Re: Mesos Calico CNI

2016-05-20 Thread Qian Zhang
the quickest way to try CNI network support in Mesos from E2E is: start a Mesos master and a Mesos agent with CNI isolator/some CNI network configs/some CNI plugins loaded, and run "mesos-executor" to launch a container to join one CNI network. Thanks, Qian Zhang On Wed, May 18,
