cloudinfra project is a very special project intended to hold infrastructure relating to running the rest of Cloud VPS. Access to it is restricted under Help:Access policies.
Types of instances it contains currently:
These instances are important! They serve the rest of Cloud VPS with NTP updates.
These instances are important! They serve the rest of Cloud VPS with outbound mail handling.
These instances are a work in progress. See phab:T171188
These instances are a work in progress. See phab:T219428
They are currently m1.small. One will replicate from the other as a backup, it should not be on the same physical host.
This instance is a work in progress. Will be a project-puppetmaster for (some of) the cloudinfra project instances. To be used to serve secrets to cloud-puppetmaster and cloudinfra-db hosts, and potentially mx-out in the event that e.g. DKIM keys are added there in future. No plans to be used with the ntp instances.
This is currently m1.small.
This project also has an important role with regards to DNS. See Portal:Cloud_VPS/Admin/DNS for more info.
The equivalent of this project in the codfw1dev deployment is called cloudinfra-codfw1dev, and has the same role within the deployment.
