Layer7 API Management

Hi Team,

We need to setup CA Gateway environment on AWS.Now my client has a requirement in such a way that need to automate everything from installation to deployment of CA API Gateway in AWS.So if he want to create a new environment he will use this scripts to create it without our support.What level of automation can we do for gateways.And onemore this for CA Gateway AWS  the database will be external.so if we replicate the existing database.can we create the new environment.

Dear d.pradeepkumar1 ,

The amazon AMI support user-data script to initialize the EC2 instance, and gateway supports headless configuration,

Auto-Provision a Gateway Node - CA API Gateway - 9.3 - CA Technologies Documentation 

But running headless-config on AMI is a bit tricky, because headless-config require the gateway is running, but  user-data script is executed before any service startup.

So, only run the headless-config script in user-data script will always fail.

The following user-data works for me (it connects to local mysql, you can change the setting to connect to external mysql)

#!/bin/bash
service mysql start
service ssg start
sleep 2m
echo configure.db=true > create-node.properties
echo database.type=mysql >> create-node.properties
echo database.host=localhost >> create-node.properties
echo database.port=3306 >> create-node.properties
echo database.name=ssg >> create-node.properties
echo database.user=gateway >> create-node.properties
echo database.pass=7layer >> create-node.properties
echo database.admin.user=root >> create-node.properties
echo database.admin.pass=7layer  >> create-node.properties
echo node.enable=true >> create-node.properties
echo configure.node=true >> create-node.properties
echo admin.user=admin >> create-node.properties
echo admin.pass=7layer >> create-node.properties
echo cluster.host=`hostname` >> create-node.properties
echo cluster.pass=7layer >> create-node.properties
cat create-node.properties | /opt/SecureSpan/Gateway/config/bin/ssgconfig-headless create
# end of script

The /var/log/cloud-init-output.log shows following,
Cloud-init v. 0.7.5 running 'modules:config' at Mon, 05 Feb 2018 23:17:45 +0000. Up 652.75 seconds.
Cloud-init v. 0.7.5 running 'modules:final' at Mon, 05 Feb 2018 23:17:52 +0000. Up 659.44 seconds.
Starting MySQL............. SUCCESS!
Starting Gateway Services: [  OK  ]
Configuration Successful

So, to answer your question, yes, when you have database ready, you can auto-provision new environment on AWS.
