Before Starting

This control repo and the steps below are intended to be used during a new installation of PE.

The instructions are geared towards a new installation of PE2015.3.z. However, the control-repo should work just fine on PE2015.2.z

If you intend to use this control-repo on an existing installation then be warned that if you've already written or downloaded modules when you start using r10k it will remove all of the existing modules and replace them with what you define in your Puppetfile. Please copy or move your existing modules to another directory to ensure you do not lose any work you've already started.

What You Get From This control-repo

As a result of following the instructions below you will receive at least the beginning of a best-practices installation of PE including...

• A git server
• The ability to push code to your git server and have it automatically deployed to your PE Master
• A config_version script to output the commit of code that your agent just applied
• Optimal tuning of PE settings for this configuration
• Working and example roles/profiles code

How To Set It All Up

Setup a Trusted Fact On Your PE Master

This control repository is setup to manage certain portions of your PE installation for you if you create a trusted fact called pp_role. In order to do so, lay down a file that looks exactly like the below in /etc/puppetlabs/puppet/csr_attributes.yaml

---
extension_requests:
  #pp_role
  1.3.6.1.4.1.34380.1.1.13: 'all_in_one_pe'

If You Have Not Installed PE

Good then you can proceed forward and the trusted fact will be used when you get to the install step.

If You Have Already Installed PE

Trusted facts are created at the time a CSR is generated. So, we need to regenerate the certificate on the master for the above trusted fact to be created.

Follow this document to regenerate the certificate on your master.

##Copy This Repo Into Your Own Git Server

###Gitlab

1. Install Gitlab

• https://about.gitlab.com/downloads/

2. After Gitlab is installed you may sign if with the root user and password 5iveL!fe

3. Make a user for yourself

4. Make an ssh key to link with your user. You’ll want to do this on the machine you intend to edit code from ( most likely not your puppet master but your local workstation / laptop )

• http://doc.gitlab.com/ce/ssh/README.html
• https://help.github.com/articles/generating-ssh-keys/

5. Create a group called puppet ( this is case sensitive )

• http://doc.gitlab.com/ce/workflow/groups.html

6. Create a user called r10k_api_user and add them to the puppet group

• From the landing page, select groups
• Choose the puppet group
• In the left hand pane, select memembers
• Add the r10k_api_user with master permissions

7. Add your user to the puppet group as well

8. Create a project called control-repo and set the Namespace to be the puppet group

9. Logout of root and login as the r10k_api_user

• Go to profile settings -> account ( https://<your_gitlab_server>/profile/account )
• Copy the api token

10. Clone this control repository to your laptop/workstation

• git clone <repository url>
• cd control-repo

11. git mv hieradata/nodes/example-puppet-master.yaml hieradata/nodes/<fqdn_of_your_puppet_master>.yaml

• Open hieradata/nodes/<fqdn_of_your_puppet_master>.yaml
  • edit gms_api_token to be your api token
  • edit git_management_system to be 'gitlab'
  • edit the gms_server_url

12. git add hieradata/nodes/<fqdn_of_your_puppet_master>.yaml

13. git commit -m "renaming example-puppet-master.yaml"

14. Rename my repository as the upstream remote

• git remote rename origin upstream

15. Add your internal repository as the origin remote

• git remote add origin <url of your gitlab repository>

16. Push the production branch of the repository from your machine up to your git server

• git push origin production

17. git branch --set-upstream-to origin/production

###Stash

Coming soon!

###Github

Coming soon!

##Configure PE to Use the Control-Repo

###Install PE

1. Download the latest version of the PE installer for your platform and copy it to your master

• https://puppetlabs.com/download-puppet-enterprise

2. Expand the tarball and cd into the directory
3. Run puppet-enterprise-installer to install

If you run into any issues or have more questions about the installer you can see our docs here:

http://docs.puppetlabs.com/pe/latest/install_basic.html

###Get the Control-Repo Deployed On Your Master

At this point you have our control-repo code deployed into your git server. However, we have one final challenge: getting that code onto your puppet master. In the end state the master will pull code from the git server via r10k, however, at this moment your puppet master doesn't have credentials to get code from the git server.

So, we'll set up a deploy key in the git server that will allow a ssh-key we make to deploy the code and configure everything else.

1. On your puppet master, make an ssh key for r10k to connect to gitlab

• /usr/bin/ssh-keygen -t rsa -b 2048 -C 'code_manager' -f /etc/puppetlabs/puppetserver/code_manager.key -q -N ''
• http://doc.gitlab.com/ce/ssh/README.html
• https://help.github.com/articles/generating-ssh-keys/

2. Create a deploy key on the control-repo project in Gitlab

• Paste in the public key from above
• cat /etc/puppetlabs/puppetserver/code_manager.key.pub

3. Login to the PE console
4. Navigate to the Classification page

• Click on the PE Master group
• Click the Classes tab
• Add the puppet_enterprise::profile::master
  • Set the r10k_remote to the ssh url from the front page of your gitlab repo
  • Set the r10k_private_key parameter to /etc/puppetlabs/puppetserver/code_manager.key
• Commit your changes

8. Run puppet agent -t

• Expect to see changes to r10k.yaml

9. Run r10k deploy environment -pv
10. Run puppet agent -t

• Expect to see code manager enabled

10. echo 'code_manager_mv_old_code=true' > /opt/puppetlabs/facter/facts.d/code_manager_mv_old_code.txt
11. Run puppet agent -t

• Now you should see many more changes
• Your code has been deployed with code manager now

Test Code Manager

One of the components setup by this control-repo is that when you "push" code to your git server, the git server will inform the puppet master to deploy branch you just pushed.

1. In one terminal window, tail -f /var/log/puppetlabs/puppetserver/puppetserver.log
2. In a second terminal window

• Add a new file, touch test_file
• git add test_file
• git commit -m "adding a test_file"
• git push origin production

3. Allow the push to complete and then wait a few seconds for everything to sync over

• ls -l /etc/puppetlabs/code/environments/production
  • Confirm test_file is present

4. In your first terminal window review the puppetserver.log to see the type of logging each sync will create

Updating From a Previous Version of PE

Upgrading to PE2015.3.z from PE 2015.2.z

Remove pe_r10k from the PE master group in the console and instead add the following two parameters to the puppet_enterprise::profile::master class under the PE master group.

• r10k_remote = the ssh url for your internal repo
• r10k_private_key = /etc/puppetlabs/puppetserver/code_manager.key

When upgrading the puppet_enterprise::profile::master class has the file_sync_enabled parameter set to false. This parameter should be removed so that code manager can configure file sync.

Finally, you’ll need to echo 'code_manager_mv_old_code=true' > /opt/puppetlabs/facter/facts.d/code_manager_mv_old_code.txt so that my puppet code will redeploy all of your code with code manager.

Appendix

Test The Zack/r10k Webhook

If you are using PE2015.2.z or if you've forced the use of the zack/r10k webhook then you'll want to test that it works.

One of the components setup by this control-repo is that when you "push" code to your git server, the git server will inform the puppet master to run r10k deploy environment -p.

1. Edit README.md

• Just add something to it

2. git add README.md
3. git commit -m "edit README"
4. git push origin production
5. Allow the push to complete and then give it few seconds to complete

• Open /etc/puppetlabs/code/environments/production/README.md and confirm your change is present
