## Docker Environment

Location: `.env`

In the table below the container host refers to the IP address that the docker
container listens on, setting this to `127.0.0.1` for example will only expose
the configured port to localhost, whereas setting to `0.0.0.0` will expose the
port on all interfaces.

The container port refers to the external docker container port, used to access
services within the container. Changing this does not require any changes to
configuration within container. For example setting the `MONGO_PORT` to `21018`
will allow you to access the mongo service through that port, even though the
application within the container is listening on `21017`.

| Property | Description |
| --- | --- |
| `COMPOSE_PROJECT_NAME` | Should be a unique name for this installation, especially if you have multiple instances of Musare on the same machine. |
| `RESTART_POLICY` | Restart policy for docker containers, values can be found [here](https://docs.docker.com/config/containers/start-containers-automatically/). |
| `CONTAINER_MODE` | Should be either `prod` or `dev`.  |
| `DOCKER_COMMAND` | Should be either `docker` or `podman`.  |
| `BACKEND_HOST` | Backend container host. |
| `BACKEND_PORT` | Backend container port. |
| `FRONTEND_HOST` | Frontend container host. |
| `FRONTEND_PORT` | Frontend container port. |
| `FRONTEND_MODE` | Should be either `prod` or `dev`. |
| `MONGO_HOST` | Mongo container host. |
| `MONGO_PORT` | Mongo container port. |
| `MONGO_ROOT_PASSWORD` | Password of the root/admin user for MongoDB. |
| `MONGO_USER_USERNAME` | Application username for MongoDB. |
| `MONGO_USER_PASSWORD` | Application password for MongoDB. |
| `MONGO_DATA_LOCATION` | The location where MongoDB stores its data. Usually the `.db` folder inside the `Musare` folder. |
| `MONGO_VERSION` | The MongoDB version to use for scripts and docker-compose. Must be numerical. Currently supported MongoDB versions are 4.0+. Always backup before changing this value. |
| `REDIS_HOST` | Redis container host. |
| `REDIS_PORT` | Redis container port. |
| `REDIS_PASSWORD` | Redis password. |
| `REDIS_DATA_LOCATION` | The location where Redis stores its data. Usually the `.redis` folder inside the `Musare` folder. |
| `BACKUP_LOCATION` | Directory to store musare.sh backups. Defaults to `/backups` in script location. |
| `BACKUP_NAME` | Name of musare.sh backup files. Defaults to `musare-$(date +"%Y-%m-%d-%s").dump`. |

## Docker-compose override

You may want to override the docker-compose files in some specific cases.
For this, you can create a `docker-compose.override.yml` file.

### Run backend on its own domain

One example usecase for the override is to expose the backend port so you can
run it separately from the frontend. An example file for this is as follows:

```yml
services:
  backend:
    ports:
      - "${BACKEND_HOST}:${BACKEND_PORT}:8080"
```

This assumes that you have also set `BACKEND_PORT` inside your `.env` file.
