Flat Manager Docker Image

---

This repository contains the source for the docker container used to manage the elementary flatpak repository. It uses flat-manager for the API, but also includes modifications to make it optimal for running in kubernetes, and mount an S3 endpoint for file storage.

Most of this work is based of this WIP PR. Once that is merged, this repository will go down in size a lot.

Configuration

You will want to make a custom flat-manager configuration at place it at /var/run/flat-manager/config.json. Here is the example config:

{
    "repos": {
        "stable": {
            "path": "repo",
            "collection-id": "org.test.Stable",
            "suggested-repo-name": "testrepo",
            "runtime-repo-url": "https://dl.flathub.org/repo/flathub.flatpakrepo",
            "gpg-key": null,
            "base-url": null,
            "subsets": {
                "all": {
                    "collection-id": "org.test.Stable",
                    "base-url": null
                },
                "free": {
                    "collection-id": "org.test.Stable.test",
                    "base-url": null
                }
            }
        },
        "beta": {
            "path": "beta-repo",
            "collection-id": "org.test.Beta",
            "suggested-repo-name": "testrepo-beta",
            "runtime-repo-url": "https://dl.flathub.org/repo/flathub.flatpakrepo",
            "gpg-key": null,
            "subsets": {
                "all": {
                    "collection-id": "org.test.Beta",
                    "base-url": null
                },
                "free": {
                    "collection-id": "org.test.Beta.test",
                    "base-url": null
                }
            }
        }
    },
    "port": 8080,
    "delay-update-secs": 10,
    "database-url": "postgres://%2Fvar%2Frun%2Fpostgresql/repo",
    "build-repo-base": "build-repo",
    "build-gpg-key": null,
    "gpg-homedir": null,
    "secret": "c2VjcmV0"
}

S3 Repository

You can also mount an S3 location in the container to statically host the repository. Warning this comes with a lot of warnings and can possibly break at any time. Use at your own risk. goofys and catfs are installed by default in the flat-manager image.

NOTE You will also need to run the container with --privileged or you will end up getting an error like so

fuse: device not found, try 'modprobe fuse' first

To do this, simply add a script file at /var/run/flat-manager/startup.sh. This file will be ran on container startup. For instance:

export AWSACCESSKEYID="aws access key"
export AWSSECRETACCESSKEY="aws secret key"

mkdir -p "$HOME/repository"

/usr/bin/goofys flatpak-repository "$HOME/repository"
