CREATE AN EC2 INSTANCE USING AWSCLI

TO CREATE EC2 INSTANCE , WE NEED THE FOLLOWING

For creating ec2 instance we have following needs AMI id: They differ from region to region for the same OS (ubuntu 22.04) Network VPC (Region): AWS CLI by default uses default vpc to launch ec2 instance. Subnet id: For choosing specific AZ. Security Group: Solved as part of activity 8 Key-Pair: Use the current machines id_rsa.pub (i.e. import) Create a new key pair and store it some where in your system. Size: EC2: this can be a parameter EBS: this can be a parameter

aws ec2 describe-images --filters "Name=owner-id,Values=099720109477" "Name=name,Values=ubuntu/images/hvm-ssd/ubuntu-focal-20.04-amd64-server-20221201" --query "Images[].ImageId"

$ aws ec2 describe-images --filters "Name=owner-id,Values=099720109477" "Name=name,Values=ubuntu/images/hvm-ssd/ubuntu-focal-20.04-amd64-server-20221201" --query "Images[].ImageId" [ "ami-03d3eec31be6ef6f9" ]

to remove the quotes in o/p

to get ubuntu20.04 ami-id in any region use '--region '

Exercise: Try to find AMI id of Redhat Linux 9 which works for all regions

Hint: use Name and owner id for fetching images uniquely

$ aws ec2 describe-images --filters "Name=owner-id,Values=309956199498" "Name=name,Values=RHEL-9.1.0_HVM-20221101-x86_64-2-Hourly2-GP2" --query "Images[].ImageId" --output text ami-0f9d9a251c1a44858

to get the RED HAT LINUX 9 ami-id in any region use '--region '

$ aws ec2 describe-images --filters "Name=owner-id,Values=309956199498" "Name=name,Values=RHEL-9.1.0_HVM-20221101-x86_64-2-Hourly2-GP2" --query "Images[].ImageId" -- region us-west-1 --output text ami-01545383151c0674e

To get the default vpc

$ aws ec2 describe-vpcs --query "Vpcs[?IsDefault].VpcId" --output text vpc-06d9bc98a2b3a2108

To get the default vpc in any region use `--region <region-name>`

$ aws ec2 describe-vpcs --query "Vpcs[?IsDefault].VpcId" --region us-west-2 --output text vpc-09c15b52ef67ed9d8

To get the subnet in default vpc with availability-zone `ap-south-1b`

$ aws ec2 describe-subnets --filters "Name=availability-zone,Values=ap-south-1b" "Name=vpc-id,Values=vpc-06d9bc98a2b3a2108" --query "Subnets[].SubnetId" --output text subnet-092eb948953e49a55

To get the Security Group in default vpc with name

$ aws ec2 describe-security-groups --filters "Name=vpc-id,Values=vpc-06d9bc98a2b3a2108" --group-names "launch-wizard-1" --query "SecurityGroups[].GroupId" --output text sg-07badd16ad39e26fb

to get the count of keypairs with name

$ aws ec2 describe-key-pairs --filters "Name=key-name,Values=my-id-rsa" --query "KeyPairs[] | length(@)" --region $region 1

to create the imported key-pair with name

$ aws ec2 import-key-pair --key-name "my-id-rsa" --public-key-material fileb://~/.ssh/id_rsa.pub

Lets create an ec2 instance in the specified region , in specified vpc/subnet with security group and key pair with instance size, disk size as parameter
