# CAPOCI installation
2+
This project includes a simplified procedure to deploy and use Cluster API inside any
3+
OKE cluster.
4+
The only prerequisite is to have an Oracle Cloud tenancy with an OKE cluster already
5+
provisioned and accessible.
6+
7+
1. Create a dynamic group for the OKE cluster. As an example, we will call the
8+
dynamic group my-oke-cluster:
9+
` instance.compartment.id = 'OKE_COMPARTMENT_ID' `
10+
2. Create the following policies:
11+
```
12+
Allow dynamic-group <oke-dynamic-group> to manage instance-family in compartment <compartment name>
13+
Allow dynamic-group <oke-dynamic-group> to manage virtual-network-family in compartment <compartment name>
14+
Allow dynamic-group <oke-dynamic-group> to manage cluster-family in compartment <compartment name>
15+
```
16+
3. Open the Cloud Shell, upload the install.sh script and execute it. Be sure that your
17+
Kubeconfig file is correctly configured and in the right context.
18+
4. To provision another OKE cluster, substitute the variable in oke-capoci.yaml and
19+
apply it to the cluster.
20+
5. See the creation of the OKE cluster and the Node Pool.
21+
22+
NOTE: The cluster deployed here is very simple, but you can actually configure it in
23+
every aspect, you can configure the network and even create Virtual Node clusters!
