MiniMart is a RubyGem that makes it simple to build a repository of Chef cookbooks using only static files.
Minimart is made up of two main components:
-
A mirroring tool that will download any cookbooks described in an inventory file.
-
A web tool that will generate a Berkshelf compatible index of the cookbooks in your inventory, and a user friendly web interface for browsing cookbooks.
Add this line to your application's Gemfile:
gem 'minimart'And then execute:
$ bundle
Or install it yourself as:
$ gem install minimart
After installing the minimart gem, you can start a new MiniMart by running the following command:
$ minimart init
The init command will generate a sample inventory.yml file for you to use as a reference when building your own inventory. A real inventory may look like the following:
sources:
- "https://supermarket.chef.io"
cookbooks:
apache2:
versions:
- '= 3.0.0'
- '= 2.0.0'
nginx:
version: "~> 2.7.0"
git:
location: "https://github.com/miketheman/nginx.git"
tags:
- 'v2.6.0'
- 'v2.5.0'
This file allows you to specify multiple sources to fetch cookbooks from (in order of precedence). You can also specify multiple versions of the same cookbook, either from one of the sources, using Git, or a local path. All of the version style commands allow for plural, and singular YAML keys (version, versions, branch, branches, etc...).
Once you are done modifying the inventory.yml file, you can run the mirror command to download any cookbooks to your local inventory.
$ minimart mirror
- NOTE: The ExecJS Gem requires a Javascript runtime to be installed before running this command. See https://github.com/rails/execjs for runtimes that can be used.
By default this will not load the dependencies of the cookbooks in your
inventory.yml file. If you require it to also grab all the dependencies
then you should use the --load-deps option. Warning, this may be very
slow if you have a large inventory file.
$ minimart mirror --load-deps
The above inventory file would download multiple versions of the apache2, and nginx cookbooks. The inventory directory would have the following structure:
inventory
├── apache2-2.0.0
│ ├── README.md
│ ├── metadata.rb
│ ├── ... (all of the other cookbook files)
├── ... (directories and files for other cookbooks)
Once you are satisfied with the cookbooks in your inventory, you can use the web command to generate the MiniMart index file, archived cookbook directories, and static HTML for browsing any mirrored cookbooks. This directory structure will be built in your local directory (wherever you are running minimart), and can be synced to your web server, s3, etc...
The web command requires the user to specify a host to build a proper index file. The host should be the domain name, or IP you plan to use to host Minimart. To generate a MiniMart that would be hosted on example.com you would run:
$ minimart web --host=http://example.com
web will run through any of the cookbooks in the inventory, and generate the following:
web
├── assets
│ ├── ... (CSS, JS, etc...)
├── cookbook_files
│ ├── apache2
│ │ └── 2_0_0
│ │ └── apache2-2.0.0.tar.gz
│ ├── nginx
│ │ └── ... (additional .tar.gz cookbooks)
├── cookbooks
│ ├── apache2
│ │ └── 2.0.0.html
│
├── index.html
├── universe
It is important to note the creation of the universe file. This is the JSON index file that is necessary for MiniMart to work with Berkshelf. It contains a listing of all cookbook versions, and where they can be found (hence the need for the host).
Deploying MiniMart should be as easy as syncing the contents of your web directory to a web server that will serve static files.
The caveat is that you must configure your server to serve the universe file with a content-type of application/json.
You must set the 'Content-Type' Metadata of universe to application/json with the tool you are using to sync files to S3.
In your nginx.conf:
location /universe {
default_type application/json;
}
In your apache2.conf:
<Location "/universe">
ForceType application/json
</Location>
If you are using berkshelf-api, you can add chef, and github configuration options to your inventory.yml file to properly download cookbooks from those sources.
sources:
- "api.berkshelf.com"
configuration:
verify_ssl: true # This defaults to true!
chef:
client_name: 'berkshelf'
client_key: '/path/to.pem'
github:
organization: "org-name"
api_endpoint: "https://api.github.com/"
web_endpoint: "https://api.github.com/"
This is an example of a script that can be used by Jenkins to sync the
cookbooks to the S3 bucket. This script can be placed in the same
directory as the inventory.yml file created by minimart init. This
can be pulled down from a repository and then ran by Jenkins.
#!/bin/bash
# Exit 1 if any command fails
set -e
# Name of the repository bucket
BUCKET_NAME=your.s3.bucket.name
