# **cloud-utils** #

A useful set of utilities for interacting with a cloud.

## Install ##

cloud-utils is available in Ubuntu and Debian via the `cloud-utils` metapackage:

sudo apt update
    sudo apt install cloud-utils

Red Hat based distributions offer the `cloud-utils` package with a subset of binaries and `cloud-utils-growpart` for growpart.

The package is also available in Alpine and Arch as `cloud-utils`.

## Usage ##

*  **`cloud-localds` - create a disk for cloud-init to utilize the nocloud datasource**
 *  `ec2metadata` - query and display AWS EC2 metadata
 *  `growpart` - rewrite partition table so that partition takes up all the space it can
 *  `mount-image-callback` - mount a file to a temporary mount point and then invoke the provided cmd with args
 *  `resize-part-image` - resize a partition image and contained filesystem to a new size
 *  `ubuntu-cloudimage-query` - get the latest Ubuntu AWS AMI meeting certain criteria
 *  `vcs-run` - obtain a repository and execute a command with arguments
 *  `write-mime-multipart` - utilty for creating mime-multipart files, likely for use via user data and cloud-init
