This tutorial explains how to manually build and push an image to Docker Hub. As an example, we will build a Docker image for a simple Node.js application that has basic CI tests as well as code coverage reports. The Dockerfile is a part of the application repository on Github.

This tutorial explains how to create a kubeconfig file to authenticate to a self-hosted Kubernetes cluster. If you use a hosted solution like GKE or AKS, you get the benefit of the cloud provider's Auth system. If it is self-hosted, then you'll have to take the DIY approach. This guide helps you to create a service account on Kubernetes and create a kubeconfig file that can be used by kubectl to interact with the cluster.

This tutorial explains how to manually provision a AWS Virtual Private Cloud(VPC) using Terraform. Before you start, you should be familiar with the following concepts:

• AWS VPC
• Terraform aws_vpc
• Terraform aws_internet_gateway
• Terraform aws_subnet
• Terraform aws_route_table
• Terraform aws_route_table_association
• Terraform aws_security_group

The best way to get started is to install Terraform and run scripts on your local machine to provision a VPC. The first section of this tutorial explains how to do that. However, manual execution isn't the best and most efficient way to run Terraform scripts, so we will take a look at the challenges and learn how to automate this workflow. 

This tutorial explains how to manually provision a AWS Virtual Private Cloud(VPC) using Ansible. Before you start, you should be familiar with the following concepts:

• AWS EC2
• Ansible overview
• Ansible vpc module

The best way to get started is to install ansible and run playbooks manually on your local machine to provision a VM. The first section of this tutorial explains how to do that. However, manual execution isn't the best and most efficient way to run ansible playbooks, so we will take a look at the challenges and learn how to automate this workflow with a step-by-step tutorial.
