Update the Euphrates docs for kubernetes scenario
JIRA: - In the Euphrates release, compass has supported kubernates deployment now. However, there is no k8s related description in docs of compass4nfv. So we add k8s related description in this patch including the k8s architeture, k8s networking in Compass, k8s virtual deployment and k8s bare metel deployment. Change-Id: I3bea3ae06b1c73076ba44d10caf89602928b7021 Signed-off-by: Yifei Xue <xueyifei@huawei.com>

+Installation of K8s on virtual machines
+=======================================
+
+Quick Start
+-----------
+
+Only 1 command to try virtual deployment, if you have Internet access. Just Paste it and Run.
+
+.. code-block:: bash
+
+ curl https://raw.githubusercontent.com/opnfv/compass4nfv/master/quickstart_k8s.sh | bash
+
+If you want to deploy noha with1 controller and 1 compute, run the following command
+
+.. code-block:: bash
+
+ export SCENARIO=k8-nosdn-nofeature-noha.yml
+ export VIRT_NUMBER=2
+ curl https://raw.githubusercontent.com/opnfv/compass4nfv/euphrates/quickstart_k8s.sh | bash
+
+Installation of K8s on Bare Metal
+=================================
+
+Nodes Configuration (Bare Metal Deployment)
+-------------------------------------------
+
+The below file is the inventory template of deployment nodes:
+
+"compass4nfv/deploy/conf/hardware_environment/huawei-pod1/k8-nosdn-nofeature-ha.yml"
+
+You can write your own IPMI IP/User/Password/Mac address/roles reference to it.
+
+ - name -- Host name for deployment node after installation.
+
+ - ipmiVer -- IPMI interface version for deployment node support. IPMI 1.0
+ or IPMI 2.0 is available.
+
+ - ipmiIP -- IPMI IP address for deployment node. Make sure it can access
+ from Jumphost.
+
+ - ipmiUser -- IPMI Username for deployment node.
+
+ - ipmiPass -- IPMI Password for deployment node.
+
+ - mac -- MAC Address of deployment node PXE NIC.
+
+ - interfaces -- Host NIC renamed according to NIC MAC addresses when OS provisioning.
+
+ - roles -- Components deployed.
+
+**Set TYPE/FLAVOR and POWER TOOL**
+
+E.g.
+.. code-block:: yaml
+
+ TYPE: baremetal
+ FLAVOR: cluster
+ POWER_TOOL: ipmitool
+
+**Set ipmiUser/ipmiPass and ipmiVer**
+
+E.g.
+
+.. code-block:: yaml
+
+ ipmiUser: USER
+ ipmiPass: PASSWORD
+ ipmiVer: '2.0'
+
+**Assignment of different roles to servers**
+
+E.g. K8s only deployment roles setting
+
+.. code-block:: yaml
+
+ hosts:
+ - name: host1
+ mac: 'F8:4A:BF:55:A2:8D'
+ interfaces:
+ - eth1: 'F8:4A:BF:55:A2:8E'
+ ipmiIp: 172.16.130.26
+ roles:
+ - kube_master
+ - etcd
+
+ - name: host2
+ mac: 'D8:49:0B:DA:5A:B7'
+ interfaces:
+ - eth1: 'D8:49:0B:DA:5A:B8'
+ ipmiIp: 172.16.130.27
+ roles:
+ - kube_node
+
+Network Configuration (Bare Metal Deployment)
+---------------------------------------------
+
+Before deployment, there are some network configuration to be checked based
+on your network topology.Compass4nfv network default configuration file is
+"compass4nfv/deploy/conf/hardware_environment/huawei-pod1/network.yml".
+This file is an example, you can customize by yourself according to specific network
+environment.
+
+In this network.yml, there are several config sections listed following(corresponed to the
+ordre of the config file):
+
+Provider Mapping
+~~~~~~~~~~~~~~~~
+
+ - name -- provider network name.
+
+ - network -- default as physnet, do not change it.
+
+ - interfaces -- the NIC or Bridge attached by the Network.
+
+ - type -- the type of the NIC or Bridge(vlan for NIC and ovs for Bridge, either).
+
+ - roles -- all the possible roles of the host machines which connected by this
+ network(mostly put both controller and compute).
+
+System Interface
+~~~~~~~~~~~~~~~~
+
+ - name -- Network name.
+
+ - interfaces -- the NIC or Bridge attached by the Network.
+
+ - vlan_tag -- if type is vlan, add this tag before 'type' tag.
+
+ - type -- the type of the NIC or Bridge(vlan for NIC and ovs for Bridge, either).
+
+ - roles -- all the possible roles of the host machines which connected by this
+ network(mostly put both controller and compute).
+
+IP Settings
+~~~~~~~~~~~
+
+ - name -- network name corresponding the the network name in System Interface section one by one.
+
+ - ip_ranges -- ip addresses range provided for this network.
+
+ - cidr -- the IPv4 address and its associated routing prefix and subnet mask?
+
+ - gw -- need to add this line only if network is external.
+
+ - roles -- all the possible roles of the host machines which connected by this
+ network(mostly put both controller and compute).
+
+Internal VIP(virtual or proxy IP)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+ - ip -- virtual or proxy ip address, must be in the same subnet with mgmt network
+ but must not be in the range of mgmt network.
+
+ - netmask -- the length of netmask
+
+ - interface -- mostly mgmt.
+
+Public VIP
+~~~~~~~~~~
+
+ - ip -- virtual or proxy ip address, must be in the same subnet with external
+ network but must not be in the range of external network.
+
+ - netmask -- the length of netmask
+
+ - interface -- mostly external.
+
+
+Public Network
+~~~~~~~~~~~~~~
+
+ - enable -- must be True(if False, you need to set up provider network manually).
+
+ - network -- leave it ext-net.
+
+ - type -- the type of the ext-net above, such as flat or vlan.
+
+ - segment_id -- when the type is vlan, this should be id of vlan.
+
+ - subnet -- leave it ext-subnet.
+
+ - provider_network -- leave it physnet.
+
+ - router -- leave it router-ext.
+
+ - enable_dhcp -- must be False.
+
+ - no_gateway -- must be False.
+
+ - external_gw -- same as gw in ip_settings.
+
+ - floating_ip_cidr -- cidr for floating ip, see explanation in ip_settings.
+
+ - floating_ip_start -- define range of floating ip with floating_ip_end(this
+ defined range must not be included in ip range of external configured in
+ ip_settings section).
+
+ - floating_ip_end -- define range of floating ip with floating_ip_start.
+

