/meta-data/spot/ not supported anymore

yahavb commented 5 years ago

the daemon set returns 404 as /meta-data/spot/ is not available. I checked thru the EC2 console that Lifecycle is spot Any other ways to get interruption notices? this is what I get when I kubectl exec to the pod that runs the spot-sig.

/ # curl http://169.254.169.254/latest/meta-data/spot

You can subscribe to the Cloudwatch events, I hope they still work.

Hi @yahavb

The EC2 meta-data service returns an HTTP 404 response for http://169.254.169.254/latest/meta-data/spot until the instance is going to be interrupted.

The URLs to be polled are either http://169.254.169.254/latest/meta-data/spot/instance-action (returns the action and timestamp for termination) or http://169.254.169.254/latest/meta-data/spot/termination-time (returns termination timestamp only).

To trigger an interruption, you can use Spot Fleet as per instructions here.
