Go to http://docs.docker.io/en/latest/ and get started with docker.
Have Fun !
NOTE: If you were use http://www.hop5.in repository. Dont worry as the package upgrades are seamless due to the package name being same.

Hey Naresh -- thanks for the post! However, I do have a question -- after installing the 3.13 kernel I did a lxc-checkconfig and noticed that User Namespaces was missing . Is this a problem? If so, any idea how to fix / enable it? Also how about the No Swap Limit support missing? Cheers!
ReplyDeleteHi Steve,
DeleteSome of the features are optional. See http://docs.docker.io/en/latest/installation/kernel/
Use these commands to check your active kernel has the things compiled as module/built-in

ReplyDeleteNo way, when I reboot I continue to have the old kernel "2.6.32-358.2.1.el6.x86_64" :(
ReplyDeletePablo, I assume you have selected the kernel in the grub menu, while booting. That should take care of it.
DeleteThanks!
ReplyDeleteYou are welcome, Pieter.
DeleteHi, i'm trying to setup docker to use my hosts network. I'm a little confused at how this is done. I've tried creating the br0 and giving the the IP address of eth0 and putting statements in eth0 to look for this new device. But it never seems to work right. Any help?
ReplyDeleteAndrew, could you see this detailed blog post ? http://jpetazzo.github.io/2013/10/16/configure-docker-bridge-network/
