Hey @Diwakar, Once you know AWS, it's better to learn a few DevOps tools and a few programming languages to increase the scope of application and also increases the chances of getting a job.
You technology requirements changes from company to company. Know just Docker and Kubernetes with AWS is not enough in my personal opinion. Its better you learn a few more DevOps tools like - Git, Jenkins, one of the configuration management tool(Ansible, Chef, puppet), maven, No doubt Docker and Kubernetes are one of the most widely used tools but knowing just those two will not give you a good job.
Let know what job profile you've been looking and I'll help you out more with requirements. As of now go through these blogs:
