January 14 - RackN demo, testing woes, and KubeCon EU CFP.

Note taker: Joe Beda

Demonstration: Automated Deploy on Metal, AWS and others w/ Digital Rebar, Rob Hirschfeld and Greg Althaus from RackN
- Greg Althaus. CTO. Digital Rebar is the product. Bare metal provisioning tool.
- Detect hardware, bring it up, configure raid, OS and get workload deployed.
- Been working on Kubernetes workload.
- Seeing trend to start in cloud and then move back to bare metal.
- New provider model to use provisioning system on both cloud and bare metal.
- UI, REST API, CLI
- Demo: Packet -- bare metal as a service
  - 4 nodes running grouped into a "deployment"
  - Functional roles/operations selected per node.
  - Decomposed the kubernetes bring up into units that can be ordered and synchronized. Dependency tree -- things like wait for etcd to be up before starting k8s master.
  - Using the Ansible playbook under the covers.
  - Demo brings up 5 more nodes -- packet will build those nodes
  - Pulled out basic parameters from the ansible playbook. Things like the network config, dns set up, etc.
  - Hierarchy of roles pulls in other components -- making a node a master brings in a bunch of other roles that are necessary for that.
  - Has all of this combined into a command line tool with a simple config file.
- Forward: extending across multiple clouds for test deployments. Also looking to create split/replicated across bare metal and cloud.
- Q: secrets?
  A: using ansible playbooks. Builds own certs and then distributes them. Wants to abstract them out and push that stuff upstream.
- Q: Do you support bringing up from real bare metal with PXE boot?
  A: yes -- will discover bare metal systems and install OS, install ssh keys, build networking, etc.
[from SIG-scalability] Q: What is the status of moving to golang 1.5?
A: At HEAD we are 1.5 but will support 1.4 also. Some issues with flakiness but looks like things are stable now.
- Also looking to use the 1.5 vendor experiment. Move away from godep. But can't do that until 1.5 is the baseline.
- Sarah: one of the things we are working on is rewards for doing stuff like this. Cloud credits, tshirts, poker chips, ponies.
[from SIG-scalability] Q: What is the status of cleaning up the jenkins based submit queue? What can the community do to help out?
A: It has been rocky the last few days. There should be issues associated with each of these. There is a

* March 10-11 in London.  Venue to be announced this week.

Please send talks! CFP deadline looks to be Feb 5.
Lots of excitement. Looks to be 700-800 people. Bigger than SF version (560 ppl).
Buy tickets early -- early bird prices will end soon and price will go up 100 GBP.
Accommodations provided for speakers?
Q from Bob @ Samsung: Can we get more warning/planning for stuff like this:
- A: Sarah -- I don't hear about this stuff much in advance but will try to pull together a list. Working to make the events page on kubernetes.io easier to use.
- A: JJ -- we'll make sure we give more info earlier for the next US conf.

Scale tests [Rob Hirschfeld from RackN] -- if you want to help coordinate on scale tests we'd love to help.

Bob invited Rob to join the SIG-scale group.
There is also a big bare metal cluster through the CNCF (from Intel) that will be useful too. No hard dates yet on that.

Notes/video going to be posted on k8s blog. (Video for 20150114 wasn't recorded. Fail.)
