# 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.

|
## 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,
|
|
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 later 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 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=a9203ab3
|
|
```
|
|
|
|
`a9203ab3` being the hash of the commit. (They're [here](https://git.pleroma.social/pleroma/pleroma/commits/develop))
|
|
|
|
