podman docker image builder

This image can build container images from a Dockerfile. It uses centos 8 with podman.

using the image

Simply use registry.gitlab.com/kraxel/podman-docker-builder:latest instead of docker:latest in your .gitlab-ci.yml file. dind (docker-in-docker) is not needed and can be dropped. All your docker commands are automatically redirected to podman, so there is no need to change them all.

compatibility

The usual build workflow with pull / build / tag / push docker commands should work just fine. There isn't a docker daemon running though.

template

There is a template in this repo which you can use via include in .gitlab-ci.yml:

include:
  - project: 'kraxel/podman-docker-builder'
    file: 'gitlab-ci-template.yml'
