3. Jenkins 설치

Jenkins 를 설치하고자 하는 Kubernetes 의 Namespace 와 Version 을 설정한 후 설치를 진행한다.

helm install jenkins jenkins/jenkins --version <version> -n <namespace>

Jenkins 가 정상적으로 설치되면 admin Passwrod 를 확인할 수 있는 방법과 포트포워딩을 통해 jenkins 에 접속하는 방법에 대한 설명이 나온다.

NAME: jenkins
LAST DEPLOYED: Tue Mar  7 15:11:52 2023
NAMESPACE: cicd
STATUS: deployed
REVISION: 1
NOTES:
1. Get your 'admin' user password by running:
  kubectl exec --namespace cicd -it svc/jenkins -c jenkins -- /bin/cat /run/secrets/additional/chart-admin-password && echo
1. Get the Jenkins URL to visit by running these commands in the same shell:
  echo http://127.0.0.1:8080
  kubectl --namespace cicd port-forward svc/jenkins 8080:8080

1. Login with the password from step 1 and the username: admin
2. Configure security realm and authorization strategy
3. Use Jenkins Configuration as Code by specifying configScripts in your values.yaml file, see documentation: http://127.0.0.1:8080/configuration-as-code and examples: https://github.com/jenkinsci/configuration-as-code-plugin/tree/master/demos
