[Q] Steps to deploy the Kubernetes Cluster with Stratos
Hi, Dev
Need to clarify how to deploy the Kubernetes Cluster with following
features:
1. How can we deploy the LB in Kubernetes Cluster? (need the detail steps)
2. How to realize the auto scaling in Kubernetes Cluster? If this scaling
with new instance or add more containers?
3. How the new node to be added to Kubernetes nodes automatically? Do we
need manually config?
4. CoreOs is current focus on their Rkt, Wondering, if the Kubernetes -
CoreOS is a best approach with Docker - Container solution?
5. Base on the above concerns, I would like to use Kubernetes - RHEL,
instead of Kubernetes - CoreOS. Is there any instruction that I can deploy
the Strato - Kubernetes- RHEL?
Thanks

Hi David,
Yes we already have Stratos Kubernetes environments running, you can refer
below document for this:
https://gist.github.com/imesh/b8f81fac8de39183a504
We also have verified group scaling functionality on Mock IaaS & OpenStack,
it should also work the same on Kubernetes.

Hi, Imesh
Would like to know if anyone has successful deployed the K8s -- Stratos
with Group-scaling functions?
I am still not clarify the detail steps to deploy the K8s -- Stratos with
group-scaling functions. If anyone can contribute with his experience
and/or step by step detail instructions will be great helpful.
Thanks

Re: [Q] Steps to deploy the Kubernetes Cluster with Stratos
Posted by Imesh Gunaratne <im...@apache.org>.
Hi David,
The high level deployment architecture would be as follows:
If required an external load balancer can be used in front of the
Kubernetes cluster or with multiple Kubernetes clusters.

Re: [Q] Steps to deploy the Kubernetes Cluster with Stratos

Since in k8s, the kube_proxy do simple TCP stream forwarding or round robin
TCP forwarding across a set of backends. The issue is, how can the Stratos
communicate with the kube_proxy?
Thanks

No I do not think this is fully documented yet. We now have several load
balancers (Stratos, haproxy, nginx, LVS) so will need to document each
separately. Anyway for this we have two high level options:
1. Start a load balancer for the entire Stratos deployment.
2. Start a load balancer and configure it to serve a specific cluster,
group or application.
Currently we only have the following Wiki which describes how to configure
Stratos load balancer (this also need to be further refined):
