You have to do 2 things in order to allow your container to access your host's postgresql database

Make your postgresql listen to an external ip address
Let this client ip (your docker container) access your postgresql database with a given user

Obs: By "Host" here I mean "the server where docker is running on".

Make your postgresql listen to an external ip address

Find your postgresql.conf (in case you don't know where it is)

$ sudo find / -type f -name postgresql.conf

Sometimes we need to share props and behaviour between multiple components/containers. For that we can do a higher order component. Example:

Higher Order Component that will decorate other component:

	# Assuming you're a regular user that has doas allowances for vmctl
	mkdir -p ~/vmm
	cd ~/vmm

	# Grab the the one of the virt iso's of Alpine Linux
	curl https://nl.alpinelinux.org/alpine/v3.6/releases/x86_64/alpine-virt-3.6.0-x86_64.iso -o alpine-virt-3.6.0-x86_64.iso

	# Make a new virtual disk image, change the size as needed
	vmctl create alpine-virt.img -s 6G

	#!/bin/bash

	if [ -z "$VERSION" ]; then
	echo 'Please specify a version. e.g, "VERSION=3.8.5 sh install-python-alpine.sh"'
	exit
	fi

	export PYTHON_DOWNLOAD_URL=https://www.python.org/ftp/python/$VERSION/Python-$VERSION.tgz

	sudo apk update

	log4j.debug=false

	# Default level is INFO
	log4j.rootLogger=INFO,StdoutErrorFatal,StdoutWarn,StdoutInfo,StdoutDebug,StdoutTrace

	# and for com.some.package.* log everything
	log4j.logger.com.some.package=TRACE

	log4j.appender.StdoutErrorFatal=org.apache.log4j.ConsoleAppender
	log4j.appender.StdoutErrorFatal.layout=org.apache.log4j.PatternLayout

	#remember to edit the .template/openbsd.conf to set the correct version.

	pkg install vm-bhyve
	zfs create pool/vm
	echo 'vm_enable="YES"' >> /etc/rc.conf
	echo 'vm_dir="zfs:pool/vm"' >> /etc/rc.conf
	vm init
	cp /usr/local/share/examples/vm-bhyve/* /mountpoint/for/pool/vm/.templates/
	vm switch create public
	vm switch add public em0

	// How to Use raw H.264 (Simulated RTSP)
	// 1. Start with `node ffmpegToWeb.js`
	// 2. Get the IP address of the computer where you did step 1. Example : 127.0.0.1
	// 3. Open VLC and "Open Network Stream".
	// 4. Input the following without quotes : `http://127.0.0.1:8001/h264` and start.
