Hey there! Ready to demystify containerization? Join us in this video where we dive into creating a container runtime from scratch using the Linux chroot syscall. We'll build our own basic container runtime using chroot to provide isolation.

Then we'll tackle Linux namespaces like PID, mount, network and more to further isolate our containers. We'll also explore control groups (cgroups) and how they allow restricting resources for containers like CPU, memory, disk I/O, and more.

Remember, containers are just regular Linux processes that use these techniques for isolation and resource control. We'll walk through building a simple container runtime using chroot, namespaces, and cgroups to provide a hands-on understanding of how containers work under the hood.

You'll learn about container images, Dockerfiles, and tools like Docker. We'll use Alpine Linux to build a minimal container and touch on concepts like dynamic vs static linking. By the end, you'll be a master of container internals and isolation concepts - no magic required!
