Creating a Public SSL/TLS Certificate in AWS Certificate Manager

If you plan to make the communication of your site visitors to be secure by using HTTPS then you need to use Public SSL/TLS Certificate. You can do this by requesting for a Public Certificate via AWS Certificate Manager (ACM).

Below are the advantages of using Public SSL/TLS Certificate provided by AWS Certificate Manager.

  • No charges = Free.
  • Auto renew – No need to worry on expiring SSL/TLS Certificate. ACM Automatically does this for you.
  • Easy integration with Amazon Web Services (AWS) products such as CloudFront, Elastic Load Balancer, API Gateway and many more.

Check the step-by-step guide on how you can request a Public SSL/TLS Certificate for HTTPS access of your website/domain.

Requesting for a Public SSL/TLS Certificate

Login to AWS Console and head to AWS Certificate Manager.

Note: AWS Certificate Manager is a regional service, therefore make sure to be in the correct AWS Region. If you are new to AWS just select N. Virginia (us-east-1) as it is one of the cheapest regions.

On the AWS Certificate Manager page, click on Get started.

On the next screen, make sure to select the Request a public certificate, then click on Request a certificate.

Under Add domain names. Enter the following.

*.[Your Domain]
Example:
*.chargedneutron.com
The * represents a wildcard. This will allow you to use the SSL Certificate to any subdomains that you want like www.domain.com, images.domain.com, sites.domain.com, mobile.domain.com
[Your Domain]
Example:
chargedneutron.com
Apex Domain or Naked Domain Name. Your domain name without subdomains. Use this if you do not want to use www in front of your website.

Then click on Next.

Select DNS Validation, then click on Review.

Running Minikube in AWS EC2 (Ubuntu)

If you are studying Kubernetes and having a hard time running Minikube on an EC2 Instance, you are not alone. I had a hard time doing it when it was my first time.

Below are the steps (and some comments) that I took to help me run Minikube on my EC2 Instance.

Installation of Minikube on EC2 Ubuntu

1. Run a public EC2 Server with the following setup

AMI Ubuntu Server 18.04 LTS (HVM), SSD Volume Type
Instance Type t2.micro
Storage 8 GB (gp2)
Tags – Key: Name
– Value: Minikube
Security Group Name: Minikube Security Group
– SSH, 0.0.0.0/0
Later we will be editing this.
Key Pair Create your own keypair.
You will need this to SSH to your EC2 Instance

The above setup is within the AWS Free Tier so you could try Minikube on EC2 without spending money. But you can run Minikube on a bigger instance if you like.

2. SSH into your created EC2 Instance using your keypair.

3. Install kubectl

4. Install Docker

Minikube requires Docker. Continue reading Running Minikube in AWS EC2 (Ubuntu)
