  What is Kubernetes? Introduction In 2017, the container orchestration space was overcome by Kubernetes (k8s). Docker Swarm and Mesos have been presenting container orchestration instruments for a long time, for example, by Kubernetes components. They two helped the Kubernetes in their surroundings. Kubernetes has declared reconciliations to its individual cloud stadiums, for example, AWS, Microsoft Azure and Oracle Cloud. Every developer and the dev-ops engineer would thus benefit by learning Kubernetes nuts and bolts. In fact, this is what we are going to do in this article. What is Kubernetes?

AWS: Creating an IAM user

Image
As the AWS services like Amazon EC2 are accessed using the provided credentials when we access these services it will check whether we have the permissions to access the resources the  console  asks for the password. We can create the access keys to access the AWS account from command line or API interfaces. But for the security reasons Amazon will not recommend that to access the AWS account using the credentials which we created while the  Sign  UP. For that Amazon recommends to use the IAM  (  Identity and Access Management) instead. To create an IAM user and then add the user to an IAM group with administrative permissions and grant the user with administrative permissions we can access AWS using the special URL and credentials for that IAM user. T o create a group for administrators a).  Sign in to the AWS Management Console and open the IAM console at https://console.aws.amazon.com and Click on  Sign in the Console. ...
