How to fix invalid image format in Kubernetes

KubernetesBEGINNERMEDIUM

This error occurs when a container image reference has invalid format.

What this error means

Kubernetes cannot parse image reference. Must follow [REGISTRY/]REPOSITORY[:TAG] format.

1Check image specification

Review pod YAML image field syntax and format

2Verify format rules

Image must follow [REGISTRY/]REPOSITORY[:TAG] format

3Fix reference

Remove invalid characters and fix format

4Apply manifest

kubectl apply -f deployment.yaml

Image parsing strict per OCI Spec. Docker Hub normalizes to docker.io/library. Use lowercase for registry.
