Enable Argo CD

Install Verrazzano and set up a multicluster environment by following these instructions.
a. Because Argo CD is not enabled by default, you must first enable argoCD on the admin cluster.
b. When you register managed clusters, they are automatically registered in Argo CD.
Access the Argo CD console using the instructions at Access Verrazzano.
After you set up your application in the Argo CD console, those registered clusters will be available for you to select, deploy, and manage applications.

Configure repositories

In the Argo CD console, configure repositories that will contain the Kubernetes resources for deploying an application.

The following is a sample procedure to configure a private Git repository through HTTPS.

Log in to the Argo CD console.
In the left navigation, click Settings.
Click Repositories.
Click Connect Repo.
Select VIA HTTPS as the connection method.
For Project, specify default.
NOTE: Unless they are grouped together, all the projects are defined in the default level.
For Repository URL, provide the required URL.
If it is a private repository and a user name and password is required to connect to the repository, enter the required credentials.
NOTE: The other fields are optional and based on how the Git repository is configured.
Click Connect and verify that the connection status displayed is Successful.

Docs: Deploy Applications with Argo CD

Mon, 01 Jan 0001 00:00:00 +0000

To deploy applications in a custom namespace, create Argo CD applications that specify the Git repository path, which Argo CD requires to synchronize and deploy the applications in the specified namespace.

NOTE: You can either pre-create a namespace and label it or auto-create a namespace when deploying an application.

This example provides information about how to deploy the Hello-helidon application. The Hello-helidon application and component YAML files are available at Hello World Helidon.

Log in to the Argo CD console.
Click New App.
Specify a name for the application.
For Project Name, select default.
Select the required Sync Policy option:
- Automatic - By default, every three minutes, Argo CD checks the specified Git repository and synchronizes the updates in Kubernetes to the Git repository.
- Manual - For manually synchronizing the updates to the Git repository, use the Manual option.
If you want to auto-create a namespace, in the Sync Options section, select Auto-Create Namespace.
By auto-creating the namespace, the application will be deployed outside of the service mesh. The best practice is to pre-create the namespace and label it.
Under the Source section, enter the following:
- Repository URL: https://github.com/verrazzano/verrazzano/
- Revision: master
- Path: Path in the repository where the Kubernetes resource definitions are listed. For example: examples/helidon-config
Under the Destination section, do the following:
- Cluster URL: Select the cluster to which you want to deploy the applications.
- Namespace: Specify the namespace in which you want to deploy the applications. The instructions in this sample use hello-helidon as the namespace.
Click Create.
If you selected Manual as the Sync Policy option, then click Sync. In the Synchronize Resources section, select all the resources, and then click Synchronize.
This creates the Argo CD application and a pictorial representation of the deployed applications is displayed.

To verify or undeploy the Argo CD application, see Verify the deployed application and Undeploy applications.
