#Creating Argo CD Application via web console

Streamline application distribution through visual management interfaces.

#Procedure

1. Container Platform, and navigate to GitOps Applications.

2. Click on Create GitOps Application.

3. Configure parameters in Basic Info and Code Repository sections:

4. Configure parameters in Destination sections:

   • Application: Differential configs don't modify base files in source directory.

   • ApplicationSet: Multi-cluster deployment with Differentiated Configuration.

   Note: Differentiated Configuration don't modify base files in Source Directory.

5. Sync Policy (3-minute reconciliation interval).

   Parameter	Description
   Manually Sync	Requires user confirmation when drift detected.
   Automatic Sync	Automatic reconciliation without human intervention.
   Sync Ignore Configuration	Configure using built-in/custom ignore templates, you can View Sync Ignore Configuration Fields in YAML File. Note: Custom templates require admin configuration.
