Can I use the EC2 worker pool autoscaler without API credentials?

Last updated: September 8, 2025

Context

When setting up the EC2 worker pool autoscaler, users may want to authenticate using alternative methods such as OIDC instead of using Spacelift's API key and ID credentials.

Answer

No, the EC2 worker pool autoscaler requires Spacelift's API key and ID credentials to function. There are currently no alternative authentication methods available, including OIDC.

To set up the autoscaler, you must provide:

  • Spacelift API Key

  • Spacelift API Key ID

These credentials are essential for the autoscaler to interact with Spacelift's API and manage the EC2 worker pool effectively.
