helm部署nacos

article 2024/11/10 21:14:44

1.去helm仓库拉取nacos包
https://artifacthub.io/packages/helm/kubegemsapp/nacos?modal=install
在这里插入图片描述

helm repo add kubegemsapp https://charts.kubegems.io/kubegemsapp
helm pull kubegemsapp/nacos
tar -zxvf nacos-0.1.5.tgz
mkdir -p nacos/ci/test

2.修改chart配置文件
注释nacos/values.yaml 与nacos/ci/values.yaml里面的数据库，
在这里插入图片描述

3.将nacos/values.yaml这个文件内容拷贝到nacos/ci/values.yaml,新增的文件里面将单点改为了集群模式，部署三个实例，
cp values.yaml ci/
改动1单点改为集群模式
在这里插入图片描述
改动2由一个实例启动改为三个实例启动

改动3，pvc磁盘改为false（关闭pvc挂载），不关闭就无法启动

这个nacos/ci/values.yaml文件启动的时候加了-f在后面，会默认覆盖前面的配置，只有这个文件里面没有的才会读取前一级的values.yaml

#这个是自己加的参数固定到一台机器上面运行pod，不想在一台机器上启动可以去掉
affinity:
  nodeAffinity:

# This is a YAML-formatted file.

resources:
  # We usually recommend not to specify default resources and to leave this as a conscious
  # choice for the user. This also increases chances charts run on environments with little
  # resources, such as Minikube. If you do want to specify resources, uncomment the following
  # lines, adjust them as necessary, and remove the curly braces after 'resources:'.

    cpu: "1"
    memory: 2.5Gi
  requests:
    cpu: 500m
    memory: 2Gi

tolerations: [ ]

3.增加数据库配置，nacos/ci/test/values.yaml 改成自己的数据库配置，name为数据库名称
values.yaml

nacos:
  storage:
    type: mysql
    db:
      host: percona80-master.devops
      name: nacos
      port: "3306"
      username: nacos
      password: password
      param: characterEncoding=utf8&connectTimeout=60000&socketTimeout=180000&autoReconnect=true&useSSL=false&allowPublicKeyRetrieval=true

启动命令

helm upgrade nacos ./nacos/ -f ./nacos/ci/values.yaml -f ./nacos/ci/test/values.yaml -i -n default

helm list -n default
helm uninstall nacos -n default

查看运行成功
