| ## Install a OCP cluster with ARM64 Arch on Oracle Cloud Infrastructure (OCI) with CCM | ||
|
|
||
| Install an OCP cluster in OCI with Platform External as an option and OCI Cloud Controler Manager. | ||
|
|
||
| ## Prerequisites | ||
|
|
||
| - okd-installer Collection with [OCI dependencies installed](./oci-prerequisites.md): | ||
| - Compartments used to launch the cluster created and exported to variable `${OCI_COMPARTMENT_ID}` | ||
| - DNS Zone place the DNS zone and exported to variable `${OCI_COMPARTMENT_ID_DNS}` | ||
| - Compartment used to store the RHCOS image exported to variable `${OCI_COMPARTMENT_ID_IMAGE}` | ||
|
|
||
| Example: | ||
|
|
||
| ```bash | ||
| cat <<EOF > ~/.oci/env | ||
| # Compartment that the cluster will be installed | ||
| OCI_COMPARTMENT_ID="<CHANGE_ME:ocid1.compartment.oc1.UUID>" | ||
| # Compartment that the DNS Zone is created (based domain) | ||
| OCI_COMPARTMENT_ID_DNS="<CHANGE_ME:ocid1.compartment.oc1.UUID>" | ||
| # Compartment that the OS Image will be created | ||
| OCI_COMPARTMENT_ID_IMAGE="<CHANGE_ME:ocid1.compartment.oc1.UUID>" | ||
| EOF | ||
| source ~/.oci/env | ||
| ``` | ||
|
|
||
| ## Setup with Platform External type and CCM | ||
|
|
||
| Create the vars file for okd-installer collection: | ||
|
|
||
| ```bash | ||
| # MCO patch without revendor (w/o disabling FG) | ||
| CLUSTER_NAME=oci-e414rc2arm1usash1 | ||
| VARS_FILE=./vars-oci-ha_${CLUSTER_NAME}.yaml | ||

||
| ## Install the cluster | ||
|
|
||
| ```bash | ||
| ansible-playbook mtulio.okd_installer.create_all \ | ||
| -e cert_max_retries=30 \ | ||
| -e cert_wait_interval_sec=60 \ | ||
| -e @$VARS_FILE | ||
| ``` | ||
|
|
||
| ### Approve certificates | ||
|
|
||
| Export `KUBECONFIG`: | ||
|
|
||
| ```bash | ||
| export KUBECONFIG=$HOME/.ansible/okd-installer/clusters/${CLUSTER_NAME}/auth/kubeconfig | ||
| ``` | ||
|
|
||
| Check and Approve the certificates: | ||
| ```bash | ||
| oc get csr \ | ||
| -o go-template='{{range .items}}{{if not .status}}{{.metadata.name}}{{"\n"}}{{end}}{{end}}' \ | ||
| | xargs oc adm certificate approve | ||
| ``` | ||
|
|
||
| Check if the nodes joined to the cluster: | ||
|
|
||
| ```bash | ||
| oc get nodes | ||
| ``` | ||
|
|
||
| ## Testing | ||
|
|
||
| Setup the test environment (internal registry, labeling and taint worker node, etc): | ||
|
|
||
| ```bash | ||
| test_node=$(oc get nodes -l node-role.kubernetes.io/worker='' -o jsonpath='{.items[0].metadata.name}') | ||
| oc label node $test_node node-role.kubernetes.io/tests="" | ||
| oc adm taint node $test_node node-role.kubernetes.io/tests="":NoSchedule | ||
| ``` | ||
|
|
||
| Run the tests: | ||
|
|
||
| ```bash | ||
| ./opct run -w &&\ | ||
| ./opct retrieve &&\ | ||
| ./opct report *.tar.gz --save-to /tmp/results --server-skip | ||
| ``` | ||
|
|
||
| ## Destroy the cluster | ||
|
|
||
| ```bash | ||
| ansible-playbook mtulio.okd_installer.destroy_cluster -e @$VARS_FILE | ||
| ``` |
