This is the main repo for my GIT Workshop at PuppetConf 2014. http://sched.co/1nwrtol
1. Install Puppet
Although really you should have it installed on your local machine already.
2. Install puppet-lint
gem install puppet-lint
3. Install Virtualbox
This vagrant setup requires one of the following versions: 4.0, 4.1, 4.2. The latest Virtualbox version is 4.3
4. Install Vagrant
Latest version, 1.5.6 when this repo was created, will work fine.
5. GIT clone this repo
git clone https://github.com/terrimonster/gitworkshop.git
6. cd gitworkshop
7. vagrant up
Get yourself a coffee and a snack. This is going to take awhile. Vagrant is provisioning the instances xmaster, gitlab, and testagent.
If you destroy (vagrant destroy ) the vagrant VMs and rebuild, the provisioning process won't take nearly as long because you'll already have downloaded the Puppet Enterprise installation file.
8. Set up the gitlab server
Login to the Gitlab web interface at: http://192.168.137.11 (default)
The default credentials are:
You will be prompted immediately to change the root password.
8.1 Create a new "group" in Gitlab called
8.2 Create a new project in Gitlab with the following settings:
8.3 Add an SSH key to Gitlab
Go to the "profile settings" in Gitlab and click on "SSH Keys"
Add a public SSH key from your local machine
8.4 Get the mymotd code
On your local machine, clone the example mymotd module:
git clone https://github.com/terrimonster/mymotd.git cd mymotd rm -rf .git
Now the code is not a git working directory. Let's make that into a repo for your GitLab server. While still inside that mymotd directory:
git init git add . git commit -m "Initial commit" git remote add origin firstname.lastname@example.org:puppet/mymotd.git git push origin master
You should then be able to see the pushed code in the Gitlab repositories.
8.5 Add the pre-commit hook to your local repository
cd mymotd cp hooks/pre-commit .git/hooks/ chmod 755 .git/hooks/pre-commit
Introduce an error into mymotd/manifests/init.pp, then try to add and commit the file. You will have a result somewhat like below.
vi manifests/init.pp git add manifests/init.pp git commit -m 'error' Validating manifests/init.pp... Error: Could not parse for environment production: Syntax error at 'owner'; expected '}' at mymotd/manifests/init.pp:6 [master df572b4] error 1 file changed, 1 insertion(+), 1 deletion(-)
Fix the error(s) and re-attempt committing and pushing the file.
8.6 Add the pre-receive hook to the mymotd repo
SSH into the GitLab server, copy the hooks in the vagrant directory to the mymotd directory, and make the pre-receive hook executable:
vagrant ssh gitlab sudo su - cp -r /vagrant/hooks /var/opt/gitlab/git-data/repositories/puppet/mymotd.git/ chmod a+x /var/opt/gitlab/git-data/repositories/puppet/mymotd.git/hooks/pre-receive
Delete the pre-commit hook from your local repository:
Re-introduce an error into the manifests/init.pp file. You should see a result like below:
vi manifests/init.pp git add manifests/init.pp git commit -m 're-introducing error' [master d66d298] re-introducing error 1 file changed, 2 insertions(+), 2 deletions(-) git push origin master Counting objects: 7, done. Delta compression using up to 4 threads. Compressing objects: 100% (3/3), done. Writing objects: 100% (4/4), 358 bytes | 0 bytes/s, done. Total 4 (delta 2), reused 0 (delta 0) remote: Checking puppet manifest syntax for manifests/init.pp... remote: Error: Could not parse for environment production: Syntax error at 'owner'; expected '}' at /tmp/mymotd/manifests/init.pp:6 remote: Error: puppet syntax error in manifests/init.pp (see above) remote: Error: 1 syntax error(s) found in puppet manifests. Commit will be aborted. remote: puppet-lint not installed. Skipping puppet-lint tests... remote: Error: 1 subhooks failed. Declining push. To email@example.com:puppet/mymotd.git ! [remote rejected] master -> master (pre-receive hook declined) error: failed to push some refs to 'firstname.lastname@example.org:puppet/mymotd.git'
9. Add the master's SSH key to the GitLab Server
vagrant ssh xmaster sudo su - cat ~/.ssh/id_rsa.pub
Copy the output and paste it into a new SSH key entry in Gitlab.
10. Clone the mymotd to the master's module directory
vagrant ssh xmaster sudo su - cd /etc/puppetlabs/puppet/environments/production/modules git clone email@example.com:puppet/mymotd.git
11. Classify node default with mymotd
vagrant ssh xmaster sudo su - vi /etc/puppetlabs/puppet/environments/production/manifests/site.pp
Delete the comment to enable mymotd on node default.
12. Run puppet on testagent
vagrant ssh testagent sudo su - puppet agent -t
This makes use of Greg Sarjeant's data-driven-vagrantfile

No Vagrant plugins are required.
