Invalid Registry Endpoint pushing docker image

I built a docker container with docker 1.0, and tried to push it to a private docker registry mapped to s3, but it gives me “invalid registry endpoint”.

docker push loca.lhost:5000/company/appname
2014/06/20 12:50:07 Error: Invalid Registry endpoint: Get http://loca.lhost:5000/v1/_ping: read tcp connection reset by peer

The registry was started following settings similar to the example (adding aws region), and does respond if I do a telnet localhost 5000.

    Ok, it was due to me specifying AWS_REGION (eu-west-1) and the registry service failing part way through startup.

    Taking that out, the registry server finishes initializing and starts listening on the port, and a curl request to the /_ping url returned a response.

    I was able to retrieve enough console information to debug this by putting the settings in a config.yml file, setting loglevel to debug, then have docker running the registry image passing the config file rather than calling directly as I did above.

    Docker will be the best open platform for developers and sysadmins to build, ship, and run distributed applications.
