Containers

An opinionated collection of container images

Welcome to our container images, if looking for a container start by browsing the GitHub Packages page for this repo's packages.

Mission statement

The goal of this project is to support semantically versioned, rootless, and multiple architecture containers for various applications.

We also try to adhere to a KISS principle, logging to stdout, one process per container, no s6-overlay and all images are built on top of Alpine or Ubuntu.

Tag immutability

The containers built here do not use immutable tags, as least not in the more common way you have seen from linuxserver.io or Bitnami.

We do take a similar approach but instead of appending a -ls69 or -r420 prefix to the tag we instead insist on pinning to the sha256 digest of the image, while this is not as pretty it is just as functional in making the images immutable.

Container	Immutable
ghcr.io/drag0n141/sonarr:latest	❌
ghcr.io/drag0n141/sonarr:3.0.8.1507	❌
ghcr.io/drag0n141/sonarr:latest@sha256:8053...	✅
ghcr.io/drag0n141/sonarr:3.0.8.1507@sha256:8053...	✅

If pinning an image to the sha256 digest, tools like Renovate support updating the container on a digest or application version change.

Passing arguments to a application

Some applications do not support defining configuration via environment variables and instead only allow certain config to be set in the command line arguments for the app. To circumvent this, for applications that have an entrypoint.sh read below.

1. First read the Kubernetes docs on defining command and arguments for a Container.

2. Look up the documentation for the application and find a argument you would like to set.

3. Set the argument in the args section, be sure to include entrypoint.sh as the first arg and any application specific arguments thereafter.

   args:
     - /entrypoint.sh
     - --port
     - "8080"

Configuration volume

For applications that need to have persistent configuration data the config volume is hardcoded to /config inside the container. This is not able to be changed in most cases.

Available Images

Each Image will be built with a latest tag, along with tags specific to it's version. Available Images Below

Contributing

1. Install Docker, Taskfile & Cuelang

2. Get familiar with the structure of the repositroy

3. Find a similar application in the apps directory

4. Copy & Paste an application and update the directory name

5. Update metadata.json, Dockerfile, ci/latest.sh, ci/goss.yaml and make it suit the application build

6. Include any additional files if required

7. Use Taskfile to build and test your image

   task APP=sonarr CHANNEL=main test

Automated tags

Here's an example of how tags are created in the GitHub workflows, be careful with metadata.json as it does affect the outcome of how the tags will be created when the application is built.

Application	Channel	Stable	Base	Generated Tag
sonarr	develop	false	false	sonarr-develop:3.0.8.1538
sonarr	develop	false	false	sonarr-develop:latest
sonarr	main	true	false	sonarr:3.0.8.1507
sonarr	main	true	false	sonarr:latest

Deprecations

Containers here can be deprecated at any point, this could be for any reason described below.

1. The upstream application is no longer actively developed
2. The upstream application has an official upstream container that follows closely to the mission statement described here
3. The upstream application has been replaced with a better alternative
4. The maintenance burden of keeping the container here is too bothersome

Note: Deprecated containers will remained published to this repo for 6 months after which they will be pruned.

A lot of inspiration and ideas are thanks to the hard work of hotio.dev and linuxserver.io contributors, and onedr0p.
