unzip awscliv2.zip
sudo ./aws/install
aws configure && aws configure list
- Check the list of s3 and use the
aws s3 cp
command to copy the file from the S3 bucket to your EC2 instance:
aws s3 ls
aws s3 cp s3://<bucketname>/<content> /home/ubuntu
Task-02
Create a snapshot of the EC2 instance and use it to launch a new EC2 instance.
- Go to the EC2 dashboard and select the running instance and Click on "Actions" -> "Image and templates" -> "Create Image" to create a snapshot (AMI) of the instance.

Connect to the new EC2 instance using SSH.
Install and configure the AWS CLI and configure as done previously with same Access key & Secret access key.
sudo apt-get update && sudo apt-get install awscli -y
aws configure
- Use the
aws s3 cp
