name: copy-logs-from-k8s description: Use when you need to download tikv/tiflash/s3clean logs from a Kubernetes cluster using scripts/copy_logs_from_k8s.py, including selecting specific sources and saving per-pod folders.

Copy Logs From K8s

Quick Start

• Ensure kubectl points to the target cluster.
• Run from the analysis directory so logs are saved there:

Copypython3 .codex/copy-logs-from-k8s/scripts/copy_logs_from_k8s.py

• Download specific sources:

Copypython3 scripts/copy_logs_from_k8s.py --sources tikv
python3 scripts/copy_logs_from_k8s.py --sources tikv,tiflash

• Or specify sources directly from the analysis directory:

Copypython3 .codex/copy-logs-from-k8s/scripts/copy_logs_from_k8s.py --sources tiflash

Outputs

• Logs are saved under ./<pod-name>/... in the current working directory.
• tikv: /var/lib/tikv/log
• tiflash: /data0/logs (uses container serverlog)
• s3clean: /tmp/s3clean.log -> ./<pod>/s3clean.log

Notes

• tiflash logs use kubectl exec ... cat because filenames can include : which breaks kubectl cp.
• Large log sets can take time to copy; re-run safely if interrupted.

Extend To Other Pods

• Edit scripts/copy_logs_from_k8s.py.
• Add the new source name to AVAILABLE_SOURCES.
• Add a LogSource(...) entry in sources within main():
  • Set pod_predicate to match pod names.
  • Use log_dir to copy a directory or single_file for one file.
  • Set container if the pod requires a specific container.
  • Set use_exec_copy=True if kubectl cp fails or filenames include :.
