nfsbroker can push to cf/249, diego/1.0.0, nfs-volume/1.0.6

[ron4git]

I am trying to push nfsbroker as cf app.
The app builds fine, and pushed to cf without problem. However, it failed to start with/without cf bind to postgresql service instantances.

cf logs nfsbroker --recent showing following error:

We have created an issue in Pivotal Tracker to manage this:

The labels on this github issue will be updated when the story is started.

Can you run cf env nfsbroker after binding the service and post the results here?

[julian-hj]

My guess is that this line in main.go is causing the issue:

*dbPort = fmt.Sprintf("%.0f", credentials["port"].(float64))

Probably the posgres release you are using serializes port as a string not a number. As an experiment, you could try changing it to:

*dbPort = credentials["port"]

And let us know if that fixes the issue. If so, then we probably need to add some type assertions to accept port as a string or a number.

After changed line 183 of main.go to
*dbPort = credentials["port"]
getting following error in building.

./main.go:183: cannot use credentials["port"] (type interface {}) as type string in assignment: need type assertion

[ron4git]

change line 183 of main.go to

*dbPort = credentials["port"].(string)

worked.

[julian-hj]

Very good, thanks for the feedback. We'll try to get a fix in for this case shortly.

[julian-hj]

Closing this as fixed. Please re-open if you still see the issue.
