Workshop: Kubernetes fundamentals

Introduction

This workshop demonstrates how to deploy / manage dockers applications in GKE. There is REST API Spring Boot integrated to a MongoDb. In addition, there is an Angular App that will display a contact list. The REST API, MongoDb and Angular app will be docker containers.

Why build Docker + GKE?

• Open-source
• GKE and Docker Work Well Together.
• K8s has been working with GKE since day one, which makes certain things simple to do together.
• Great for modern cloud-based apps, such as web apps, IoT apps, and mobile backends.

Prerequisites

• Install Visual Studio (Mac OS / Linux / Windows).
• Install Docker Desktop.
• Create an GCP Account.
• Download and configure gcloud command -> https://cloud.google.com/sdk/install
• Initializing Cloud SDK -> https://cloud.google.com/sdk/docs/initializing
• Install kubectl (It depends on which OS you use)

How to use it

• Download or clone the project.

• gcloud auth login

• gcloud config set project <PROJECT_ID>

• gcloud config set compute/zone us-central1

• gcloud container clusters create taller-k8s
  --num-nodes 2
  --machine-type n1-standard-1

• gcloud container clusters get-credentials taller-k8s

• kubectl apply -f kube-deployment.yml

• gcloud container clusters delete taller-k8s (Optional. It when you want to delete your K8s cluster)
