Resource Requirements
To ensure a successful DKP install, there are certain requirements to be met in regards to Control Plan nodes as well as Worker nodes. These resource requirements can be slightly different for different Infrastructure Providers.
The specific infrastructure provider resources are listed in their install sections which are referenced below.
General Resource Requirements
To Install DKP with the correct amount of resources, please see the list below before beginning installation.
Control Plane Nodes
You must have at least three control plane nodes. Each control plane node should have at least:
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
.Disk usage must be below 85% on the root volume.
If you use the instructions to create a cluster using the DKP default settings without any edits to configuration files or additional flags, your cluster is deployed on an Ubuntu 20.04 operating system image with 3 control plane nodes, and 4 worker nodes which match the requirements above.
Infrastructure Provider Specific
For Specific Infrastructure Providers additional requirements may apply. For example, 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. See Main Page for Provider for infrastructure provider specific additional resource information:
