ImagePullBackOff tekton pruner job

[lucas-dclrcq]

Hello,

I recently deployed the operator (version 0.74.0), and the tekton-resource-pruner job fails with an image pull backoff error :

Warning Failed 50m (x47 over 4h25m) kubelet Failed to pull image "gcr.io/tekton-releases/dogfooding/tkn:d1da68e766393c4b4eb162128f2c5fd2cee270828811a113fcda1e8a586e7471": rpc error: code = NotFound desc = failed to pull and unpack image "gcr.io/tekton-releases/dogfooding/tkn:d1da68e766393c4b4eb162128f2c5fd2cee270828811a113fcda1e8a586e7471": failed to resolve reference "gcr.io/tekton-releases/dogfooding/tkn:d1da68e766393c4b4eb162128f2c5fd2cee270828811a113fcda1e8a586e7471": gcr.io/tekton-releases/dogfooding/tkn:d1da68e766393c4b4eb162128f2c5fd2cee270828811a113fcda1e8a586e7471: not found

If i manually try on my computer, tag d1da68e766393c4b4eb162128f2c5fd2cee270828811a113fcda1e8a586e7471 does not exist :

Error response from daemon: manifest for gcr.io/tekton-releases/dogfooding/tkn:d1da68e766393c4b4eb162128f2c5fd2cee270828811a113fcda1e8a586e7471 not found: manifest unknown: Failed to fetch "d1da68e766393c4b4eb162128f2c5fd2cee270828811a113fcda1e8a586e7471"

But, as a sha256 it works :

docker pull gcr.io/tekton-releases/dogfooding/tkn@sha256:d1da68e766393c4b4eb162128f2c5fd2cee270828811a113fcda1e8a586e7471

Looks like there is an automation that updates the tag, and its missing the latest@sha256: prefix : #2461
