The RPM -contains a collection of configuration file, prebuilt disk images, -and the automatic deployment script (``opnfv-deploy``). - -An OPNFV install requires a "Jumphost" in order to operate. The bootable -ISO will allow you to install a customized CentOS 7 release to the Jumphost, -which includes the required packages needed to run ``opnfv-deploy``. -If you already have a Jumphost with CentOS 7 installed, you may choose to -skip the ISO step and simply install the (``opnfv-apex.rpm``) RPM. The RPM -is the same RPM included in the ISO and includes all the necessary disk -images and configuration files to execute an OPNFV deployment. Either method -will prepare a host to the same ready state for OPNFV deployment. - -``opnfv-deploy`` instantiates an RDO Manager Instack VM server using libvirt -as its provider. This VM is then configured and used to provision the -OPNFV target deployment (3 controllers, n compute nodes). These nodes can -be either virtual or bare metal. This guide contains instructions for -installing either method. - -Triple-O Deployment Architecture -================================ - -Apex is based on RDO Manager which is the RDO Project's implementation of -the OpenStack Triple-O project. It is important to understand the basics -of a Triple-O deployment to help make decisions that will assist in -successfully deploying OPNFV. - -Triple-O stands for OpenStack On OpenStack. This means that OpenStack -will be used to install OpenStack. The target OPNFV deployment is an -OpenStack cloud with NFV features built-in that will be deployed by a -smaller all-in-one deployment of OpenStack. In this deployment -methodology there are two OpenStack installations. They are referred -to as the undercloud and the overcloud. The undercloud is used to -deploy the overcloud. - -The undercloud is the all-in-one installation of OpenStack that includes -baremetal provisioning. RDO Manager's deployment of the undercloud is -call Instack. Instack will be deployed as a virtual machine on a jumphost. -This VM is pre-built and distributed as part of the Apex RPM. - -The overcloud is OPNFV. Configuration will be passed into Instack and -Instack will use OpenStack's orchestration component call Heat to -execute a deployment will provision the target nodes to become OPNFV. - - - -Setup Requirements -================== - -Jumphost Requirements ---------------------- - -The Jumphost requirements are outlined below: - -1. CentOS 7 (from ISO or self-installed). - -2. Root access. - -3. libvirt virtualization support. - -4. minimum 2 networks and maximum 6 networks, multiple NIC and/or VLAN combinations are supported. - This is virtualized for a VM deployment. - -5. The Bramaputra Apex RPM. - -6. 16 GB of RAM for a bare metal deployment, 56 GB of RAM for a VM deployment. - -Network Requirements --------------------- - -Network requirements include: - -1. No DHCP or TFTP server running on networks used by OPNFV. - -2. 2-6 separate networks with connectivity between Jumphost and nodes. - - - Control Plane Network (Provisioning) - - - Private / Internal Network* - - - External Network - - - Storage Network* - -3. Lights out OOB network access from Jumphost with IPMI node enabled (bare metal deployment only). - -4. Admin or public network has Internet access, meaning a gateway and DNS availability. - -| `*` *These networks can be combined with each other or all combined on the Control Plane network.* -| `*` *Non-External networks will be consolidated to the Control Plane network if not specifically configured.* - -Bare Metal Node Requirements ----------------------------- - -Bare metal nodes require: - -1. IPMI enabled on OOB interface for power control. - -2. BIOS boot priority should be PXE first then local hard disk. - -3. BIOS PXE interface should include Control Plane network mentioned above. - -Execution Requirements (Bare Metal Only) ----------------------------------------- - -In order to execute a deployment, one must gather the following information: - -1. IPMI IP addresses for the nodes. - -2. IPMI login information for the nodes (user/pass). - -3. MAC address of Control Plane / Provisioning interfaces of the overcloud nodes. - - -Installation High-Level Overview - Bare Metal Deployment -======================================================== - -The setup presumes that you have 6 bare metal servers and have already setup network -connectivity on at least 2 interfaces for all servers via a TOR switch or other -network implementation. - -The physical TOR switches are **not** automatically configured from the OPNFV reference -platform. All the networks involved in the OPNFV infrastructure as well as the provider -networks and the private tenant VLANs needs to be manually configured. - -The Jumphost can be installed using the bootable ISO or by other means including the -(``opnfv-apex``) RPM and virtualization capabilities. The Jumphost should then be -configured with an IP gateway on its admin or public