Parallels K8S Restarts

Beren

Hi All,

I know this isn't really supported, but I'm doing the course on my MBP using Parallels and multiple 18.0.4 virtual machines. I've managed to get up to Chapter 3 successfully! That's cool. What's not is that when I shut my VMs down or change networks (moving from work to home wifi for example), the K8s configuration loses network connectivity...basically I have to reset both master and the minion node and start over again.

Is there a graceful way to shutdown and restore the cluster?

On the good side, it is great reinforcement for the learnings so far, but I can imagine it getting annoying soon.

Hi @Beren,
Are your VM IPs changing between restarts?
If not, you may need to just check your kubelet.service on all nodes, and make sure it is running.

Yes - the base IP addresses change when I move from one WiFi network to another.

I got at least a partial fix! Now when I restart the VM, I have the cluster reloading. You must comment out the swap line in /etc/fstab or k8s will not load up on restart.

Super happy to report that fixed the network issue too.

Glad to hear your issue is resolved. The overview section of the first lab exercise mentions the requirement to permanently disable swap on your nodes.
