google cloud platform gcp how to basic use

• ref : 도커/쿠버네티스를 활용한 컨테이너 개발 실전 입문
• All source used in this folder come from the ref.
• gcloud : https://cloud.google.com/sdk/gcloud/reference
• gsutil : https://cloud.google.com/storage/docs/gsutil/
• gcp cli install: https://cloud.google.com/sdk/docs/install-sdk?hl=ko

Using docker google/cloud-sdk not to install google cloud sdk

$docker run -it --rm --net host -v ~/cloud-workspace/google-gcp-access:/shared:rw google/cloud-sdk:latest /bin/bash

in the shell of docker container

0. auth list

gcloud auth list

1. login

gcloud auth login

2. project create or set configuration

gcloud projects create project-cloud-test --set-as-default

• if not working well, then access to web site and create in the site directly

gcloud config set project project-cloud-test     # project in accountn@googlemail.com
gcloud config set compute/region asia-northeast3     # region 
gcloud config set compute/zone asia-northeast3-a     # zone in that region

3. GKE cluster create

gcloud container clusters create swever-cloud --project=project-cloud-test --cluster-version=1.15.12-gke.2 \
--machine-type=n1-standard-1 \
--num-nodes=1 \
--subnetwork=default

• example output

  NAME LOCATION MASTER_VERSION MASTER_IP MACHINE_TYPE NODE_VERSION NUM_NODES STATUS

  swever-cloud asia-northeast3 1.15.12-gke.2 34.64.158.235 n1-standard-1 1.15.12-gke.2 3 RUNNING

gcloud compute project-info describe --project project-cloud-test

gcloud container clusters describe swever-cloud

4. gcloud로 클러스터를 제어할 수 있도록 kubectl 인증정보를 설정/가져오기

gcloud container clusters get-credentials swever-cloud
==> 확인: 
kubectl get nodes  

• example output root@e1dedd3c0179:/shared# kubectl get nodes

  NAME STATUS ROLES AGE VERSION

  gke-swever-cloud-default-pool-347ceff4-lckr Ready 40m v1.15.12-gke.2

  gke-swever-cloud-default-pool-88f406bb-f3bg Ready 40m v1.15.12-gke.2

  gke-swever-cloud-default-pool-e402882d-0w7p Ready 40m v1.15.12-gke.2

5. 웹 브라우저 대시보드에서 확인할 수 있도록...

   : ref: https://kubernetes.io/ko/docs/tasks/access-application-cluster/web-ui-dashboard/

kubectl apply -f https://raw.githubusercontent.com/kubetm/kubetm.github.io/master/sample/practice/appendix/gcp-kubernetes-dashboard.yaml 
kubectl proxy --port=8001

6. access to http://127.0.0.1:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/#!/overview?namespace=default

Follow the below step if you already have project and cluster

gcloud auth login
gcloud config set project project-cloud-test     # project in accountn@googlemail.com
gcloud config set compute/region asia-northeast3     # region 
gcloud config set compute/zone asia-northeast3-a     # zone in that region
gcloud container clusters get-credentials swever-cloud
kubectl get nodes  

to delete projects after finishing project

gcloud endpoints services delete map.endpoints.project-cloud-test.cloud.goog --project=project-cloud-test
gcloud endpoints services delete www.endpoints.project-cloud-test.cloud.goog --project=project-cloud-test
gcloud projects delete project-cloud-test
 You can undo this operation for a limited period by running the command below.
     $ gcloud projects undelete project-cloud-test
