## Using docker-compose and the prebuilt-image (recommended)

This is the easiest method for running the bot without any modifications.  
**Do not clone the repository when using this method!**

1. Create a new directory and `cd` into it.

2. Create the `docker-compose.yml` file:

    ```yaml
    version: '3'
    services:
      qrm2:
        image: "classabbyamp/qrm2:latest"
        # OR
        # image: "docker.pkg.github.com/miaowware/qrm2/qrm2:latest"
        restart: on-failure
        volumes:
          - "./data:/app/data:rw"
        environment:
          - PYTHONUNBUFFERED=1
    ```
   > Note that there are two possible sources for the image: docker's and github's registry. Github's registry requires [a few extra steps](https://docs.github.com/en/packages/using-github-packages-with-your-projects-ecosystem/configuring-docker-for-use-with-github-packages) during the initial setup.

3. Create a subdirectory named `data`.

4. Copy the templates for `options.py` and `keys.py` to `data/`, and edit them.

5. Run `docker-compose`:

    ```none
    $ docker-compose pull
    $ docker-compose up -d
    ```

    > Run without "-d" to test the bot. (run in foreground)



## Using docker-compose and building the image

This is the easiest method to run the bot with modifications.

1. `cd` into the repository.

2. Create the `docker-compose.yml` file:

    ```yaml
    version: '3'
    services:
      qrm2:
        build: .
        image: "qrm2:local-latest"
        restart: on-failure
        volumes:
          - "./data:/app/data:rw"
        environment:
          - PYTHONUNBUFFERED=1
    ```

3. Create a subdirectory named `data`.

4. Copy the templates for `options.py` and `keys.py` to `data/`, and edit them.

5. Run `docker-compose`:

    ```none
    $ docker-compose build --pull
    $ docker-compose up -d
    ```

    > Run without "-d" to test the bot. (run in foreground)



## Using pure docker

This methods is not very nice to use.  
*I just wanna run the darn thing, not do gymnastics!*


### [Optional] Building the image

1. `cd` into the repository.

2. Run docker build:

    ```none
    $ docker build -t qrm2:local-latest .
    ```


### Creating the container

1. Be in a directory with a `data/` subdirectory, which should contain valid `options.py` and `keys.py` files (copy and edit the templates).

2. Run the container:

    ```none
    $ docker run -d --rm --mount type=bind,src=$(pwd)/data,dst=/app/data --name qrm2 [image]
    ```

    Where `[image]` is either of:
    - `discord-qrm2:local-latest` if you are building your own.
    - `classabbyamp/discord-qrm2:latest` if you want to use the prebuilt image.
