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!

||||
|
||||
### You're done!

The standard OTP commands will apply to you, just make sure you

||||

||||
So, for example, if an OTP command would be
|
||||
|
||||
```
|
||||
./bin/pleroma_ctl user new myuser
|
||||
```
|
||||
|
||||
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.
