Kubernetes is built for containers, and it’s been doing that since it used to run docker as an engine for its containers. But what if you want to add VMs to the mix? After all, containers are ephemeral and don’t require fixed IPs as they shift the identity toward labels, but VMs on the other hand are tied to IP addresses and in some cases MAC addresses. This brings us to this blog about VM migration and IP preservation.

Once a year, the Icinga team goes for a team event somewhere about an hour or two away from the office. This year’s edition landed us at the Adventure Campus in Treuchtlichen, right in the middle of this year’s first heatwave. The heat was unbearable.

When an employee asks about a VPN error, a software license request, or a password reset process that changed last quarter, the agent's response is only as good as the knowledge base behind it. Gaps in that knowledge base show up as deflected tickets that bounce back to a human, generic responses that miss the specific issue, or silence on topics employees ask about every week.
