vagrant was created during the setup of the VM. We modify it a little bit so it looks like the following : # -*- mode: ruby -*-Ĭonfig.vm.provision “shell”, inline: mtu 1500 qdisc fq_codel state UP group default qlen 1000 This generates a file called Vagrantfile which defines how the virtual machine should be setup. In a new folder, we run the following command : $ vagrant init ubuntu/bionic64 We use Vagrant, a great tool from Hashicorp, to provision and configure a local virtual machine on VirtualBox. We will start by creating a new Docker Host and make sure it runs the latest Docker version. Docker 18.09 makes it possible ! Let’s test it. This port needs to be opened in the security groups (and restricted to a white list of IP addresses if possible) so a remote client can access the daemon.Īs ssh is widely used and is often one of the protocols allowed by default, it could be convenient to access the Docker daemon directly via ssh. -H tcp://0.0.0.0:2376 makes the daemon available via any network interface on port 2376.Locally, the Docker client uses this socket to communicate with the daemon -H unix://, refers to the local unix socket /var/run/docker.sock.There are 2 important flags related to the client / server communication here: –tlskey=/var/lib/boot2docker/server-key.pem usr/local/bin/dockerd -g /var/lib/docker Below is a typical example of options provided to the Docker daemon at startup. The Docker client communicates usually with the daemon either locally, via the unix socket /var/run/docker.sock, or over a network via a tcp socket.
