AWS App Runner "Create Failed" on health check

I'm creating my first app on AWS App Runner. I have a simple nginx Docker image that works locally by serving html on localhost:8080.

When I try to deploy it, the result is "Create Failed". Upon digging into the CloudWatch logs, I see that the health check failed. The health check is configured to ping the root of the service "/" at port 8080.

Solution

  • I was able to resolve this by deleting my App Runner app (this is currently the only way to change the configuration-- see this issue), then creating a new one and specifying the health check to ping port 80.
