AWS Docker Autoscaler: error with Docker Autoscaler Executor and EC2 Instance Connect #1200
Description
I am encountering an occasional issue while using the Docker Autoscaler executor. Sometimes, the following errors are logged, indicating problems with EC2 Instance Connect and the state of the EC2 instance:
Preparing the "docker-autoscaler" executor

EC2 Instance Connect is not supported on a terminated instance. (docker.go:779:0s)
Will be retried in 3s ...

The issue occurs occasionally, and re-running the job typically resolves it.
