Note:

Prepare and configure OCI Resource Manager Stack for creating extra nodes on OKE

Introduction

This is part two of a six-part tutorial series that shows you how to deploy a temporary set of resources on an OKE cluster using Golang microservices representing the usage of OCI SDK, OCI-CLI, Resource Manager, OCI Devops and Helm to deploy and destroy Apache Airflow.

Objective

Configure OCI Resource Manager Stack and create a new node pool on the OKE cluster.

Prerequisites

Task 1: Create the OCI Resource Manager stack using OCI-CLI command line

  1. Go to your bastion jump-box console and install git bastion virtual machine jump-box.

    sudo yum install git -y

    T3_4

  2. Get the task1_step_2_package.zip that contains the Terraform files to add new node on OKE and save it on the jump-box host.

    cd $HOME
wget https://docs.us.oracle.com/en/learn/resource-manager-airflow-oke-part2/files/task1_step_2_package.zip
unzip task1_step_2_package.zip

    T1_2

  3. Modify the variables related to your tenant with the variables you have noted.

    • Edit the vars_to_stack.json file and replace the values of each required variable.

      {"compartment_id": "ocid1.compartment.oc1..xxx",
 "region": "sa-saopaulo-1",
 "ssh_public_key": "ssh-rsa AAAxxx",
 "extra_node_pool_subnet": "ocid1.subnet.oc1.sa-saopaulo-1.xxx",
 "oke_cluster_id": "ocid1.cluster.oc1.sa-saopaulo-1.xxx",
 "kubernetes_version": "v1.25.4"
 }

      Important TIP: To avoid parsing errors regarding your ssh-key, you must remove the line break. Run the following command to get your ssh public key:

      cat ~/.ssh/id_rsa.pub | tr '' '\n'

  4. Now run the OCI-CLI command to create the resource manager stack on your tenant. Make sure you replace the compartment id with the one for your tutorial.

    export COMPARTMENT_ID="place_your_compartment_id_here"
oci resource-manager stack create --compartment-id $COMPARTMENT_ID --config-source ./extra_nodes.zip --variables file://vars_to_stack.json --display-name "CLI Extra nodes" --description "New nodes for workload only labeled" --working-directory ""

    • Take note of the id created on your stack manager from the console as shown in the following image.

      T1_2

Your resource manager stack has been created and you’re good to proceed with the next part of this lab.
