Platform9 Express (pf9-express) is a Customer Success developed tool for bringing bare-metal hosts under management by a Platform9 management plane. It can bring a host to the point where it shows up in the Clarity UI as a host waiting to be authorized, or it can (optionally) perform Platform9 role deployments for both OpenStack and Kubernetes. Platform9 Express includes a CLI and Web UI and can be installed on a CentOS or Ubuntu control host.
Platform9 Express must be installed on a control host with IP connectivity to the hosts to be brought under management. CentOS 7.4 or Ubuntu 16.04 are supported on the control host. Before installing Platform9 Express, you'll need administrator credentials for the Platform9 management plane. If a proxy is required for HTTP/HTTPS traffic, you'll need the URL for the proxy.
Perform the following steps to install Platform9 Express:
-
Login as root (or a user with sudo access) on the host that you plan to install Platform9 Express on.
-
Install git
yum install git # CentOS
apt-get update && apt-get install git # Ubuntu
- Clone the Platform9 Express repository.
git clone https://github.com/platform9/express.git /opt/pf9-express
NOTE: In this example, the installation directory is /opt/pf9-express, but any directory can be used.
To configure the Platform9 Express CLI to communicate with the Platform9 management plane, run the following command (a sample session is included):
# ./pf9-express -s
NOTE: to enter a NULL value for prompt, enter '-'

Platform9 Express uses Ansible to execute commands on the hosts to be taken under management. In order to configure Ansible to run remote commands on the managed hosts, the Ansible Inventory file must be configured. This file is located in /opt/pf9-express/inventory/hosts.
NOTE: A sample template is installed in the previous command ("./pf9-express -s").

Instead of manually configuring the inventory file, you can us the '-f ' option to auto-configure it from a CSV definition file.
Here's a sample CSV definition file:
hostname,username,key,ip,dhcp,snat,glance,glance-public,nic1,nic2,mgmtvlan,mgmtip,mgmtnetmask,Storagevlan,storageip,storagenetmask,tunnelvlan,tunnelip,tunnelnetmask

If you want to control the UID and GID values for the Platform9 service account (pf9/pf9group), set the following inventory variables:
- pf9_uid
- pf9_gid
If these variables are not defined, the Host Agent Installer will allow the system to auto-assign the UID and GID.
NOTE: This feature is not idempotent. If the 'pf9' user had not been created yet, Platform9 Express will create the 'pf9' user and 'pf9group' group based on the values of pf9_uid and pf9_gid. If the 'pf9' user already exists, Platform9 Express will skip the user/group management section; it will not attempt to alter the UID/GID settings.
The basic syntax for starting Platform9 Express includes a target (host group, individual host, comma-delimited list of hosts, or "all" to run all groups) and an optional flag ('-a') that instructs it to perform role deployment.
Here's an example of invoking Platform9 Express against a number of hosts:

Here's the usage statement showing all command-line options:
# ./pf9-express
Usage: ./pf9-express [Args] <target>
Args (Optional):
-a|--autoRegister : auto-register host with management plane
-i|--installPrereqs : install pre-requisites and exit
-s|--setup : run setup and exit
-o|--oscli : install OpenStack CLI
-c|--config <configFile> : use custom configuration file
-e|--extra-vars <string> : ansible extra-vars <name=val,...>
-b|--bypassPrereqs : bypass pre-requisites

If you have more than one Platform9 region to manage, you can create a configuration file for each one (using pf9-express.conf as a template) and start pf9-express with the '-c' flag:
./pf9-express -c ~/pf9-site1.conf -a hv01
If you want to override an Ansible variable defined in Inventory or dynamically within playbooks, you can invoke pf9-express with the '-e' flag:
./pf9-express -c ~/pf9-express.conf -a -e "proxy_url=https://proxy1.platform9.net" hv01
