How to install an older Docker version

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

1. Remove the existing installation

   sudo apt-get remove docker-engine

2. List the available versions

   sudo apt-cache showpkg docker-engine
   
   ...
   
   Provides:
   1.11.1-0~jessie -
   1.11.0-0~jessie -
   1.10.3-0~jessie -
   1.10.2-0~jessie -
   1.10.1-0~jessie -
   1.10.0-0~jessie -
   1.9.1-0~jessie -
   1.9.0-0~jessie -
   1.8.3-0~jessie -
   1.8.2-0~jessie -
   1.8.1-0~jessie -
   1.8.0-0~jessie -
   1.7.1-0~jessie -
   1.7.0-0~jessie -
   1.6.2-0~jessie -
   1.6.1-0~jessie -
   1.6.0-0~jessie -
   1.5.0-0~jessie -

3. Install an available version, in this case 1.9.1

   sudo apt-get install docker-engine=1.9.1-0~jessie

4. Verify the install

   docker version

Nothing is ever lost on the internet. A search for an old docker-engine debian package name (docker-engine_1.9.1-0-jessie_amd64.deb) has turned up a mirror.
