Google Kubernetes Engine

표준 클러스터 아키텍처 Compute Engine

Kubernetes on Google Cloud When you run a GKE cluster, you also gain the benefit of advanced cluster management features that Google Cloud provides. These include:

Load balancing for Compute Engine instances Node pools to designate subsets of nodes within a cluster for additional flexibility Automatic scaling of your cluster's node instance count Automatic upgrades for your cluster's node software Node auto-repair to maintain node health and availability Logging and Monitoring with Cloud Monitoring for visibility into your cluster

gcloud auth list

gcloud config list project

gcloud config set compute/zone us-central1-a

gcloud config set compute/zone us-central1-a

2: Create a GKE cluster

클러스터 생성

gcloud container clusters create sdk-gke-cluster

Result

Default change: VPC-native is the default mode during cluster creation for versions greater than 1.21.0-gke.1500. To create advanced routes based clusters, please pass the `--no-enable-ip-alias` flag
Note: Your Pod address range (`--cluster-ipv4-cidr`) can accommodate at most 1008 node(s).

4: Deploy an application to the cluster

hello server 생성

$kubectl create deployment hello-server --image=gcr.io/google-samples/hello-app:1.0

deployment.apps/hello-server created

Service 생성

$kubectl expose deployment hello-server --type=LoadBalancer --port 8080

service/hello-server exposed

$kubectl get service

NAME           TYPE           CLUSTER-IP    EXTERNAL-IP   PORT(S)          AGE

5.Deleting the cluster

$gcloud container clusters delete sdk-gke-cluster

The following clusters will be deleted.
