Playbooks

Playbooks to migrate

These are playbooks that we should be migrating over to ooni/devops, either
as-is or consolidating them together into one.

They are loosely sorted by priority:

• #341
• ansible-version.yml -> it would be nice to have a hook to send a message when we do a deploy to slack done in https://github.com/ooni/devops/pull/118
• deploy-backend.yml -> migrate: https://github.com/ooni/devops/pull/119
• deploy-monitoring.yml -> migrate: https://github.com/ooni/devops/pull/118
• deploy-slackin.yml -> last update 2021, requires migration since it's our slack inviter host
• deploy-countly.yml
• deploy-th-echo.yml -> last update 2019, we need to setup a new one
• deploy-th-http.yml
• deploy-vpsprobes.yml -> last update 2023, would be nice to have something like this for deploying ooniprobe on vps
• deploy-oonidata.yml
