Docker DevOps Bootcamp: Projects, CI/CD, Interview Prep-2026

Discover the five main stages of a Docker container lifecycle—create, start, run (the running state), stop, and remove—plus how pause, kill, and restart commands manage containers.

Master docker image management by listing images, pulling with modern syntax, and inspecting image history to see how each image was built.

Learn to pull a specific docker image version using tags, compare latest vs named versions. Search images via the docker cli for apache httpd, JDK 17, and Jenkins variants.

Learn to authenticate with docker login via the cli using a password or personal access tokens, resolve docker login required errors (including limit exceeded), and manage token permissions securely.

Learn to run containers with docker run, list active and completed containers with docker ps and docker ps -a, and explore images such as hello world and BusyBox.

Run a Docker container in the background with docker run -d, keeping servers like nginx running while you work. Verify with docker ps and learn to stop and remove.

Compare docker create, run, start, and restart to understand their differences, use cases, and how they prepare, start, resume, or refresh containers.

Explore the real-time differences between Docker container create, run, start, and restart, with practical guidance on when to use each.

Name a docker container for clarity, run it in the background with a specific name using nginx image, then inspect it to view id, state, image, ports, and network addresses.

Pause Docker containers to suspend processes temporarily with Docker pause, then resume using the Docker Compose command during maintenance to free resources or handle disk input/output tasks without shutting down.

Learn two ways to enter a docker container: use docker run -it ubuntu bash at startup, or docker exec -it container bash inside a running container.

Master offline sharing of Docker images by saving to a tar with docker save and loading with docker load, enabling backups and transfers in air-gapped environments.

Access the dockerized application from a browser using port mapping (-p host port:container port) to map host ports 8080 or 81 to container port 80, and avoid conflicts.

Understand docker file components, from run copy add workdir cmd expose env entrypoint and how to build a reproducible, consistent image for easy sharing and deployment.

Create a basic ubuntu-based dockerfile using a from instruction and a cmd to echo hello world, then build with docker build and run the image to see the output.

Explore how the run command installs dependencies in a dockerfile, updating the ubuntu image with apt-get, installing git, and building and running the image with docker build and docker run.

Compare copy and add commands: copy moves local files into the container. Add supports external URLs and compressed archives, demonstrated with creating a tar archive and copying archive.tar into /app.

Build and run a Node.js app using a two-stage Dockerfile, install dependencies with npm install, and expose port 3000 to display hello from Docker tutorial multi-stage build.

Learn secure Docker login using passwords or personal access tokens to authenticate with Docker Hub, then create a custom image and push it.

Learn to pull a custom image from Docker Hub, manage images with docker ps, rm, and rmi, and use tags and versions to pull specific variants.

Explore Docker storage types including volumes, bind mounts, and temps, and learn how to persist data beyond containers, enable data sharing, and back up with practical use cases.

Explore Docker volumes, including named, anonymous, and read-only types, and learn how to create, attach, and manage persistent storage outside container lifecycles.

Explore docker volumes for data persistence by creating and listing volumes, mapping them to containers, and inspecting volume contents to persist files beyond container lifecycles.

Learn to remove unused docker volumes using docker volume rm, verify with docker volume ls, and remove blocking containers with docker rm to free the volume.

Learn how to create and manage Docker user defined networks, including bridge networks with customizable subnet ranges and inter-container communication via docker network connect.

Explore the new docker compose format, including optional version removal, file naming as compose.html or compose.yaml, optional project naming, and the unified docker compose command using space (docker compose up).

Learn to set up docker compose with a node.js app and redis database, creating dockerfile and docker-compose for web and database containers, exposing port 3000.

Learn how to specify the absolute path to a Dockerfile inside a Docker Compose file, enabling use of Dockerfiles located in subdirectories.

Learn to run a single container with Docker Compose by building a Python Flask app, writing a Dockerfile and a docker-compose file, and exposing port 5000 with its network.

Explore Docker Compose with a two-container setup using a Python Flask app and Redis to track page views, including building images, defining services, and port mappings.

Explore how Docker logging drivers control log capture and destination, including the default JSON file driver, centralized log management, and shipping to CloudWatch and Splunk.

Connect docker container logs to AWS CloudWatch by configuring IAM roles, the docker logging driver, and CloudWatch log groups, then run containers and see the logs.
