have jenkins start an EC2 instance and Terminating it

votes

I have a full deployment job that takes an ip of a running instance and deploys my system on it.

I currently hold an EC2 instance for automation tests that run every night, but the instance is expensive and im looking for a way to initiate it before the tests and terminate it after the test.

I looked for EC2 plugins that can help and the closest one was this but this is for making slaves and thats not what I want.

I want to be able to launch an EC2 instance, and pass its IP address to the automation tests job, then terminate that instance once done.

I started making a command line bash file for this, but this seems like too much work, and I thought maybe there is something im missing.

why dont you make jenkins run a shell script and inside that shell script write the command to run EC2 and then another to kill after work is done? - mbn217

Your requirement is valid and amazon knows:

When you stop an instance, we shut it down. We don't charge usage for a stopped instance, or data transfer fees, but we do charge for the storage for any Amazon EBS volumes.

Reference :
- https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/Stop_Start.html

Here some approaches to start/stop your instaces

Amazon EC2 HTTP API

This is an api rest and you can perform a simple http request to start or stop your instance:

https://ec2.amazonaws.com/?Action=StartInstances&...


https://ec2.amazonaws.com/?Action=StopInstances&...

You can invoke this api from Jenkins in many ways : simple shell execution,groovy and scripted/declarative, pipelines.

AWS CLI

Here more about how suspend instances using aws cli:

AWS Instance Scheduler

In 2018, AWS launched the AWS Instance Scheduler, a new and improved scheduling solution that enables customers to schedule Amazon EC2 instances.

With this tool you can automatically start and stop the Amazon EC2 and Amazon RDS instances.

With this approach you don't need Jenkins :b
