 Create nsx_pipeline_config.yml based on a sample config file, e.g. https://github.com/vmware/nsx-t-datacenter-ci-pipelines/blob/master/sample_parameters/PAS_only/nsx_pipeline_config.yml for PAS environment, and place it under /home/concourse.

 Set CONCOURSE_URL to http://<host_ip>:8080 (host_ip is the IP address of the primary NIC of the VM running the container (example: 10.85.99.130); it is not the loopback address. Set EXTERNAL_DNS to the DNS server (it should be able to resolve the vCenter hostname, and public names e.g. github.com), and  IMAGE_WEBSERVER_PORT to the port number provided in the  nsx_pipeline_config.yml parameter nsx_image_webserver (recommendation: 40001).
