= Wrapper script

This script is a wrapper for end-users, to run ansible_agnostic_deployer playbooks.

All the configuration regarding an environment can be set in a .rc file (bash syntax). The script takes the file as first arg. Here is an example:

.ocp-example.rc
----
GUID=testocp35
REGION=eu-central-1
KEYNAME=gucore
ENVTYPE=ocp-workshop
SOFTWARE_TO_DEPLOY=openshift
HOSTZONEID=Z3IHLWJZOU9SRT
ENVTYPE_ARGS=(
-e osrelease=3.5.5.31
-e "bastion_instance_type=t2.large"
-e "master_instance_type=c4.xlarge" 
-e "infranode_instance_type=c4.4xlarge"
-e "node_instance_type=c4.4xlarge"
-e "nfs_instance_type=m3.large"
-e "subdomain_base_suffix=.example.opentlc.com"
-e "node_instance_count=1"
-e own_repo_path=http://admin.example.com/repos/ocp/3.5
-e repo_version=3.5
)
----

It has several possible actions as second arg:

. provision
. destroy
. stop
. start

.Example run
----
$ cd scripts
$ ./wrapper.sh ocp-workshop-3.5.rc provision
