Deployment servers are servers used for deployment of software using Scap and scap3.

Service

As of June 2021 the deployment servers are:

There is also a service alias deployment.eqiad.wmnet which always points to the currently active deployment (Yes, this shortcut does the right thing, despite having "eqiad" in its name).

How to setup a deployment server in a cloud VPS project

  • create a new cloud VPS instance of size m1.small (or m1.medium if you will be deploying many scap3 projects)
  • in Horizon apply the puppet 'role::deployment_server' on the instance
  • Create and attach an extra storage volume on /srv to hold the software you are going to deploy
  • in the operations/puppet repo in ./hieradata/labs/yourproject/common.yaml or in Horizon add Hiera key/value pairs:

  • adjust the deployment::server::rsync_host value to a host in your project
  • adjust scap::sources to contain the scap3 projects you will be deploying
  • run puppet (a couple times)
  • run sudo -u trebuchet /usr/bin/scap deploy --init inside each of the repos under /srv/deployment/, so for example in /srv/deployment/gerrit/gerrit and so on but NOT in /srv/deployment/ directly.
  • run git init in /srv/deployment
  • run puppet again
