How to set different environment variables for each instance?

Hello,

I’d like to run multiple instances of my service, and each instance needs different environment variables (for example, unique API keys). Is there a simple way to give each instance its own set of environment variables?

Thanks in advance!

Hello,

We don't provide a way to give specific instances specific variables at this time.

Best,

If specific variables per instance is not supported, how can we assign unique, persistent numeric IDs (0-1023) to instances in an autoscaling group that:

remain consistent across container restarts
are exposed as environment variables (e.g., INSTANCE_ID)
Change only when a new instance is provisioned

Our distributed ID generator requires this for collision-free operation. Do you have a built-in solution ?
