Could not read docker config json

Hi,
I've been trying to run collector in the standalone mode, for a local image, that I had pulled from dockerhub previously. However, I'm getting the following errors, about it being unable to read the docker config file. I get the same error if I try with the example given in collector --help.

Any ideas as to what am I missing? Also let me know, if there exists a mailing-list or something where asking this would be more appropriate.
Thanks!

Worked after docker login.

Thanks for reporting this. Ideally, collector's code should be modified a little so that it will no longer look for a docker config file if it's started in local.host mode.

Probably your .docker/config.json file is empty or stored in a keychain (in the case of mac) with the "credsStore": "osxkeychain". If the later is the case.

docker logout
Go to Docker -> Preferences -> General :: uncheck the checkbox "Securely store credentials.."
docker login
