We are using AWS Image Builder to create a custom AMI for our EC2 instances. I would like to use this same AMI to run our tests. I see that CircleCI has the ability to “use” a custom AMI, but it appears as if only as an execution platform for Docker. Is this correct? Is there a provision to use a customer AMI as the testing platform itself completely separate and distinct from Docker? I don’t want to build a Docker container if we already have an AMI that does the job.
You would have to take an AMI based environment and install the self-hosted runner software onto it. This would then allow CircleCI jobs to be executed within the AMI based machine.
I do this currently with Ubuntu images that I currently have hosted at home, Scaleway and (work in progress) Amazon.
That sounds like it would work for us. Are there more detailed instructions on how to do this? How do you configure the project to use your own AMI? Where is the self-hosted runner software located and how do you install it? Those types of things.
To be honest it is a lot of work to get started as there is a lot of documentation - most of it written by people who knew what they were doing when they started to write it. The starting point is
The docs do not lay out the steps that clearly as they somewhat start in the centre of the process and then expect you to work backwards, but I would say that the steps are the following (from memory)
The steps I have for Linux are
Install the CircleCLI - This needs an API token Create a namespace - One-time task for the whole account and is linked to a single repository! Create runner on namespace - this generates a long auth token string configure launch-agent-config.yaml with the long auth token setup the systemd agent enable the system agent reboot or start the systems agent
