What is Krane?

Krane is very simple parallel executor for Docker™ builder. The tool to build lots of docker images in parallel.

What for?

If you have to build multiple images frequently, and you have powerful dev machine - you can get a significant speedup if you'll build images in parallel.

How it works?

Quite trivial: you provide configuration in YAML format, Krane applies basic dependency analysis, and executes build with respect to graph topology.

How to use?

git cone https://github.com/raver119/krane
cd krane
go build -o krane .

Once you have the binary - write the build configuration in YAML format like this:

build:
  - containerName: organiation/image:latest
    dockerpath: /path/to/Folder
    noCache: false
  - containerName: organiation/other_image:stable
    dockerpath: /path/to/OtherFolder
    noCache: false
threads: 12

Then just run it:

krane -f Path/To/File.yaml

If everything is ok, you'll see something like this:

Successfully built 6 images

Is Minikube supported?

Minikube has no need in any kind of special treatment. Just run eval $(minikube docker-env) before running Krane, and all new images in this session will use Minukube's internal registry.
