Jenkins X infrastructure
Jenkins X runs it’s infrastructure in Google Cloud Platform (GCP). We have 2 GCP projects
This is where the main infrastructure runs (the jobs triggered when a pull request is opened in any repository). Some details about the infrastructure are shown below
- GKE kubernetes version 1.21
- Spot instances to keep costs low
- n1-standard-2 with boot size 100 GB
- Cluster autoscaler scales the nodes between 1 and 5.
- We use terraform, an infrastructure as Code tool to manage the cluster using the google-jx module.
This project is only used for bdd testing. Test clusters are created here when a pull request is opened in the jx3-versions repository.
Test clusters are supposed to be transient, and are regularly gc’ed.
- If a test passes, then a clean up is performed at the end of the test run to delete the test cluster
- For a failed test, we have a cloud function scheduled to run every hour which deletes any left over clusters and cloud resources (persistent volumes, service accounts and secrets)
