Wow, docker image with DEY 3.2 + Toolchain is 10GB!

Hi…we’re trying to compile our application in a Docker container. We created an image using the digidotcom/dey:dey-3.2-r3 as a base and then added the ConnectCore8x toolchain. Building the app works fine. But, my question is, is there anyway to shrink the size of the new Docker image? The digidotcom/dey:dey-3.2-r3 image by itself is 1.3GB but after adding the toolchain, the image is 10GB!! We’ll be hosting our build server on AWS which will require us to download our 10GB image every time we do a build. I’d prefer not to continually download 10GB. Any suggestions on shrinking the image would be appreciated! Thanks in advance.
