How Launch/Create AWS Instances using AWS CLI
What is AWS Cloud?
Amazon web service is a platform that offers flexible, reliable, scalable, easy-to-use and cost-effective cloud computing solutions.
AWS is a comprehensive, easy to use computing platform offered Amazon. The platform is developed with a combination of infrastructure as a service (IaaS), platform as a service (PaaS) and packaged software as a service (SaaS) offerings.
What is AWS CLI?
It is basically a way of operating the AWS Services. With the help of CLI you can configure & control Multiple AWS services at the same time.
Pre-Requisite: One should have AWS CLI software installed in their system.
Install AWS CLI software and add it’s path to environment variable.
Now, we are ready to go!!
STEP:1
To check AWS CLI software is working or not.
aws
STEP:2 (Login)
aws configure
But it’s asking for some Access Key & Secret Key. What it is…😶. Don’t worry it’s just like a username/password asking before login. So create it first, for this create one IAM user. When you create it successfully you will get an access key(username) & secret key (password). Choose any region name as you wish.
STEP:3 (create a New Key Pair)
aws ec2 create-key-pair — key-name <key_name>
STEP:4 (Create security group)
aws ec2 create-security-group — group-name <value> — description “<value>”
STEP:5 (launch a new instance using above key-pair & security group)
aws ec2 run-instances — image-id <value> — instance-type <value> — count <value> — subnet-id <value> — key-name <value> — security-group-ids <value>
Now our instances is successfully launched😀.
STEP:6 (create EBS volume)
aws ec2 create-volume — volume-type gp2 — size 1 — availability-zone ap-south-1a
STEP:7(attach EBS volume to the instance)
aws ec2 attach-volume — instance-id <value>— volume-id <value>— device /dev/xvdf
Now in next steps we are going to detach the EBS volume & then finally terminate the instance.
Note: must detach EBS volume first before terminating the Instance.
STEP:1 (detach the EBS volume)
aws ec2 detach-volume — volume-id <value>
STEP:2 (terminate the Instance)
aws ec2 terminate-instances — instance-ids <value>
