Rancher on vSphere with ESXi 6.7u2 and above If your DHCP options set is associated with a VPC that has instances with multiple operating systems, specify only one domain name.

However, other Linux operating systems and Windows treat the value as a single domain, which results in unexpected behavior. Some Linux operating systems accept multiple domain names separated by spaces. According to the DHCP options documentation: If you are configuring DHCP options sets for an AWS virtual private cloud, note that in the domain-name option field, only one domain name can be specified. Most cloud-hosted VMs already have this hotfix. You will also need to disable private IP address checks if you are using Amazon EC2, Google GCE, or Azure VM.įor VXLAN (Overlay) networking, the KB4489899 hotfix must be installed. For details, refer to the documentation on configuring cloud-hosted VM routes. Otherwise, you need to configure the route rules for them. The default option is VXLAN (Overlay) mode.įor Host Gateway (L2bridge) networking, it’s best to use the same Layer 2 network for all nodes. There are two network options: Host Gateway (L2bridge) and VXLAN (Overlay). Rancher only supports Windows using Flannel as the network provider. If you have not already installed Rancher, please refer to the installation documentation before proceeding with this guide. This is required in order for the cluster nodes to communicate with Rancher. Networking Requirementsīefore provisioning a new cluster, be sure that you have already installed Rancher on a device that accepts inbound network traffic.

Rancher will not provision the node if the node does not meet these requirements. The hosts in the cluster need to have at least:

If you are using GCE, Rancher recommends Windows Server 2019 Datacenter for Containers as the OS image.

If you are using AWS, Rancher recommends Microsoft Windows Server 2019 Base with Containers as the Amazon Machine Image (AMI).

Nodes with Windows Server core version 1903 should use Docker EE-basic 19.03.

Nodes with Windows Server core version 1809 should use Docker EE-basic 18.09 or Docker EE-basic 19.03.

In order to add Windows worker nodes to a cluster, the node must be running one of the following Windows Server versions and the corresponding version of Docker Engine - Enterprise Edition (EE): The general node requirements for networking, operating systems, and Docker are the same as the node requirements for a Rancher installation.

Tutorial: How to Create a Cluster with Windows Support.

Windows nodes must have 50 GB of disk space.įor the full list of requirements, see this section.įor a summary of Kubernetes features supported in Windows, see the Kubernetes documentation on supported functionality and limitations for using Kubernetes with Windows or the guide for scheduling Windows containers in Kubernetes.The Flannel network provider must be used.

Windows support cannot be enabled for existing clusters.

You can only add Windows nodes to a cluster if Windows support is enabled when the cluster is created.

Some other requirements for Windows clusters include: Windows nodes can only be used for deploying workloads. The Kubernetes controlplane can only run on Linux nodes, and the Windows nodes can only have the worker role. In a Windows cluster provisioned with Rancher, the cluster must contain both Linux and Windows nodes.

When provisioning a custom cluster using Rancher, Rancher uses RKE (the Rancher Kubernetes Engine) to install Kubernetes on your existing nodes.
