Instance-Volume Attachment using Terraform

A terraform code for all the below mentioned steps is being provided-

• Create a key pair
• Create a security group
• Launch an instance using the above created key pair and security group.
• Create an EBS volume of 10 GB.
• The final step is to attach the above created EBS volume to the?instance you created in the previous steps.

Step 1

A key-pair "task-2" is successfully created.

Step 2

provider?"aws"?{
????region?=?"ap-south-1"
????profile?=?"default"
}


#?step ->?Create?a?Security?Group


resource?"aws_security_group"?"task2-sg"?{
??name?=?"task2-sg"
??ingress?{
????from_port???=?80
????to_port?????=?80
????protocol????=?"tcp"
????cidr_blocks?=?["0.0.0.0/0"]
??}


??egress?{
????from_port???=?0
????to_port?????=?0
????protocol????=?"-1"
????cidr_blocks?=?["0.0.0.0/0"]
??}
}
        

Step 3

#?step?->?Launch?an ec2?instance


resource?"aws_instance"?"task2"?{
????ami?=?"ami-010aff33ed5991201"
????key_name?=?"task-2"?
????instance_type?=?"t2.micro"
????vpc_security_group_ids?=?[aws_security_group.task2-sg.id]


????tags?=?{
????????Name?=?"ec2_taks2"
??????????}        

}        

Step 4

#?step?->?Create?an ebs?volume


resource?"aws_ebs_volume"?"volume"?{
????availability_zone?=?aws_instance.task2.availability_zone
????size?=?10
????tags?=?{
????????Name?=?"ec2_ebs_vol_task2"
?????????}        

}        

Step 5

#?step?->?Attaching?volume?to?instance


resource?"aws_volume_attachment"?"ebs_att_task2"?{
??device_name?=?"/dev/sdh"
??volume_id???=?aws_ebs_volume.volume.id
??instance_id?=?aws_instance.task2.id        

}        

We can also fetch the desired outputs if required

#?step?->?Outputs


output?"az"?{
????value?=?aws_instance.task2.availability_zone????
}


output?"public_ip"?{
????value?=?aws_instance.task2.public_ip????        

}        

Terraform init , Plan and finally Apply
