Whanos

Wha- what is this name?

It's MCU's Thanos as a Whale. I guess because Whales and Containers are intimally connected, and that Thanos can do lot's of stuff with a single snap.

(Don't ask me, I did not come up whis this somewhat meaningfull though quite particular name. If you like it, you can try to join Epitech's pedagogical team, you'd probably have a blast)

What it can do

This project can automatically build and deploy containers on a kubernetes cluster from a git repository.

Supported languages / detection trigger file:

javascript / package.json
C / Makefile
Java / pom.xml
befunge / main.bf
python / requirements.txt

If /whanos.yml is found, the containers will be deployed on the cluster

Accessing deployed Apps

Deployed apps naming follows this pattern: "GITHUB_USER-REPO-BRANCH_NAME"

The app will be available at https://APP_NAME.k8.YOUR_DOMAIN/

Ports defined in whanos.yml will be forwarded respectively to the cluster's port.

HTTPS traffic (port 443) is forwarded to container port 80

Default standalone apps will have container port 80 exposed

LIMITATIONS: supported branch names must match domain name naming convention, for example no "@", "/", etc

Deployment

I have no infrastructure

Required:

Terraform
A digital ocean account
A domain name that belongs to you and is managed by digital ocean
Python
Ansible

Steps:

Copy .env.example to .env and fill it with your info
adapt or delete the cloud seting in terraform/provider.tf to match your cloud or to save the infrastructure state locally
install python requirements with pip3 install -r requirements.txt
run ./deployment.sh create
install doctl and run doctl auth init

This will create 3 resources

A docker container registry at registry.DOMAIN_NAME
A jenkins instance at jenkins.DOMAIN_NAME
A kubernetes cluster

I have infrastructure
