the key resource is configuable for cc 3.0?
by Zhi Yong Wu
HI
-m 256M,slots=2,maxmem=512M -smp 24,cores=24,threads=1,sockets=1
Can the count of cores or memory be configurable? The cores seems to be too large.

Unable to bring up Kubernetes master
by Li, Horace
Hi, All,
I was following up the Wiki guidance, https://github.com/01org/cc-oci-runtime/wiki/Clear-Containers-and-Kubernetes, to setup Clear Container 2.1.4 with Kubernetes 1.6.3, and stuck to the step of bringing up Kubernetes master. When executing `#sudo ~/k8s-bring-up.sh`, it stops at "waiting for the control panel to become ready".
What might be the cause of the issue?
Full log is as below,
horaceli@horaceli-workstation:~$ sudo ~/k8s-bring-up.sh

any guide for CC 2.1 + OVS?
by Zhi Yong Wu
HI,
Does anyone have any guide for cc 2.1 + OVS, not ovs-dpdk? If yes, it will be appreciated, thanks. When i am trying to play with cc 2.1 + OVS, i find that the network is not available for 2 cc dockers.

Clear Containers 3.0 owners and tech lead
by Samuel Ortiz
All,
I sent a few PRs for making the new OWNERS based maintenance model a
little more formal. As described in the CONTRIBUTING file, the
maintainership for each of our 3.0 repos[1] is split between reviewers and
approvers. The latter group is a subset of the former and have the final last
word for merging a PR. A PR must be LGTM'ed by one member of each group
before being merged.
On the technical leadership front, Damien Lespiau (@dlespiau) will be the
project technical lead, at least until we reach our first 3.0.0 release [2].
Please let us know if you have any questions/concerns.
Cheers,
Samuel.
