Package: podman Version: 4.3.1+ds1-8+b1 Severity: normal X-Debbugs-Cc: hri...@venev.name
Dear Maintainer, When trying to run a container using podman (as root) with a uid/gid mapping specified via `--userns`, it fails to start: > # podman run --rm --userns auto:uidmapping=1000:1001:1,gidmapping=1000:1001:1 > debian:12 > ERRO[0000] Unmounting > /var/lib/containers/storage/overlay/INSERT_ID_HERE/merged: invalid argument > Error: mounting storage for container INSERT_ANOTHER_ID_HERE: creating > overlay mount to /var/lib/containers/storage/overlay/INSERT_ID_HERE/merged, > mount_data="lowerdir=/var/lib/containers/storage/overlay/INSERT_ID_HERE/mapped/0/l/INSERT_SHORT_ID_HERE:/var/lib/containers/storage/overlay/INSERT_ID_HERE/mapped/0/l/diff1:/var/lib/containers/storage/overlay/INSERT_ID_HERE/mapped/0/l/INSERT_ANOTHER_SHORT_ID_HERE,upperdir=/var/lib/containers/storage/overlay/INSERT_ID_HERE/diff,workdir=/var/lib/containers/storage/overlay/INSERT_ID_HERE/work,,volatile": > permission denied The following appears in the kernel log: > [TIME] overlayfs: failed to resolve > '/var/lib/containers/storage/overlay/INSERT_ID_HERE/mapped/0/l/INSERT_SHORT_ID_HERE': > -13 The outcome is listed above. The expected outcome was that the container would start, with most IDs mapped from those delegated to the `containers` user, except uid/gid 1000 inside the container which correspond to 1001 outside. Running the container with just `--userns auto` works. However, then all files passed to the container via bind mounts would be owned by nobody:nogroup instead of 1000:1000. This seems similar to https://github.com/containers/podman/issues/18435, which was probably fixed in podman 4.5.0. -- System Information: Debian Release: trixie/sid APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 6.3.0-1-amd64 (SMP w/24 CPU threads; PREEMPT) Locale: LANG=C.UTF-8, LC_CTYPE=C.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) Versions of packages podman depends on: ii conmon 2.1.6+ds1-1 ii crun 1.8.5-1 ii golang-github-containers-common 0.50.1+ds1-4 ii libc6 2.37-6 ii libdevmapper1.02.1 2:1.02.185-2 ii libgpgme11 1.18.0-3+b1 ii libseccomp2 2.5.4-1+b3 ii libsubid4 1:4.13+dfsg1-1+b1 Versions of packages podman recommends: pn buildah <none> pn catatonit | tini | dumb-init <none> pn dbus-user-session <none> pn fuse-overlayfs <none> pn slirp4netns <none> pn uidmap <none> Versions of packages podman suggests: pn containers-storage <none> pn docker-compose <none> ii iptables 1.8.9-2 -- no debconf information _______________________________________________ Pkg-go-maintainers mailing list Pkg-go-maintainers@alioth-lists.debian.net https://alioth-lists.debian.net/cgi-bin/mailman/listinfo/pkg-go-maintainers
