This probably won't need to be changed, it's only there to set basic environment
variables for the docker compose file.
### Building the container
The container provided is a thin wrapper around akkoma's dependencies,
it does not contain the code itself. This is to allow for easy updates
and debugging if required.
```bash
./docker-resources/build.sh
```
This will generate a container called `akkoma` which we can use
in our compose environment.
### Generating your instance
```bash
mkdir pgdata
./docker-resources/manage.sh mix deps.get
./docker-resources/manage.sh mix compile
./docker-resources/manage.sh mix pleroma.instance gen
./docker-resources/generate-instance.sh
```
This will ask you a few questions - the defaults are fine for most things,
the database hostname is `db`, the database password is `akkoma`
(not auto generated), and you will want to set the ip to `0.0.0.0`.

```
### Setting up the database
We need to run a few commands on the database container, this isn't too bad
```bash
docker compose run --rm --user akkoma -d db
# Note down the name it gives here, it will be something like akkoma_db_run
docker compose run --rm akkoma psql -h db -U akkoma -f config/setup_db.psql
docker stop akkoma_db_run # Replace with the name you noted down
```
Now we can actually run our migrations
```bash
./docker-resources/manage.sh mix ecto.migrate
# this will recompile your files at the same time, since we changed the config
```

### Applying Postgresql optimisations
Your postgresql server will behave better if you tune its settings to your machine.
There is a file at `docker-resources/docker-compose.pgsql-tuning.yml` which shows you how to apply settings, for example
those generated by [PgTune](https://pgtune.leopard.in.ua/)
You can merge this config into a `docker-compose.override.yml` file to apply them. Make sure that you generate your options
based on the shm_size you allocate!

All that's left is to set up your frontends.

The standard OTP commands will apply to you, just make sure you
prefix them with `./docker-resources/manage.sh`!

The equivalent docker command would be
```
./docker-resources/manage.sh user new myuser

### Migrating from the old docker install system
If you were running akkoma in docker before 2024.06, you will need to do a few little migration steps.
First off, we need to migrate our postgres installation to a newer version!
```bash
./docker-resources/migrate-postgresql-version.sh pgdata 14 16
```
This should be nice and quick.
After that you can just `docker compose pull` and all should be fine.
