Many companies use Jenkins as their automation server of choice. and use Docker as their preferred way to ship their applications.
CI/CD becoming a more popular thing every day due to the worldwide promotion of DEVOPS I wanted to create a simple tutorial where we put these two technologies together and see if we can arrange a beautiful marriage.

FASE 1

cfdisk /dev/sda

label type: gpt
delete all partitions

Mount point	Partition	Partition type (GUID)	Bootable flag	Suggested size
/boot	/dev/sdx1	EFI System Partition	Yes	260–512 MiB
[SWAP]	/dev/sdx2	Linux swap	No	More than 512 MiB
/	/dev/sdx3	Linux	No	Remainder of the device

SWAP Recommandations

Amount of RAM in the system	Recommended swap space	Recommended swap space if allowing for hibernation
⩽ 2GB	2 times the amount of RAM	3 times the amount of RAM
> 2GB – 8GB	Equal to the amount of RAM	2 times the amount of RAM
> 8GB – 64GB	At least 4 GB	1.5 times the amount of RAM
> 64GB	At least 4 GB	Hibernation not recommended

 

Resulting for our system in:

sda1 512MB [EFI System]
sda2 2GB [Linux swap]
sda3 Remainder [Linux filesystem]
MAKE NOTE OF THE PARTUUID OF sda3, WE WILL NEED THIS LATER!

BE AWARE, USE LOWER CASE PARTUUID OF EARLIER NOTED PARTUUID, otherwisde it will not work!

pacman -S bash-completion
exit

FASE 3

Login as wouter!

sudo pacman -Syyu
sudo pacman -S reflector
sudo reflector -l 100 -f 50 -c NL -c BE -c DE --sort rate --threads 5 --verbose --save /tmp/mirrorlist.new

sudo pacman -Syu 

FASE 4

Login as wouter!

sudo pacman -S openssh
systemctl start sshd.service
systemctl enable sshd.service

FASE 5 – Install nome

sudo pacman -Syyu
sudo pacman -S gdm gnome virtualbox-guest-utils
systemctl enable gdm.service
sudo reboot now

FASE 6 – Install yaourt

sudo pacman -S --needed base-devel git wget yajl
git clone https://aur.archlinux.org/package-query.git
cd package-query/
makepkg -si

cd ..

cd ..
sudo rm -dR yaourt/ package-query/

FASE 7 – Install pamac

yaourt -S pamac-aur

Or we can keep it very simple end just install X
