Azure Container Registry: unauthorized: authentication required, visit https://aka.ms/acr/authorization (AKS ErrImagePull 401)

Conflict. The container name "/x" is already in use by container …
A container (running or stopped) already has that name; Docker won’t create a second one with the same name.
the input device is not a TTY
docker run/exec was called with -t (allocate a terminal) in a context with no terminal — CI, cron, a pipe or a script.
ECS task stopped: CannotPullContainerError: pull image manifest has been retried ... / ref pull has been retried
The ECS task couldn’t pull its image — no network route to the registry, missing ECR permissions, or a wrong image tag.
exec /docker-entrypoint.sh: no such file or directory (CRLF line endings / missing interpreter)
The entrypoint file exists, but the kernel can’t run it — almost always Windows CRLF line endings in the script, or a shebang poi…
docker: invalid reference format (repository name must be lowercase)
Docker couldn’t parse the image name — uppercase letters, spaces, an empty variable, or a misplaced option.
Docker container is unhealthy (health check failing)
The container is running, but its HEALTHCHECK command keeps failing, so Docker (and dependent services) consider it unhealthy.
Docker container keeps restarting (Restarting (1) x seconds ago)
The container crashes on start and its restart policy (always/unless-stopped/on-failure) starts it again in a loop.

Spring Boot couldn’t bind its embedded server port because another process uses it.
bash: command not found
The shell can’t find an executable with that name in any directory on your PATH.
exec /entrypoint.sh: permission denied (container won't start)
The entrypoint or command isn’t marked executable inside the image, or it’s on a volume mounted noexec.
Docker container exits immediately (Exited (0) / Exited (1) right after start)
The container started and its main process finished at once, so the container stopped — Docker containers only live as long as PI…
fatal: not a git repository (or any of the parent directories): .git
You ran a Git command outside a Git working tree.
docker compose: services.x Additional property y is not allowed / yaml: line N: mapping values are not allowed

Kubernetes: CrashLoopBackOff
