Welcome to the Docker for Beginners Class0:45
Learn Docker basics to quickly build, test, and deploy applications with step-by-step, real-world lessons from a Docker expert, plus Q&A support.
Introduction to containers2:44
Compare virtual machines and docker containers, showing how containers use a host kernel and a container engine to run multiple apps without full guest operating systems.
Linux containers1:33
Understand Linux containers and how Docker Engine simplifies them, making containers lightweight by sharing the host kernel and not requiring a full operating system, building on LXC and LXD.
Demo - Installation of Docker5:44
Install docker on an ubuntu virtual machine, whether on cloud providers or local virtualization, using the get.docker.com script, connect via ssh with key-based authentication, and verify with docker --version.
Docker Architecture1:40
Explore the docker client and docker daemon architecture, learn how the docker server processes rest API calls, and see how docker commands like docker run enginex trigger the workflow.

Docker images and Docker Hub3:31
Understand docker images as blueprints containing the OS, file system, application, and dependencies to run containers, and use Docker Hub to find, publish, and pull images.
Docker Images0:06
Demo - Docker Images2:40
Pull and inspect docker images from Docker Hub using docker pull ubuntu, verify the latest tag, and note the image ID and size to understand why containers are lightweight.
Demo - Docker containers5:26
Learn to run docker containers from an ubuntu image with an interactive bash shell, detach without terminating the container, and inspect containers with docker ps -a.
Docker containers0:06
Demo - Docker container commands3:34
Learn essential docker container commands, such as running an interactive Ubuntu container, attaching and detaching, listing containers with docker ps and docker ps -a, and stopping or removing them.
Important Docker commands0:08
Running containers in detached mode4:09
run an nginx container with docker run, fetching the image from docker hub if needed, and use detached mode (-d) to run in the background; verify with docker ps -a.
PORT mapping4:35
Map the Docker host port to the container port to expose a containerized app via the VM public IP, e.g., 5000 to 80, and enable the port in cloud security.

Play with Docker1:56
Practice docker commands in an interactive playground that requires no installation, using a ready-made docker host to create images and run containers.
What are custom images3:47
Create custom images in Docker by writing a Dockerfile with from Ubuntu, copy, run, and cmd. Learn how each instruction adds a layer and how Docker build assembles the image.
COPY vs ADD instruction1:40
Compare copy and add instructions in dockerfiles, showing how copy moves files from host to image while add supports remote urls and automatic tar extraction.
Demo - Creating custom image5:53
Demonstrates creating a Python-based Docker image with a Dockerfile, using a base Python image, copy, and working directory, then building and running a container that prints a sample app message.
Demo: ADD instruction4:04
Demonstrates using the add instruction to copy a tar file into a docker image and auto extract it when a container runs, revealing example.txt.
ADD instruction - Important Note0:10
CMD vs Entrypoint instruction4:07
Understand the difference between cmd and entrypoint in a dockerfile. Cmd defines the run command on container start, while entrypoint fixes the command and appends parameters.

Image layer vs container layer6:23
Explore docker storage by distinguishing the image file system and the writable container layer, where image layers are read-only and the container layer stores changes using volumes for persistence.
Docker volumes5:34
Learn how Docker volumes persist data even when containers are deleted by creating, listing, inspecting, mounting with -v, and removing volumes, with data stored under var/lib/docker.
More on Docker Volumes
Docker volumes vs Bind Mounts2:15
Learn how to attach Docker volumes to containers and use bind mounts for host directories; Docker recommends volumes and the --mount flag with type, source, and target.

Docker Networking3:08
Explore docker networking and how containers talk to each other and to non-docker workloads. See default bridge, host, and none networks, and how docker0 assigns IPs on the bridge subnet.
Demo - Docker Networking3:24
List and inspect the default docker networks to reveal the bridge subnet 172.17.0.0/16 and the docker0 interface. Demonstrate running an alpine container to observe the bridge connection and IP assignment.

Docker Registry - Overview1:45
Explore Docker registry basics, including how Docker Hub serves as index.docker.io, how pulling and pushing images work, and the repository naming convention: username slash image name with an optional tag.
Demo - Docker Registry4:10
Learn how to create a Docker Hub account, build and tag a local image, log in, and push it to a Docker Hub repository using the docker.io registry.

Docker compose - overview2:22
Learn why docker compose is essential for multi-container apps by defining redis and web server services in a yaml file, enabling networks, volumes, and persistence with PostgreSQL or MySQL.
Demo - Docker Compose9:15
create and run a two-container python web app with docker compose (web container and redis cache), using a dockerfile, requirements.txt including flask, and a compose yaml to expose port 5000.
