beginnerDocker Architecture, Engine, Daemon, Client & Registry
How would you secure access to the Docker daemon in production?
Never expose the daemon over plain TCP without TLS. Restrict the docker Unix group to trusted users (membership is equivalent to root). For remote access, use TLS client-certificate authentication or SSH-based contexts. For multi-tenant or CI environments, prefer rootless Docker or delegate orchestration to Kubernetes with proper RBAC instead of direct daemon access.
