为Docker容器自动配置Open Stack VM

Question

Is there a way to automate the provisioning of open stack VM for Docker Containers? For example I have 3 mesos slaves running on 3 open stack vms and now there are no more VM's left. My next docker containers is waiting to be run and I want open stack to know that my docker container needs a VM and it should automatically instantiate a VM. How to go about it? What open source technologies are available to make this work?

Answer 1

As Adam points out this is out of band of Mesos and would require some coding / scripting on your part. You could however use the mesos-master REST API to determine capacity of the cluster. {mesos-master ip}:5050/master/stats.json or {mesos-master ip}:5050/system/stats.json should provide good information

Based on values there, you could automate OpenStack .
