In this 3 part blog series I am going to share how to get started with Oracle Database 23c Free Developer release on the Oracle Cloud Infrastructure (OCI) using Oracle Container Engine for Kubernetes (OKE) and the Portworx Essentials forever free edition.
In Part 1 will cover the creation of the OKE Cluster, Part 2 will detail the Portworx installation, and Part 3 Oracle 23c Free Developer Release.
Create an Kubernetes Cluster
To create our Kubernetes Cluster let’s logon to the Oracle Cloud using your OCI credentials, navigate to Developer Services, and from there select Kubernetes Clusters (OKE).
Select the required compartment and click on Create cluster.
For the purposes of this blog I will select the Quick create option from the OKE wizard.
Update Cluster Name, Compartment, Kubernetes version, Kubernetes API endpoint, Node type, Kubernetes worker nodes, Shape and image as required.
Check the Portworx supported Managed Kubernetes version and prerequisites, for this blog I updated Name, Kubernetes version to v1.25.4.
and set the number of OCPUs to 8 and the amount of memory to 16GB.
Click Next, then Create cluster, the Cluster will take several minutes to create.
Once Active, click on the Cluster Name. and select Access Cluster.
Choose the method of Access and follow the instructions provided to set-up Kubeconfig.
Using the Local Access steps I can now access the Cluster from my laptop, we can see our Kubernetes Cluster and confirm the number of Worker Nodes, OCI Region, Availability Domains and Fault Domain using kubectl get nodes, providing the topology labels, for example
rekins@rekins--MacBookPro15 ~ % kubectl get nodes -L topology.kubernetes.io/region,topology.kubernetes.io/zone,oci.oraclecloud.com/fault-domain NAME STATUS ROLES AGE VERSION REGION ZONE FAULT-DOMAIN 10.0.10.148 Ready node 33m v1.25.4 uk-london-1 UK-LONDON-1-AD-1 FAULT-DOMAIN-3 10.0.10.53 Ready node 33m v1.25.4 uk-london-1 UK-LONDON-1-AD-3 FAULT-DOMAIN-1 10.0.10.86 Ready node 33m v1.25.4 uk-london-1 UK-LONDON-1-AD-2 FAULT-DOMAIN-2
And list available Kubernetes Storage Classes
rekins@rekins--MacBookPro15 ~ % kubectl get sc NAME PROVISIONER RECLAIMPOLICY VOLUMEBINDINGMODE ALLOWVOLUMEEXPANSION AGE oci oracle.com/oci Delete Immediate false 40m oci-bv (default) blockvolume.csi.oraclecloud.com Delete WaitForFirstConsumer true 40m
Summary
In this blog I have shared to create an 3 node OKE Kubernetes Cluster in an OCI Region, spread across 3 Availability Domains.
In Part 2 we will share how to install Portworx into our new 3 node Kubernetes Cluster.
