To run the latest version of Docker each time you start it, it’s as easy as creating and running this script:
#!/bin/bash OPTS="-d" if [[ -f ~/dockerbin/docker ]] ; then rm docker fi if [[ ! -d ~/dockerbin/ ]] ; then mkdir ~/dockerbin fi wget https://get.docker.io/builds/Linux/x86_64/docker-latest \ -O ~/dockerbin/docker chmod +x ~/dockerbin/docker sudo ~/dockerbin/docker $OPTS &
If you need to add special options (like -g to change the location of the Docker install directory), you can edit the variable at the top of the file.
I don’t recommend using this for production systems, but while Docker is under heavy development, this is an easy way to stay up-to-date and get the bugfixes.
I’m beginning to copy over my technology-related posts from Google+ to this blog, mostly so I have an easy-to-read record of them. This one was originally published on 13 May 2014: Quick Docker Tip
