Deploying Applications on Oracle Cloud Kubernetes

Deploying applications using Oracle Cloud Kubernetes involves several key steps that ensure a smooth and efficient process.

Oracle Cloud Infrastructure Container Engine for Kubernetes (OKE) provides a user-friendly platform for managing Kubernetes clusters and deploying applications seamlessly.

  1. Steps to Create and Manage a Kubernetes Cluster:
    • Sign in to Oracle Cloud Infrastructure Console: This is the first step where you use your cloud tenant name, username, and password.
    • Navigate to Kubernetes Clusters: Under Developer Services, select Kubernetes Clusters.
    • Create a Cluster: Choose ‘Quick Create’ for an automated setup or ‘Custom Create’ for more control.
    • Configure Cluster Settings: Name your cluster, select a compartment, and define node settings.
    • Review and Create: Finalize your cluster settings and create the cluster.
  2. Deploying Sample Applications Using kubectl:
    • Initialize Your Environment: Set up the kubeconfig file for your cluster.
    • Deploy Applications: Use the kubectl command line tool to deploy applications. For example, you can create a deployment using kubectl run and manage it using kubectl get deployments.
    • Expose Applications: Expose your applications externally using Kubernetes services like LoadBalancer or NodePort.
  3. Accessing Clusters Using Kubernetes Command Line and Dashboard:
    • Using kubectl: Confirm the installation of kubectl and connect to your cluster using kubectl get nodes.
    • Kubernetes Dashboard: Deploy the Kubernetes Dashboard and connect to it for a GUI-based cluster management experience.
