Requirements

• Python - 3.10+
• NodeJS - 12.20+

Setup

1. Clone repo and switch to the repo folder:

   git clone --recurse-submodules https://github.com/OpenYiff/Kemono2.git kemono-2
   cd kemono-2

2. Set up configs:

   cp kitsune.py.example kitsune.py # archiver config
   cp .env.example .env # open .env and configure
   cp redis_map.py.example redis_map.py # open redis_map.py and configure
   cp flask.cfg.example flask.cfg # open flask.cfg and set 'SECRET_KEY' value

Develop

For now Docker is a primary way of working on the repo.

Installation

1. Create a virtual environment:

   pip install virtualenv # install the package if it's not installed
   virtualenv --upgrade-embed-wheels # makes it easier to manage python versions
   virtualenv --python 3.8 venv

2. Activate the virtual environment:

   source venv/bin/activate # venv\Scripts\activate on Windows

3. Install python packages:

   pip install --requirement requirements.txt

4. Install pre-commit hooks:

   pre-commit install --install-hooks

IDE-specific

VSCode

Copy .code-workspace file:

cp configs/workspace.code-workspace.example kemono-2.code-workspace

And install recommended extensions.

Docker

docker-compose --file docker-compose.dev.yml build
docker-compose --file docker-compose.dev.yml up

Open http://localhost:5000/ in the browser.

Database

1. Register an account.
2. Visit http://localhost:5000/development.
3. Click either seeded or random generation.
4. This will start a mock import process, which will also populate the database.

Files

TBD

Build

docker-compose build
docker-compose up --detach

Open http://localhost:8000/ in the browser.

Manual

TODO: write installation and setup instructions

This assumes you have Python 3.8+ Node 12+ installed and a running PostgreSQL server.

# make sure your database is initialized
# cd to kemono directory
pip install virtualenv
virtualenv venv
source venv/bin/activate # venv\Scripts\activate on Windows
pip install --requirement requirements.txt
cd client && npm install && npm run build && cd ..
cp .env.example .env # open .env and configure
cp flask.cfg.example flask.cfg # open flask.cfg and configure
set FLASK_APP=server.py
set FLASK_ENV=development
flask run

Frequently Asked Questions

My dump doesn't migrate.

Assuming the running setup:

1. Enter into database container:

   docker exec --interactive --tty kemono-db psql --username=nano kemonodb

2. Check the contents of the posts table:

   SELECT * FROM posts;

   Most likely it has 0 rows.
3. Move contents of booru_posts to posts:

   INSERT INTO posts SELECT * FROM booru_posts ON CONFLICT DO NOTHING;

4. Restart the archiver:

   docker restart kemono-archiver

   If you see a bunch of log entries from kemono-db, then it means archiver is doing the job.
5. In case the frontend still doesn't show the artists/posts, clear redis cache:

   docker exec kemono-redis redis-cli FLUSHALL

How do I git modules?

Assuming you haven't cloned the repo recursively for whatever reason:

1. Initiate the submodules

   git submodule init
   git submodule update --init --recursive

2. Switch to archiver folder and add your fork to the remotes list:

   cd archiver
   git remote add <remote_name> <your_fork_link>

3. Now you can interact with Kitsune repo the same way you do as if it was outside of project folder.

How do I import from db dump?

1. Retrieve a database dump.
2. Run this command in the folder of said dump:

   cat db-filename.dump | gunzip | docker exec --interactive kemono-db psql --username=nano kemonodb

3. Restart the archiver to trigger migrations:

   docker restart kemono-archiver

   If that didn't start the migrations, refer to FAQ section for manual instructions.

How do I put files into nginx container?

1. Retrieve the files in required folder structure.
2. Copy them into nginx image:

   docker cp ./ kemono-nginx:/storage

3. Add required permissions to that folder:

   docker exec kemono-nginx chown --recursive nginx /storage
