Taming port-forwarding to k8s pods with SOCKS
Some times, especially during development, I need to connect to lot's of k8s pods using command-line curl (or other tools I have on my PC). The traditional solutions is to install a "jump-pod", and execute the commands there. Today I had enough and installed a socks proxy pod in the k8s cluster.
Deploying a docker-registry in your private kubernetes cluster
It is surprisingly hard to deploy a private docker registry anywhere, and kubernetes is no exception.
Deploying distcc in a kubernetes cluster to transform it into a big, fast build-machine.
For C++ developers, more cores to build on means faster builds. If your project is big, more cores can make a significant boost. If you have a local k8 cluster with spare CPU, it's amazingly simple to turn it into a build-machine.

How to share a private docker image or container securely
Some times it's required to copy a docker container between machines, or even developers. One option is to use a hosted repository and pay some money for this opportunity. Another option is to use a machine that has a reachable IP address and Docker to run a private and secure Docker Registry.
Building on Jenkins and deploying to a Docker container
Building something in Jenkins, using a declarative pipeline and deploying it to a Docker container is common, and you would expect it to be well documented and trivial to do right? Well, it is now.
