The hound project has undergone a small re-birth and moved to https://github.com/hound-search/hound which has broken our deployment. We've talked about leaving codesearch up to gitea, but it's not quite there yet. There seems to be no point working on the puppet now. This builds a container than runs houndd. It's an opendev specific container; the config is pulled from project-config directly. There's some custom scripts that drive things. Some points for reviewers: - update-hound-config.sh uses "create-hound-config" (which is in jeepyb for historical reasons) to generate the config file. It grabs the latest projects.yaml from project-config and exits with a return code to indicate if things changed. - when the container starts, it runs update-hound-config.sh to populate the initial config. There is a testing environment flag and small config so it doesn't have to clone the entire opendev for functional testing. - it runs under supervisord so we can restart the daemon when projects are updated. Unlike earlier versions that didn't start listening till indexing was done, this version now puts up a "Hound is not ready yet" message when while it is working; so we can drop all the magic we were doing to probe if hound is listening via netstat and making Apache redirect to a status page. - resync-hound.sh is run from an external cron job daily, and does this update and restart check. Since it only reloads if changes are made, this should be relatively rare anyway. - There is a PR to monitor the config file (https://github.com/hound-search/hound/pull/357) which would mean the restart is unnecessary. This would be good in the near and we could remove the cron job. - playbooks/roles/codesearch is unexciting and deploys the container, certificates and an apache proxy back to localhost:6080 where hound is listening. I've combined removal of the old puppet bits here as the "-codesearch" namespace was already being used. Change-Id: I8c773b5ea6b87e8f7dfd8db2556626f7b2500473 |
