helm 部署使用记录-CFANZ编程社区

0.概念：Helm作为一个包管理工具, 它把Kubernetes资源(比如deployments、services或 ingress等) 打包到一个chart中，方便我们将其chart保存到chart仓库用来存储和分享

1.服务端安装：

curl https://raw.githubusercontent.com/kubernetes/helm/master/scripts/get > get_helm.sh
chmod 700 get_helm.sh
./get_helm.sh

2.客户端安装

wget https://storage.googleapis.com/kubernetes-helm/helm-v2.10.0-linux-amd64.tar.gz
 tar -zxf helm-v2.10.0-linux-amd64.tar.gz
 mv linux-amd64/helm /usr/local/bin/

3.使用记录

[root@pserver78 site2powerone]# helm list  #列出所有kubernetes部署
interested-chipmunk default 
 helm delete  interested-chipmunk  --purge # 删除部署

3.3 创建新的chart

helm create site3powerone

3.4 cat values.yaml

[root@pserver78 site2powerone]# cat values.yaml |egrep -v '#|^$'
replicaCount: 1
image:
  repository: harbor.abc.com/pub/poweronesite
  tag: end
  pullPolicy: IfNotPresent
service:
  type: ClusterIP
  port: 80
ingress:
  enabled: false
  annotations: {}
  path: /
  hosts:
    - site2powerone.mz.abc.com
  tls: []
resources: {}
nodeSelector: {}
tolerations: []
affinity: {}
