Replace ARGOCD_SERVER with your Argo CD server's URL. Then, provide your Argo CD credentials when prompted.

Verifying the Configuration

After setting the values, you can verify the changes by executing:

kubectl get application my-app -o yaml

This command will display the YAML manifest of the application, showing the updated values.

Handling Secrets with Argo CD

Argo CD allows for mid-air updates, which means you can change the configuration of a running application without having to redeploy it. This is particularly useful when dealing with sensitive data like secrets.

Setting Secret Values

To set or update a secret value, you'll use the same argocd helm set value command. However, you'll need to specify the secret's name using the --secret flag:

argocd helm set value my-app --secret my-secret --value Key=Value

Verifying Secret Updates

To confirm that the secret has been updated, you can use the kubectl describe secret my-secret command.

Remember, it's crucial to monitor your running applications and keep your configurations up-to-date to ensure they behave as expected in your production environment. The argocd helm set value command is a powerful tool in achieving this, offering a seamless way to manage your application's configuration.
