A simple kubectl plugin that replicates some of the logic of crane to do
Kubernetes things in the context of a kubectl plugin.
Currently all this supports is a subset of commands to simplify setting up registry credentials as pull secrets, and optionally pairing them with service accounts.
This operates like any other kubectl plugin (ref).
go install github.com/joshrwolf/kubectl-crane@latest
# Use it
kubectl crane --repo cgr.devCreate a secret with registry credentials
Usage:
crane [repository] [flags]
Examples:
Create a secret appropriate for pulling "cgr.dev/chainguard/chainguard-base:latest"
kubectl crane --ref cgr.dev/chainguard/chainguard-base:latest
Create a secret appropriate for pulling all images from "cgr.dev" and "gcr.io"
kubectl crane --repo cgr.dev --ref gcr.io/foo/bar
Create a secret in the "foo" namespace that all the default service accounts in the "foo" namespace can pull images from "cgr.dev"
kubectl crane --repo cgr.dev --sa default --namespace foo
Flags:
--as string Username to impersonate for the operation. User could be a regular user or a service account in a namespace.
--as-group stringArray Group to impersonate for the operation, this flag can be repeated to specify multiple groups.
--as-uid string UID to impersonate for the operation.

--name string The name of the registry credentials secret to create/update. (default "kc")

--ref strings The image reference to create the secret for. The repository will be inferred.
-r, --repo strings The repository to create the secret for
--request-timeout string The length of time to wait before giving up on a single server request. Non-zero values should contain a corresponding time unit (e.g. 1s, 2m, 3h). A value of zero means don't timeout requests. (default "0")
--sa strings The service account to patch.
-s, --server string The address and port of the Kubernetes API server
