@aws is a vendor-specific space for declaring your AWS region & profile


  • Accepts values for either or both of two keys:
    • region: AWS region ID of the region you'll deploy this project to
    • profile: name of the profile you prefer to use with this project, as defined in your local AWS profile

For more on working with AWS, please see: Multiple AWS Accounts.

Alternatively, if you want a less granular approach, you can declare your preferred region and profile in your .bashrc (more information here).

If you have AWS exports in your .bashrc and @aws specified in your .arc project, the @aws section will win.


For example, to deploy to the northern California AWS AZ with your AWS work profile's credentials, use:

region us-west-1
profile work

Next: Setup DNS with @domain
