There’s no armv7l packages of the puppet agent, so I need to run it from source.
I’ll be looking to run the following client version to match my PE install.
# puppet --version 4.10.12
Applicable requirements come from 4.10.
- Ruby: We currently only test and package with 2.1.x versions of Ruby.
- Facter 3.1 or later
- Hiera 2.0.0 or later
- The json gem (any modern version)
- The rgen gem version 0.6.6 or later is now required because Puppet parser = future is enabled by default
- Optional libraries: The msgpack gem is required if you are using msgpack serialization.
Centos 7 has Ruby 2.0.0 as the primary package; might be other versions hidden under other names or in software collections, but for the moment, I can live with:
Warning: Support for ruby version 2.0.0 is deprecated and will be removed in a future release.
Some packages are needed.
- Bundler pulls in Ruby.
- git is needed to pull down the repo, this also installs perl and rsync.
- ruby-devel is also needed for compiling gems
- .. as are gcc and make.
yum install rubygem-bundler git ruby-devel gcc make

Pull down the release
I initially pulled down a tar ball, but then switched to git; it’ll be easier for changing client versions as needed.
There’s loads of tags for different releases, but to avoid detached HEAD, I’ll start with an existing branch.
Created an account so all this stuff happens under a non-root account.
useradd --create-home --shell /sbin/nologin --uid 1042 --user-group puppeteer sudo -u puppeteer bash cd ~/ mkdir puppetsrc git clone git://github.com/puppetlabs/puppet puppetsrc cd puppetsrc/
There’s some branches .. so we could run with the latest 4.10.x ..
$ git branch --remote origin/3.x origin/4.10.x origin/5.3.x origin/5.4.x origin/5.5.x origin/6.0.x origin/6.1.x origin/HEAD -> origin/master origin/master origin/vault $ git checkout 4.10.x
.. which is a good starting point.
Or, if you want to go direct to a specific version, check out a tag.
$ git checkout 4.10.12
To avoid ‘detached HEAD’, create a local branch based on the tag.
$ git checkout -b 4.10.12 4.10.12
Most/all commands from this point run with a working directory of ~puppeteer/puppetsrc – whether
- run by root (eg: bundle exec puppet agent) or
- puppeteer – bundle install etc.
The instructions refer to a .bundle directory within the source tree as, I imagined, a target for stuff to be downloaded. If so that would suggest ..
$ cd puppetsrc $ grep .bundle .gitignore .bundle/ .bundle/ acceptance/.bundle
Final clean run (4.10.x) looked like this.

You can auto-configure YARD to automatically build the yri index for installed gems by typing: $ yard config --gem-install-yri See `yard config --help` for more information on RubyGems install hooks. You can also add the following to your .gemspec to have YARD document your gem on install: spec.metadata["yard.run"] = "yri" # use "yard" to build full HTML docs. -------------------------------------------------------------------------------- $ bundle exec puppet --version 4.10.14
The following checks out a tag as a branch, and then the gems are rebuilt as needed.
git checkout -b 4.10.12 4.10.12 bundle update
Deltas rolling back 4.10.x to 4.10.12 were:
Installing rake 10.1.1 (was 12.3.2) Using puppet 4.10.12 (was 4.10.14) from source at .
Getting us where we wanted to be.
$ bundle exec puppet --version 4.10.12
Set up certificate signing, and fire up the client.
# as root /bin/mkdir -p /etc/puppetlabs/puppet && \ cat >> /etc/puppetlabs/puppet/csr_attributes.yaml <<EOF extension_requests: pp_environment: dev pp_role: role::pitest EOF cd /home/puppeteer/puppetsrc bundle exec puppet agent --test --waitforcert 20 --certname=$(hostname -f) \ --server=puppet.$(hostname -d) --environment=development
Which worked. It waited for my puppet master to start up, then for me to sign the cert. The role wasn’t defined, so my manifests/site.pp abended the catalog run, but otherwise working as designed.
It’ll save a little typing later if I also provide:
# as root cat >> /etc/puppetlabs/puppet/puppet.conf <<EOF [main] certname = $(hostname -f) server = puppet.$(hostname -d) environment = development EOF
Once the catalog is working, the relevant profile will manage that config anyway.
- Testing my existing profiles on this installation
- Adding profiles to handle this minimal build and pi nuances
- Do some actual stuff with the machine
Running the client regularly: I’ll do it out of cron to save memory. ‘bundle exec’ is clearly not how it is normally run, so my beginners ruby will need to do some heavy lifting and find a nicer way.
In the first instance, though, I want to get some things running on my new Pis, so running puppet manually to get the build in place isn’t a big deal.
bootnote: rspec tests
I tried running the test suite.
bundle exec rspec spec [..] Finished in 18 minutes 38 seconds (files took 4 minutes 11.9 seconds to load) 1103 examples, 0 failures, 5 pending
I had to terminate it early as it kicks off a bunch of parallel processes and then causes the machine to swap like crazy.
