Rohit Yadav commented on CLOUDSTACK-8205:
-----------------------------------------
The idea is to support Docker in ACS, much like LXC since they are similar
(containers). This of course would have some limitations wrt supporting various
network models and disk operations such as taking snapshot and migrations
across hosts.
((Btw, you may also consider supporting Bhyve (VMM from FreeBSD community) in
CloudStack using libvirt which is another interesting project.))
Irrespective of what base OS (RancherOS, CoreOS or Atomic etc) will be, assume
it will be at least Linux 3.16. Assume using barebone technologies instead of
relying on other orchestration or high level systems to control Docker images
unless what you're willing to use are stable enough.
While it's an open discussion on what the scope or the best way to do it; IMO,
the basic things I'm looking for are:
- Support Basic networking (supporting at least Linux bridge or maybe OVS - I'm
not sure the best way to do it)
- SystemVMs can be Docker based or VMs running on KVM
- Local or NFS based shared storage. Support basic operations such as -
upload/register template, create VMs using template.
- Console proxy support (if possible).
Since most players in the docker arena are still figuring out best way to deal
with networking and storage, the expectation of the work is limited to
producing an experimental hypervisor plugin.
For implementation details, read CloudStack 101 on the wiki, see how plugins
are written and follow the LXC plugin implementation or see this commit:
https://github.com/apache/cloudstack/commit/c27c69438ba23386bac7ae4dd651b1d809811157
To proceed, figure out basics of CloudStack - how to build, test, run and use.
Research on this project/idea, learn things just enough so you understand.
Create a plan on how you would do a GSoC project on this. Mentors would love to
see:
1. A detailed proposal - What needs to be done, Scope of the work, Goals
2. Specification, Design, Diagrams. A functional spec on wiki perhaps.
3. A plan or timetable of deliverable, let's say you share your targets for
every week for a 3 month period. This makes it easier for mentors to evaluate
and keep check on progress.
4. Use your imagination!
