Show container build output during ddev start?

[deviantintegral]

Is there a way we can get docker-compose build output to show while a container is building? While it shows if there's an error, it can be confusing if a container simply has a larger set of additions on top of it, or if something in the build process is hanging like a bad network connection.

Locally, I work around this when developing by running ddev debug compose-config > .ddev/.ddev-docker-compose-full.yaml and then ~/.ddev/bin/docker-compose -f .ddev/.ddev-docker-compose-full.yaml build web --progress=plain, but that doesn't help in the "something is unexpectedly slow" situation, or CI where tailing verbose logs live is more helpful.

I would like this also. I have to do as you did from time to time.

ddev debug refresh currently does this stuff, but I'd like it if it would do a build stage separately with full output. ddev debug refresh -v for example.

ddev/cmd/ddev/cmd/debug-refresh.go

Lines 42 to 54 in bbb2cac

	util.Debug("Executing docker-compose -f %s build --no-cache", app.DockerComposeFullRenderedYAMLPath())
	_, _, err = dockerutil.ComposeCmd([]string{app.DockerComposeFullRenderedYAMLPath()}, "build", "--no-cache")
	if err != nil {
	util.Failed("Failed to execute docker-compose -f %s build --no-cache: %v", err)
	}
	err = app.Restart()
	if err != nil {
	util.Failed("Failed to restart project: %v", err)
	}
	util.Success("Refreshed docker cache for project %s", app.Name)
	},

Thanks for exploring this territory; a PR would be welcome, but I imagine we'll get to it at some point.

It's also possible that ddev start could have a 2-stage start with build and then up, and capture the build stuff with -v or something.

A ddev build would be really good. That way, I could be building containers while leaving existing ones running. As well, it would be one step closer to being able to push up customized web container images to a registry to save on installation time.
