Deployment server

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

Service

As of March 2021 the deployment servers are:

• deploy1002, used when Eqiad cluster is primary.
• deploy2002, used when Codfw cluster is primary.

There is also a service alias deployment.eqiad.wmnet which will point to the currently active server (regardless of data centre).

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
