Synchronize Argo CD Application

In the following guide, we are going to create a self-service action in Port that executes a GitHub workflow to sync an argo cd application. With this, you can manage your Argo CD Application without leaving Port.

Prerequisites

Port's GitHub app needs to be installed.
In your GitHub repository, go to Settings > Secrets and add the following secrets:
- ARGOCD_TOKEN - Argo CD token learn more.
- ARGOCD_APPLICATION_HOST - The host URL of your deployed Argo CD instance. For example, my-argocd-app.com.
- PORT_CLIENT_ID - Your port client id How to get the credentials.
- PORT_CLIENT_SECRET - Your port client secret How to get the credentials.
Optional - Install Port's Argo CD integration learn more

Argo CD Integration

This step is not required for this example, but it will create all the blueprint boilerplate for you, and also ingest and update the catalog in real time with your Argo CD Applications.

In Case you decided not to install the Argo CD integration, you will need to create a blueprint for the Argo CD Application in Port.

Create a workflow file under .github/workflows/sync-argocd-app.yaml with the following content:

tip

We recommend creating a dedicated repository for the workflows that are used by Port actions.

      port_context:

Modification Required

Make sure to replace <GITHUB_ORG> and <GITHUB_REPO> with your GitHub organization and repository names respectively.

            "jqQuery": ".entity.title"
          }
        }
      },
      "required": [
        "application_name"
      ],
      "order": [
        "application_name"
      ]
    },
    "blueprintIdentifier": "argocdApplication"
  },
  "invocationMethod": {
    "type": "GITHUB",
    "org": "<GITHUB_ORG>",
    "repo": "<GITHUB_REPO>",
    "workflow": "sync-argocd-app.yaml",
    "workflowInputs": {
      "application_name": "{{.inputs.\"application_name\"}}",
      "port_context": {
        "entity": "{{.entity.identifier}}",
        "blueprint": "{{.action.blueprint}}",
        "runId": "{{.run.id}}"
      }
    },
    "reportWorkflowStatus": true
  },
  "requiredApproval": false,
  "publish": true
}

Now you should see the Sync Argo CD Application action in the self-service page. 🎉

Let's test it!

Head to the Self Service hub
Click on the Sync Argo CD Application action
Choose the Argo CD Application you want to synchronize (In case you didn't install the Argo CD integration, it means you don't have any Argo CD application in Port yet, so you will need to create one manually in Port to test this action)
Select the application you want to sync. The application_name field should auto-fill after this, if not, manually enter the application name.
Click on Execute
Done! wait for the application to be synchronized.

Congrats 🎉 You've successfully synchronized your Argo CD Application in Port 🔥
