AWS Task-1 using AWS CLI.

What is AWS CLI?

The AWS Command Line Interface (CLI) is a unified tool to manage your AWS services. With just one tool to download and configure, you can control multiple AWS services from the command line and automate them through scripts.

1.First we need to install AWS CLI software.

https://awscli.amazonaws.com/AWSCLIV2.msi

2.After successfully installing,create a IAM User in AWS.

Attach existing policies(policy name):power user access,so that we can access any services except billing account and IAM account.

3.Create user.

4.Then open CLI and then configure AWS by providing access key and secret key.

5.Then create key pair by using the command:

aws ec2 create-key-pair --key-name key-name

6.key pair is successfully created.

7.In this step we will create a security group using the command:

aws ec2 create-security-group --group-name security --description securitygroup

Security group has been created.

8.Then we have to add inbound rules using the command:

aws ec2 authorize-security-group-ingress --group-name security --protocol tcp --port 22 --cidr 0.0.0.0/0

9.Now we launch an instance using the key pair and security group that has been created else it will use the default security group.

In the above command image-id is AMI id.An AMI is a template that contains the software configuration (operating system, application server, and applications) required to launch your instance.

Instance type is t2.micro.Amazon EC2 provides a wide selection of instance types optimized to fit different use cases. Instances are virtual servers that can run applications. They have varying combinations of CPU, memory, storage, and networking capacity, and give you the flexibility to choose the appropriate mix of resources for your applications.And count is how many instances you want to launch.

10.Now I have created a volume of 1 GB using AWS CLI:

11.In above image you can see volume has been created and it is available,now we have to attach this volume to the instance.

Now you can see volume is attached to an instance and it is in use.

Note:Create and attach the volume in the same region as instance or else it gives error.

12.Now to stop instances we use the following command:

aws ec2 stop-instances --instance-ids i-0b249600d4cc2f740

13.Then terminate the instances:

aws ec2 terminate-instances --instances-ids i-0b249600d4cc2f740
