Destroy instance after completing a certain number of builds about ec2-spot-jenkins-plugin HOT 3 OPEN

Just wondering what is use case behind destroying after some build numbers?

from ec2-spot-jenkins-plugin.

@terma Our team has a need for instances in EC2 that we only want to run one time (because we alter system configuration and install packages inside the instance). We also find that we end up with a mess in /tmp or other directories after lots of jobs run, so it would be nice to stop the instance after a certain number of builds as well.

If there's a better way to destroy our running instance when the job is done, that would work for me, too.

Hi, @major; Cc: @terma

Here's a workaround to add into your Jenkins job's Build: Execute shell:

#!/bin/bash -x

if [ "${BUILD_NUMBER}" -ge "100" ]; then
  INSTANCE_ID=$(wget -q -O - http://169.254.169.254/latest/meta-data/instance-id)
  aws ec2 terminate-instances --instance-ids ${INSTANCE_ID}
fi

• Destroy an instance when it has processed 100 builds (whether it is idle or not) (this does not exist today)
