[Qemu-devel] [PATCH v2 0/5] tests/docker: add podman support

[Marc-André Lureau]

Hi,

podman allows to run containers in a similar fashion as docker, but
without daemon or root privileges. Thank you podman!

There is a weird issue with getaddrinfo(), that I reported upstream
https://github.com/containers/libpod/issues/3535. For now, it is
worked around with extra socket_check_protocol_support() checks.

thanks

v2:
- add socket_check_protocol_support() to test-char
- keep TAP harness happy when socket_check_protocol_support() fails
- removed bad AI_ADDRCONFIG patch
- rebased

[Qemu-devel] [PATCH v2 1/5] docker.py: add podman support

[Marc-André Lureau]

Add a --engine option to select either docker, podman or auto.

Among other advantages, podman allows to run rootless & daemonless
containers, fortunately sharing compatible CLI with docker.

[Qemu-devel] [PATCH v2 2/5] tests/docker: add podman support

[Marc-André Lureau]

Allow to specify the container engine to run with ENGINE variable.

By default, ENGINE=auto and will select either podman or docker.

With current podman, we have to use a uidmap trick in order to be able
to rw-share the ccache directory with the container user.

With a user 1000, the default mapping is:
1000 (host) -> 0 (container).

So write access to /var/tmp/ccache ends will end with permission
denied error.

With "--uidmap 1000:0:1 --uidmap 0:1:1000", the mapping is:
1000 (host) -> 0 (container, 1st namespace) -> 1000 (container, 2nd namespace).

(the rest is mumbo jumbo to avoid holes in the range of UIDs)

A future podman version may have an option such as --userns-keep-uid.
Thanks to Debarshi Ray for the help!

[Qemu-devel] [PATCH v2 3/5] tests: specify the address family when checking bind

[Marc-André Lureau]

getaddrinfo() may succeed with PF_UNSPEC, but fail when more specific.

(this allows to skip some tests that would fail under podman)

Why not do this in docker.py (either as part of patch 1 or separately)?
 Also, can you document in a comment why this is not needed with docker?

Doing it in docker.py would probably mean parsing and tweaking
arguments given to Docker.run(). Since it's a "temporary" work around,
I would rather have it at the top-level caller, in the Makefile.

I am not very familiar with podman or docker, so I am not able to tell
you why docker does work by default.  @Debarshi Ray might know, as he
helped me finding a workaround.

On the other hand that splits the choice of docker vs. podman in two 
places, and Python is a better place to implement workarounds.

It's not hard to move the workaround there.  The "-u $(shell id -u)" 
option could be replaced by a "--run-as-current-user" option parsed by 
RunCommand, not unlike --add-current-user that BuildCommand already 
supports.

Something like this (untested of course :)):

podman doesn't seem to be widely packaged as of yet so I can't test it
on any of my systems.

Yeah I agree we should move this trickery away from the Makefiles.

The future is here! :)

Since Podman 1.4.0, released on 7th June 2019, you can use
--userns=keep-id instead of typing out the entire UID mapping. The
relevant Podman pull request is:
https://github.com/containers/libpod/pull/3196

Rishi

You need to mention the UID mapping via --uidmap arguments (or
--userns=keep-id) because you are using Podman without involving root
on the host anywhere. With Docker the daemon always runs as root. You
either run the user-facing client also as root (with sudo and such) or
you add your user to the special 'docker' group.

These days, very recently, rootless Docker is a thing too:
https://engineering.docker.com/2019/02/experimenting-with-rootless-docker/

However, I don't think that's what the QEMU test suite has been using. :)

When running rootless, you can only map your current UID from the host
into the new user namespace, and usually that gets mapped to UID 0
inside the namespace. Hence the need to override the UID mapping. This
limitation isn't present when root is involved on the host.

Read this commit message for some more details on exactly what happens
when you specify the UID mapping like that:
https://github.com/debarshiray/toolbox/commit/cfcf4eb31e14b3a3
