- .. _upgrading:
- Upgrading
- ============
- We assume you are upgrading from within the operating system which runs your docker daemon.
- Get the latest docker binary:
- ::
- wget http://get.docker.io/builds/$(uname -s)/$(uname -m)/docker-master.tgz
- Unpack it to your current dir
- ::
- tar -xf docker-master.tgz
- Stop your current daemon. How you stop your daemon depends on how you started it.
- - If you started the daemon manually (``sudo docker -d``), you can just kill the process: ``killall docker``
- - If the process was started using upstart (the ubuntu startup daemon), you may need to use that to stop it
- Start docker in daemon mode (-d) and disconnect (&) starting ./docker will start the version in your current dir rather
- than the one in your PATH.
- Now start the daemon
- ::
- sudo ./docker -d &
- Alternatively you can replace the docker binary in ``/usr/local/bin``
