Building docker images

The fissile build command comes with a helpful subcommand for building docker images from a BOSH release.

The command is fissile build release-images. See the docs

How to use it?

The following are the flags that you need to provide, in order to generate assets and building the Docker image.

--stemcell

You need to provide a reference to a docker image, containing the stemcell you want to use, as the underlying layer. For example:
```
--stemcell=splatform/fissile-stemcell-opensuse:42.3-36.g03b4653-30.80
```
Note: You docker stemcell image is required to have two specific labels. They are stemcell-flavor and stemcell-version.
--name

This is the name of the BOSH release. This should be the value defined in the BOSH deployment manifest.
--version

The version of the BOSH release. This should be the value defined in the BOSH deployment manifest.
--sha1 The sha1 of the BOSH release. This should be the value defined in the BOSH deployment manifest.
-url The url of the BOSH release. This should be the value defined in the BOSH deployment manifest.

Additionally you could also just generate assets, without forcing fissile to generate a new Docker image. For this, use the --no-build flag.
