amazon-ecr-credential-helper
A credential helper tool for Docker that automates the refresh of ECR authorization tokens.
- unauthorized: authentication required (AWS ECR docker pull and push)
Fixes ECR 'unauthorized: authentication required' on docker pull/push. Use when AWS Elastic Container Registry rejects the daemon because the login token expired (12h lifetime) or was never issued. Not for Docker Hub credential errors.
