How to change the default Docker network in CentOS 6

One of the dev teams I used to support has been using Docker for jobs started on Jenkins executors(worker nodes).  The Jenkins worker nodes  have been around for a while  and consequently run CentOS 6 with older docker-io packages installed.

When I was asked to provision some new executors I was at a loss because there is very little documentation for installing docker in CentOS 6.  In fact it’s recommended by Docker not to use the older Linux kernels(2.6.x).

Goals of this post:

  • Install  docker-io on CentOS 6
  • configure daemon options – default network
