This appendix describes how to write a scripts to invoke all of the scripts from a single host.
It is possible to write a script to invoke all of the scripts from a single host, in effect creating a one command deployment.
Below are sample scripts which can be modified to achieve this.
Disclaimer:
These scripts are example implementations and are provided as is as a proof of concept to demonstrate a method to automate the deployment process. The scripts must be customized and tested for the specific need of your environment.
This appendix includes the following topics:

# NAME
# provision.sh - this script starts executing Deployment phases in all hosts
#
# DESCRIPTION
# <short description of component this file declares/defines>
#
# NOTES
# - copy all scripts named prov_*.sh to a directory in primordial host
# - make sure this directory is accessible using the same path from all hosts being provisioned
# - update prov_env.sh with environment specific details (directories, hostnames, db, etc)
# - run this script from the primordial host
# - script will create one log file for each phase in each host - named prov_run-<phase>-<host>.log
# - script will stop when Deployment completes or on detecting 1st failure (absence of "BUILD SUCCESSFUL" in the log file)

Use the scripts as follows:
Copy the scripts to a location that is available on each host in the topology.
Edit the scripts and replace entries like <SW_ROOT> with entries applicable to your environment. Use Section 7.1, "Assembling Information for Identity and Access Management Deployment," to assist with this.
Set up ssh equivalence from the primordial host to each of the other hosts in the topology. See your operating system documentation for details.
Validate that ssh equivalence is working by issuing the following command from the primordial host to each host in the topology. This command should show the date on each remote machine without any prompts:
ssh hostname date
Copy the deployment response file generated in Chapter 8, "Creating a Deployment Profile," to the same directory where these scripts are located.
Run the deploy.sh script.
After deployment is complete, remove the ssh equivalence.
