I was looking at the “8. Using a Lorax Composer Image for Provisioning” section. It says: “You can use this image for bare metal provisioning and provisioning using a compute resource”
Is it possible to use this method with the AWS, Azure, and GCP compute resources?
Well foreman plugins do not support uploading of images, they are simple “launchers”. You can, however, build your images on the foreman server (using lorax, composer, what have you) and then upload them into your account, then use them. But you need to write your own scripts for that and run them manually (e.g. every night from cron etc).
