instance re-launch after termination

Hi All,

Thanks for your answers. unfortunately, in the "Auto Scaling Groups" page, I have no option as mentioned in the documentation (see first pic below)- only the option to create new auto scaling group, and I don't have any load balancers (second pic below). I also checked my spot instances, and made sure that I don't have any requests (third pic).

What else could it be? Thanks Again, Adi

Check the tags on your instance, are there any that start with aws:? Those would be created by an AWS service and might show what service is maintaining the capacity.

Alternatively, around the time the replacement instance is launched, look in CloudTrail and filter by:

• EventName: RunInstances
• EventName: CreateFleet

These are generally the 2 API calls used to create new EC2 instances, and it should say which service is making the API call

Hi Shahad_C,

The Tags tab can be found above:

Moreover, it seems that the usage operation is RunIntances.

what should I do next?

Hi

As you mentioned the autoscaling is causing that ,

Try to disable autoscaling attached to your load balancer

This is feasible in console ec2 > load balancer

You can look at this document - https://docs.aws.amazon.com/autoscaling/ec2/userguide/as-enable-disable-scaling-policy.html

Look at the section "To disable a scaling policy (console)"

Other than autoscaling, it could be a spot instance. If you have active spot request, it will launch another instance as well.
