Docker Setup for Lucas Cranach Archive

Running the build

Create a copy of the file example-env and rename it to .env.

Set up the variables in the .env File.

The application runs with Docker Compose and contains two Container.

• cranach-elk ELK Stack that povides the data
• cranach-api Node JS application that provides the API

Build the images and run the containers

docker-compose build

Run the containers

docker-compose up -d

For debugging run the containers without detached mode

docker-compose up

Stop the containers

docker-compose stop

Start and Stop the containers on a remote server

To start and stop the containers on a remote server, you can use the following commands:

Login to the remote server

ssh -l <username> mivs02.gm.fh-koeln.de

Navigate to the directory where the docker-compose.yml file is located

cd /var/lucascranach/cranach-docker/

Start the containers

docker-compose -f docker-compose.yml -f docker-compose.prod.yml up -d

Stop the containers

docker-compose stop

Remote server

There are two remote servers for the Cranach API which can be accessed via the following URLs:

• https://mivs.02.gm.fh-koeln.de - Productive environment
• https://mivs.03.gm.fh-koeln.de - Development enviroment

The Deployment to the servers is handled via GitHub Actions and is triggered when changes are pushed to one of the following repositories: cranach-docker, cranach-api, cranach-elk On which server will be deployed depends on the branch to which changes are pushed or a pull request is merged. The following dependencies exist:

• mivs.02.gm.fh-koeln.de - master branches
• mivs.03.gm.fh-koeln.de - integration branches

Importing data to Elasticsearch

The importer is located in the directory importer.

If the data on the remote server is to be updated

• Push the zipped files to be imported on the server
  scp files.zip <username>@mivs02.gm.fh-koeln.de:~
• Log in to the server. ssh -l <username> mivs02.gm.fh-koeln.de
• Move the zip file to the files directory
  sudo mv files.zip /var/lucascranach/cranach-docker/importer/files/
• unzip and delete files.zip
sudo cd /var/lucascranach/cranach-docker/importer && unzip files.zip && rm files.zip
• Start the import script cd /var/lucascranach/cranach-docker/importer && make importesindices

If the data on the local machine is to be updated

• Put the files to be imported into the files folder.
• Make a copy of the file example-config.cfg and rename it to config.cfg.
• Now adjust the variable elasticsearch_indices_import_files in the file config.cfg.
• Start the import script: make importesinidices
