     5  ## Overview
     6  
     7  This directory contains the Dockerfiles necessary to create the three podmanimage container
     8  images that are housed on quay.io under the Podman account.  All three repositories where
     9  the images live are public and can be pulled without credentials.  These container images are secured and the
    10  resulting containers can run safely with privileges within the container.  The container images are built
    11  using the latest Fedora and then Podman is installed into them:
    12  
    13    * 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](stable/Dockerfile).
    14    * 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](upstream/Dockerfile).
    15    * 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](testing/Dockerfile).
    16    * 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](https://bodhi.fedoraproject.org/) and the image is built from there.  For more details, see the Containerfile used to build it, [podmanimage/stable/manual/Containerfile](stable/manual/Containerfile).
    17  ## Sample Usage
    18  
    19  
    20  ```
    21  podman pull docker://quay.io/podman/stable:latest
    22  
    23  podman run --privileged stable podman version
    24  
    25  # Create a directory on the host to mount the container's
    26  # /var/lib/container directory to so containers can be
    27  # run within the container.
    28  mkdir /var/lib/mycontainer
    29  
    30  # Run the image detached using the host's network in a container name
    31  # podmanctr, turn off label and seccomp confinement in the container
    32  # and then do a little shell hackery to keep the container up and running.
    33  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'
    34  
    35  podman exec -it  podmanctr /bin/sh
    36  
    37  # Now inside of the container
    38  
    39  podman pull alpine
    40  
    41  podman images
    42  
    43  exit
    44  ```
