# Pleroma
[Pleroma](https://pleroma.social/) is a federated social networking platform, compatible with GNU social and other OStatus implementations. It is free software licensed under the AGPLv3.
It actually consists of two components: a backend, named simply Pleroma, and a user-facing frontend, named Pleroma-FE.
Its main advantages are its lightness and speed.

_Pleromians trying to understand the memes_
## Features
- Based on the elixir:alpine image
- Ran as an unprivileged user
- It works great
Sadly, this is not a reusable (e.g. I can't upload it to the Docker Hub), because for now Pleroma needs to compile the configuration. 😢
Thus you will need to build the image yourself, but I explain how to do it below.
## Build-time variables
- **`PLEROMA_VER`** : Pleroma version (latest commit of the [`develop` branch](https://git.pleroma.social/pleroma/pleroma) by default)
- **`GID`**: group id (default: `911`)
- **`UID`**: user id (default: `911`)
## Usage
### Installation
Create a folder for your Pleroma instance. Inside, you should have `Dockerfile` and `docker-compose.yml` from this repo.
Here is the `docker-compose.yml`. You should change the `POSTGRES_PASSWORD` variable.
```yaml
version: '2.3'
services:
postgres:
image: postgres:9.6-alpine
container_name: pleroma_postgres
restart: always
environment:
POSTGRES_USER: pleroma
POSTGRES_PASSWORD: pleroma
POSTGRES_DB: pleroma
volumes:
- ./postgres:/var/lib/postgresql/data
web:
build: .
image: pleroma
container_name: pleroma_web
restart: always
ports:
- '127.0.0.1:4000:4000'
volumes:
- ./uploads:/pleroma/uploads
depends_on:
- postgres
```
Create the upload and config folder and give write permissions for the uploads:
```sh
mkdir uploads config
chown -R 911:911 uploads
```
Pleroma needs the `citext` PostgreSQL extension, here is how to add it:
```sh
docker-compose up -d postgres
docker exec -i pleroma_postgres psql -U pleroma -c "CREATE EXTENSION IF NOT EXISTS citext;"
docker-compose down
```
Configure Pleroma. Copy the following to `config/secret.exs`:
```exs
use Mix.Config
config :pleroma, Pleroma.Web.Endpoint,
http: [ ip: {0, 0, 0, 0}, ],
url: [host: "pleroma.domain.tld", scheme: "https", port: 443],
secret_key_base: "<use 'openssl rand -base64 48' to generate a key>"
config :pleroma, :instance,
name: "Pleroma",
email: "admin@email.tld",
limit: 5000,
registrations_open: true
config :pleroma, :media_proxy,
enabled: false,
redirect_on_failure: true,
base_url: "https://cache.domain.tld"
# Configure your database
config :pleroma, Pleroma.Repo,
adapter: Ecto.Adapters.Postgres,
username: "pleroma",
password: "pleroma",
database: "pleroma",
hostname: "postgres",
pool_size: 10
```
You need to change at least:
- `host`
- `secret_key_base`
- `email`
Make sure your PostgreSQL parameters are ok.
You can now build the image. 2 way of doing it:
```sh
docker-compose build
# or
docker build -t pleroma .
```
I prefer the latter because it's more verbose.
Setup the database:
```sh
docker-compose run --rm web mix ecto.migrate
```
Get your web push keys and copy them to `secret.exs`:
```
docker-compose run --rm web mix web_push.gen.keypair
```
You will need to build the image again, to pick up your updated `secret.exs` file:
```
docker-compose build
# or
docker build -t pleroma .
```
You can now launch your instance:
```sh
docker-compose up -d
```
Check if everything went well with:
```sh
docker logs -f pleroma_web
```
You can now setup a Nginx reverse proxy in a container or on your host by using the [example Nginx config](https://git.pleroma.social/pleroma/pleroma/blob/develop/installation/pleroma.nginx).
### Update
By default, the Dockerfile will be built from the latest commit of the `develop` branch as Pleroma does not have releases for now.
Thus to update, just rebuild your image and recreate your containers:
```sh
docker-compose pull # update the PostgreSQL if needed
docker-compose build .
# or
docker build -t pleroma .
docker-compose run --rm web mix ecto.migrate # migrate the database if needed
docker-compose up -d # recreate the containers if needed
```
If you want to run a specific commit, you can use the `PLEROMA_VER` variable:
```sh
docker build -t pleroma . --build-arg PLEROMA_VER=develop # a branch
docker build -t pleroma . --build-arg PLEROMA_VER=a9203ab3 # a commit
docker build -t pleroma . --build-arg PLEROMA_VER=v2.0.7 # a version
```
`a9203ab3` being the hash of the commit. (They're [here](https://git.pleroma.social/pleroma/pleroma/commits/develop))
## Other Docker images
Here are other Pleroma Docker images that helped me build mine:
- [potproject/docker-pleroma](https://github.com/potproject/docker-pleroma)
- [rysiek/docker-pleroma](https://git.pleroma.social/rysiek/docker-pleroma)