interface and configured with a -working DNS server. The Jumphost should also have routable access to the lights out network. - -``opnfv-deploy`` is then executed in order to deploy the Instack VM. ``opnfv-deploy`` uses -three configuration files in order to know how to install and provision the OPNFV target system. -The information gathered under section `Execution Requirements (Bare Metal Only)`_ is put -into the YAML file (``/etc/opnfv-apex/inventory.yaml``) configuration file. Deployment -options are put into the YAML file (``/etc/opnfv-apex/deploy_settings.yaml``). Networking -definitions gathered under section `Network Requirements`_ are put into the YAML file -(``/etc/opnfv-apex/network_settings.yaml``). ``opnfv-deploy`` will boot the Instack VM -and load the target deployment configuration into the provisioning toolchain. This includes -MAC address, IPMI, Networking Environment and OPNFV deployment options. - -Once configuration is loaded and Instack is configured it will then reboot the nodes via IPMI. -The nodes should already be set to PXE boot first off the admin interface. The nodes will -first PXE off of the Instack PXE server and go through a discovery/introspection process. - -Introspection boots off of custom introspection PXE images. These images are designed to look -at the properties of the hardware that is booting off of them and report the properties of -it back to the Instack node. - -After introspection Instack will execute a Heat Stack Deployment to being node provisioning -and configuration. The nodes will reboot and PXE again off the Instack PXE server to -provision each node using the Glance disk images provided by Instack. These disk images -include all the necessary packages and configuration for an OPNFV deployment to execute. -Once the node's disk images have been written to disk the nodes will boot off the newly written -disks and execute cloud-init which will execute the final node configuration. This -configuration is largly completed by executing a puppet apply on each node. - -Installation High-Level Overview - VM Deployment -================================================ - -The VM nodes deployment operates almost the same way as the bare metal deployment with a -few differences. ``opnfv-deploy`` still deploys an Instack VM. In addition to the Instack VM -a collection of VMs (3 control nodes + 2 compute for an HA deployment or 1 control node and -1 compute node for a Non-HA Deployment) will be defined for the target OPNFV deployment. -The part of the toolchain that executes IPMI power instructions calls into libvirt instead of -the IPMI interfaces on baremetal servers to operate the power managment. These VMs are then -provisioned with the same disk images and configuration that baremetal would be. - -To RDO Manager these nodes look like they have just built and registered the same way as -bare metal nodes, the main difference is the use of a libvirt driver for the power management. - -Installation Guide - Bare Metal Deployment -========================================== - -**WARNING: Baremetal documentation is not complete. WARNING: The main missing instructions are r elated to bridging -the networking for the undercloud to the physical underlay network for the overcloud to be deployed to.** - -This section goes step-by-step on how to correctly install and provision the OPNFV target -system to bare metal nodes. - -Install Bare Metal Jumphost ---------------------------- - -1a. If your Jumphost does not have CentOS 7 already on it, or you would like to do a fresh - install, then download the Apex bootable ISO from OPNFV artifacts <http://artifacts.opnfv.org/>. - -1b. If your Jump host already has CentOS 7 with libvirt running on it then install the - opnfv-apex RPM from OPNFV artifacts <http://artifacts.opnfv.org/>. - -2a. Boot the ISO off of a USB or other installation media and walk through installing OPNFV CentOS 7. - The ISO comes prepared to be written directly to a USB drive with dd as such: - - ``dd if=opnfv-apex.iso of=/dev/sdX bs=4M`` - - Replace /dev/sdX with the device assigned to your usb drive. Then select the USB device as the - boot media on your Jumphost - -2b. Install the RDO Release RPM and the opnfv-apex RPM: - - ``sudo yum install -y https://www.rdoproject.org/repos/rdo-release.rpm opnfv-apex-{version}.rpm`` - - The RDO Project release repository is needed to install OpenVSwitch, which is a dependency of - opnfv-apex. If you do not have external connectivity to use this repository you need to download - the OpenVSwitch RPM from the RDO Project repositories and install it with the opnfv-apex RPM. - -3. After the operating system and the opnfv-apex RPM are installed, login to your Jumphost as root. - -4. Configure IP addresses on the interfaces that you have selected as your networks. - -5. Configure the IP gateway to the Internet either, preferably on the public interface. - -6. Configure your ``/etc/resolv.conf`` to point to a DNS server (8.8.8.8 is provided by Google). - -Creating a Node Inventory File ------------------------------- - -IPMI configuration information gathered in section `Execution Requirements (Bare Metal Only)`_ -needs to be added to the ``inventory.yaml`` file. - -1. Edit ``/etc/apex-opnfv/inventory.yaml``. - -2. The nodes dictionary contains a definition block for each baremetal host that will be deployed. - 1 or more compute nodes and 3 controller nodes are required. - (The example file contains blocks for each of these already). - It is optional at this point to add more compute nodes into the node list. - -3. Edit the following values for each node: - - - ``mac_address``: MAC of the interface that will PXE boot from Instack - - ``ipmi_ip``: IPMI IP Address - - ``ipmi_user``: IPMI username - - ``ipmi_password``: IPMI password - - ``ipmi_type``: Power Management driver to use for the node - - ``cpus``: (Introspected*) CPU cores available - - ``memory``: (Introspected*) Memory available in Mib - - ``disk``: (Introspected*) Disk space available in Gb - - ``arch``: (Introspected*) System architecture - - ``capabilities``: (Optional**) Intended node role (profile:control or profile:compute) - -* Introspection looks up the overcloud node's resources and overrides these value. You can -leave default values and Apex will get the correct values when it runs introspection on the nodes. - -** If capabilities profile is not specified then Apex will select node's roles in the OPNFV cluster -in a non-deterministic fashion. - -Creating the Settings Files ------------------------------------ - -Edit the 2 settings files in /etc/opnfv-apex/. These files have comments to help you customize them. - -1. deploy_settings.yaml - This file includes basic configuration options deployment. - -2. network_settings.yaml - This file provides Apex with the networking information that satisfies the - prerequisite `Network Requirements`_. These are specific to your environment. - -Running ``opnfv-deploy`` ------------------------- - -You are now ready to deploy OPNFV using Apex! -``opnfv-deploy`` will use the inventory and settings files to deploy OPNFV. - -Follow the steps below to execute: - -1. Execute opnfv-deploy - ``sudo opnfv-deploy [ --flat | -n network_setttings.yaml ] -i instackenv.json -d deploy_settings.yaml`` - If you need more information about the options that can be passed to opnfv-deploy use ``opnfv-deploy --help`` - --flat will collapse all networks onto a single nic, -n network_settings.yaml allows you to customize your - networking topology. - -2. Wait while deployment is executed. - If something goes wrong during this part of the process, - it is most likely a problem with the setup of your network or the information in your configuration files. - You will also notice different outputs in your shell. - -3. The message "Overcloud Deployed" will display when When the deployment is complete. Just above this message there - will be a URL that ends in port http://<host>:5000. This url is also the endpoint for the OPNFV Horizon Dashboard - if connected to on port 80. - -Verifying the Setup -------------------- - -Once the deployment has finished, the OPNFV deployment can be accessed via the Instack node. From -the jump host ssh to the instack host and become the stack user. Alternativly ssh keys have been -setup such that the root user on the jump host can ssh to Instack directly as the stack user. - -| ``ssh root@192.0.2.1`` -| ``su - stack`` - -Once connected to Instack as the stack user look for two keystone files that can be used to -interact with the undercloud and the overcloud. Source the appropriate RC file to interact with -the respective OpenStack deployment. - -| ``source stackrc`` (undercloud / Instack) -| ``source overcloudrc`` (overcloud / OPNFV) - -The contents of these files include the credentials for the administrative user for Instack and -OPNFV respectivly. At this point both Instack and OPNFV can be interacted with just as any -OpenStack installation can be. Start by listing the nodes in the undercloud that were used -to deploy the overcloud. - -| ``source stackrc`` -| ``openstack server list`` - -The control and compute nodes will be listed in the output of this server list command. The IP -addresses that are listed are the control plane addresses that were used to provision the nodes. -Use these IP addresses to connect to these nodes. Initial authentication requires using the -user heat-admin. - -| ``ssh heat-admin@192.0.2.7`` - -To begin creating users, images, networks, servers, etc in OPNFV source the overcloudrc file or -retrieve the admin user's credentials from the overcloudrc file and connect to the web Dashboard. - - -You are now able to follow the `OpenStack Verification`_ section. - -OpenStack Verification ----------------------- - -Once connected to the OPNFV Dashboard make sure the OPNFV target system is working correctly: - -1. In the left pane, click Compute -> Images, click Create Image. - -2. Insert