6.2. 在 MicroShift 上创建 GitOps 应用程序

流程

1. 创建 YAML 文件并为应用程序添加自定义配置：

   cert-manager 应用程序的 YAML 示例

   kind: AppProject
   apiVersion: argoproj.io/v1alpha1
   metadata:
     name: default
     namespace: openshift-gitops
   spec:
     clusterResourceWhitelist:
     - group: '*'
       kind: '*'
     destinations:
     - namespace: '*'
       server: '*'
     sourceRepos:
     - '*'
   ---
   apiVersion: argoproj.io/v1alpha1
   kind: Application
   metadata:
     name: cert-manager
     namespace: openshift-gitops
   spec:
     destination:
       namespace: cert-manager
       server: https://kubernetes.default.svc
     project: default
     source:
       path: cert-manager
       repoURL: https://github.com/anandf/microshift-install
     syncPolicy:
       automated: {}
       syncOptions:
       - CreateNamespace=true
       - ServerSideApply=true

   spring-petclinic 应用程序的 YAML 示例

   kind: AppProject
   apiVersion: argoproj.io/v1alpha1
   metadata:
     name: default
     namespace: openshift-gitops
   spec:
     clusterResourceWhitelist:
     - group: '*'
       kind: '*'
     destinations:
     - namespace: '*'
       server: '*'
     sourceRepos:
     - '*'
   ---
   kind: Application
   apiVersion: argoproj.io/v1alpha1
   metadata:
     name: spring-petclinic
     namespace: openshift-gitops
   spec:
     destination:
       namespace: spring-petclinic
       server: https://kubernetes.default.svc
     project: default
     source:
       directory:
         recurse: true
       path: app
       repoURL: https://github.com/siamaksade/openshift-gitops-getting-started
     syncPolicy:
       automated: {}
       syncOptions:
       - CreateNamespace=true
       - ServerSideApply=true

2. 要部署 YAML 文件中定义的应用程序，请运行以下命令：

   $ oc apply -f <filename>.yaml
