To ensure a successful DKP install, there are certain requirements to be met. These resource requirements can be slightly different for different Infrastructure Providers.

The general resource requirements are listed after specific providers information.

Infrastructure Provider Specific

For Specific Infrastructure Providers additional requirements apply. An example would be that DKP on Azure defaults to deploying a Standard_D4s_v3 virtual machine with an 128 GiB volume for the OS and an 80GiB volume for etcd storage, which meets the above requirements. For additional information regarding your Infrastructure Provider, please see the related links below:

Amazon (AWS or EKS)

Microsoft Azure (Azure or AKS)

Google (GCP)

vSphere

Pre-provisioned

  • 4 cores

  • 16 GiB memory

  • Approximately 80 GiB of free space for the volume used for /var/lib/kubelet and /var/lib/containerd.

  • Disk usage must be below 85% on the root volume.

Worker nodes

You must have at least four worker nodes. The specific number of worker nodes required for your environment can vary depending on the cluster workload and size of the nodes. Each worker node should have at least:

  • 8 cores

  • 32 GiB memory

  • Around 80 GiB of free space for the volume used for /var/lib/kubelet and /var/lib/containerd.
