Packer user_data_file on on AWS without <powershell>
To provide user data to an EC2 instance created by Packer on AWS without using the <powershell>
block, you can make use of the user_data_file
parameter in the Packer template. The user_data_file
parameter allows you to specify a file that contains the user data to be passed to the instance.
Here's an example of how to use the user_data_file
parameter in your Packer template:
json{
"builders": [
{
"type": "amazon-ebs",
"region": "us-west-2",
"source_ami": "ami-xxxxxxxx",
"instance_type": "t2.micro",
"user_data_file": "user_data.txt",
"ssh_username": "ubuntu",
"ami_name": "my-ami",
"tags": {
"Name": "my-ami"
}
}
]
}
In this example, the user_data_file
parameter is set to "user_data.txt"
, which refers to a text file that contains the desired user data for the instance. You need to create the user_data.txt
file and specify the necessary user data in that file.
The contents of the user_data.txt
file can include any commands or scripts you want to run during the instance startup. It can be shell scripts, configuration files, or any other commands that you want to execute on the instance.
Once you have the user_data.txt
file ready with the desired user data, make sure it is located in the same directory as your Packer template or provide the correct path to the file in the user_data_file
parameter.
When you run Packer with this template, it will read the contents of the user_data.txt
file and pass it as user data to the created EC2 instance.
Remember to ensure the user data file (user_data.txt
) and its contents are properly validated, secure, and conform to AWS EC2 user data requirements.
