# Single-container Mastodon

Don't ever host things anywhere but on a domain that you own.

This violates all the docker best practices and puts the whole-ass app
inside a single container (including redis and postgres!) so that you can
easily bring up a sef-hosted mastodon on things like caprover in a single
"app" without having to worry about cross-container links.

This is scratching an itch: I really just wanted a one-command single-user
Mastodon instance.

# Features

* Ubuntu bionic
* Everything in one container, including a very minimal postfix, postgres,
  and redis
* assets are precompiled on startup
* all state is in one volume
* database migrations can be run at startup

# Build Variables

* `UID` - numeric userid for `mastodon` user that everything runs as
  (default: `991`)
* `GID` - numeric groupid for `mastodon` user that everything runs as
  (default: `991`)
* `REPO_URL`: url to repository to use (default:
  `https://github.com/tootsuite/mastodon.git`)
* `REPO_REV`: git revision to use (default:
  `c4118ba71ba31e408c02d289e111326ccc6f6aa2`, mastodon v3.0.1)

# Environment Variables

* `RUN_DB_MIGRATIONS` (default: `true`, set to empty string `""` to disable)
* `SIDEKIQ_WORKERS`: (default: `5`)
* others: https://github.com/tootsuite/mastodon/blob/master/.env.production.sample
# Volumes

* `/state` - everything lives in here, db, redis, static files, logs,
  everything

# Ports

* 3000: mastodon web (no tls, do that elsewhere)
* 4000: mastodon streaming

# Credits

All praise to wonderfall's earlier single-container mastodon:

* https://github.com/Wonderfall/docker-mastodon
* https://hub.docker.com/r/wonderfall/mastodon

(I only made this because it did not include postfix/postgres/redis.)

# Example captain-definition

For use with Caprover.  

(Note that the Netdata system monitor program that
ships with Capdata is **spyware**, and Capdata [refuses to address that they
are embedding spyware](https://github.com/caprover/caprover/issues/553), so
it is advisable that you do not enable the Netdata support when using
Caprover unless you enjoy your usage data being silently transmitted to
Google.)
