puppetwash

A Wash plugin for managing your Puppet instances (both PE and open source). This plugin will iterate all nodes from PuppetDB and expose information about them such as their facts, last run report, and the current catalog.

wash . ❯ stree puppet
puppet
└── [instance]
    └── nodes
        └── [node]
            ├── catalog
            ├── facts
            │   └── [fact]
            └── reports
                └── [report]

The Puppetwash plugin lists all your managed nodes that have been reported to PuppetDB.

wash . ❯ ls puppet/instance_one/nodes
base-graham.delivery.puppetlabs.net/
choosy-cat.delivery.puppetlabs.net/
fugual-apology.delivery.puppetlabs.net/
lunar-scoundrel.delivery.puppetlabs.net/
sturdy-romp.delivery.puppetlabs.net/

You can also use it to view the last catalog applied to a given node

wash . ❯ cat puppet/instance_one/nodes/base-graham.delivery.puppetlabs.net/catalog.json
{
  "catalog_uuid": "663da32b-b146-4d7a-8367-52849cb4ed5f",
  "producer": "sturdy-romp.delivery.puppetlabs.net",
  "hash": "ae8bef9977cd10c85a949cb8af97f3d27739bdc9",
...

Or to find all reports that were generated within the last 10 hours

wash . ❯ find puppet -k '*report' -mtime -10h
puppet/instance_one/nodes/base-graham.delivery.puppetlabs.net/reports/2020-02-07T18:26:31.789Z

  {
    "catalog_uuid": "663da32b-b146-4d7a-8367-52849cb4ed5f",
    "receive_time": "2020-02-07T18:26:32.375Z",

...

The puppetwash plugin also represents a node's facts as files, making it easy to search through them.

wash . ❯ ls puppet/instance_one/nodes/base-graham.delivery.puppetlabs.net/facts
aio_agent_build
aio_agent_version
architecture
augeas
augeasversion
...
wash . ❯ cat puppet/instance_one/nodes/base-graham.delivery.puppetlabs.net/facts/aio_agent_build

1. gem install puppetwash

2. Get the path to the puppetwash script with gem contents puppetwash.

3. Add to ~/.puppetlabs/wash/wash.yaml

   external-plugins:
       - script: '/path/to/puppetwash/puppet.rb'
   puppet:
     # Uncomment this to add the 'my_pe_instance' PE instance
     #my_pe_instance:
     #  puppetdb_url: https://puppetmaster.example.com:8081
     #  rbac_token: <my_rbac_token>
     #  cacert: /path/to/cacert.pem # copy this from `puppet config print localcacert` on the master
     #
     # Uncomment this to add the 'my_oss_instance' open source instance
     #my_oss_instance:
     #  puppetdb_url: https://puppetdb.example.com:8081
     #  cacert: /path/to/cacert.pem # maybe /etc/puppetlabs/puppetdb/ssl/certs/ca.pem
     #  cert: /path/to/cert.pem
     #  key: /path/to/key.pem

4. Enjoy!

If you're a developer, you can use the puppetwash plugin from source with bundle install and set script: /path/to/puppetwash/puppet.

The hostname in puppetdb_url should match the master certname, otherwize you will get TLS errors. If you use a master with a non-resolvable certname, you can add an entry to your hosts file:

<my_master_ip> puppetmaster.example.com

• Include facts in node metadata so that you can use find to filter your nodes on their facts
• For PE instances: view tasks + jobs
• Anything else that you think could be useful. Please file an issue!
