aws --version

Once you have installed the AWS CLI, open a terminal and run the command aws configure to configure your account credentials.

Enter your AWS Access Key ID and Secret Access Key

aws configure

List s3 buckets using below command:

aws s3 ls

you can use the aws s3 cp command to copy the file from your S3 bucket to your EC2 instance and view content of file using cat command.

Use the following command to access the file from the s3 bucket.

aws s3 cp s3://bucket-name/file-name .

The file will be downloaded from the s3 bucket and stored in the current directory of the ec2 instance.

Task-02

Create a snapshot of the EC2 instance and use it to launch a new EC2 instance.

Select the EC2 instance that you want to create a snapshot of.

Snapshot created.

Use snapshot to launch a new EC2 instance

In right side, click on Actions and select 'Create image from snapshot'

In the "Create Image from snapshot" window, enter a name and description for the image.

Review the instance details and click "Launch instance" to launch the new instance.

Connect to instance using SSH:

here login as the user "ubuntu" rather than the user "root"

Download a file from the S3 bucket using the AWS CLI.

aws s3 cp command to download the file from your S3 bucket to your EC2 instance.

aws s3 cp s3://BUCKET_NAME/PATH/TO/FILE /PATH/TO/LOCAL/FILE
ls
