buildah is a command line tool, to be installed and run on target,
that can be used to:
- create a working container, either from scratch or using an image
as a starting point
- create an image, either from a working container or via the
instructions in a Dockerfile
- images can be built in either the OCI image format or the
traditional upstream docker image format
- mount a working container's root filesystem for manipulation
- unmount a working container's root filesystem
- use the updated contents of a container's root filesystem as a
filesystem layer to create a new image
- delete a working container or an image
- rename a local container
Testing:
Setup the build directory:
$ . oe-init-build-env <build_dir>
Add to local.conf:
IMAGE_INSTALL:append = " buildah kernel-modules"
KERNEL_FEATURES += "features/overlayfs/overlayfs.cfgi \
features/netfilter/netfilter.scc \
features/lxc/lxc-enable.scc"
IMAGE_ROOTFS_EXTRA_SPACE = "5242880"
Build image:
$ bitbake core-image-minimal
Run the image:
$ runqemu nographic kvm qemuparams="-m 4096"
On target:
Pull an image:
> cnt=$(buildah from fedora)
Or build from Dockerfile
> buildah bud -t <image_name>:<tag> .
Mount the image:
> mnt=$(buildah mount ${cnt})
Install packages on the container rootfs:
> dnf install --installroot $mnt <packages_to_install> -y
Copy local files to the container:
> buildah copy $cnt <local_file> <dest_on_container>
Save the changes to an image
> buildah commit --format docker $cnt <name>:<tag>
Run the image using buildah:
> buildah run $cnt /bin/sh
Or using docker:
> docker run -it <name>:<tag>
I haven't forgotten about this, just with the storms and power outages
here in Ottawa, I'm running way behind in my patch processing.

Thank you for the update, I was about to ping you regarding this.
