Using Pods to run tools

We won't explore how to write a continuous deployment pipeline in this chapter. That is reserved for the next one. Right now, we are only concerned whether our Jenkins setup is working as expected. We need to know if Jenkins can interact with Kubernetes, whether we can run the tools we need as Pods, and whether they can be spun across different Namespaces. On top of those, we still need to solve the issue of building container images. Since we already established that it is not a good idea to mount a Docker socket, nor to run containers in privileged mode, we need to find a valid alternative. In parallel to solving those and a few other challenges we'll encounter, we cannot lose focus from automation. Everything we do has to be converted into automatic setup unless we make a conscious decision that it is not worth the trouble.
