Install and configure Chef adapter (associate with Jenkins)

Install and configure the Chef adapter to associate with Jenkins.

Add Chef deployment as a tool in TeamForge project

1. In TeamForge, go to the Project Admin page of the project for which you wish to integrate this Chef deployment scenario.
2. Select Tools from the left pane.
3. Click Add Tool.
4. Select Other for SELECT TOOL TYPE option.
5. Select the Include Traceability check box.
6. Select Custom Activity Source for "Source Type".
7. Select the desired Jenkins/Build source in the Associated Source field.
8. Finish any other confirmation, then click SHOW CONFIGURATION before saving the configuration. Copy all configuration parameters to a text file for use in later steps.

Configuring Chef

9. Add the following code to your deployment cookbook’s metadata.rb file.

   depends 'teamforge-associations', '~> 0.1.0'

10. Add the following code to your recipes/default.rb file of your deployment cookbook.

    include_recipe 'teamforge-associations::alldetails'

11. Edit your deployment recipe to notify the TeamForge EventQ reporting recipe when it is run. This can be done by adding the following code to your deployment resource.

    notifies :enable, 'chef_handler[CustomHandler::AllDetails]'

12. Edit your attributes/default.rb file or any other attributes file that you are using for this recipe and add the following attributes.

    default['teamforge-associations']['alldetails']['data_bag'] = 'traceability_parameters'

    Note: This parameter denotes the data bag name on the Chef Server that has been written by Jenkins.

    default['teamforge-associations']['alldetails']['ctf_url'] = <CTF URL>

    default['teamforge-associations']['alldetails']['ctf_user'] = <CTF USER>

    Note: This user must have rights to get/post schema on EventQ.

    default[‘teamforge-associations’]['alldetails']['orc_server'] = '<ORC QUEUE SERVER>'

    default['teamforge-associations’]['alldetails']['orc_user'] = '<QUEUE USERNAME>'

    default['teamforge-associations']['alldetails']['orc_src_assoc_key'] = ‘<SOURCE ASSOCIATION KEY>’

    default['teamforge-associations']['alldetails']['orc_queue_name'] = 'eventq.custom'

    default['teamforge-associations']['passwords']['secret_path'] = '<PATH TO SECRET KEY>'

    Note: This parameter contains the generic path on each node to the encryption key that has been used to encrypt the EventQ password that resides on the Chef server as an encrypted data bag.
13. Create a data bag named "passwords" on the Chef server and add two encrypted data bag items named 'ctf_password' and 'orc_password' containing the encrypted CTF password for the user set in default['teamforge-associations']['alldetails']['ctf_user'] and the EventQ password for the user set up in default['teamforge-associations’]['alldetails']['orc_user'] respectively. The passwords must be contained in a field named “password” in their respective data bags. Please see http://docs.chef.io for information on using data bags.
14. Once all changes are in place, upload the cookbook to the server. Any nodes that this cookbook is assigned to will automatically pick up these changes when they run chef-client next. If you wish to assign it to any new nodes, follow the usual procedure to bootstrap the node and assign this cookbook to its runlist.

Configuring Jenkins

To create an association between a Jenkins build and a Chef deployment, the Chef deployment must be made aware of the "current"' build number. To achieve this, Jenkins must be configured to create a data bag on the Chef server and write its build number to the data bag item. Please follow these instructions:

15. Install Python version 2 on the host running Jenkins, if it is not already present. Please note that the expected version is python2 (i.e., 2.7.x).
16. On the Jenkins server, install the python library 'pychef', version 0.2.3 or later. Pychef is a tool needed for Jenkins to communicate with and operate on Chef. Installing Pychef can usually be achieved with the following commands:
    • sudo easy_install pip
    • sudo pip install pychef
17. Verify Pychef installation.
    1. Enter python from the command line interface.
    2. Enter import chef at the Python prompt.
    3. If “import chef” is without any errors, Pychef installation is successful. Enter CTRL+D to exit the Python shell.
    4. If there are errors about missing “libcrypto.so”, you must install the openssl developer package for your OS. Once installed, verify Pychef installation again.
18. Download the scripts to write/update from Jenkins to Chef DataBag from the EventQ community site. The contents are a directory named “pychef” with two scripts inside it namely “data_bag” and “set_jenkins_data_bag.py”.
19. Login into the shell of the Jenkins server as the user “jenkins”.
20. Enter “cd” to make sure you are in the home directory.
21. Copy the “pychef” directory and it’s contents downloaded in step 17 into the home directory.
22. Copy the “.chef” directory that is part of the starter kit into the pychef directory. Add a build step in Jenkins, after the actual build takes place, using option “execute command” and enter the following in the available text area:

    cd ${HOME}/pychef
    ./data_bag -b ${BUILD_NUMBER}
