Expose image to custom executor
With #2885 (closed) we added the MVC for the generic executor, which allows the user to setup their own environment.
We have the image keyword which is usually used to define what Docker image to be used. But this can be easily used for podman or lxc, we need to expose the value of
image to the job so that they are able to pull the right image.
Send the value of
image as an environment variable
CUSTOM_ENV_JOB_IMAGE or something similar.
