Workshop Info

This repository contains materials for workshop "Start using Kubernetes as Developer in 6h".

Workshop is dedicated to software developers with no or little knowledge about Kubernetes. However, basic familiarity with containerization and Docker is expected.

Atendees are asked to bring their own laptops with prepared environment according to instructions enclosed in section below.

Local envorionment setup

1. Setup connection to some kubernetes cluster with kubectl

You can do this by:

• Installing locally minikube instructions
• Buying kubernetes cluster subscription on one of cloud providers (e.g. azure, google cloud, aws ) and configuring connection to remote cluster according to instructions provided provider's page

Verify that the setup is correct, by

A. Checking cluster connectivity

kubectl cluster-info

You should get similar output:

Kubernetes master is running at https://172.17.85.7:8443
KubeDNS is running at https://172.17.85.7:8443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy

B. Checking connectivity from cluser to Docker Hub

Run in console:

kubectl run my-httpd --image=httpd --port=80 --restart=Never

Then following command will try to download httpd docker image from public registry your cluster. After while, a run of following command:

kubectl get pods

should return output similar to:

NAME                        READY   STATUS    RESTARTS   AGE
my-httpd                    1/1     Running   0          24s

C. Checking port-forward functionality

Check if you can forward port of application running on Kubernetes to your localhost, and access it via browser.

Run in console:

kubectl port-forward my-httpd 9999:80

And then open in browser localhost:9999. You should get a page with "It works!" message.

2. Install docker

Install docker on your local machine accoring to instructions on docker page
