Error "x509: failed to load system roots and no roots provided" when waiting on a https

[frnhr]

Running directly from the docker image, I'm getting an unexpected error:

$ docker run --rm jwilder/dockerize dockerize -wait https://www.google.com

Am I using it wrong?

Same here. The docs are missing how to provide the needed root certificates or how to skip cert validation.
