Docker 1.5 is out and it’s time to upgrade and check out the new features. Lets get the upgrade or install out of the way before we look at the new features. To upgrade, this is what I did on my Ubuntu 14.04 desktop, first make sure you do not have any containers running, shut them down safely, then do the following,
sudo apt-get update sudo apt-get remove --purge lxc-docker #Only do this is you have docker installed already. sudo apt-get autoremove --purge #Only do this if ypsou have docker install all ready. sudo apt-get install lxc-docker #This will install docker
Now we have a working docker installed, lets do a quick check to make sure it is OK and working,
sudo service docker statusThis will return the process number if docker is running, if not you will need to start docker 'service docker start', make sure their is no errors. sudo docker version This will return the version of docker
We now good to go.................
Check out the following link from the guys at Docker, http://blog.docker.com/2015/02/docker-1-5-ipv6-support-read-only-containers-stats-named-dockerfiles-and-more/
Lest have a quick look and see what is new that I find good and useful,
- IPv6 support, much needed, good to see.
- Read only containers.
- Stats, O…. this is very nice, you can see resources live cpu, memory, block, networking info about you container from the CLI or API.
- Specify a docker file to use during build.
Nice one docker team……………
