OpenShift 3.11 deployment fails with unexpected EOF while looking for matching `''

[amitlib]

Describe the bug
Trying to deploy OCP 3.11 on existing vnet with template from 03/18/2019.
On the bastion node I can see that deployOpenShift.sh fails with error:

/bin/sh: -c: line 0: unexpected EOF while looking for matching `''
/bin/sh: -c: line 1: syntax error: unexpected end of file

To Reproduce
Steps to reproduce the behavior:

1. Create parameters file with virtualNetworkNewOrExisting=existing
2. Created all the relevant secrets on Azure vault
3. run deployment:

az group deployment create -g rnd-ocp11-test2-rg --name ocp11-test2
--template-uri https://raw.githubusercontent.com/Microsoft/openshift-container-platform/master/azuredeploy.json
--parameters @./parameters.json --debug

Expected behavior
OCP 3.11 cluster will be created.

@amitlib Can you also provide the stdout?

[amitlib]

stdout is empty. Tried to deploy it again today and got the same error.

I debugged the deployOpenShift.sh script, and it looks like the

# Setting DOMAIN variable
export DOMAIN=`domainname -d`

doesn't return any value. When reviewing other clusters that we have with OCP 3.9-3.11 that are already running on Azure (up for a few months) , I do get a domainname.
