01Installing and your first containerInstall Docker, understand images versus containers, and run your first container in both foreground and background. Challenge 10 min 02Images and registriesTags name image versions, and registries such as Docker Hub store and share images. Challenge 12 min 03.dockerignore and build speedA small build context and a well-ordered Dockerfile keep rebuilds fast. Challenge 13 min 04Health checks and restart policiesHealth checks tell Docker whether a container is ready, and restart policies control recovery. Challenge 12 min 05Debugging containersLogs, exec, inspect and exit codes reveal what a container is actually doing. Challenge 12 min 06Images and containersAn image is a read-only template; a container is a running instance with a writable layer. Challenge 12 min 07A Dockerfile with good layersLayer order determines cache reuse; small runtime images reduce risk. Challenge 15 min 08Volumes, ports and networksContainers are disposable; data and connectivity need explicit design. Challenge 14 min 09Compose a real stackCompose describes services, networks and volumes in one reproducible file. Challenge 14 min 10Production containersSmall images, least privilege and scanning reduce the blast radius. Challenge 15 min