a name "cirros", Insert an Image Location - ``http://download.cirros-cloud.net/0.3.4/cirros-0.3.4-x86_64-disk.img``. - -3. Select format "QCOW2", select Public, then click Create Image. - -4. Now click Project -> Network -> Networks, click Create Network. - -5. Enter a name "internal", click Next. - -6. Enter a subnet name "internal_subnet", and enter Network Address ``172.16.1.0/24``, click Next. - -7. Now go to Project -> Compute -> Instances, click Launch Instance. - -8. Enter Instance Name "first_instance", select Instance Boot Source "Boot from image", - and then select Image Name "cirros". - -9. Click Launch, status will cycle though a couple states before becoming "Active". - -10. Steps 7 though 9 can be repeated to launch more instances. - -11. Once an instance becomes "Active" their IP addresses will display on the Instances page. - -12. Click the name of an instance, then the "Console" tab and login as "cirros"/"cubswin:)" - -13. To verify storage is working, click Project -> Compute -> Volumes, Create Volume - -14. Give the volume a name and a size of 1 GB - -15. Once the volume becomes "Available" click the dropdown arrow and attach it to an instance. - -Congratulations you have successfully installed OPNFV! - -Installation Guide - VM Deployment -================================== - -This section goes step-by-step on how to correctly install and provision the OPNFV target system to VM nodes. - -Install Jumphost ----------------- - -Follow the instructions in the `Install Bare Metal Jumphost`_ section. - -Running ``opnfv-deploy`` ------------------------- - -You are now ready to deploy OPNFV! -``opnfv-deploy`` has virtual deployment capability that includes all of -the configuration nessesary to deploy OPNFV with no modifications. - -If no modifications are made to the included configurations the target environment -will deploy with the following architecture: - - - 1 Instack VM - - - The option of 3 control and 2 compute VMs (HA Deploy / default) - or 1 control and 1 compute VM (Non-HA deploy / pass -n) - - - 2 networks, one for provisioning, internal API, - storage and tenant networking traffic and a second for the external network - -Follow the steps below to execute: - -1. ``sudo opnfv-deploy --virtual [ --no-ha ]`` - -2. It will take approximately 30 minutes to stand up instack, - define the target virtual machines, configure the deployment and execute the deployment. - You will notice different outputs in your shell. - -3. When the deployment is complete you will see "Overcloud Deployed" - -Verifying the Setup - VMs -------------------------- - -To verify the set you can follow the instructions in the `Verifying the Setup`_ section. - -Before you get started following these instructions you will need to add IP addresses on the networks that have been -created for the External and provisioning networks. By default the External network is 192.168.37.0/24 and the -provisioning network is 192.0.2.0/24. To access these networks simply add an IP to brbm and brbm1 and set their link to -up. This will provide a route from the hypervisor into the virtual networks acting as OpenStack's underlay network in -the virtual deployment. - -| ``ip addr add 192.0.2.252/24 dev brbm`` -| ``ip link set up dev brbm`` -| ``ip addr add 192.168.37.252/24 dev brbm1`` -| ``ip link set up dev brbm1`` - -Once these IP addresses are assigned and the links are up the gateways on the overcloud's networks should be pingable -and read to be SSHed to. - -| ``ping 192.0.2.1`` -| ``ping 192.168.37.1`` - -Now continue with the `Verifying the Setup`_ section. - -OpenStack Verification - VMs ----------------------------- - -Follow the steps in `OpenStack Verification`_ section. - -Frequently Asked Questions -========================== - -License -======= - -All Apex and "common" entities are protected by the `Apache 2.0 License <http://www.apache.org/licenses/>`_. - -References -========== - -OPNFV ------ - -`OPNFV Home Page <www.opnfv.org>`_ - -`OPNFV Genesis project page <https://wiki.opnfv.org/get_started>`_ - -`OPNFV Apex project page <https://wiki.opnfv.org/apex>`_ - -OpenStack ---------- - -`OpenStack Liberty Release artifacts <http://www.openstack.org/software/liberty>`_ - -`OpenStack documentation <http://docs.openstack.org>`_ - -OpenDaylight ------------- - -Upstream OpenDaylight provides `a number of packaging and deployment options <https://wiki.opendaylight.org/view/Deployment>`_ meant for consumption by downstream projects like OPNFV. - -Currently, OPNFV Apex uses `OpenDaylight's Puppet module <https://github.com/dfarrell07/puppet-opendaylight>`_, which in turn depends on `OpenDaylight's RPM <http://cbs.centos.org/repos/nfv7-opendaylight-3-candidate/x86_64/os/Packages/opendaylight-3.0.0-2.el7.noarch.rpm>`_. - -RDO Manager ------------ - -`RDO Manager website <https://www.rdoproject.org/rdo-manager>`_ - -:Authors: Tim Rozet (trozet@redhat.com) -:Authors: Dan Radez (dradez@redhat.com) -:Version: 1.0 |
