I understand why we you would like to do this, however I see Docker as a ‘workload’. It is easy to setup in a VM or bare metal. The Docker ecosystem is booming and there are a ton of Docker “orchestrator” being worked on. It seems to me it will be very difficult to keep up development of a proper docker management service in CloudStack. Personally, I’d rather see us put efforts in properly supporting all the new Docker customized OS (making cloudstack templates for them), fixing our cloudinit support and extending our API to create clusters of machines. That way it will be easy for CloudStack users to start a Docker cluster and use their docker container orchestrator of choice. Very much like if you want to deploy Mesos or the like in CloudStack, Docker orchestrators are really workloads in our clouds. Our strategy for Docker support should be to make it extremely easy for folks to use Docker in CloudStack VMs. Do things like Docker machine support, Docker swarm support etc….and if we want a tighter integration we should look at the AWS ECS API and the GCE container engine API and extend our EC2/GCE bridges to support them. my 2 cts. > > On Monday 16 March 2015 02:53 AM, Diwas Joshi wrote: >> hello, I would like to work on the following issue for >> https://issues.apache.org/jira/browse/CLOUDSTACK-8205 for google summer of >> code 2015.
