## Notes to myself
|
||||
|
||||
* Notes in ungleich-marketing.org / Quiz
|
||||
|
||||
## Objective
|
||||
|
||||
This codebase is for preparing the ungleich game, which heavily relies
|
||||
on checking other people's VMs.
|
||||
|
||||
The (not so) hidden objective is to create the base for "cmon",
|
||||
our new monitoring system that does not suck.
|
||||
|
||||
### Planned features (monitoring)
|
||||
|
||||
- full parallel execution
|
||||
- history support -> possible grafana interface
|
||||
- easy to create and extend checks
|
||||
- Requirements: python3 + binaries for certain checks
|
||||
- Minimal core logic - checks can check "anything"
|
||||
|
||||
### Planned features (game)
|
||||
|
||||
- Allow registration
|
||||
- Allow deep (i.e. functionality based) checks of services
|
||||
- Define points (or monitoring severity)
|
||||
|
||||
|
||||
## Welcome to the ungleich-game, a geek game engine!
|
||||
|
||||
ungleich-game is supposed to be an easy-to-use, easy-to-play and
|
||||
easy-to-extend game framework for geeks. The project name is
|
||||
ungleich-game, as it has its roots at ungleich - the project name
|
||||
might change later.
|
||||
|
||||
## How to play
|
||||
|
||||
### Monitoring
|
||||
* Select a game server
|
||||
* Register
|
||||
* List challenges - have fun!
|
||||
|
||||
Test base:
|
||||
### How to play on Nico's notebook
|
||||
|
||||
1. Register
|
||||
|
||||
```
|
||||
python check-cli.py
|
||||
curl -d user=nico http://nico.ungleich.cloud:5002/register
|
||||
```
|
||||
|
||||
### Game (not implemented)
|
||||
2. Get challenges
|
||||
|
||||
ungleich register --name your-user-name --email your@email
|
||||
--first-name Yourfirstname --last-name YourLastName
|
||||
```
|
||||
curl http://nico.ungleich.cloud:5002/challenge
|
||||
```
|
||||
|
||||
ungleich play-game --game register --ip
|
||||
ungleich play-game --game dns-forward --ip
|
||||
3. Get a challenge description
|
||||
|
||||
## Documentation
|
||||
```
|
||||
curl http://nico.ungleich.cloud:5002/challenge/registernet
|
||||
```
|
||||
|
||||
- Raise CheckException on parameter wrong
|
||||
4. Solve a challenge
|
||||
|
||||
## How to write a check
|
||||
```
|
||||
curl -d user=nico -d 2a0a:e5c0:101::/64 http://nico.ungleich.cloud:5002/challenge/registernet
|
||||
```
|
||||
|
||||
- Your command must return with exit code = 0
|
||||
- Output will be saved by cmon, but not interpreted
|
||||
5. Get high score
|
||||
|
||||
## TODOs
|
||||
```
|
||||
curl http://nico.ungleich.cloud:5002/highscore
|
||||
```
|
||||
|
||||
- last result: select checkname where result = true
|
||||
- last success: select checkname where result = true
|
||||
|
||||
## Overview - Game flow
|
||||
|
||||
* Users register at a game server
|
||||
* Users play by getting challenges from the game server
|
||||
* Users can see their or all high scores on the main page
|
||||
|
||||
## Overview - Development Flow
|
||||
|
||||
[not yet fully implemented]
|
||||
|
||||
The idea is that there are challenges and each challenge offers:
|
||||
|
||||
* A description
|
||||
* Some dependencies (on something another challenge can provide)
|
||||
* A score ("how difficult it is")
|
||||
|
||||
### How to add challenges
|
||||
|
||||
* Create challenges-<YOURNAME>.py and add challenges in there
|
||||
* Do some magic so all challenges are imported by server
|
||||
|
||||
## Overview - Security
|
||||
|
||||
None at the moment.
|
||||
|
||||
|
||||
## Tech stack
|
||||
|
||||
The base for building games is:
|
||||
|
||||
* Python3 - The programmming language
|
||||
* Flask - web frontend
|
||||
* etcd - storing data, games, etcd.
|
||||
|
||||
## Things to solve
|
||||
|
||||
* Enhance the Challenge class - maybe make it easier for challenges to abort
|
||||
* Enhance the Challenge class - abstract away writing information?
|
||||
* Implement dependencies / providers for challenges
|
||||
* Add an easy to use CLI (Steven might like click)
