doctl-apps:tldr:853d6

The command "doctl apps list-deployments ${app_id}" is used in the DigitalOcean command-line interface (CLI) tool, doctl, to retrieve a list of deployments associated with a specific app.

Here's what each part of the command means:

• doctl: This is the command used to run the doctl CLI tool.
• apps: This is a subcommand used to perform actions related to DigitalOcean Apps.
• list-deployments: This further specifies that we want to retrieve a list of deployments.
• ${app_id}: This is a placeholder for the ID of the app you want to fetch deployments for. You would replace ${app_id} with the actual ID of your app.

When you run this command with the correct app ID, it will return a list of deployments associated with the specified app. This can be helpful to track the different versions or instances of your app that have been deployed.
