Upgrading

These instructions are for upgrading your Docker binary for when you had a custom (non package manager) installation. If you istalled docker using apt-get, use that to upgrade.

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
