The API has changed but it's right there in the documentation
API 已更改，但它就在文档中
# Boto 3
ec2.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

Refer to API docs has all available options to create instance
请参阅 API 文档，其中包含创建实例的所有可用选项

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:
您在文档中真正要查找的链接是create_instances()ServiceResource 对象的方法。如果您像这样创建 EC2 资源，这就是您要调用的对象类型：
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.
这包含更详细的示例和更长的可用参数列表。
You can also get parameter values for AWS instances that are already running using the AWS command line interface:
您还可以使用 AWS 命令行界面获取已运行的 AWS 实例的参数值：
$ 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.)
这会打印出一个 JSON 文件，可以从中提取相关参数并将其传递给create_instances()方法。（或者，您可以使用 boto 客户端并调用describe_instances()方法。）
(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.)
（注意：如果您想知道 Client 和 Resource 之间的区别是什么，它们为同一端提供不同的用途 - 客户端是较低级别的接口，而 Resource 是较高级别的接口。）

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:
您可以运行我从boto3 docs使用的代码。您可以根据您的要求添加或删除参数，但这是您通常需要的：
import boto3
client = 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',
],
)

If your running from your windows computer you need configure AWS Cli with proper EC2 permisssion to launch instance.
如果您从 Windows 计算机运行，则需要使用适当的 EC2 权限配置 AWS Cli 以启动实例。
#import boto3
ec2 = boto3.resource('ec2')
instance = ec2.create_instances(
ImageId='ami-5eb63a32',
MinCount=1,
MaxCount=1,
InstanceType='t2.micro',
)
print(instance[0].id)
