Docker exec without Docker
Ever wondered what happens after you type docker run? Or did you know you can docker exec into a container without docker? We will try that in the talk using only native Linux commands! I will dive into the crucial parts of containers like groups, namespaces, and virtual ethernet bridges. Don’t have an idea what these things are? Then my talk is perfect for you! These are the low-level build blocks of what we know as a container. After this talk, you will have a whole different understanding of containers and why they aren’t even that special (even though they are pretty cool).
Docker network without Docker
Ever forgotten to add a port forwarding rule in Docker? Annoying to restart the container, right? But how does port forwarding between a container and a host even work? What about container-to-container communication, and what exactly are virtual Ethernet bridges? Wait, how do cgroups and namespaces relate to all this?
Let’s continue my "Docker * without Docker" series and dive into the depths of Docker networking - without worrying too much about Docker itself. What does Linux offer? How can we build something like this from scratch? Maybe even directly in the terminal?
Join me for a hands-on exploration of the fundamentals and exciting details behind container networking!