+
+Start Deployment (Bare Metal Deployment)
+----------------------------------------
+
+1. Edit deploy.sh
+
+1.1. Set OS version for deployment nodes.
+ Compass4nfv supports ubuntu and centos based openstack newton.
+
+E.g.
+
+.. code-block:: bash
+
+ # Set OS version for target hosts
+ # Only CentOS7 supported now
+ export OS_VERSION=centos7
+
+1.2. Set tarball corresponding to your code
+
+E.g.
+
+.. code-block:: bash
+
+ # Set ISO image corresponding to your code
+ export ISO_URL=file:///home/compass/compass4nfv.tar.gz
+
+1.3. Set hardware deploy jumpserver PXE NIC. (set eth1 E.g.)
+ You do not need to set it when virtual deploy.
+
+E.g.
+
+.. code-block:: bash
+
+ # Set hardware deploy jumpserver PXE NIC
+ # you need to comment out it when virtual deploy
+ export INSTALL_NIC=eth1
+
+1.4. K8s scenario that you want to deploy
+
+E.g.
+
+nosdn-nofeature scenario deploy sample
+
+.. code-block:: bash
+
+ # DHA is your dha.yml's path
+ export DHA=./deploy/conf/hardware_environment/huawei-pod1/k8-nosdn-nofeature-ha.yml
+
+ # NETWORK is your network.yml's path
+ export NETWORK=./deploy/conf/hardware_environment/huawei-pod1/network.yml
+
+2. Run ``deploy.sh``
+
+.. code-block:: bash
+
+ ./deploy.sh

+K8s introduction
+================
+
+Kubernetes Architecture
+-----------------------
+
+Currently Compass can deploy kubernetes as NFVI in 3+2 mode by default.
+
+**The following figure shows a typical architecture of Kubernetes.**
+
+.. figure:: images/architecture.png
+ :alt: K8s architecture
+ :figclass: align-center
+
+ Fig 3. K8s architecture
+
+Kube-apiserver
+~~~~~~~~~~~~~~
+
+Kube-apiserver exposes the Kubernetes API. It is the front-end for the Kubernetes control plane.
+It is designed to scale horizontally, that is, it scales by deploying more instances.
+
+Etcd
+~~~~
+
+Etcd is used as Kubernetes' backing store. All cluster data is stored here. Always have a backup
+plan for etcd's data for your Kubernetes cluster.
+
+Kube-controller-manager
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Kube-controller-manager runs controllers, which are the background threads that handle routine
+tasks in the cluster. Logically, each controller is a separate process, but to reduce complexity,
+they are all compiled into a single binary and run in a single process.
+
+These controllers include:
+
+ - Node Controller: Responsible for noticing and responding when nodes go down.
+ - Replication Controller: Responsible for maintaining the correct number of pods for every
+ replication controller object in the system.
+ - Endpoints Controller: Populates the Endpoints object (that is, joins Services & Pods).
+ - Service Account & Token Controllers: Create default accounts and API access tokens for
+ new namespaces.
+
+kube-scheduler
+~~~~~~~~~~~~~~
+
+Kube-scheduler watches newly created pods that have no node assigned, and selects a node for them
+to run on.
+
+Kubelet
+~~~~~~~
+
+Kubelet is the primary node agent. It watches for pods that have been assigned to its node (either
+by apiserver or via local configuration file) and:
+
+ - Mounts the pod's required volumes.
+ - Downloads the pod's secrets.
+ - Runs the pod's containers via docker (or, experimentally, rkt).
+ - Periodically executes any requested container liveness probes.
+ - Reports the status of the pod back to the rest of the system, by creating a mirror pod if
+ necessary.
+ - Reports the status of the node back to the rest of the system.
+
+Kube-proxy
+~~~~~~~~~~
+
+Kube-proxy enables the Kubernetes service abstraction by maintaining network rules on the host and
+performing connection forwarding.
+
+Docker
+~~~~~~
+
+Docker is used for running containers.
+
+POD
+~~~
+
+A pod is a collection of containers and its storage inside a node of a Kubernetes cluster. It is
+possible to create a pod with multiple containers inside it. For example, keeping a database container
+and data container in the same pod.
+
+Understand Kubernetes Networking in Compass configuration
