GKE appears to be having a day allocating nodes so I'm not 100% sure this is working properly but should be a starting point. I also have an update to the VPC section I'll push tomorrow. |
This provides a Terraform configuration for deploying our Kubernetes clusters to GKE. We deploy an identical cluster to each of a list of regions, with one small node for admin purposes due to a requirement to not use spot instances for the main node group for the and two autoscaling groups one with small 8 core nodes for most jobs and one with bigger nodes for the more resource intensive ones. This is different to our current scheme where each cluster has a single node group and we direct jobs in Jenkins. With this scheme we allow the Kubernetes scheduler to place jobs, or we can still direct them to specific node sizes using nodeSelector in the jobs and the labels that are assigned to the nodegroups. This is a more Kubernetes way of doing things and decouples further from Jenkins. Signed-off-by: Mark Brown <[email protected]>
