Docker skill signals
Evaluate the complete container workflow
Measure how candidates build, configure, run, connect, secure, and troubleshoot containerized applications in practical environments.
Docker fundamentals and architecture
Evaluate images, containers, registries, layers, Docker Engine, namespaces, isolation, and the container lifecycle.
Docker commands and container management
Test container creation, inspection, logs, execution, resource handling, cleanup, restart policies, and runtime configuration.
Dockerfiles and image optimization
Review build instructions, layers, caching, multi-stage builds, image size, build context, and secure image creation.
Docker networking and service communication
Assess bridge networks, custom networks, port publishing, DNS, container connectivity, isolation, and service discovery.
Volumes and persistent storage
Evaluate named volumes, bind mounts, storage persistence, permissions, backup considerations, and data-sharing patterns.
Docker Compose and troubleshooting
Measure multi-container configuration, dependencies, environment variables, health checks, logs, rebuilds, and deployment issues.
