I'm looking to understand log rotation mechanics. In /var/log/pods, I see that I mostly have files named 0.log. Sometimes I have 0.log and 1.log. In one case, I only have a 2.log. Did 0.log and 1.log rotate out? Will I eventually get a 3.log all by itself?

The number comes from the

Attempt

field in the container runtime config, which counts the number of times the kubelet has attempted to start that pod. https://github.com/kubernetes/kubernetes/blob/v1.34.1/staging/src/k8s.io/cri-api/pkg/apis/runtime/v1/api.pb.go#L1808-L1824

I see, good to know. Can you refer me to the code that handles writing and rotating the pod logs?

You'll have to dig through the guts of containerd for that

Got it, I found what I needed. Thanks for your help! Much appreciated, and have a nice weekend
