一、安装 jenkins

helm repo add jenkinsci https://charts.jenkins.io
helm repo update
kubectl create ns jenkins
helm upgrade --install jenkins jenkinsci/jenkins -n jenkins --create-namespace -f values.yaml

# # =================================================================================================
# # 自定义配置
# # =================================================================================================
# # 1. 修改需要安装的插件
# #    这里额外增加了 ws-cleanup 和中文语言包
# controller:
#   installPlugins:
#     - kubernetes:3937.vd7b_82db_e347b_
#     - workflow-aggregator:596.v8c21c963d92d
#     - git:5.1.0
#     - ws-cleanup:0.45
#     - localization-zh-cn:1.0.24
#     - configuration-as-code:1647.ve39ca_b_829b_42
# # ---------------------------------------------------------------------------
# # 2. 修改默认密码
# controller:
#   adminPassword: "123321"
# # ---------------------------------------------------------------------------
# # 3. 修改执行并发数
# controller:
#   numExecutors: 10
# # ---------------------------------------------------------------------------
# # 4. 开启 NodePort 方式访问
# controller:
#   serviceType: NodePort
