如何在厨师中运行带有依赖项的食谱？

Question

I have configured workstation up this step in get started (OS redhat 6.5). I have launched a node. I modified a cookbook like that:

myCookbook/metadata.rb

name             'myCookbook'
maintainer       'YOUR_COMPANY_NAME'
maintainer_email 'YOUR_EMAIL'
license          'All rights reserved'
description      'Installs/Configures myCookbook'
long_description IO.read(File.join(File.dirname(__FILE__), 'README.md'))
version          '0.1.0'

depends 'maven'

Eg only depends 'maven' string was added after knife cookbook create myCookbook was executed.

myCookbook/recipes/default.rb

maven 'spring-context' do
  group_id 'org.springframework'
  version  '4.0.4.RELEASE'
  dest     '/root/chef-repo/'
  repositories ['http://repo.maven.apache.org/maven2/']
end

Then I run:

knife cookbook upload myCookbook

Now I am trying:

knife bootstrap 192.168.1.37 --ssh-user root --ssh-password '123456' --sudo --use-sudo-password --node-name node-with-maven-run --run-list 'recipe[myCookbook]'

And get:

ERROR: Cookbook myCookbook depends on cookbooks which are not currently
ERROR: being uploaded and cannot be found on the server.
ERROR: The missing cookbook(s) are: 'maven' version '>= 0.0.0'

How install all cookbook to chef server from that mtCookbook depends?

Answer 1

See here

Or just type knife cookbook upload --help and it will show you the following line (along others):

--include-dependencies Also upload cookbook dependencies

So knife cookbook upload myCookbook --include-dependencies is your answer

You'll need to have the maven cookbook on your workstation too, by knife cookbook site install maven or any other way to have a directory called maven in your local cookbook_path containing a cookbook where the metatada.rb file as a key name with value maven

@rastasheep has described how the berkshelf tool is now bundled with the chefdk package.

It's really easy to use and worth learning. It's designed to work like the gem bundler tool.

Example

└── myCookbook
    ├── Berksfile       <-- Berkshelf configuration file
    ├── Berksfile.lock  <-- Lock file generated by Berkshelf
    ├── metadata.rb
    ├── README.md
    └── recipes
        └── default.rb

Berksfile

source "https://supermarket.getchef.com"

metadata

The "source" directive tells berkshelf where to download dependencies from. The "metadata" directive tells berkshelf to take dependencies from the cookbook metadata.

Using Berkshelf

The "install" command will download the cookbook dependencies (Cached under ~/.berkshelf)

$ cd myCookbook
$ berks install
Resolving cookbook dependencies...
Fetching 'myCookbook' from source at .
Fetching cookbook index from https://supermarket.getchef.com...
Installing maven (1.2.0)
Installing 7-zip (1.0.2)
Installing ark (0.9.0)
Installing chef_handler (1.1.6)
Installing java (1.29.0)
Installing windows (1.34.8)
Using myCookbook (0.1.0) from source at .

Berkshelf can also upload all the cookbooks into your chef server

$ berks upload

Answer 3

There is a few other options for managing cookbook cookbook and dependencies, such Berkshelf or Librarian-chef, where Berkshelf is more popular, and it's even included in Chef Development Kit, so if you use it you do not need to install it separately.

After defining sources you just need to define which cookbooks you want their versions and cookbook manager will resolve dependencies for all defined cookbooks and it will install them for you, and if you want you can vendor them too. Beside that they have an option to upload specific cookbook, without worrying about upload dependencies.

For more info how to use those tools consult official websites:

• http://berkshelf.com
• https://github.com/applicationsonline/librarian-chef

In general for managing small projects you can use knife's upload flag for uploading dependencies.

-d, --include-dependencies
    Use to ensure that when a cookbook has a dependency on one (or more) cookbooks, those cookbooks will also be uploaded.
