chainctl images discover

Find Chainguard replacements for the images your project uses.

Synopsis

Find Chainguard replacements for the images your project uses.

Reads every image reference under DIR (default: the current directory). For each upstream image, it reports whether Chainguard publishes a hardened replacement and whether your organization can pull it today.

Private-registry references are supported. An exact catalog alias is preferred. Otherwise, repository suffixes are tried from most to least specific. Thus registry.example/cache/dotnet/sdk retains dotnet/sdk, while a reference ending in nginx can still suggest Chainguard’s nginx. Namesake matching identifies a catalog offering, not identical image contents.

Both what you build and what you run are covered: Dockerfile FROM instructions, Kubernetes manifests, Compose files, Helm values, Terraform, shell scripts and Makefiles.

Helm values are read as written, not rendered. An image assembled from registry, repository, tag and digest keys is resolved. This includes a chart-wide imageRegistry or imageNamespace and an empty tag standing for the chart’s appVersion. A reference computed inside templates is beyond what reading values can see, so treat the result as what values declare.

Your immutability choice stays as written: a digest-pinned reference comes back digest-pinned. A maintained tag is kept. A variant or older patch resolves to its maintained version line when possible. An untagged reference is made explicit as latest, which is what Docker already uses. When no requested version is maintained, the suggestion uses a maintained latest tag. An image not yet entitled is named with a tag because its digest cannot be resolved until it is in your catalog.

Every reference is listed with what you can do: pull the replacement today, ask for entitlement, nothing (already on Chainguard), or nothing to move to. What has no replacement is as much of the answer as what does.
