to a stable level when going live). See the Composer documentation for more options.

composer config minimum-stability dev

You can then add dependencies to any of the packages in the specified directories. Composer will create a symlink from under the vendor/myvendor directory to the appropriate git repository directory.

composer require "myvendor/module-mymodule:*"

Note that while Unison will not sync the symlink, if you specify the shared/www local directory as the "source code root" in PHP Storm, it will find the PHP code under both /var/www/magento2 and /var/www/myrepo.

Appendix 2: Tips and Tricks

The following can be useful tips and tricks.

Other Docker Commands

To see what containers are running, use

docker ps -a

To stop the containers when not in use, use

docker-compose stop

If you are using Unison, it is generally recommended to exit it as well.

Restart the containers later with

docker-compose start

If you are using Unison, remember to also restart Unison for file syncing to work.

To get a bash prompt inside a container, use

docker-compose exec --user magento2 web bash

If you are using a Git Bash window on Windows, you may see an error message saying you need to use winpty. In that case you must use the following command.

winpty docker-compose exec --user magento2 web bash

This example specified the 'web' service container (see docker-compose.yml for the other service names).

In general this works well, but on Windows the 'exec' command will exit if you press CTRL+Z. If you like using CTRL+Z in Linux, this is rather annoying, so SSH access is recommended instead when logging into the web container. (SSH is not enabled on the other containers.)

Removing and Rebuilding Containers

When you no longer need the DevBox, you can kill and remove all of the running containers. THIS WILL WIPE ALL FILES INSIDE THE WEB CONTAINER AND THE DATABASE, LOSING ANY CHANGES FOREVER. It will not remove any locally synchronized files under the shared directory.

docker-compose kill
docker-compose rm

If you decide to change the settings in docker-composer.yml after the containers have been created, you will need to rebuild the containers. MAKE SURE THE SOURCE CODE IS UP TO DATE UNDER THE shared/www DIRECTORY ON YOUR LAPTOP BEFORE REBUILDING THE CONTAINERS TO MAKE SURE YOU DO NOT ACCIDENTALLY LOSE ANY OF YOUR WORK.

There are two strategies you can use. The first is to delete all the containers as above and then recreate them. This will delete the database contents as well.

docker-compose kill
docker-compose rm
# Make changes to docker-compose.yml
docker-compose up -d

If you are using Unison file syncing, when you restart Unison locally it will copy all the code from shared/www back into the /var/www directory inside the container. After that, magento setup:install can be run to rebuild the database.

The second approach is to use the --build option of Docker Compose which will only rebuild affected containers. For example, if opening up a new port to the web service container, using --build will not remove the database container, preserving its contents. When the /var/www directory is restored (via Unison or Volume mounting) the database connection settings (in env.php) will also be restored.

# Make changes to docker-compose.yml
docker-compose up -d --build

Note: If using Unison for file syncing, you may need to rerun composer install on your installation to recreate some symbolic links.

Kitematic

If you like GUIs, you may wish to install Kitematic from the Docker site as well. It provides a GUI to manage Docker containers. Kitematic does not understand Docker Compose, only individual containers.

You can use Docker command line commands in combination with Kitematic to manage containers, but sometimes Kitematic will not notice command line changes, requiring Kitematic to be exited and restarted to refresh the container list it is aware of.

Other Magento Commands

To flush various caches:

magento cache:flush

Tell any configured external caches (e.g. Redis) to clean themselves.

magento cache:clean

Run shell script to remove all generated files and clean all caches.

clean-generated

To run cron by hand if not running automatically (run this twice to gurantee all jobs are queued and run).

magento cron:run

To check module statuses

magento module:status

To disable/enable a module

magento module:disable Magento_Customer
magento module:enable Magento_Customer

To rebuild indexes

magento indexer:reindex

Appendix 3: File Syncing

The biggest issue with using Docker or other virtualization technologies is most developers (rightly) prefer using an IDE or text editor running natively (on the laptop). The challenge then is how to get the editor to be able to access the Magento source code where that code is also available to the web container.

Docker supports "volume mounting" which allows a Docker container to directly access the laptop file system. This works very well on Linux, but has performance issues on Mac and Windows when you have large numbers of files (such as with Magento).

Where volume mounts are not suitable (specifically, the Magento source code directory on Mac and Windows), DevBox syncs the local and container file systems using a program called Unison. Whenever a file in the watched local file system is changed, it is copied into the web container, and vice versa. This allows IDEs to be natively used on a laptop (or desktop) - Unison copies file changes as soon as they are written to disk into the web conatiner.

DevBox uses a similar approach to the "Docker Sync" project (http://docker-sync.io/) for file sharing, but only supports Unison.

Insiders secret: Unison is written in a language called OCaml. OCaml 4.01 and 4.02 changed a serialization algorithm in a backwards incompatible way. So you need to make sure you have Unison binaries on Windows, Mac, and Linux compiled with the same version of OCaml. Brew + Debian:Stretch + the supplied Windows binary currently all match. If you try experimenting with other binaries, beware the pit of despair when things start going strange for no apparent reason!

There are a number of implications from the above.

• Most developers prefer to use a IDE such as PHP Storm for development. PHP Storm has special support for "remote PHP interpeters" via ssh. This makes source code development and debugging using PHP Storm relatively painless even when PHP and the web server are running inside a Docker container. However, PHP Storm still needs access to the the source code for editing and debugging, which is why Unison is required.

• There are several directories (such as log directories) which you can choose to mount via Docker volumes for easy access directly from your laptop. These files are generally small in number and size for which Docker volume mounting works fine. By default the volume mounts are commented out in the docker-compose.yml file for improved performance.
