Generate password in a k8s microservice

pwgen-ws

This is my attempt to create a microservice in python. This microservice is very simple, and is a proof of concept for "how to use K8S / Prometheus" in a CI/CD context.

Requirements

• A working K8S cluster (or minikube)
• A Drone-CI CI/CD setup
• A working Prometheus setup
• A oAuth2 external service for authorisation (wishlist)

Drone configuration

$ export DRONE_SERVER="https://drone.example.com"
$ export DRONE_TOKEN="qjSDi2lj19Lk6QZC046HzLRBsDfPVDjqpZqj3G60cbRJe06hYijeZNZzpkVelGj2W6DRrw4dKGj62uWVI4lMTEihuAkdfFne0TcYmfCwh8RcaREmNiU3s6jyCyk3aopS"
