# Intro
|
|
|
|
We created this set of exercises to give you the opportunity to express yourself technically. Do as much as you can in
|
|
the time you have. Feel free to ask us questions, if any. No worries if you can't make it all by lack of time or
|
|
understanding of what we're asking. We'll defrief it with you during our next call.
|
|
|
|
**Have fun!**

## Fork
|
|
|
|
Fork this repo to your own github repo
|
|
|
|
# Ex. 1 - python
|
|
|
|
This exercise will be split into multiple smaller ones. For each one
|
|
you can create files named `a.py`, `b.py` and `c.py`. You maybe resuse the same
|
|
environment for all sub-exercises
|
|
|
|
Guidelines:
|
|
- Use python version python3.7+.
|
|
- Unless specified otherwise you can only use builtin modules.
|
|
|
|
### python - A
|
|
|
|
Write a script that prints out whatever text input is passed as argument
|
|
|
|
Example:
|
|
|
|
```
|
|
$ python a.py ping ping ping
|
|
ping ping ping
|
|
```
|
|
|
|
### python - B
|
|
|
|
Write a script take takes one argument (-t/--target) which can only
|
|
accept the following values `titi`, `toto`, `tata`. When called with a valid
|
|
target, the script should print out the target text to stdout (`titi`, `toto` or `tata`).
|
|
When an invalid target is provided an error message should be printed to stderr
|
|
|
|
Example:
|
|
|
|
```
|
|
$ python b.py --target titi
|
|
titi
|
|
|
|
$ python b.py -t tutu
|
|
usage: b.py [-h] [-t {titi,toto,tata}]
|
|
b.py: error: argument -t/--target: invalid choice: 'tutu' (choose from 'titi', 'toto', 'tata')
|
|
```
|
|
|
|
### python - C
|
|
|
|
Write a script that creates ascii art equivalent of text passed as argument.
|
|
For this exercise you may use a 3rd party module.
|
|
|
|
Example:
|
|
|
|
```bash
|
|
$ python c.py 'Hello buddies'
|
|

|
|
|
|
```
|
|
|
|
# Ex. 2 - docker
|
|
|
|
In ex2 folder, you will find a `plik` binary (taken from https://plik.ovh).
|
|
|
|
Can you build very lighweight docker image that contains ONLY `plik` binary, and that execute `plik` by default?
|
|
|
|
Push your Dockerfile in the ex2 folder.
|
|
|
|
# Ex. 3 - terraform
|
|
|
|
In ex3 folder, you will find an incomplete `openrc` file.
|
|
|
|
You will need to amend the file to configure the correct `OS_USERNAME` and `OS_PASSWORD` with the one that we gave to you.
|
|
|
|
Then, using `terraform`, can you write a plan to boot a `d2-4` on `GRA7` region with a floating IP.
|
|
|
|
Bonus, on that instance, make sure a web server (`nginx`) is running.
|
|
|
|
Push your `main.tf` file in ex3 folder.
|
|
|
|
# Ex. 4 - git
|
|
|
|
In this repo, there are two branches:
|
|
|
|
- stein
|
|
- queens
|
|
|
|
Stein contains the following commits:
|
|
|
|
- 1ff2641 (stein) G
|
|
- cf24853 F
|
|
- 3fcdfa0 E
|
|
- cb8c71a D
|
|
- 849ef26 C
|
|
- 372c155 B
|
|
- edc8ed7 A
|
|
|
|
Queens contains the following commits:
|
|
|
|
- 2624c16 (queens) F
|
|
- 5e3521b B
|
|
- edc8ed7 A
|
|
|
|
So the common ancestor is A (same commit ID).
|
|
|
|
B has been cherry-picked from stein to queens, without conflicts.
|
|
|
|
F has also been cherry-picked but with conflicts (solved, of course).
|
|
|
|
## Exercice
|
|
|
|
You will need to create two branches:
|
|
|
|
- merged
|
|
- rebased
|
|
|
|
### Merged
|
|
|
|
Create the merged branch first:
|
|
|
|
```bash
|
|
git checkout -b merged origin/queens
|
|
```
|
|
|
|
Then merge the stein branch into your branch
|
|
|
|
```bash
|
|
git merge origin/stein
|
|
```
|
|
|
|
You will have a conflict to solved.
|
|
|
|
Solve it, then push your `merged` branch to your repo.
|
|
|
|
### Rebased
|
|
|
|
Now create the rebased branch:
|
|
|
|
```bash
|
|
git checkout -b rebased origin/queens
|
|
```
|
|
|
|
Now rebase it on top of stein:
|
|
|
|
```bash
|
|
git rebase -i origin/stein
|
|
```
|
|
|
|
You will have a conflict to solved.
|
|
|
|
Solve it, then push your `rebased` branch to your repo.
|
|
|
|
## Check diff
|
|
|
|
Now check the diff between your two branches `merged` and `rebased`.
|
|
|
|
```bash
|
|
git diff merged..rebased
|
|
```
|
|
|
|
Can you explain why you have a diff?
|
|
|
|
Write down the explanation in ex4 folder (like in a `README.md` file)
|
