create-stack: stream output from Docker

[robdimsdale]

Currently when running jam create-stack it appears to hang while building the images:

Building io.buildpacks.stacks.jammy.full
  Building on linux/amd64
    Building base images

In the case of the full stack, this process can take many minutes.

When running a docker build command, there is constant streaming output.

It would be a significant UX improvement to jam create-stack if we could stream this same output (or similar) while we build the stack.

Is this a dupe of #70 or is there a difference there that I'm missing?

[robdimsdale]

I view them as different. I would expect to stream the docker output regardless of verbose mode. I view the --verbose flag as a more general debugging that would include output that indicates steps taken by jam as well as the docker output.

[ryanmoran]

Can you provide some more detail on that other issue? I don't understand what else gets output if the command always prints its current output and then also always streams the output from the docker build.

Similar to #70, I'm going to close this issue. If there's feedback that stack creators would significantly benefit from streaming docker logs in real-time we can re-open and re-evaluate.
