RootlessKit v2 added the support for `--detach-netns` mode. This leaves containerd and buildkitd in the host netns so as to: - Eliminate the slirp overhead for pull/push - Allow accessing the real localhost registry. Since rootless users has no `CAP_NET_ADMIN` in the host netns, CNI plugins have to be executed in the "detached" netns (`$ROOTLESSKIT_STATE_DIR/netns`) that is associated with slirp. ref: - rootless-containers/rootlesskit PR 379 - containerd/nerdctl PR 2723 Signed-off-by: Akihiro Suda <[email protected]>
