@AkihiroSuda

Hi @AkihiroSuda, I have my local environment set up and I noticed --domainname is still listed as unimplemented in the original description. I would like to implement the --domainname flag for nerdctl run. I'll start working on the PR for this!

@mujii88

@mujii88 heads up before you start: --domainname is already implemented, has been since #3885 (Feb 2025) — it's wired up in container_run.go/container_run_network.go, flows through to container creation and labels, and is documented as implemented in command-reference.md line 202. It's only missing from the current unimplemented list, which is correct; the --domainname mention you saw is from the frozen old snapshot linked in this issue's original description, not the live docs. Might be worth picking something else off the actual current unimplemented list instead (--device-cgroup-rule, --health-start-interval, --link*, --storage-opt, --volume-driver).

Following up on my own comment from May: finally did the audit I said I would. Went through the current run unimplemented list (--device-cgroup-rule, --disable-content-trust, --health-start-interval, --link*, --storage-opt, --volume-driver) plus exec, attach, import, network inspect/network ls, volume create, and events against the actual flag registrations in the command implementations. Everything checked out accurate, no stale entries. #4809 already did a thorough pass back in March. No doc PR needed from this round, just wanted to close the loop rather than leave it hanging.
