Installing in Docker

Installation

This guide will show you how to get akkoma working in a docker container, if you want isolation, or if you run a distribution not supported by the OTP releases.

If you want to migrate from or OTP to docker, check out the migration guide.

Prepare the system

• Install docker and docker compose
  • Docker
  • Docker-compose
  • This will usually just be a repository installation and a package manager invocation.
• Clone the akkoma repository
  • git clone https://akkoma.dev/AkkomaGang/akkoma.git -b stable
  • cd akkoma

Set up basic configuration

cp docker-resources/env.example .env
echo "DOCKER_USER=$(id -u):$(id -g)" >> .env

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.

./docker-resources/build.sh

This will generate a container called akkoma which we can use in our compose environment.

Generating your instance

mkdir pgdata
./docker-resources/manage.sh mix deps.get
./docker-resources/manage.sh mix compile
./docker-resources/manage.sh mix pleroma.instance gen

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.

Now we'll want to copy over the config it just created

cp config/generated_config.exs config/prod.secret.exs

Setting up the database

We need to run a few commands on the database container, this isn't too bad

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

./docker-resources/manage.sh mix ecto.migrate
# this will recompile your files at the same time, since we changed the config

Start the server

We're going to run it in the foreground on the first run, just to make sure everything start up.

docker compose up

If everything went well, you should be able to access your instance at http://localhost:4000

You can ctrl-c out of the docker compose now to shutdown the server.

Running in the background

docker compose up -d

Create your first user

If your instance is up and running, you can create your first user with administrative rights with the following task:

./docker-resources/manage.sh mix pleroma.user new MY_USERNAME MY_EMAIL@SOMEWHERE --admin

And follow the prompts

Reverse proxies

This is a tad more complex in docker than on the host itself. It

You've got two options.

Running caddy in a container

This is by far the easiest option. It'll handle HTTPS and all that for you.

mkdir caddy-data
mkdir caddy-config
cp docker-resources/Caddyfile.example docker-resources/Caddyfile

Then edit the TLD in your caddyfile to the domain you're serving on.

Uncomment the caddy section in the docker compose file, then run docker compose up -d again.

Running a reverse proxy on the host

If you want, you can also run the reverse proxy on the host. This is a bit more complex, but it's also more flexible.

Follow the guides for source install for your distribution of choice, or adapt as needed. Your standard setup can be found in the Debian Guide

You're done!

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

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