Portal:Toolforge/Admin/Runbooks/HarborComponentDown

From Wikitech
Jump to navigation Jump to search

Overview

This happens when one of the Harbor components is down or not reporting being up.

This might make harbor unusable by toolforge and prevent any image from being pulled/pushed, making any non-cached run fail to start or build a new image for a tool.

It might prevent also from deploying some of the toolforge system components.

The procedures in this runbook require admin permissions to complete.

Error / Incident

This usually comes in the form of an alert in alertmanager.

There you will get which project (tools, toolsbeta, ...) is the one it's failing for, the harbor instance, and the component that is failing, or a message saying that none of them is reporting anything.

If none is reporting anything, it might be an issue with prometheus/alertmanager.

Debugging

You can ssh to the harbor instance directly and check there how/if it's running (use the instance of the project the alert is from):

$ ssh tools-harbor-1.tools.eqiad1.wikimedia.cloud
tools-harbor-1$ sudo -i
root@tools-harbor-1:~# cd /srv/ops/harbor/

You can try to restart/start it again, with docker-compose restart and docker-compose up -d.

You can also check the logs of each component with docker logs harbor-portal, where harbor-portal is the name of the component.
