07/20/2022, 9:47 AM"nerdctl image ls" lists my base image (smp/mqlua:dev), but I can not use it in a Dockerfile FROM command. What am I missing?

07/20/2022, 2:50 PMThis is the exact issue I was running into yesterday. I think @kind-iron-72902 indicated that some kind of external registry has to be used. I am starting to experiment with that now.

07/21/2022, 11:23 PM@best-accountant-68201 Is this a known issue with
nerdctlb
best-accountant-68201
07/21/2022, 11:26 PMThat needs configuring buildkitd to use containerd worker
buildkitd --oci-worker=false --containerd-worker=truef
fast-garage-66093
07/21/2022, 11:29 PMHmm, we are supposedly doing that already:
buildkitd_opts="--addr=unix:///run/buildkit/buildkitd.sock --containerd-worker=true --containerd-worker-addr=/run/k3s/containerd/containerd.sock --containerd-worker-gc --oci-worker=false"b

07/21/2022, 11:30 PMThe containerd namespace has to match too
It is “buildkitd” by default
Ideally it should be set to “k8s.io” maybe, but it is reported that kubelet may wipe “unused” images, so probably it should be set to “default” and call it a day

fast-garage-66093
07/21/2022, 11:33 PMYes, kubelet does garbage collection of unused images once some threshold is reached: https://kubernetes.io/docs/concepts/architecture/garbage-collection/#container-image-lifecycle
Is there a way to set the namespace from the commandline, or only via
buildkitd.tomlb
best-accountant-68201
07/21/2022, 11:35 PMonly via toml IIRC

07/22/2022, 12:00 AM@calm-application-66065 I've updated your Github issue on macOS using containerd, nerdctl build can not use local base images · Issue #2584 · rancher-sandbox/rancher-desktop with the information from this thread, but there isn't anything simple you can do right now to get it to work. It is also too late to get any non-critical bug fixes into the upcoming release, so this will have to wait a little longer. For the meantime setting up a local registry is probably the best workaround.
@best-accountant-68201 I'm somewhat confused as I don't see us running the
buildkitdnerdctl/etc/conf/buildkitd.confSorry I'm a bit scatter-brained, as I'm trying to debug 2 other issues right now

07/22/2022, 9:37 AMHow can I set those options in rancher desktop on macOS? I see no buildkitd.toml file.
If I can somehow change the buildkitd namespace on macOS, that would already be fine, if it will be fixed in an upcoming rancherdesktop release, even better.
Does buildkitd on macOS run in a container?
So does anyone have a suggestion how to edit buildkitd.toml on macOS?
