I will be used as follows:

e2b template build --image-url-mask=0123456789.dkr.ecr.eu-west-1.amazonaws.com/custom-environments:{buildID}

Okay, I think it's the name that was confusing me - can you maybe change it to

--image-uri

I think mask in the name is very important. There is a variable in it that is resolved during runtime

After discussion with @jakubno we decided that using CLI attribute can be confusing for customers that don't need this image to be used, and can look like we are supporting custom docker repositories for our primary e2b cloud.

There is a new ENV variable called E2B_IMAGE_URI_MASK that does the same work as the previous CLI param.
