Kubernetes: ImagePullBackOff / ErrImagePull
The node can’t pull the container image — wrong name/tag, missing registry credentials, or registry unreachable.
denied: Your authorization token has expired. Reauthenticate and try again. (Amazon ECR)
Docker’s login to Amazon ECR has expired — ECR tokens last 12 hours, so pushes and pulls fail until you log in again.
manifest for image:tag not found: manifest unknown
The repository exists, but the tag you asked for doesn’t — it was never pushed, was deleted, or is misspelled.
Git: ! [rejected] … (fetch first) — error: failed to push some refs
The remote branch has commits you don’t have locally, so Git refuses to overwrite them. Pull (merge or rebase) first, then push.

GitHub no longer accepts account passwords for Git over HTTPS.

docker login authenticated, but the credential helper (keychain, pass, wincred) couldn’t store the password.
