In the Buildah images, we had a problem where the testing image was installed with an older version of Buildah than the stable image. This was apparently due to quay.io using Docker and Dockerhub which has a version of Fedora that did not let testing version of Buildah to be installed as it should have been. This change fully specifies the name of the fedora image to use. This has not been a problem in Podman, but I'm carrying this change here to avoid future problems.

podmanimage
Overview
This directory contains the Dockerfiles necessary to create the three podmanimage container images that are housed on quay.io under the Podman account. All three repositories where the images live are public and can be pulled without credentials. These container images are secured and the resulting containers can run safely with privileges within the container. The container images are built using the latest Fedora and then Podman is installed into them:
- quay.io/podman/stable - This image is built using the latest stable version of Podman in a Fedora based container. Built with podmanimage/stable/Dockerfile.
- quay.io/podman/upstream - This image is built using the latest code found in this GitHub repository. When someone creates a commit and pushes it, the image is created. Due to that the image changes frequently and is not guaranteed to be stable. Built with podmanimage/upstream/Dockerfile.
- quay.io/podman/testing - This image is built using the latest version of Podman that is or was in updates testing for Fedora. At times this may be the same as the stable image. This container image will primarily be used by the development teams for verification testing when a new package is created. Built with podmanimage/testing/Dockerfile.
- quay.io/podman/stable:version - This image is built manually using a Fedora based container. An RPM is first pulled from the Fedora Updates System and the image is built from there. For more details, see the Containerfile used to build it, podmanimage/stable/manual/Containerfile.
Sample Usage
podman pull docker://quay.io/podman/stable:latest
podman run --privileged stable podman version
# Create a directory on the host to mount the container's
# /var/lib/container directory to so containers can be
# run within the container.
mkdir /var/lib/mycontainer
# Run the image detached using the host's network in a container name
# podmanctr, turn off label and seccomp confinement in the container
# and then do a little shell hackery to keep the container up and running.
podman run --detach --name=podmanctr --net=host --security-opt label=disable --security-opt seccomp=unconfined --device /dev/fuse:rw -v /var/lib/mycontainer:/var/lib/containers:Z --privileged stable sh -c 'while true ;do sleep 100000 ; done'
podman exec -it podmanctr /bin/sh
# Now inside of the container
podman pull alpine
