GKE(Google Kubernetes Engine) APP 배포 실습

[Google Kubernetes Engine](https://cloud.google.com/kubernetes-engine/) [표준 클러스터 아키텍처](https://cloud.google.com/kubernetes-engine/docs/concepts/cluster-architecture) [Compute Engine](https://cloud.google.com/compute) 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).
