@mtrmac PTAL.

mtrmac

(Various questions from my previous review seem to remain outstanding.)

+	// host[:port]
+	// host[:port]/namespace[/namespace…]
+	// host[:port]/namespace[/namespace…]/repo
+	// host[:port]/namespace[/namespace…]/repo(:_tag|@digest)


Unlike containers-registries.conf(5), https://github.com/openshift/runtime-utils/blob/8b8348d80d1d1e7b6cf06fb009d5965e0b55baa2/pkg/registries/registries.go#L19 doesn’t currently support the :tag|@digest part; it can be a host[:port][[/namespace…]/repo] only.

(I don’t think single-image mirrors are worth worrying about… unless we needed to allow them now because we won’t be allowed to change the validation rules again?)

removed host[:port]/namespace[/namespace…]/repo(:_tag|@digest)

This seems incorrect, in that it allows *a.; wildcards are supported only with the exact *. prefix.

Even with the explanation, validating the regex feels like too much work (which I didn’t do now). Does the API annotation have any mechanisms that could help?

If not, building the regex from components somehow would be nice. Maybe something similar to the way https://github.com/containers/image/blob/main/docker/reference/regexp.go does it — that’s admittedly extreme in being literal, but it does have the nice property that it results in a Go program that can be reviewed in small pieces, and then run with a value.String() to get a pattern.

I don't see the kubebuilder doc has a mechanism helper for regex. I can use some containers/image helpers in goplayground here to define the pattern https://play.golang.org/p/NO9_2LmqPiu

@mtrmac could you have another round of review?

kikisdeliveryservice

@QiWang19 I think it makes sense to update this enhancement at some point to pick up the new template changes (8d07520) involving API extensions since this will be adding a new CRD

Template link for ref: https://github.com/openshift/enhancements/blob/master/guidelines/enhancement_template.md

QiWang19 · 2021-11-08T22:06:59Z

@mtrmac Could you review? Updated:

Mentioned registries.conf should support digest required mirrors and tags allowed mirrors in the separated list.
ImageContentPolicy API change to have new mirrorsByTgas for using mirror by tags.

Add CRD ImageDigestMirrorSet and ImageTagMirrorSet to have API for epics: - https://issues.redhat.com/browse/OCPNODE-521: different API for two saprate lists for digest image pull and tag image pull using mirrors. - https://issues.redhat.com/browse/OCPNODE-810: add an option for user to choose if the source of the mirror should be denied if the mirrors pull failed.

Thanks @QiWang19!

Looks good overall, mostly trivial typos.

(Noting that more discussion is happening in openshift/api#1126 .)

@rphillips @QiWang19 oc and oc-mirror is missing here, and both of those tools heavily rely on the current ICSP implementation for all of image mirroring, this also includes our docs. Based on below note I can assume that the node team will also handle all the appropriate changes for oc and oc-mirror, is that correct?

Yes, I will handle the related changes.
