Supported Kubernetes platforms
This version of VMware Postgres Operator is supported on the following platforms:
- VMware Tanzu Kubernetes Grid Integrated Edition ( TKGI), version 1.13.x - 1.16.x.
- Note: TKGI 1.13.0 and 1.13.1 clusters must be configured with the docker container runtime instead of the default containerd runtime due to an incompatibilty with the containerd provided. Existing clusters upgraded to TKGI 1.13 will continue to use the docker runtime. TKGI 1.13.2 is patched with version 1.5.9 of the containerd runtime to avoid the incompatibility issue.
- VMware Tanzu Kubernetes Grid (TKG), version 1.4.x - 1.6.x.
- Google Kubernetes Engine (GKE)
- Azure Kubernetes Service (AKS)
- Amazon Elastic Kubernetes Service (Amazon EKS)
- Red Hat Openshift - version 4.10+
- Kubernetes version 1.21+
IMPORTANT: Kubernetes is deprecating Docker as an underlying container runtime. If your environment uses containerd, avoid versions 1.5.6 and 1.5.7. There is a regression that blocks containers from being created if the image label key/value length is larger than 4096 characters.
You can check the container runtime for a Kubernetes cluster with:
kubectl get nodes -o wide
Minimum resource requirements
IMPORTANT: Use the minimum resource requirements as a guidance for resource constrained environments, or for test installations. Production systems should be sized according to your data needs, and workload expectations.
