Released nerdctl v1.0
After nearly two years of development, nerdctl (contaiNERD CTL) finally reached v1.0.0 🤓 (October 21, 2022) .
A huge thanks to more than 80 contributors, 4,600 stargazers, and an uncountable number of users, for making this possible! 🎉
How it started
I started the nerdctl project in December 2020 to facilitate experimenting eStargz with the same UI/UX as the docker command.
The initial commit was quite useless; it only had 4 commands (build, ps, pull, run) with 6 functional flags.
Since then, lots of commands and flags were implemented very quickly with the help from the community.
The important milestones include:
- v0.3 (Dec 2020):
nerdctl run --publish=<PORT> - v0.8 (Apr 2021):
nerdctl compose up - v0.9 (Jun 2021):
nerdctl run --gpus=<GPU> - v0.13 (Nov 2021):
nerdctl run --platform=<PLATFORM> - v0.19 (Apr 2022):
nerdctl cp - v0.22 (Jul 2022):
nerdctl system prune
The current release covers almost all non-swarm commands and flags of the docker CLI, except a few ones like nerdctl diff .
Recent updates
New lazy-pulling snapshotters
While nerdctl was originally written for experimenting the eStargz ( stargz ) snapshotter, nerdctl isn’t solely made for eStargz today. nerdctl supports other lazy-pulling snapshotters too:
overlaybd(since v0.15, thanks to Yifan Yuan ([@]BigVan))nydus(since v0.22, thanks to Nan Li ([@]loheagn))
The community is also looking forward to experimenting soci snapshotter in the near future.
New logging drivers
In addition to the default json-file driver, several additional logging drivers were contributed from the community:
journald(since v0.21, thanks to Fahed Dorgaa ([@]fahedouch))fluentd(since v0.21, thanks to Zheao Li ([@]Zheaoli)syslog(since v1.0, thanks to Hanchin Hsieh ([@]yuchanns))- External logging driver binaries (since v0.23, thanks to Manu Gupta ([@]manugupt1))
New network drivers
In addition to the default CNI bridge , the current release also supports macvlan and ipvlan (since v0.17.1). Thanks to Ye Sijun ([@]junnplus) .
Prune commands
Also thanks to Ye Sijun ([@]junnplus) for implementing nerdctl (container|image|volume|network|system) prune commands (v0.22.1).
Experimental suport for bypass4netns
v0.17 added the experimental support for bypass4netns which eliminates the overhead of the rootless networking stack (slirp4netns). The throughput can be 10x-100x faster, depending on the workload and the environment.
Thanks to Naoki Matsumoto ([@]naoki9911) for working on this during our (=NTT) internship program.
Lima joined the CNCF Sandbox
Lima joined the CNCF Sandbox to popularize containerd and nerdctl for Mac users.
The next release of Lima (v0.13) will be released very soon to deliver nerdctl v1.0 to the users.
containerd developers will get together at KubeCon
containerd developers will get together at KubeCon North America (Detroit).
