Using AWS Services through AWS CLI

Completed Some Beginner Task over AWS using AWS CLI

Task Description:

đź”… Create a key pair

đź”… Create a security group

đź”… Launch an instance using the above created key pair and security group.

đź”… Create an EBS volume of 1 GB.

đź”… The final step is to attach the above created EBS volume to the instance you created in the previous steps.

Tools Used:


Task Procedure:

Installation of AWS CLI to our system by downloading and installing the software from the AWS website

For confirmation of installation, we need to run the command

aws --version

This indicates that AWS CLI is successfully installed.

For Configuring the AWS CLI we have to provide it with the access key and secret key of our AWS account to login through the account using CLI.

aws configure

For Creating Key Pair

aws ec2 create-key-pair --key-name MyKeyPair --query 'KeyMaterial' --output text | out-file -encoding ascii -filepath MyKeyPair.pem

AWS creates the KeyPair in .pem extension for ssh using system third party software we require to convert from .pem to .ppk. [One of the software which I used was puttygen]

Once you are done with Creating the KeyPair

Change mode of execution of keypair

chmod 400 .\MyKeyPair.pem

Now Let’s go to the next step to create a security group using CLI

The command for this is

aws ec2 create-security-group --group-name Security_Group_cli --description "CLI security group"

Adding Rules to Security Group for ssh connection to Instance

aws ec2 authorize-security-group=ingress --group-id <group-id> --portocol tcp --port 22 --cidr <Public IPs/CIDR>
aws ec2 describe-security-groups --group-ids <group ID>
Showing Security group created successfully

For Launching Instance using Key pair and security group

aws ec2 run-instances --image-id  AMI ID --instance-type instance type --key-name keyname --security-group-ids security group id --tag-specification 'ResourceType=instance,Tags=[{Key=Name,Value=<Instance name>}]'

create an EBS volume of 1 GB.

For this, we give information about the availability zone, volume of other information according to our use cases.

Command is

aws ec2 create-volume --size <sizeofvolume> --availability-zone <availabilityzone>

Using this command we can fetch the complete info about any Volume

aws ec2 describe-volumes --volumes <Volume ID>

For confirmation, we can check GUI

Let’s move on to the final step

To attach the above created EBS volume to the instance created in the previous steps.

The requirement for this is the volume id of the EBS volume we have created and the Instance ID to which we want to attach to this volume.

The command for this is

aws ec2 attach-volume --volume-id volume_id_of_block --instance-id instance_id  --device /dev/sdb

Confirming that the Instance which we launched have two disks connected

To modify the Root Disk Size

aws ec2 modify-volume --region <regionName> --volume-id <volumeId> --size <newSize> --volume-type <newType> --iops <newIops>

Iops → Input-output speed per second from disk

Showing disk size before running the command
Compare the above pics using the Volume ID And see that the Size is increased after the command is run
