Best Practices¶
When choosing a container registry, consider integration with your cloud provider — AWS ECR integrates seamlessly with ECS and EKS, Azure ACR with AKS. For on-premise or multi-cloud deployments, Harbor is the best open-source choice with support for vulnerability scanning, cross-registry replication, and RBAC.
Every Docker image should go through a vulnerability scan before production deployment. Implement an admission controller in Kubernetes (such as OPA Gatekeeper) that rejects deployment of unsigned or unscanned images. Multi-stage builds in Dockerfiles reduce the final image size and lower the attack surface. Set up garbage collection for automatic cleanup of unused layers and tags.
