Hello folks, I am trying to run a script through userdata as per the example shown but look like it’s not successfully running.

user_data = """
#!/bin/bash

## Checking if Splunk user exist ##
if getent passwd splunk > /dev/null 2>&1;
then
    echo "splunk user exist"
else
    useradd -m splunk
    echo 'splunk    ALL=(ALL:ALL)   ALL' >> /etc/sudoers
    echo 'splunk    ALL=(ALL:ALL)   NOPASSWD' >> /etc/sudoers
fi
"""
Instances = aws.ec2.Instance(
                ins_name,
                user_data = user_data,
                ami = ami_centos.value,
                iam_instance_profile = iam_profile,
                instance_type = self.instance_type,
                subnet_id = sbnet,
                tags={"Name": ins_name},
            )
            instance_info = {
                "id": Instances.id,
                "primary_network_interface_id": Instances.primary_network_interface_id,
                "instance_name": ins_name,
            }
)

you should check the cloud init logs on the instance

I checked those and no updates regarding userdata, i doubt it’s executing the userdata part.

can you see the userdata on the instance in the console?

No actually, it’s not running anyway, that’s the reason i am concerned if it’s right method to do so

can you print the output of

aws ec2 describe-instance-attribute --attribute userData --instance-id <instance created with pulumi>

Sure, let me run the stack again .

If you base64 decode that, it looks like there's some binary data at the end, so I think your input value for userdata might be invalid.

Ohh that make sense @gentle-diamond-70147 I agree on the first line should be #!/bin/bash

Can you try a simpler script with

echo "Hiiii!"

or similar to see if that works?

Still didn’t work, not sure what’s wrong here.

What does your cloud init log say?

You need to encode the script with base64. In Python, use

base64.standard_b64encode(...)

.
