Red Hat build of MicroShift

Create GitOps applications on MicroShift

You can create a custom configuration by using a YAML file to deploy and manage applications in your MicroShift service after you install the Red Hat OpenShift GitOps Argo CD manifests from an RPM package.

Prerequisites

You installed the microshift-gitops packages.
The Argo CD pods are running in the openshift-gitops namespace.

Procedure

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

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.

Verification

To verify your application is deployed and synced, run the following command:
```
$ oc get applications -A
```
Wait a few minutes for the application to show a Healthy status.
Example output
```
NAMESPACE          NAME               SYNC STATUS   HEALTH STATUS
openshift-gitops   spring-petclinic   Synced        Healthy
```
