This article presents a plan for running Software Factory on OpenShift.
Context and Problem Statement
We are looking for solutions to the following list of pain points with the current system:
- Where are the services secrets, and how can I rotate them? This is a key requirement for auditing purpose.
- The plateform is overloaded, what is the process to increase the number of executors?
- Zuul is not voting on $change_url, what is going on? (the service logs are presently not centralized)
- What base system should I use, CentOS? Fedora? Debian?
- How can I run a pre-production deployment with a local checkout of the Zuul source code?
- sfconfig execution is slow, for example sf-project.io deployment takes more than one hour to converge.
- [option 1] Modularize the Ansible roles
- [option 2] Migrate to Kubernetes
We would like to investigate if and how Kubernetes can be a solution. Here are the condition of satisfaction for the initial architecture:
When the user does not have a KUBECONFIG ready, sfconfig setup a single node cluster with Kind. Then the system requires a working kubectl command.
Using common manifests, the user can deploy custom architecture, for example kubectl apply -f zuul+ci-log-processor.yaml:
- Deploys: opensearch, zuul and ci log processor.
- Provides: zuul-web url and kibana url.
Running sfconfig develop ~/src/opendev.org/openstack/ci-log-processing restart the ci-log-processor service using a local copy of the source. See for example this guide: https://github.com/kubernetes-sigs/kind/issues/2430
Migration from sfconfig.yaml and arch.yaml
There is a procedure to migrate the legacy system.
