Release v2.0.0-rc.3 · containerd/nerdctl

Changes

nerdctl v2 enables "detach-netns" for Rootless mode by default (#2723).

This will bring:

Faster and more stable nerdctl pull, nerdctl push, nerdctl build, etc
Proper support for nerdctl pull 127.0.0.1:.../...
Proper support for nerdctl run --net=host

Depends on RootlessKit >= v2.0 and BuildKit >= v0.13 (included in nerdctl-full-*.tar.gz).

Note

After upgrading nerdctl (rootless mode) from v1.x to v2.x, it is highly recommended to
re-install the systemd units and the configurations:

containerd-rootless-setuptool.sh uninstall
rm -rf ~/.config/{nerdctl,buildkit}
containerd-rootless-setuptool.sh install
CONTAINERD_NAMESPACE=default containerd-rootless-setuptool.sh install-buildkit-containerd

Other major changes:

nerdctl run:
- Added --systemd flag for running systemd in containers flag (#2785, thanks to @sazzy4o)
- Added --ipc=(shareable|container:<container>) flag (#2757, thanks to @minuk-dev)
- Added --annotation flag (#2906)
  - Now nerdctl run --label is only set as a containerd label and not propagated as an OCI annotation. A label with the nerdctl/ prefix can no longer be set manually, with an exception for nerdctl/bypass4netns. The nerdctl/bypass4netns label is still allowed and is propagated to an OCI annotation, for sake of compatibility.
- Added --sig-proxy flag (#3043, thanks to @CodeChanning)
- Propagate image labels to container labels (not to container annotations) (#3023, thanks to @yankay)
- Added --attach flag (#3157, thanks to @CodeChanning)
- The restriction for --name is relaxed to support longer names (#3279, thanks to @Shubhranshu153)
- Added --security-opt systempaths=unconfined flag (#3533, thanks to @austinvazquez)
- Added --network ns:<PATH> flag (#3538, thanks to @dancavallaro)
- Added the support for oci-layout image references (#3537, thanks to @austinvazquez)
nerdctl build:
- Added --attest, --sbom, and --provenance flags (#2786, thanks to @yankay)
- Added --pull flag (#3074, thanks to @sondavidb)
- Added the support for Windows (#2587, thanks to @TBBle)
- Added the support for oci-layout build contexts (#3327, thanks to @austinvazquez)
nerdctl ps:
- JSON type of --format=json is changed for better Docker compatibility (#2987, #3058, thanks to @apostasie and @yankay)
nerdctl inspect:
- Added --size flag (#3021, thanks to @apostasie)
nerdctl network:
- The networks are now aware of containerd namespaces. i.e., nerdctl --namespace=foo network list no longer shows networks created with nerdctl --namespace=bar network create (#3096, thanks to @apostasie)
- Enhanced support for DHCP (#3001, thanks to @apostasie)
nerdctl compose up:
- Added --abort-on-container-exit flag (#2873, thanks to @alegrey91)
nerdctl builder prune:
- Added --all flag (#3316, thanks to @austinvazquez)
- Added --force flag (#3316, thanks to @austinvazquez)
nerdctl image prune:
- Added --filter flag (#3319, thanks to @austinvazquez)
nerdctl image load:
- Added --quiet flag (#3551, thanks to @austinvazquez)
nerdct-full:
- Updated the components. See the Included components below.
- Removed IPFS (Kubo). Can be still installed manually. (#3532, thanks to @yankay)
Misc:
- Refactoring and stability improvements (Many PRs, thanks to @apostasie et al.)
And more!
