*TL;DR: new OpenShift instance is up and running for CentOS CI, migrate
your workloads by March 31st, 2023. Test your access to both the Duffy API
and the new OpenShift instance by the end of 2022. CentOS CI changes
approaching the end of Phase 3.  *

Hello everyone,

We are happy to announce that the new OpenShift instance is up and running
(ticket [0]). For the tenants that opted in to continue using CentOS CI,
you are being required to *migrate your workload to the new OpenShift
instance by the end of Q1CY23*, with the final deadline being *March 31st,

In order to support you through the migration process, the team has created
a quick guide that can be found in [1].

We would also like to request you test your access to both the Duffy API
and the new OpenShift instance by the *end of 2022*. Please reach out to us
in case it is not working.

Here is the link to the new OCP cluster [2]. As a reminder, this new OCP
cluster is running in AWS, on top of EC2 instances, so coming with
different limitations when compared with “on-premises bare-metal OCP
deployments”. One notable change is that it is not possible to expose
/dev/kvm and so there is no way for tenants to deploy VMs through OpenShift
(like with the kubevirt operator or else). Tenants having a need to use VMs
can then request some through Duffy API.

Finally, here's a friendly reminder of the CentOS CI changes' current

According to our previous communications [3], we are approaching the end of
the last phase of the changes that have been implemented to CentOS CI.

*Phase 3 - Decommission*

   - Legacy/compatibility API deprecated and requests (even for EC2
   instances) will no longer be accepted
   - All tenants that opted in will be using only EC2 for aarch64/x86_64
   and on-premise cloud for ppc64le

For a full description of the project phases, you can check [3].

Please, feel free to reach out to us in case you have any questions or
