Problem with environment variable substitution in OpenShift templates

[joselsegura]

When you are deploying a service using insights-core-messaging in a OpenShift environment using templates, the ${VAR} environment substitution is taken by OpenShift itself and tries to find a VAR parameter into the template.

This problem can be solved using the form $VAR (without brackets), but I'm not sure how it will work with defaulting environment variables like ${VAR:default_value}.

I think you'll have to pick one: either let ICM do the substitution or use openshift templates. @jhjaggars thoughts here?

If you are deploying with k8s/openshift (and I'm pretty sure you will be), I'd just use the templates provided by that system.

I'm currently using the $VAR_NAME alternative (without brackets and without default value) and it works fine in Openshift.

Thank you for your answers
