Creating Argo CD applications

Step-by-step instructions to create an Argo CD application in GitOps

Codefresh GitOps & Argo CD applications

Create fully GitOps-compliant Argo CD applications directly from the GitOps Apps dashboard. When you commit the changes, Codefresh generates the application manifest and stores it in Git, ensuring a declarative, versioned, and auditable deployment process.

For example Argo CD applications, see this repo.

Create an Argo CD application

Create a new application from the GitOps Apps dashboard. Define settings in Form mode, or edit the manifest directly in YAML mode, toggling between them as needed.

Before you begin
How to
  1. In the Codefresh UI, from the sidebar, select GitOps Apps.
  2. On the top-right, select Add Application.
  3. In the Add Application panel, add definitions for the application:
    • Application name: Must be unique within the cluster.
    • Runtime: The runtime to associate with the application.
    • YAML filename: The name of the application’s configuration manifest, assigned on commit to Git. By default, the manifest is assigned the application name. Change the name as required.

    NOTE
    The application definitions cannot be changed after you continue to the Configuration settings.

Add Application panel

Add Application panel
  1. Select Next to go to the Configuration tab.
    By default you are in Form mode. You can toggle between the Form and YAML modes as you define the application’s configuration settings. You can edit the YAML manifest.
  2. Define the General settings for the application.

Add Application: Advanced settings

Add Application: Advanced settings
  1. Define the Advanced settings for the application.

Add Application: Advanced settings

Add Application: Advanced settings
  1. To commit all your changes, click Commit.
    The Commit form is displayed with the application’s definition on the left, and the read-only version of the manifest with the configuration settings you defined on the right.
  2. Enter the path to the Git Source to which to commit the application configuration manifest.

Add Application: Commit to Git

Add Application: Commit to Git
  1. Add a commit message and then select Commit on the bottom-right of the panel.

Your application is first committed to Git, and then synced to the cluster which may take a few moments.
