Docker Reference

This week (May 2017) I have been learning about Docker... Here is what I've learned so far.

The shortcut commands in brackets refer to functions/aliases I've set up in my dotfiles.

Installing Docker on Ubuntu

sudo apt-get install docker docker-compose

Setup Gitea on Raspberry Pi (3)

These instructions are based on this article: https://www.alexruf.net/2016/05/23/setup-gogs-git-service.html.

Setup Raspberry Pi with minimal Raspbian image. You need to connect to the HDMI port and set the following:

sudo raspi-config

There you need to enable the SSH server and you should change the hostname.

Update and install dependencies

apt-get update; apt-get upgrade

dphys-swapfile swapoff
dphys-swapfile uninstall

apt-get remove -y --purge wolfram-engine triggerhappy xserver-common lightdm sonic-pi minecraft-pi pigpio
apt-get autoremove -y

	#!/bin/bash

	# Save docker images
	ds() {
	docker images \| \
	cut -d ' ' -f 1 \| \
	tail -n +2 \| \
	xargs -t -n 1 -I {} -P 4 \
	sh -c 'docker save {} \| bzip2 > $(echo "{}" \| sed "s/^.*\///").tar.bz2'
	}

	var pattern = /(MOBI\|EPUB\|PDF( ?\(H.\))?\|CBZ)$/i;
	var pattern2 = /(Download)$/;
	var nodes = document.getElementsByTagName('a');
	var downloadCmd = '';
	for (i in nodes) {
	var a = nodes[i];
	if (a && a.text && pattern.test(a.text.trim())) {
