> This was discovered when trying to launch the {{[nvcr.io/nvidia/tensorflow:19.08-py3|http://nvcr.io/nvidia/tensorflow:19.08-py3]}} image using the Mesos containerizer. This launch fails with
> {noformat}
> Failed to launch container: Failed to get WWW-Authenticate header: Unexpected auth-param format: 'realm="https://nvcr.io/proxy_auth?scope=repository:nvidia/tensorflow:pull' in 'realm="https://nvcr.io/proxy_auth?scope=repository:nvidia/tensorflow:pull,push"'
> {noformat}
> This is because the [header tokenization in libprocess|https://github.com/apache/mesos/blob/master/3rdparty/libprocess/src/http.cpp#L640] can't handle commas in quoted realm values.
