如何将在本地计算机上运行的数据库服务器作为服务连接到托管在关键云铸造厂上的Web应用程序？

Question

I am trying to test run a basic .NET web application on pivotal cloud foundry. This web application uses as its database a MongoDB server hosted on my local machine. At the moment I am limited to use of the cloud infrastructure by using just the Apps Manager.

I have read the pivotal cloud foundry docs about user provided services, but cannot figure out as to how the connection is to be really made. I have already come across various other ways like using MongoDB as a service (beta version), but at the moment I am not allowed access to the Operations Manager. Looking for an explanation on user provided services or how to implement the service broker API, specifically.

I am new to Mongo as well, so any suggestion regarding making a connection through tweaking Mongo may help as well. Thanks

Answer 1

The use case you describe (web app in PCF connecting to a resource in your local machine) is not recommended.

You can create a MongoDB instance for development purposes in PCF.

$ cf marketplace  
...  
mlab    sandbox       Fully managed MongoDB-as-a-Service  
...  

You can create a mlab service and bind it to your application. You will then have a MongoDB instance in PCF that you can use for development purposes.

Edit:
In that case a user provided service might help you, where you pass in your remote MongoDB instance configuration that you can read in your application. eg:

cf.exe cups my-mongodb -p '{"key1":"value1","key2":"value2"}'

Answer 2

You can add your local mongo-db as a CUPS service to your PCF Dev.
