rancher-machine-driver-oci

The Oracle Cloud Infrastructure (OCI) Driver for (Rancher) Docker Machine allows Rancher to create and manage Kubernetes clusters on OCI.

Create and configure your cluster's Virtual Cloud Network (VCN)

(Rancher) Docker Machine requires the VCN in which you want to create nodes to:

• allow inbound traffic to port 22 (SSH) to the node subnet.
• allow inbound traffic to port 2376 (Docker) to the node subnet.

In addition to the above ports, RKE has port requires for the different node types detailed here.

Install OCI Node Driver for Rancher

1. From the Rancher Global view, choose Tools > Drivers > Node Drivers > Add Node Driver in the navigation bar.

2. Fill in the URLs of the latest Linux build of the OCI Node Driver as well as the location of its UI component.

Create Cloud Credentials for OCI

1. From your user settings, choose > Cloud Credentials > Add Cloud Credential.

2. Select "Oracle Cloud Infrastructure" from the drop down, and fill in your account credentials (tenancy, user, signing key, etc.).

Provision Kubernetes cluster on OCI

1. From the Global view, choose Clusters > Add Cluster.

2. From the infrastructure providers, choose the Oracle Cloud Infrastructure icon.

3. Fill in a cluster name, and add Node Template(s) for the various node types (etcd, Control Plane, or Worker).

4. After you've created a template(s), you can use it provision a new Kubernetes cluster on OCI.

You can access the cluster after its state is updated to Active.

Optional, integrate with OCI Kubernetes Addons

• OCI Flexvolume Driver (for provisioning Block Volumes)
• OCI Cloud Controller Manager (for provisioning LoadBalancers)
