计算巢如何使用FluxCD在ACK部署Helm Chart

计算巢支持使用FluxCD在ACK部署Helm Chart,本文介绍如何使用FluxCD在计算巢中进行Helm Chart的部署。

背景信息

计算巢对FluxCD进行部署Helm Chart的过程进行了封装,封装成了ROS公共模块MODULE::ACS::ComputeNest::FluxOciHelmDeploy,MODULE::ACS::ComputeNest::FluxOciHelmDeploy模块支持如下参数。3.png

使用方法

HelmChartUrl支持传入OCI格式的Chart仓库地址,具体在计算巢的使用中,可以选择使用计算巢Helm Chart部署物,也可以使用用户自己的Chart仓库,下面分别进行介绍。

使用Helm Chart部署物创建服务

使用Helm Chart部署物时,先要进行部署物上传。详细信息,请参见创建部署物

  1. 登录计算巢控制台

  2. 在左侧导航栏中,选择我的服务,在我的服务页面中,选择我创建的服务,然后单击创建新服务

  3. 创建新服务界面,配置服务信息。

    此处只列举使用Helm Chart部署物创建服务需要特别配置的内容。更多信息,请参见创建私有部署服务

    1. 模板内容中定义Helm Chart部署物关联的标识位,模板内容的详细信息,请参见服务模板示例

      计算巢提供了{{ computenest::helmchart::xx }}{{ computenest::helm::dockerconfigjson }}两个伪参数,分别用来在模板中关联Helm Chart部署物和拉取密钥,并在部署时进行替换。

      • {{ computenest::helmchart::xx }}:Helm部署物占位符,替换成Helm Chart的完整地址。例如:oci://compute-nest-chart-registry.cn-hangzhou.cr.aliyuncs.com/15634578xxxxxxxx/wordpress:15.4.1。

      • {{ computenest::helm::dockerconfigjson }}:拉取Helm Chart仓库的密钥。

      服务模板伪参数信息如下:

      Resources:
        FluxHelmDeploy:
          Type: MODULE::ACS::ComputeNest::FluxOciHelmDeploy
          Version: v1
          Properties:
            ClusterId:
              Ref: ClusterId
            ReleaseName: wordpress
            Namespace: wordpress
            HelmChartUrl: '{{ computenest::helmchart::test }}'
            DockerConfigJson: '{{ computenest::helm::dockerconfigjson }}'
            ChartValues:
              mariadb:
                primary:
                  persistence:
                    enabled: true
                    storageClass: alicloud-disk-essd
                    size: 20Gi
              persistence:
                enabled: false
    2. 部署物关联处,设置Helm关联信息。

  4. 单击创建服务

使用用户提供的Chart仓库

  1. 登录计算巢控制台

  2. 在左侧导航栏中,选择我的服务,在我的服务页面中,选择我发布的服务,然后单击创建新服务

  3. 创建新服务界面,配置服务信息。

    此处只列举使用用户提供的Helm仓库创建服务需要特别配置的内容。更多信息,请参见创建私有部署服务

    模板内容处,填写使用用户提供的Chart仓库,编写模板内容。

    对于本身就有Chart仓库的用户,可以直接使用自己的Chart仓库,可以是公开仓库,也可以是私有仓库。

    • 使用用户提供的公开Chart仓库的示例如下:

      WordpressComputenestHelmApplication:
        Type: MODULE::ACS::ComputeNest::FluxOciHelmDeploy
        Version: v1
        Properties:
          ClusterId: ClusterId
          HelmChartUrl: oci://registry-1.docker.io/bitnamicharts/wordpress:15.4.1
          ChartValues:
            mariadb:
              primary:
                persistence:
                  enabled: true
                  storageClass: alicloud-disk-essd
                  size: 100Gi
            persistence:
              enabled: false
            wordpressUsername:
              Ref: WordpressUsername
            wordpressPassword:
              Ref: WordpressPassword
          Namespace:
            Ref: 'ALIYUN::StackName'
          ReleaseName: wordpress
    • 当提供的Chart仓库为私有仓库时,DockerConfigJson需要填写Chart仓库的拉取密钥,生成Chart仓库拉取密钥的方式如下。

      kubectl create secret docker-registry SECRET_NAME \
       --docker-server=SERVER_NAME \
       --docker-username=USER_NAME \
       --docker-password=Password
      kubectl get secret SECRET_NAME -o yaml

本示例为WordPress服务以Helm Chart方式部署到ACK上的服务模板。
