Can't pull container image. Wrong tag, private registry auth, or image doesn't exist.

generic

95% success Verify image name and tag exist: docker pull <image>:<tag> locally first
```
docker pull <image>:<tag> locally first
```
Sources: https://kubernetes.io/docs/concepts/containers/images/
92% success For private registries, create imagePullSecret and reference it in the pod spec
```
kubectl create secret docker-registry regcred --docker-server=<url> --docker-username=<user> --docker-password=<pass>
```
Sources: https://kubernetes.io/docs/tasks/configure-pod-container/pull-image-private-registry/
90% success Check Events: kubectl describe pod <name> to see the exact pull error
```
kubectl describe pod
```

Common approaches that don't work:

Use :latest tag to always get newest 65% fail
:latest may not exist or may be outdated — use specific version tags
Disable image pull policy 95% fail
imagePullPolicy: Never tells kubelet to never pull the image. If the image is not already present on the node, the pod fails deterministically with ErrImageNeverPull. This does not solve pull errors — it only works when images are pre-loaded via docker load or a DaemonSet.
