How to run user data in windows instance using boto3?

0 votes

Hi,

I would like to launch windows ec2 instance using boto3. But I need to run some user data too. Is possible to place user-data during the launch ec2 instance? I have tried with the below code. But not creating anything.

#!/usr/bin/env python3

import boto3
import time

dryRun = False; # useful variable to put the script into dry run mode where the function allows it

ec2Client = boto3.client('ec2')
ec2Resource = boto3.resource('ec2',region_name='us-west-2')
ec2 = boto3.resource('ec2')

user_data = '''<script>

net user /add Latchu ABC@123
net localgroup administrators Latchu /add

</script>'''

# Create the instance
instanceDict = ec2.create_instances(
    DryRun = dryRun,
    ImageId = "ami-xxxxx",
    KeyName = "ZabbixServerPrivateKey",
    InstanceType = "t2.micro",
    SecurityGroupIds = ["sg-xxxxxxx"],
    MinCount = 1,
    MaxCount = 1,
    UserData=user_data
)

Hi@Lakshminarayanan,

I think you used the wrong keyword in the create_instance method. You can pass  user_data as a key. But you have used UserData. So change the key and try once. If you need more information then check all the key that is supported by the create_instances method.

I just followed this link.

https://stackoverflow.com/questions/44190556/ec2-user-data-not-working-via-python-boto-command

but they used for linux based Ec2 instance.

Any idea for windows based instance?
Hi,

First, replace the line UserData=user_data with user_data=user_data. It supports only the user_data key.
hi

when i use user_data instead of UserData

raise ParamValidationError(report=report.generate_report())
botocore.exceptions.ParamValidationError: Parameter validation failed:
Unknown parameter in input: "user_data", must be one of: BlockDeviceMappings, ImageId, InstanceType, Ipv6AddressCount, Ipv6Addresses, KernelId, KeyName, MaxCount, MinCount, Monitoring, Placement, RamdiskId, SecurityGroupIds, SecurityGroups, SubnetId, UserData, AdditionalInfo, ClientToken, DisableApiTermination, DryRun, EbsOptimized, IamInstanceProfile, InstanceInitiatedShutdownBehavior, NetworkInterfaces, PrivateIpAddress, ElasticGpuSpecification, ElasticInferenceAccelerators, TagSpecifications, LaunchTemplate, InstanceMarketOptions, CreditSpecification, CpuOptions, CapacityReservationSpecification, HibernationOptions, LicenseSpecifications, MetadataOptions

Hi,

You can go through the below official document. In the Boto3 you can use the UserData key. You will also get the idea of why you are getting the above error.

Hi ,

I got solution,,,its simple mistake. That boto3 script is good.

why user-data not applied? - Because password length is not allow me to run the simple user creation command. When i used simple password than complex (like 8 digit password than 22 digit password), then user-data is applied.

Many thanks for ur kind
