A new set of Docker tools

[Posted December 4, 2014 by corbet]

Docker has announced a new set of container management tools: Machine (for system provisioning), Swarm (native clustering for Dockerized applications), and Compose (assembly of multi-container applications). "Finally, Docker Swarm has a pluggable architecture and ships 'batteries included' with a default scheduler. Stay tuned for the public API in the first half of 2015 which will allow swapping-in a scheduler implemented by an ecosystem partner or even your own custom implementation. Nevertheless, regardless of the underlying scheduler implementation, the interface to the app remains consistent, meaning that the app remains 100% portable."

...and you can use docker from within all the major cloud vendors. this seems like a useful first step into providing auto-scaling style features in minority cloud vendors like digital ocean

maybe docker will succeed where openstack seems to have failed...providing meaningful vendor neutrality in the cloud

Docker and OpenStack are far too different.

In the sense that OpenStack is compatible with EC2, you're not locked into Amazon if you use their API's. Just about every large vendor is chasing OpenStack at the moment, and it's quite open. You could argue that cloud technology can create lock in, but OpenStack is only a tool.

but none of the major cloud vendors are offering openstack. you can actually use docker on aws and take your dockerfiles to azure or gce.

its not that ec2 is compatible with openstack, it is the other way around, because aws is not pursuing compatibility with openstack as a goal.

Openstack isn't a virtualization or container technology. It's not even like 'libvirt' or some other container/vm management solution like Ovirt/Vmware/etc.

The best way to think about Openstack is that it's a datacenter operating system. You use it for managing networks, machines, virtual networks, virtual machines, load balancers, administration tools, user permissions for managing/interacting different portions of your datacenter, etc etc. You have identity management services, authentication services, quota sytsems, etc.

Now, of course, it focuses on virtual machines and that sort of thing. ie 'The Cloud'.

Docker and Openstack really are not directly comparible.

That's like saying 'Maybe vim will succeed were hurd has failed'. It doesn't make any sense. They are not trying to solve the same types of problems.

> .providing meaningful vendor neutrality in the cloud

That is making a lot of presumptions about what the goals of openstack are, which I don't think is accurate at all.

I really doubt that anybody working in openstack had any expectation at all that companies like Microsoft or Amazon are going to drop their in-house cloud technology for openstack anytime in the foreseeable future.

May be we should frame the comment on a wall :)
