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.

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!

Here are some hany tricks!
A recently stepped over to Ubuntu as my daily driver on my work laptop.
Finding myself a little afraid to do stuff with it… because it is all new to me.
Gone is the comfort of years of experience in keeping my OS up and running.
Windows was the main OS i used for the last… 20 years or so.
Being a developer iḿ used to installing a bunch of tooling that will help me in my daily workflow.
Just installing all sorts of stuff without knowing what I’m doing is… risky.
Having to reinstall my laptop as a result of shitty choices i make is a expensive consequence that my clients wont accept.
So it’s time to create a safe playground for myself that will help me recover from stupid mistakes quickly.
The answer to this is visualization…
Having used VMWare for the last…. 15 years or so this was the first thing I thought of.
But why not look around if there is something better. if we already have to get accustomed to the changes in OS, why not take it to a whole new level.
Lets dive into Vagrant, Virtualbox and Docker!
