Images

Images is a tool to manage machine images from multiple providers over a single CLI interface. Its fast(concurrent actions), simple to use and and very flexible. Think of it as a companion to the popular image creation tool Packer. You can fetch images from multiple providers, delete them, change tags or names of multiple images, any many other things.

Features

• Multiple provider backend support: AWS, DigitalOcean, GCE, etc...
• Multi region support
• List images from multiple regions/providers
• Modify image attributes, such as tags, names, states
• Delete images
• Copy images from one region to another region
• Commands are executed concurrently (delete, list, etc..).
• Flexible configuration system. Read from file, environment variables or command line flags.

Installation

Images is still under development. Any feedback/contribution is welcome! Download the latest release suitable for your system:

=> Images releases

Or if you have Go installed, install latest development version:

go get -u github.com/fatih/images

Intro

To list all commands just run images:

$ images
usage: images [--version] [--help] <command> [<args>]

Available commands are:
    copy        Copy images to regions
    delete      Delete available images
    list        List available images
    modify      Modify image properties
    version     Prints the Images version

...

Because images is built around to support multiple providers, each provider has a specific set of features. To display the specific provider help message pass the -providers name -help flags at any time, where name is the provider name, such as "aws".

Current supported providers are:

• aws
• do
• gce

Coming soon:

• virtualbox
• docker

Configuration

images is a very flexible CLI tool. It can parse the necessary configuration from either a file, from environment variables or command line flags. Examples:

$ images list --providers aws --regions "us-east-1,eu-west-2" --access-key "..." -secret-key "..."

or via environment variable:

$ IMAGES_PROVIDERS=aws IMAGES_AWS_REGIONS="us-east-1" IMAGES_AWS_ACCESS_KEY=".." images list

or via .imagesrc file, which can be either in TOML or JSON. Below is an example for TOML:

providers = ["aws"]
no_color  = true

[aws]
regions    = ["us-east-1","eu-west-2"]
access_key = "..."
secret_key = "..."

and execute simply:

$ images list

Usage

images has multi provider support. The following examples are for the provider "aws". The commands are supposed to be executed with IMAGES_PROVIDER=aws or with --providers aws or added to .imagesrc file via providers = "aws"

List

List images for a given region. Examples:

$ images list -regions "us-east-1"

List from all regions (fetches concurrently):

$ images list -regions "all"

List from multiple providers (fetches concurrently):

$ images list -providers "aws,do"

List from all supported providers

$ images list -providers "all"

Change output mode to json

$ images list -output json

Delete

Delete images from the given provider. Examples:

$ images delete -ids "ami-1ec4d766,ami-c3h207b4,ami-26f1d9r37"

Note that you don't need to specify a region if you define multiple ids. images is automatically matching the correct region and deletes it. Plus they all are deleted concurrently.

Modify

images allows to change the tags of AWS images for the provider "aws".

To create or override a image tag:

$images modify --create-tags "Name=ImagesExample" --ids ami-f465e69d

To delete the tags of an image

$images modify --delete-tags "Name=ImagesExample" --ids ami-f465e69d

The commands also have support for batch action:

$images modify --create-tags "Name=Example" --ids ami-f465e69d,ami-c5c237ac,ami-64pgca7e
$images modify --delete-tags "Name=Example" --ids ami-f465e69d,ami-c5c237ac,ami-64pgca7e

Just like for the delete command, all you need to give is the ami ids. images will automatically match the region for the given id. You don't need to define any region information.

Copy

Copy supports copying an AMI to the same or different regions. Below is a simple example:

$ images copy -image "ami-530ay345" -to "us-east-1"

Copy supports concurrent copying to multiple regions.:

$ images copy -image "ami-530ay345" -to "us-east-1,ap-southeast-1,eu-central-1"

Description can be given too (optional):

$ images copy -image "ami-530ay345" -to "us-east-1"  -desc "My new AMI"

Build & Development

To build images just run:

$ make build

This will put the images binary in the bin folder. Development builds doesn't have a version, so if called with "--version" it'll output dev:

$ .bin/images --version
dev

For creating release binaries run (goxc required):

IMAGES_VERSION="0.1.0" make release
