Contrail POC

1 Overview

Pick cluster and underlay to build the POC.

Underlay

  • Bridge
    • Contrail integration deployment.
    • Contrail basic features.
  • Gateway MX
    • Overlay-underlay connectivity via MX.
    • Distributed fabric forwarding (gateway-less mode).
  • IP Fabric
    • Contrail Fabric Management
  • IP Fabric HA
    • Contrail Fabric Management HA
  • Multi-Site
  • Gateway x2
    • Contrail gateway to corp gateway.
    • Contrail gateway to Contrail gateway (DCI).
    • Remote compute.

Cluster

2 Hypervisor

Here are prerequisites for the hypervisor.

  • Resource

    • The hypervisor used by this guide has 32 vCPU, 256GB memory and 2TB disk.
    • At least one NIC that has public/internet access.

  • Host OS

    • CentOS 7.5 and Ubuntu 16.04.3 are validated.

  • Disk partition

    • Optionally, for better disk performance, reserve a partition (1TB) for libvirt volume.
    • Partition reservation has to be done during host OS installation.
    • Here is the recommended partition schema for a 2TB disk.
      • Partition 1, 250MB, /boot.
      • Partition 2, 1TB, volume group system.
        • Logical volume swap, 256GB.
        • Logical volume root, the rest space.
      • Partition 3, the rest space (for libvirt volume).

Note: In case no partition is reserved, all VM images will be on file system.

  • Kernel
    • Upgrade kernel and reboot, after installation.

3 Build enviroment

3.1 Setup hypervisor

  • Install git.
yum install git
  • Clone repository.
git clone https://github.com/tonyliu0592/contrail-poc.git
  • Update the followings variables in poc.conf.
    • volume_dev
    • ntp_server

Note, comment out volume_dev if no partition is reserved.

  • Setup the hypervisor.
cd contrail-poc
poc setup-hypervisor

3.2 VM image

Copy the following VM images /opt/vm-image directory.

CentOS-7-x86_64-GenericCloud-1805.qcow2
cirros-0.4.0-x86_64-disk.img
vmx-re.qcow2
vmx-re-hdd.qcow2
metadata-usb-re.img
vFPC-20180829.img
vqfx-pfe.qcow2
vqfx-re.qcow2

3.3 AppFormix

AppFormix is integrated with cluster cfm.

  • Download the following packages from Juniper and upload them to /opt/appformix directory on the hypervisor host.
appformix-3.1.2.tar.gz
appformix-dependencies-images-3.1.2.tar.gz
appformix-kubernetes-images-3.1.2.tar.gz
appformix-network_device-images-3.1.2.tar.gz
appformix-openstack-images-3.1.2.tar.gz
appformix-platform-images-3.1.2.tar.gz

  • Send request to AppFormix-Key-Request.juniper.net for AppFormix license.

  • Copy the license to /opt/appformix directory on the hypervisor host.

  • Update appformix_license in poc.conf.

  • Run poc launch-appformix after building cluster cfm.

Note

For the first time to open AppFormix UI, select skip license upload and skip the installation.

4 Deploy

4.1 Build underlay and cluster

  • Update variables in poc.conf for deployment.

    • Choose underlay and cluster.
    • Set username and password for hub.juniper.net/contrail.
    • Set Contrail container tag and Contrail Command container tag.
    • Set Ansible playbook name.

  • Build underlay and cluster.

poc build-underlay
poc build-cluster

4.2 Change underlay

  • Delete existing underlay.
poc delete-underlay

Note: Delete underlay before updating poc.conf.

  • Update underlay selection in poc.conf.

  • Build new underlay.

poc build-underlay

4.3 Change cluster

  • Delete existing cluster.
poc delete-cluster

Note: Delete cluster before updating poc.conf.

  • Update cluster selection in poc.conf.

  • Build new cluster.

poc build-cluster

5 Access

To access server or underlay device, login onto the host, then ssh to the hostname or management address.

HAProxy is configured to provide access to the cluster.

Contrail web UI:   https://<host>:8143
Contrail Command:  https://<host>:9091
OpenStack Horizon: http://<host>
AppFormix UI:      http://<host>:9000

Default username and password for vQFX and vMX is root / Juniper.

6 Notes

6.1 vQFX

This POC is using these vQFX RE and PFE image.

jinstall-vqfx-10-f-18.1R1.9.img
cosim_20180212.qcow2

With jinstall-vqfx-10-f-18.4R1.8.qcow2, EVPN type-2 MAC/IP route with IP shows up in default-switch.evpn.0. ARP request from BMS is resolved by vQFX, not being multicasted anymore. When VM sends out ARP request for BMS, vrouter doesn't resolve it, but multicasts ARP request. When vQFX resolves request and sends reply back to vrouter, it sets VNI to 0. This is invalid VNI for vrouter. So the reply is dropped by vrouter.

6.2 vMX

This POC is using vMX 18.3R1.9 with trial license.
