====================
OpenContrail Formula
====================

Contrail Controller is an open, standards-based software solution that
delivers network virtualization and service automation for federated cloud
networks. It provides self-service provisioning, improves network
troubleshooting and diagnostics, and enables service chaining for dynamic
application environments across enterprise virtual private cloud (VPC),
managed Infrastructure as a Service (IaaS), and Networks Functions
Virtualization (NFV) use cases.


Package source
==============

Formula support OpenContrail as well as Juniper Contrail package repository in the backend.

Differences withing the configuration and state run are controlled by
``opencontrail.common.vendor: [opencontrail|juniper]`` pillar attribute.

Default value is set to ``opencontrail``.

Juniper releases tested with this formula:
 - 3.0.2.x

To use Juniper Contrail repository as a source of packages override pillar as in this example:

.. code-block:: yaml

    opencontrail:
      common:
        vendor: juniper

Keystone v3
-----------

To enable support for keystone v3 in opencontrail, there must be defined
version for config and web role.

.. code-block:: yaml

    opencontrail:
      config:
        version: 2.2
        enabled: true
        ...
        identity:
          engine: keystone
          version: '3'
        ...

    opencontrail:
      web:
        version: 2.2
        enabled: true
        ...
        identity:
          engine: keystone
          version: '3'
        ...

Without Keystone
----------------

.. code-block:: yaml

    opencontrail:
      ...
      common:
        ...
        identity:
          engine: none
          token: none
          password: none
        ...
      config:
        ...
        identity:
          engine: none
          password: none
          token: none
        ...
      web:
        ...
        identity:
          engine: none
          password: none
          token: none
        ...

Kubernetes support
------------------

Kubernetes vrouter nodes

Vrouter configuration on a kubernetes node(s)

.. code-block:: yaml

    opencontrail:
      ...
      compute:
        engine: kubernetes
      ...

vRouter with separated control plane

Separate XMPP traffic from dataplane interface.

.. code-block:: yaml

    opencontrail:
      compute:
        bind:
          address: 172.16.0.50
      ...

Disable Contrail API authentication
-----------------------------------

Contrail version must >= 3.0. It is useful especially for Keystone v3.

.. code-block:: yaml

    opencontrail:
      ...
      config:
        multi_tenancy: false
      ...

Switch from on demand to periodic keystone sync
-----------------------------------------------

This can be useful when you want to sync projects from OpenStack to Contrail
automatically. The period of sync is 60s.

.. code-block:: yaml

    opencontrail:
      ...
      config:
        identity:
          sync_on_demand: false
      ...

Cassandra listen interface
--------------------------

.. code-block:: yaml
  
    database:
      ....
      bind:
        interface: eth0
        port: 9042
        rpc_port: 9160
      ....

OpenContrail WebUI version >= 3.1.1
-----------------------------------
For OpenContrail version >= 3.1.1 and Cassandra >= 2.1 we should override WebUI's cassandra port from 9160 to 9042.

For appropriate node at class level:

.. code-block:: yaml

    opencontrail:
      ....
      web:
        database:
          port: 9042
      ....


RabbitMQ HA hosts
------------------

.. code-block:: yaml

    opencontrail:
      config:
        message_queue:
          engine: rabbitmq
          members:
            - host: 10.0.16.1
            - host: 10.0.16.2
            - host: 10.0.16.3
          port: 5672

.. code-block:: yaml

    database:
      ....
      bind:
        interface: eth0
        port: 9042
        rpc_port: 9160
      ....

DPDK vRouter
-------------

.. code-block:: yaml

    opencontrail:
      compute:
        dpdk:
          enabled: true
          taskset: "0x0000003C00003C"
          socket_mem: "1024,1024"
        interface:
          mac_address: 90:e2:ba:7c:22:e1
          pci: 0000:81:00.1
      ...

Contrail client
---------------

Basic parameters with identity and host configs

.. code-block:: yaml

  opencontrail:
    client:
      identity:
        user: admin
        project: admin
        password: adminpass
        host: keystone_host
      config:
        host: contrail_api_host
        port: contrail_api_ort

Debugging
---------

Display vhost XMPP connection status

You should see the correct controller_ip and state should be established.

    http://<compute-node>:8085/Snh_AgentXmppConnectionStatusReq?

Display vrouter interface status

When vrf_name = ---ERROR--- then something goes wrong

    http://<compute-node>:8085/Snh_ItfReq?name=

Display IF MAP table

Look for neighbours, if VM has 2, it's ok

Trace XMPP requests
