8.2. Creating GitOps applications on MicroShift

Procedure

1. Create a YAML file and add your customized configurations for the application:

   Example YAML for a spring-petclinic application

   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. To deploy the applications defined in the YAML file, run the following command:

   $ oc apply -f <my_app.yaml>

   Replace <my_app.yaml> with the name of your application YAML.
