How to install an older Docker version

These instructions are only tested on installations that use the Docker apt repository.

Remove the existing installation
```
sudo apt-get remove docker-engine
```
List the available versions

	SCALA_HOME=/usr/share/scala

	# NOTE: bash is used by scala/scalac scripts, and it cannot be easily replaced with ash.
	RUN apk add --no-cache --virtual=.build-dependencies wget ca-certificates && \
	apk add --no-cache bash curl jq && \
	cd "/tmp" && \
	wget --no-verbose "https://downloads.typesafe.com/scala/${SCALA_VERSION}/scala-${SCALA_VERSION}.tgz" && \
