Enable Docker Remote API with TLS client verification

Docker's Remote API can be secured via TLS and client certificate verification.
First of all you need a few certificates and keys:

CA certificate
Server certificate
Server key
Client certificate
Client key

Create certificate files

Run commands on remote Docker host

This is how to connect to another host with your docker client, without modifying your local Docker installation or when you don't have a local Docker installation.

Enable Docker Remote API

First be sure to enable the Docker Remote API on the remote host.

This can easily be done with a container.
For HTTP connection use jarkt/docker-remote-api.

curl -sfL https://get.k3s.io | sh -
# get token
cat /var/lib/rancher/k3s/server/node-token

Install k3s on worker nodes as agents:

	# Install QEMU OSX port with ARM support
	sudo port install qemu +target_arm
	export QEMU=$(which qemu-system-arm)
