Install kind for Jenkins

Pre-requisites : Install docker engine

docker engine 설치는 docker engine 설치 글을 참조해 주세요.

Step 1 : Download kind binary

kind binary를 download 받습니다.

curl -Lo ./kind https://kind.sigs.k8s.io/dl/v0.17.0/kind-linux-amd64
chmod +x ./kind
sudo mv ./kind /usr/local/bin/kind

Step 2 : config 파일 작성성

Kind를 이용하여 Kubernetes Cluster를 생성하기 위해 jenkins-config.yaml 파일을 아래와 같이 작성합니다.

apiVersion: kind.x-k8s.io/v1alpha4
kind: Cluster
nodes:
- role: control-plane
- role: worker
- role: worker

Step 3 : Create Cluster

Cluster를 생성합니다.

kind create cluster --config jenkins-config.yaml

Step 4 : Configure

Kind는 .kube/config파일 변경 없이 인증서 파일의 내용이 config파일에 있어서 변환할 필요는 없습니다.
minikube와 동일하게 Jenkins를 설정합니다.

• Install Kubernetes Plugins
• Manage Jenkins > Manage Nodes and Clouds > Configure Clouds

Step 4 : Kubernetes Dashboard 설치

Kubernetes dashboard yaml파일을 remote에 있는 것을 직접 kubernetes cluster에 적용합니다.

kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.4.0/aio/deploy/recommended.yaml

Step 5 : Kubernetes Dashboard 접속

kubectl proxy로 8001 port를 다음과 같이 오픈합니다.

kubectl port-forward svc/kubernetes-dashboard -n kubernetes-dashboard 443:443 --address 0.0.0.0

브라우저에서 dashboard에 접속합니다.

https://Your-Server-IP/

Step 6 : Token 생성

• kubernetes-dashboard namespace에 admin-user Serviceaccount를 생성

  kubectl create sa admin-user -n kubernetes-dashboard
  

• cluster-admin을 clusterrolebinding합니다.

  kubectl create clusterrolebinding admin --clusterrole cluster-admin --serviceaccount kubernetes-dashboard:admin-user
  

• token을 생성

  kubectl create token admin-user -n kuberneetes-dashboard

생성한 token을 dashboard token 입력항목에 붙여넣기 합니다.
