DNS name for auth_url in provision.tfvars causes error in remote provision.sh

[metahertz]

If using a DNS name rather than an IP address for auth_url in terraform.tfvars , the make provision stage of the install will fail.

The error occurs in the remote (bastion) execution of provision.sh with this line, that expects an IP address to grep out of the OS_AUTH_URL var, and results in an empty OPENSTACK_IP= statement if passed a DNS name instead, which fails the script.

IE:
OS_AUTH_URL="https://1.2.3.4:5000/v2.0" #works
OS_AUTH_URL="https://amsterdam.cloud.somewhere.com:5000/v2.0" #fails as below

Also worth noting that with a HTTPS openstack API's, an IP address (as needed above) will never verify with the server address in openssl, so the following Excon statement is needed before initialising an Excon.new instance for the bosh_workspace setup, allowing SSL verification to be ignored. (Workaround), best solution to support DNS name as above.

        params.merge!(:persistent => params.fetch(:persistent, persistent))
        params[:headers]["User-Agent"] ||= user_agent
        Excon.ssl_verify_peer = false #This
        @excon = Excon.new(url, params)
