Configuring and Scaling Kubernetes Applications with Oracle Kubernetes Engine (OKE) in OCI

Overview of Kubernetes and its benefits for container orchestration.

Introduction to Oracle Kubernetes Engine (OKE) in OCI.

Creating an OKE Cluster

oci ce cluster create --compartment-id <compartment_OCID> --name "MyCluster" --kubernetes-version <version> --wait-for-state ACTIVE

Managing Node Pools

• Adding Node Pool

oci ce node-pool create --compartment-id <compartment_OCID> --cluster-id <cluster_OCID> --name "MyNodePool" --node-image-name "<image_name>" --node-shape "<shape>" --node-pool-lifecycle-state ACTIVE

Scaling Node Pool:

oci ce node-pool update --node-pool-id <node_pool_OCID> --quantity <new_quantity>

Deploying Applications

Deploying Application with kubectl:

kubectl create deployment my-app --image=<docker_image>

Configuring Ingress and Load Balancing

Creating Ingress Controller:

kubectl apply -f ingress-controller.yaml

Exposing Service with LoadBalancer:

kubectl expose deployment my-app --type=LoadBalancer --port=80 --target-port=8080
