Week 44 2024 routine

[kiwixbot]

Check nodes free space

df -h / && df -h /data

• create a report in issue comment

Nodes system upgrades

apt update && apt upgrade

• run systematically the upgrade on bastion, stats, services, storage, demo, mirrors-qa nodes
• check for and apply important security upgrade on worker nodes asap (imager-worker, ondemand, sisyphus)

(regular workers updates are done separately on a monthly basis for worker nodes to not impact production)

Backups

• Ensure all borg repositories are being updated

k8s cluster

• Check Pod errors or in CrashLoopBackoff

k get pods -A -o wide|grep -E 'Error|Crash'

• Check Pod restarts

k get pods -A -o wide | pyp -i 'print("\n".join([line for line in l if re.split(r"\s+", line)[4] != "0"]))'

• Check if k8s should/could be upgraded

curl -s -H "X-Auth-Token: $SCW_SECRET_KEY" https://api.scaleway.com/k8s/v1/regions/fr-par/clusters/$KIWIX_PROD_CLUSTER | jq ".version,.upgrade_available"
curl -s -H "X-Auth-Token: $SCW_SECRET_KEY" https://api.scaleway.com/k8s/v1/regions/fr-par/versions | jq ".versions[].name"

• Upgrade k8s if applicable/possible

Stats

matomo - stats.kiwix.org

• Ensure download.kiwix.org stats are being recorded
• Check whether matomo should be upgraded

Grafana

• Alert list is normal
• Zimfarm dashboard is normal
• Jobs durations dashboard is normal
• There is no abnormal behaviors on cluster resources consumption
• All mdadm RAID arrays are OK (check all instances in the top left combobox)

Projects

• UptimeRobot has no alert
• zimit backlog is reasonable
• Cloud Code Signing Certificate usage is OK (look for Unused Signings under END ENTITY CERTIFICATES): we have 1,200 per year (August to August)
• Analyze zimit failed tasks
• PRs awaiting your review

Security

• Analyze/merge dependabot PRs

Note: this is an automatic reminder intended for the assignee(s).
