How to create an ec2 instance using boto3

The API has changed but it's right there in the documentation

# Boto 3ec2.create_instances(ImageId='<ami-image-id>', MinCount=1, MaxCount=5)

Link to the documentation:http://boto3.readthedocs.org/en/latest/guide/migrationec2.html#launching-new-instances

You can run the code I used from the boto3 docs. You can add or remove parameters as per your requirements, but this is what you would normally require:

import boto3client = boto3.client('ec2', region_name='us-west-2')response = client.run_instances(    BlockDeviceMappings=[        {            'DeviceName': '/dev/xvda',            'Ebs': {                'DeleteOnTermination': True,                'VolumeSize': 8,                'VolumeType': 'gp2'            },        },    ],    ImageId='ami-6cd6f714',    InstanceType='t3.micro',    MaxCount=1,    MinCount=1,    Monitoring={        'Enabled': False    },    SecurityGroupIds=[        'sg-1f39854x',    ],)

The link you're really looking for in the documentation is the create_instances() method of the ServiceResource object. This is the type of object you are calling if you create an EC2 resource like this:

s = boto3.Session(region_name="us-west-1")ec2 = s.resource('ec2')...instance = ec2.create_instances(**y_kwargs)

This contains a more detailed example and a longer list of available parameters.

You can also get parameter values for AWS instances that are already running using the AWS command line interface:

$ aws ec2 describe-instances

This prints out a JSON file from which relevant parameters can be extracted and passed to the create_instances() method. (Or, you can use a boto client and call the describe_instances() method.)

(Note: If you're wondering what the difference is between the Client and the Resource, they serve different purposes for the same end - the client is a lower-level interface while the Resource is a higher-level interface.)
