List containerd's images: images list --context=<ctx>#24
Merged
Conversation
`y-cluster images list` overloads to read from a cluster's
k8s.io containerd namespace. Mutually exclusive with the
positional YAML input -- same conceptual question
("what images are in this scope?"), different source.
Output is one row per stored manifest (digest-aliases of
the same content fold together, the bare sha256:<hex>
config-digest row containerd writes is filtered out),
sorted by descending compressed size by default.
--sort=name switches to alphabetical; --format=json emits
[{ref, digest, size_bytes, size_human}] for piping.
Implementation parses `ctr -n k8s.io image list` tabular
output -- the same format pkg/images/load.go already
relies on -- and reads the SIZE column back from its IEC
units. Stable across the containerd versions y-cluster
targets without depending on ctr's --format json shape.
When many rows fold into one, refRank picks the most
informative form: name:tag@digest > name@digest > name:tag
> anything else. Hostport ":port" before the last slash
isn't counted as a tag (the standard containerd-ref edge
case stripTag already handles).

Bumps host bin (bin/y-bin.runner.yaml) and the in-cluster y-kustomize Deployment image across four consecutive y-cluster releases: - v0.4.2: `images load` accepts remote refs (Yolean/y-cluster#22) - v0.4.3: fix `images load` for digest-only refs (Yolean/y-cluster#23) - v0.4.4: `images list --context=<ctx>` subcommand (Yolean/y-cluster#24) and tunable Gateway API resource requests (Yolean/y-cluster#25) - v0.4.5: re-fix digest-only image tagging and gateway resource requests (Yolean/y-cluster#26) Image digest verified via `crane digest ghcr.io/yolean/y-cluster:v0.4.5`. sha256 sums copied from v0.4.5's checksums.txt.
