Found the issue. Actually, our setup did install Docker 1.12 ! Thats why --hostname create this issue. Actually, I can't find how we install Docker in our setup ...
In the bash-script, I do: curl -sSL https://get.docker.com/ | sh
Here is what this script is doing:
apt-get update -qq
apt-get install -y -qq apt-transport-https ca-certificates curl software-properties-common
curl -fsSL "https://download.docker.com/linux/ubuntu/gpg" | apt-key add -qq
echo "deb [arch=amd64] https://download.docker.com/linux/ubuntu xenial edge" > /etc/apt/sources.list.d/docker.list
apt-get update -qq
apt-get install -y -qq docker-ce
