Just Enough Docker to be Dangerous

Explore docker basics and container-based delivery by setting up an environment, launching containers, and using port mapping to publish applications and interconnected services.

Set up and validate a Docker environment by following official docs, installing Docker on Linux, macOS, or Windows, and validating with docker run and version checks.

Learn how to run your first container using an alpine image from Docker Hub, and understand registry, namespace, repository, tag, and the ephemeral container lifecycle with docker events.

Learn how to make containers persist by using interactive and tty options with -i and -t, and run them in the background with -d for long-running, detached containers.

Learn essential Docker container operations, including listing, renaming, inspecting, viewing logs, copying files, and exec inside containers, plus stopping and removing them.

Publish docker containers to external access by mapping container ports to host ports, exposing applications like nginx on port 80 and using docker run options for port mappings.

Replace heavy virtual machines with docker containers to create lightweight, persistent development environments using Ubuntu and CentOS images, including pulling, launching with bash, and lifecycle management.

Use Portainer's web console to manage local or remote docker environments from a browser, including containers, volumes, networks, and events.

Launch a complete multi-service application stack with Docker Compose using a single docker-compose.yml. Automate interdependent services, their discovery, and streamlined start-stop management.

Learn to build a custom docker image by modifying a running container, compiling a C application, and committing the changes with docker commit to a Docker Hub repository.

Automate image builds with a Dockerfile, replacing manual steps with a scripted build that reads instructions, creates containers, and tags images for publishing on Docker Hub.

Learn how a dockerfile primer uses from, run, and copy instructions to build images, create layers, expose ports, set work directory, and generate reusable images for containers.

Learn to run container images quickly and easily using Docker, the fastest way to deploy applications. Consider the comprehensive Docker course for deeper learning with a special offer.
