Buildah: Use `Buildah` in Ubuntu 16

[atefBB]

Description

I've installed buildah in Ubuntu Linux 16.04.3 following the installation instructions in the docs, when I run buildah images (e.g) I got the error: kernel does not support overlay fs: 'overlay' is not supported over extfs at "/var/lib/containers/storage/overlay": backing file system is unsupported for this graph driver !

Steps to reproduce the issue:

1. Install buildah in ubuntu 16
2. Run any buildah command

Describe the results you received:
The result: kernel does not support overlay fs: 'overlay' is not supported over extfs at "/var/lib/containers/storage/overlay": backing file system is unsupported for this graph driver.

Describe the results you expected:
Success !

@lsm5 any thoughts?

[lsm5]

@nalind @rhatdan overlay driver is dependent on newer kernel, yes? What's the right driver for older ones?

[rhatdan]

I would use the VFS driver, BTRFS and XFS might work. But we have not done a lot of testing on this.

[lsm5]

@atefBB I can send you a one-off deb file with this change if you'd be willing to test it

[atefBB]

@lsm5 Yes ! I can test it.

@rhatdan so is it just driver = "vfs" in this case?

[lsm5]

@atefBB can you try installing the containers-common deb file at https://lsm5.fedorapeople.org/containers-common_0.1.39-1~ubuntu16.04~ppa2_all.deb . That should install a new storage.conf with driver = "vfs" ... or better still, please make the change manually in your storage.conf first and check if that works

[rhatdan]

export STORAGE_DRIVER=vfs

Or --storage-driver vfs

[atefBB]

@lsm5 I'll try it !

[lsm5]

@atefBB any luck?

[atefBB]

@lsm5 I got this:

@atefBB I know @lsm5 has been doing a lot of work in the packaging department in terms of overlayfs. Is this still an issue with the latest versions of Buildah?

Getting our tools to build on 16.04 on OBS is a huge pain because of a very old golang. I'm hoping people can move to a newer Ubuntu version (18.04+), and a new LTS should be coming out soon as well.

[lsm5]

@atefBB have you had the chance to move to a newer Ubuntu? Can we close this?

[lsm5]

closing. @atefBB please re-open if need be.
