In Bluemix I have a container running an instance of MongoDb. I would like to connect to the MongoDb from a Node.js CF application. Do I really have to assign a public IP address to the container to do this? Can I use the Bluemix VPN service to create a tunnel to the container?
You will not be able to reach an IBM Container from a Bluemix application using the private container IP, since the environments are in different networks. The Bluemix VPN service is used to provide secure connectivity between your Bluemix resources and your on-premises data center. It allows to securely access IBM containers via private IP, but you need an IPSec VPN gateway at your data center or SoftLayer server to form a secure connection with that service.
