Feature request: ability to customise Root volume size of Instance's storage #16

Closed yuravk closed 5 months ago

yuravk commented 5 months ago

Is there a possibility to implement overriding of Root volume size taken from AMI ?

As usual AMIs are configured with as less as possible storage. And that will be grate to have an ability to extend the storage for Instance, and so make self-hosted runner able to run disk size consuming tasks.

Hi, It's a bit tricky with the disk resize/grow on startup but definitely doable. I am looking into it and will keep you posted.

Based on what I could find, our only option would be using an EBS volume mounted at the root disk location. Then using the startup (user-data) script to resize/grow the disk to use the new added storage capacity.

I just need to figure out a few more details first then try and give it a go. 1- How to accurately determine the root disk mount location (some AMIs use /dev/xvda while others use /dev/sda1) 2- Make sure EBS volumes are ephemeral and deleted after each execution 3- Verify that the disk resize can be done fast enough so that registration TTLs don't expire.

Added support for specifying root volume size and storage class.

Released v1.5 with the new feature. https://github.com/NextChapterSoftware/ec2-action-builder/releases/tag/v1.5

I hope this helps.
