Day 22 : Configuring Secure SSH Access to an EC2 Instance

I'm Zin Lin Htet. Who love to learn and share about Linux, Cloud, Docker and K8s. Currently working as a DevOps Engineer at one of the famous Fintech Company in Myanmar.

Part of series100 Days of Cloud (AWS)

Welcome back to Day 22. In this lab, you will learn how to set up secure SSH access to an EC2 instance without using a password. You need to create an EC2 instance and name it nautilus-ec2. Then, generate an SSH key on the aws-client host.

After setting up an EC2 instance, generate an SSH key using the ssh-keygen command. You need to upload your id_rsa.pub key file to the EC2 instance's root SSH authorized_keys.

Congratulations you did it. It looks good. This lab was successfully completed without any errors. See you in day 23. If you have any issues please let me know I will be happy to assist you. Stay tuned and learn together. If you find my article useful, please kindly like and share it.
