Docker images are immutable, layered filesystem and metadata artifacts used to create containers. Layer reuse can speed builds and pulls, but poorly ord…
Docker network modes change how a container obtains connectivity. Bridge networks provide separate network namespaces with virtual connectivity; host mo…
Runtime settings define resource constraints, capabilities, process identity, restart behavior, filesystem mounts and environment variables. Correct set…
Docker skills are strongest when demonstrated through reproducible images, optimized Dockerfiles, secure runtime configuration, Compose stacks, troubles…
A container is a runtime instance created from an image, with process state, writable layer, configuration, mounts, and network attachment. Container ch…
Publishing a container port maps a host address and port to a container port through the relevant network implementation. Reachability also depends on h…
Healthchecks describe a command or probe that indicates container health, while restart policies determine how the engine responds after process exit. H…
A Dockerfile declares the instructions used to construct an image, including base, files, dependencies, configuration and default process. Each instruct…
User-defined Docker networks provide name-based container discovery so applications can connect using service or container names instead of tracking dyn…
