CatOps Digest 2022-11-20
What happened on CatOps in the last two weeks…
There were not many posts on the channel in the last two weeks, but still.
Yet, if you’re interested in more technical news and discussions, check out my other little project - a list of Ukrainian IT communities and chats. I have created it a year or so ago to help others find like-minded people. If you know some cool community that is not represented there, feel free to contribute to this project on GitHub!

Voice Chat
Even though there were not that many news on the channel, we had our regular voice chat on Thursday. We have discussed implementation of Policies as Code using OPA (Open Policy Agent) as well as other tools such as Kyverno. We also briefly discussed security in Kubernetes and beyond. We also briefly touched the topic of writing documentation.
Here are some tools that were mentioned in our discussion:
Policy Controller overview - OPA implementation in GCP.
Aquasecurity Starboard - vulnerability scanner for Kubernetes. Keep in mind that currently this project is in the process of merging with Trivy - another security scanner from the same developer.
FairindsOps Polaris - ensure best practices in Kubernetes.
FairwindsOps Pluto - detect outdated API versions in Kubernetes manifests.
Renovate bot - automated dependency updates.
Rego: getting started - getting started with writing Rego policies for OPA.
Documentation related things:
Slab - a documentation engine (it’s super-expensive, though).
MkDocs - docs in Markdown.
Confluence-vim - a Vim plugin to write Confluence pages directly in Vim.
