How to create an aws instance using an instance template in the aws cli

How do I create an instance with a chosen name from an instance template on aws.

Previously when I was on google cloud, first I created an instance template for example it was called node-template.

To create servers, I would use the following command in the gcloud cli,

gcloud instances create node-1 --source-instance-template=node-template
gcloud instances create node-2 --source-instance-template=node-template
gcloud instances create node-3 --source-instance-template=node-template
....

Is something similar possible with aws?

I basically need to create multiple instances with similar specs and be able to start them, SSH into them and stop them everyday.

The AWS CLI command aws ec2 run-instances can be used to launch Amazon EC2 instances. See: run-instances — AWS CLI Command Reference

The command allows all parameters to be specified in JSON, and this can come from disk:

aws ec2 run-instances --cli-input-json file://my-parameters.json

See: Loading AWS CLI parameters from a file - AWS Command Line Interface

Alternatively, you might want to Launch an instance from a launch template - Amazon Elastic Compute Cloud, which is a pre-defined definition of an Amazon EC2 instance that is stored in your AWS Account. You can then reference this launch template when launch an instance:

aws ec2 run-instances --launch-template LaunchTemplateName=MY-LAUNCH-TEMPLATE

Names of instances can be assigned by specifying a Name tag:

aws ec2 run-instances --tag-specifications 'ResourceType=instance,Tags=[{Key=Name,Value=MY-INSTANCE-NAME}]' --launch-template LaunchTemplateName=my-launch-template
