Illumina Innovates with Rancher and Kubernetes
This section provides an overview of the architecture options of installing Rancher, describing advantages of each option:
The single-node Kubernetes install is achieved by describing only one node in the cluster.yml when provisioning the Kubernetes cluster with RKE. The single node should have all three roles: etcd, controlplane, and worker. Then Rancher can be installed with Helm on the cluster in the same way that it would be installed on any other cluster.
There are also separate instructions for installing Rancher in an air gap environment or behind an HTTP proxy:
Before installing Rancher, make sure that your nodes fulfill all of the installation requirements.
For the best performance and greater security, we recommend a dedicated Kubernetes cluster for the Rancher management server. Running user workloads on this cluster is not advised. After deploying Rancher, you can create or import clusters for running your workloads.
For more architecture recommendations, refer to this page.
Refer to the Helm chart options for details on installing Rancher on a Kubernetes cluster with other configurations, including:
In the Rancher installation instructions, we recommend using RKE (Rancher Kubernetes Engine) to set up a Kubernetes cluster before installing Rancher on the cluster. RKE has many configuration options for customizing the Kubernetes cluster to suit your specific environment. Please see the RKE Documentation for the full list of options and capabilities.
Refer to the Docker installation docs for details other configurations including:
