Docker Bake is Now Generally Available

Docker announced that Docker Bake is now generally available¹. Docker Bake is an orchestration tool that streamlines Docker builds.

It help developers to transform complex build commands into declarative style configurations, which means from ²

$ docker build \
    -f Dockerfile \
    -t myapp:latest \
    --build-arg foo=bar \
    --no-cache \
    --platform linux/amd64,linux/arm64 \
    .

to

target "myapp" {
  context = "."
  dockerfile = "Dockerfile"
  tags = ["myapp:latest"]
  args = {
    foo = "bar"
  }
  no-cache = true
  platforms = ["linux/amd64", "linux/arm64"]
}

As the new says:

You can write Bake files in HCL, YAML (Docker Compose files), or JSON. In general, HCL is the most expressive and flexible format, which is why you'll see it used in most of the examples in this documentation, and in projects that use Bake.

Well, I may don't think so for the HCL part =.=
