DevOps Workshop: Helm

In this workshop we will simulate an operation of two python services, on Kubernetes, using Helm and Docker.

Prerequisites

• kubectl (tested on v1.14)

• helm cli (tested on v2.12)

• docker engine

• Kubernetes environment (local, cloud, managed, on-prem, whatever v1.14) with nginx ingress controller

Docs:

• Timer

• Auth

• Docker build

• About the helm charts

• Deploy

Accessing the endpoint

After deployed, curl the ingress host you configured in auth helm chart (devops-ws.example.io):

$ # get human time
$ curl -X GET http://devops-ws.example.io/datetime/asia/jerusalem -H "k8s-ws: user_a"
{"body": {"datetime": "2020-06-22T21:15:11.804696+03:00"}}

$ # get epochtime time
$ curl -X GET http://devops-ws.example.io/epochtime/asia/jerusalem -H "k8s-ws: user_a"
{"body": {"epochtime": 1592849876}}
