Link Your Cloud Provider
Gallery supports first-class integrations with multiple cloud providers, specifically AWS, GCP, and Heroku. The mechanics and reasoning behind the implementation of each of these integrations is covered in more detailed in the relevant sections of the documentation, but the basics of linking each of them are similar. Find the integrations tab, and click "Connect' on the relevant provider.
The integrations tab
Depending on the provider, you will either have to enter an API key/API secret (Heroku and AWS), or use OAuth to authenticate with the provider (GCP). For more information on best practices, and the permissions Gallery will use with each provider, see the relevant section of the documentation for a more detailed discussion.
