docker run -it --rm --privileged --pid=host justincormack/nsenter1

Virtual hosts

Let's say you want to host domains first.com and second.com.

Create folders for their files:

Tabs and Windows

Function	Shortcut
New Tab	`⌘` + `T`
Close Tab or Window	`⌘` + `W` (same as many mac apps)
Go to Tab	`⌘` + `Number Key` (ie: `⌘2` is 2nd tab)
Go to Split Pane by Direction	`⌘` + `Option` + `Arrow Key`
Cycle iTerm Windows	`⌘` + `backtick` (true of all mac apps and works with desktops/mission control)

Tambahkan list di bawah ke /etc/hosts.

	# download ubuntu-cloud image
	# NOTE: ubuntu-server won't properly work with cloud-init for some reason
	wget https://cloud-images.ubuntu.com/focal/current/focal-server-cloudimg-amd64.img

	# NOTE: no need for sudo because we already login as root

	# install image customization tool
	apt update -y && apt install libguestfs-tools -y

	# install qemu-guest-agent inside of image

	#!/bin/sh
	set -e
	set -o noglob

	# Usage: ./install.sh [options]
	#
	# Example:
	# Installing on first master node run:
	# ./install --num 3 --vip 192.168.2.10 --iface eth0
	# Installing on other master nodes run:

	Add the `replication` section to the mongod.conf file:

	destination: file
	path: /usr/local/var/log/mongodb/mongo.log
	logAppend: true

	$ docker-machine ls
	NAME ACTIVE URL STATE URL SWARM DOCKER ERRORS
	default * virtualbox Running tcp://192.168.99.100:2376 v1.9.1

	# Note the host URL 192.168.99.100 - it will be used later!

	# Build an image from current folder under given image name
	$ docker build -t gleb/demo-app .
