This is the main Heat template for the 3-tier LAMP Workload created by the Enterprise WG.
|
|
This version of the tempalte does not include autoscaling, and does not require ceilometer.
|
|
This template calls multiple nested templates which actually do the
|
|
majority of the work. This file calls the following yaml files in a ./lib subdirectory
|
|
setup_net_sg.yaml sets up the security groups and networks for Web, App, and Database
|
|
heat_app_tier.yaml starts up application servers and does on-the-fly builds
|
|
heat_web_tier.yaml starts up web servers and does on-the-fly builds
|
|
heat_sql_tier.yaml starts up mysql server and does on-the-fly builds.
|
|
|
|
NOTE: This serves as a guide to new users and is not meant for production deployment.
|
|
|
|
REQUIRED YAML FILES:
|
|
setup_net_sg.yaml, heat_app_tier.yaml, heat_sql_tier.yaml, heat_web_tier.yaml
|
|
|
|
REQUIRED PARAMETERS:
|
|
ssh_key_name, image_id, public_network_id
|
|
|
|
OPTIONAL PARAMETERS:
|
|
db_instance_flavor, app_instance_flavor, web_instance_flavor, db_server_name, app_server_name, web_server_name, dns_nameserver
