Create certificates with Docker

[Sengorius]

An attempt was made, using a docker container to create the necessary SSL certificates. This would be useful on a Windows system, where openssl is not installed. But the printf (generate.sh at line 44) statement on the docker command line is a problem. The current attempt was bound to commit 6db0be3 and used following idea:

local SYSTEM_HAS_OPENSSL=`command -v openssl`
if [[ "1" == "$?" ]]; then
    print_warning "Openssl seems not to be installed on this machine. Trying to install with docker."
    RSA_COMMAND=docker\ run\ --user\ "$(id -u):$(id -g)"\ -i\ -v\ "${CERTS_PATH}:/export"\ "${OPENSSL_IMAGE}"\ openssl
    CERTS_PATH=/export
fi

See generate.sh at line 20 for details.

Maybe someone else knows a solution for this?
