Extend Ambari

Introduction

Hortonworks wrote a great article how to add new components into Amabri:

https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=38571133

Unfortunately, this document is not enough if you really want to add your own component.

Checking the State of Your States

If applicable, make sure your design component accounts for all these states. This is basically copied from the Nine States of Design Medium article. 😛

Initial state: What happens before your component does anything? Maybe it’s the first time a user sees it. Maybe it’s not activated yet. Essentially, the component exists but hasn’t started.
Loading state: Have you accounted for when a user will be waiting for something to happen? What does that look like?
Empty state: Your component has initialized, but it’s empty. No data. No Items. Now may be a good time to get the user to act (“Do this thing!”), or to reward them (“Good job, everything is taken care of”).
One state: You have some data. On an input, this may be after the first keystroke. In a list, it might be when you have one item (or one left).
Some data state: This is usually what you think

Enable #enable-devtools-experiments flag in chrome://flags section.
Open Chorme Devtools and check Settings > Experiments > Allow extensions to load custom stylesheets.

Create the following four files in a dedicated folder.

3.1. devtools.html

<html>
<head></head>
<body><script src="devtools.js"></script></body>

Last tested version: 5.7.20

0. Preparation

Make sure LXC has more than 12GB, otherwise Unifi fails to start!

1. Follow steps from Ubiquiti site

# for unifi
echo 'deb http://www.ubnt.com/downloads/unifi/debian stable ubiquiti' | sudo tee /etc/apt/sources.list.d/100-ubnt-unifi.list

	function string_to_slug (str) {
	str = str.replace(/^\s+\|\s+$/g, ''); // trim
	str = str.toLowerCase();

	// remove accents, swap ñ for n, etc
	var from = "àáäâèéëêìíïîòóöôùúüûñç·/_,:;";
	var to = "aaaaeeeeiiiioooouuuunc------";
	for (var i=0, l=from.length ; i<l ; i++) {
	str = str.replace(new RegExp(from.charAt(i), 'g'), to.charAt(i));
	}

	#!/bin/bash
	#
	# git get
	#
	# Place this script in your path, so that git(1) can find it. Presto!
	# You can now type `git get` instead of `git pull` and enjoy the
	# advantages of rebasing atop instead of merging remote changes.
	#
	# If you have local changes, use `git get --stash` to stash and
	# pop afterwards your changes automatically.

	#! /bin/bash
	# Usage:
	# ./git-move.sh path/to/file/or/dir path/to/destination/repo
	echo "creating patch for path ${1}"
	git log --name-only --pretty="format:" --follow "${1}" \
	\| sort -u \| \
	xargs git log --pretty=email --patch-with-stat --reverse --full-index --binary -m --first-parent -- > "${2}/_patch_" \
	&& echo "moving to destination repo at ${2}" \
	&& cd "${2}" \
	&& echo "applying patch" \

	# Instructions for installing Pi-hole 4.2 on UniFi CloudKey Gen 1 (UC-CK) running firmware 0.13.6
	# Pi-hole will need to be completely re-installed after every FW update or if CloudKey is reset to defaults.

	# Verify UC-CK is running firmware v0.13.6 (or later) before installing Pi-hole. If not, do:
	ubnt-systool fwupdate https://dl.ubnt.com/unifi/stage/cloudkey/firmware/UCK/UCK.mtk7623.v0.13.6.7ad551e.190225.0939.bin

	# UC-CK firmware v0.13.6 downgrades UniFi Controller to 5.10.17. Upgrade to 5.10.19 with:
	cd /tmp
	wget https://dl.ubnt.com/unifi/5.10.19/unifi_sysvinit_all.deb
	dpkg -i unifi_sysvinit_all.deb
