Pdksync is an efficient way to run a pdk update
command against the various repositories that we manage — keeping them up-to-date with the changes made to PDK. It is a solution for converted modules that no longer run with modulesync.
Note: This tool creates a 'live' pull request against the master branch of the module it is running against — defined in
managed_modules.yml
. Before running this tool, ensure this file reflects the modules you wish it to run against, and thatconstants.rb
is up-to-date with the correct namespace your modules reside in.
- To use pdksync, clone the GitHub repo or install it as a gem. Set up the environment by exporting a GitHub token:
export GITHUB_TOKEN=<access_token>
- Before the script will run, you need to install the gems:
bundle install --path .bundle/gems/
- Once this is complete, call the built-in rake task to run the module:
bundle exec rake pdksync
Pdksync is a gem that works to clone, update, and push module repositories. It is activated from within the pdksync module.
The gem takes in a file, managed_modules.yml
, stored within the gem that lists all the repositories that need to be updated. It then clones them, one after another, so that a local copy exists. The update command is ran against this local copy, with the subsequent changes being added into a commit on a unique branch. It is then pushed back to the remote master — where the local copy was originally cloned. The commit is merged to the master via a pull request, causing the gem to begin to clone the next repository.
By default, pdksync will supply a label to a PR (default is 'maintenance'). This can be changed by opening lib/pdksync/constants.rb
and modifying the PDKSYNC_LABEL
constant. You must ensure that the label selected exists on the modules that you are applying pdksync to. Should you wish to disable this feature, simply change PDKSYNC_LABEL
to an empty string i.e. ''. Similarly, when supplying a label using the git:push_and_create_pr
rake task, the label must exist on each of the managed modules to run successfully.
The following rake tasks are available with pdksync:
show_config
Display the current configuration of pdksyncgit:clone_managed_modules
Clone managed modules.git:create_commit[:branch_name, :commit_message]
Stage commits for modules, branchname and commit message eg rake 'git:create_commit[flippity, commit messagez]'.git:push_and_create_pr[:pr_title, :label]
Push commit, and create PR for modules. Label is optional eg rake 'git:push_and_create_pr[pr title goes here, optional label right here]'.git:clean[:branch_name]
Clean up origin branches, (branches must include pdksync in their name) eg rake 'git:clean[pdksync_origin_branch]'.pdk:pdk_convert
Runs PDK convert against modules.pdk:pdk_validate
Runs PDK validate against modules.pdksync[:additional_title]
Run full pdksync process, clone repository, pdk update, create pr. Additional information can be added to the title, which will be appended before the reference section.rake pdksync
PR title outputs aspdksync - pdksync_heads/master-0-gabccfb1
rake 'pdksync[MODULES-8231]'
PR title outputs aspdksync - MODULES-8231 - pdksync_heads/master-0-gabccfb1
run_a_command[:command]
Run a command against modules eg rake 'run_a_command[complex command here -f -gx]'
By default pdksync will use hardcoded values for configuring itself however if you wish to override these values, simply create $HOME/.pdksync.yml
and use the following format:
---
namespace: 'puppetlabs'
pdksync_dir: 'modules_pdksync'
push_file_destination: 'origin'
create_pr_against: 'master'
managed_modules: 'managed_modules.yml'
pdksync_label: 'maintenance'
You may override any property. Those that are not specified in your config file will use their corresponding default value from constants.rb
.
It currently runs without additional arguments. To alter how it runs, make alterations to either the constants.rb
or managed_modules.yml
.
This module runs through a pre-set array of modules, with this array set within the managed_modules.yml
file. This file makes use of a simple yaml
style format to set out the different module names, for example:
---
- puppetlabs-motd
- puppetlabs-stdlib
- puppetlabs-mysql
To add a module, add it to the list. To remove a module, remove it from the list. If you wish to specify a custom managed modules file, use the managed_modules
property in your configuration file to specify the path to the file.
If your modules are currently managed by modulesync, and you want to use PDK and keep your modules up-to-date, read the following.
pdk convert
- A command to convert your module, for example, to make it compatible with the PDK.convert_report.txt
- A report that shows the changes PDK will make to your module whenpdk convert
is ran.pdk update
- A command to consume any changes that have been made to the pdk-template used to convert the module.update_report.txt
- A report that shows the changes PDK will make to your module whenpdk update
is ran.pdk validate
- A command to run basic validation checks on your module.pdk test unit
- A command to run all available unit tests on your module..sync.yml
- A file that lists all of of your module customizations — and will require work before module conversion.
- Unit tests are in a good state — with no failures. Check by running
pdk test unit
. - The module is in good shape. Check by running
pdk validate
.
When you're confident everything is in good shape, you can start converting your module to make it compatible with PDK.
- Run
pdk convert --noop
. This will output to the console a high level overview of the changes that PDK is planning to make to your files.
Note: For an in-depth diff, see the convert_report.txt that is output in the module root directory.
- Make changes to your .sync.yml. State any configuration that the custom pdk-templates plan to remove.
Useful commands via the .sync.yml:
- Add additional gem dependencies:
Gemfile:
required:
':system_tests':
- gem 'octokit'
platforms: ruby
- Make changes to your travis configuration:
.travis.yml:
branches:
- release
- Delete files that you don't want to exist in the repo:
.gitlab-ci.yml:
delete: true
- Unmanage files that you don't want to be managed:
.gitlab-ci.yml:
unmanaged: true
Note: It is unlikely your module will work out of the box.
-
When you are finished customizing your .sync.yml file, run
pdk convert --noop
and confirm the changes that PDK will make when you convert. Changes can be found in theconvert_report.txt
-
Run
pdk convert
to convert. You will be prompted to pass in Y/N — type Y and all your changes will be applied.
Note: If you have any concerns it is not too late — type N.
-
Run your unit tests to confirm that nothing has broken. If there are breakages, you might need to require a library or include a missing gem — address this issue before you continue.
-
Run
pdk validate
to ensure there are no failures. -
Commit the changes that the
pdk convert
has made and create your pull request. -
Remove your module from being managed via
modulesync
, and start usingpdksync
going forward — no more manually creating pull requests.

This tool has been developed and tested on OSX and Linux. It currently does not run on Windows.
