Linux Containers, more than just Docker

Explore the history of container technologies from CH root isolation in 1979 to modern runtimes like runC and containerd, highlighting namespaces, cgroups, LXC, seccomp, and OCI standards.

Install Docker runtime engine on your Linux distribution, using Fedora as an example. Enable service, add your user to the docker group, and use docker pull, docker run, docker ps.

Explore how Docker networking creates virtual container networks, comparing bridge, host, none, macvlan, IP VLAN, and IP net, and learn to route, isolate, and manage traffic.

Create a free docker hub account, build a simple nginx container with a dockerfile, tag it, push to the registry, then pull and run it locally, and enable two-factor authentication.

Demonstrate containerd mounts and access the host file system from containers via the default namespace, ctr tasks, and init pid; browse root directories and available images.

Explore Podman as a rootless, daemonless container runtime with a Docker-like CLI. Build, run, search images, and push unprivileged containers to OCI registries for secure CI workflows.

Learn to create and manage podman volumes, mount them into containers, access and share data across multiple containers, and back up or export volumes for production and recovery.

Discover Portainer, an open source web interface that manages Docker containers, images, networks, and volumes with templates, event management, and access control.

Install Portainer on your local Linux lab using deployment wizard and business edition license, then create data volume, mount docker socket, and expose ports 8009 and 443 to manage containers.

Learn to speed up Docker builds by enabling BuildKit, using DOCKER_BUILDKIT=1 or configuring the daemon.json buildkit setting, and leverage cached layers for faster rebuilds.
