View flow logs in the Calico Whisker web console.

i’ve been mucking about with calico on my #homelab #kubernetes cluster, and it took me far far too long to visit the whisker console: https://docs.tigera.io/calico/latest/observability/view-flow-logs

this is unbelievably helpful for debugging firewall rules

i’m very tempted to switch to calico on my non-k8s systems now (e.g. Linux gaming PC), so i can be back to only having 1 firewall abstraction in my brain

    I just installed Ciliium (another Kubernets CNI), and it also comes with a host based firewall, and an observability tool.

    I didn’t have Hubble (observability tool enabled), but I previously didn’t have a firewall, and I finally decided to enable it, which caused my ceph deployment to fail. This will help me figure out where it is failing and what rules are needed to remediate it.
