cloudinit-userdata-builder

About

This script bundles a number of files into cloudinit supportable userdata, which can be passed to your instances (which may be running in your local DC, on AWS or on other cloud providers)

Installation

go get github.com/boyand/cloudinit-userdata-builder

Usage

This binary supports two flags by default: config file path and encode flag for output formatting. In order to use it, your need to supply a config file for your userdata using the following format:

cat userdata.conf

{
    "cloud_init_parts": [
        [
            "/path/to/part-handler.py",
            "text/part-handler"
        ],
        [
            "/path/to/cloudinit.txt",
            "text/cloud-config"
        ],
        [
            "/path/to/your/script.sh",
            "text/cloud-boothook"
        ]
    ]
}

If you want to use the binary to build drop-in bundle for AWS, you can run it with:

cloudinit-userdata-builder --config="/path/to/userdata.conf" --encode
