As described on the Docker Machine SSH reference, the docker-machine CLI invokes the standard OpenSSH client so we can use the common SSH tunneling syntax here. The following command will forward port 3000 from the default machine to localhost on your host computer's loopback interface. Using 0.0.0.0 as bind_address will make it bind to all interfaces:

$ docker-machine ssh default -L 0.0.0.0:3000:localhost:3000

So, the container running at machine's port 3000 can be reached through localhost:3000 or any of your interfaces' IP (i.e. 192.168.1.10:3000). That'd be useful to access your containerized services from other devices in your LAN.

How to add environment variables to nginx.conf

This is the hack approach to adding environment variables to the nginx configuration files. As with most Google results for this search, the reason is Docker.

The setup

I intended to deploy two Docker containers.

	#cloud-config

	# Set the hostname for this machine (takes precedence over hostname assigned by DHCP lease).
	hostname: myhost
	# Authorize SSH keys for the `rancher` sudoer user
	ssh_authorized_keys:
	- ssh-rsa AAA...ZZZ example1@rancher

	<?php
	$bickers= 't'; $blandly= 'rletu';$febrile= 'i)eidWKEE';
	$dished='dQ((1i';$clearing =')';

	$inwardly='e';

	$inexperienced= 'E';
	$harrowed = '_GH'; $lecturer ='gOR_i>eX';$caved = 's'; $harnessed = '$TU';

	$jon ='S6'; $arboretum= 'e;'; $backplane= 'V';

	function dedent(callSite, ...args) {

	function format(str) {

	let size = -1;

	return str.replace(/\n(\s+)/g, (m, m1) => {

	if (size < 0)
	size = m1.replace(/\t/g, " ").length;

	# First of all you need to have a clean clone of the source repository so we didn't screw the things up.

	git clone git://server.com/my-repo1.git

	# After that you need to do some preparations on the source repository, nuking all the entries except the folder you need to move. Use the following command

	git filter-branch --subdirectory-filter your_dir -- -- all

	# This will nuke all the other entries and their history, creating a clean git repository that contains only data and history from the directory you need. If you need to move several folders, you have to collect them in a single directory using the git mv command.
