We are trying to create a roadmap for the next year of
'container' development, to be reported to the upcoming kernel
summit. Containers here is a bit of an ambiguous term, so we are
taking it to mean all of:
1. namespaces
2. process containers
3. checkpoint/restart
Naturally we can't actually predict what will and won't be worked on,
let alone what will be going upstream. But the following is a list
of features which it seems reasonable to think might be worked on
next year:
1. completion of ongoing namespaces
pid namespace
net namespace
ro bind mounts
2. continuation with new namespaces
devpts, console, and ttydrivers
user
time
namespace management tools
namespace entering
3. any additional work needed for virtual servers?
i.e. in-kernel keyring usage for cross-usernamespace
permissions, etc
4. task containers functionality
base features
specific containers
poll to see who has plans
5. checkpoint/restart
memory c/r
(there are a few designs and prototypes)
(though this may be ironed out by then)
per-container swapfile?
overall checkpoint strategy
in-kernel vs userspace-driven
overall restart strategy
What more needs to be added to this list?
A list of the people we are currently aware of who are showing interest
in these features follows. What I'd like to know is, from this list, do
some people know what general or specific areas they plan to or want to
work on over the next year?
Stakeholders:
Eric Biederman
google
ibm
kerlabs
openvz
osdl (Masahiko Takahashi?)
vserver
Who is missing from the list?
thanks,
