15 - XMonad and Xmobar

From a fresh installation of Ubuntu 20.04 (ubuntu-20.04.2.0-desktop-amd64.iso), install the base XMonad package, extra libraries/modules from the community as well as xterm and dmenu with:

sudo apt install xmonad libghc-xmonad-contrib-dev xterm dmenu

Log out, click your user, select XMonad from the cog at the bottom right and type your password to log in using XMonad instead of the default window manager. The black screen you get is suckless to the extreme and completely expected :-) No wallpaper, no menu, no panel...

Compile Apache MiNiFi 0.4.0 C++ for alpine-based image on Raspberry Pi 3.

# ----- Instantiate an immutable Debian container for compilation ----- #
# Bind mount a shared volume to store the binary once it is built.
docker run -it --rm -v `pwd`:/build resin/raspberrypi3-debian /bin/bash

# ----- Inside the Debian container ----- #
apt update && apt install git build-essential
git clone https://github.com/apache/nifi-minifi-cpp

Elastic does not provide Filebeat binaries for ARMv7. Luckily, Filebeat can easily be cross-compiled with:

# ----- Instantiate an immutable Go container for cross-compilation ----- #
mkdir build && cd $_
docker run -it --rm -v `pwd`:/build golang:1.9 /bin/bash

# ----- Inside Go container ----- #
go get github.com/elastic/beats
cd /go/src/github.com/elastic/beats/filebeat/

	cd ~/.local/bin
	docker run -v $(pwd):/software sethvargo/hashicorp-installer terraform 0.12.28
	docker run -v $(pwd):/software sethvargo/hashicorp-installer vault 1.4.3

	# Then make sure ~/.local/bin is added to $PATH in .profile, .bashrc or .zshrc

	/*
	Usage:
	$ tfenv install 0.12.19
	$ tfenv use 0.12.19
	$ terraform init
	$ terraform plan
	$ terraform apply -auto-approve
	$ terraform destroy

	- La carte Ethernet n'est pas reconnue pendant l'installation.
	- La procédure 12.04 ne fonctionne pas. Dû à l'architecture x64 ?
	- Les outils WiFi ne sont pas installés par défaut.

	=> impossible de se connecter. Partir d'une 14.04, configurer le WiFi et faire l'upgrade vers 16.04 manuellement.

	Ensuite, suivre les instructions de ce billet pour activer l'interface `p*p1` (anciennement eth0) : https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1310798
