Puppet Enterprise 2019.1

Once you've installed PE or the client tools package, there are a few tasks you need to do to prepare your PE infrastructure for orchestration services.

  • Set PE RBAC permissions and token authentication for Puppet orchestrator
  • Enable cached catalogs for use with the orchestrator (optional)
  • Review the orchestrator configuration files and adjust them as needed

All of these instructions assume that PE client tools are installed.

Orchestration services settings

global.conf: Global logging and SSL settings

/etc/puppetlabs/orchestration-services/conf.d/global.conf contains settings shared across the Puppet Enterprise (PE) orchestration services.

The file global.certs typically requires no changes and contains the following settings:
SettingDefinitionDefault
ssl-cert Certificate file path for the orchestrator host. /etc/puppetlabs/orchestration-services/ssl/<orchestrator-host-fqdn>.cert.pem
ssl-key Private key path for the orchestrator host. /etc/puppetlabs/orchestration-services/ssl/<orchestrator-host-fqdn>.private_key.pem
ssl-ca-cert CA file path /etc/puppetlabs/puppet/ssl/ca.pem
The file global.logging-config is a path to logback.xml file that configures logging for most of the orchestration services. See http://logback.qos.ch/manual/configuration.html for documentation on the structure of the logback.xml file. It configures the log location, rotation, and formatting for the following:
  • orchestration-services (appender section F1)
  • orchestration-services status (STATUS)
  • pcp-broker (PCP)
  • pcp-broker access (PCP_ACCESS)
  • aggregate-node-count (AGG_NODE_COUNT)

bootstrap.cfg: Allow list of trapperkeeper services to start

/etc/puppetlabs/orchestration-services/bootstrap.cfg is the list of trapperkeeper services from the orchestrator and pcp-broker projects that are loaded when the pe-orchestration-services system service starts.
  • To disable a service in this list, remove it or comment it with a # character and restart pe-orchestration-services
  • To enable an NREPL service for debugging, add puppetlabs.trapperkeeper.services.nrepl.nrepl-service/nrepl-service to this list and restart pe-orchestration-services.

webserver.conf and web-routes.conf: The pcp-broker and orchestrator HTTP services

/etc/puppetlabs/orchestration-services/conf.d/webserver.conf describes how and where to the run pcp-broker and orchestrator web services, which accept HTTP API requests from the rest of the PE installation and from external nodes and users.

The file webserver.orchestrator configures the orchestrator web service. Defaults are as follows:

SettingDefinitionDefault
access-log-config A logback XML file configuring logging for orchestrator access messages. /etc/puppetlabs/orchestration-services/request-logging.xml
client-auth Determines the mode that the server uses to validate the client's certificate for incoming SSL connections. want or need
default-server Allows multi-server configurations to run operations without specifying a server-id. Without a server-id, operations will run on the selected default. Optional. true
ssl-ca-cert Sets the path to the CA certificate PEM file used for client authentication. /etc/puppetlabs/puppet/ssl/certs/ca.pem
ssl-cert Sets the path to the server certificate PEM file used by the web service for HTTPS. /etc/puppetlabs/orchestration-services/ssl/<orchestrator-host-fqdn>.cert.pem
ssl-crl-path Describes a path to a Certificate Revocation List file. Optional. /etc/puppetlabs/puppet/ssl/crl.pem
ssl-host Sets the host name to listen on for encrypted HTTPS traffic. 0.0.0.0.
ssl-key Sets the path to the private key PEM file that corresponds with the ssl-cert /etc/puppetlabs/orchestration-services/ssl/<orchestrator-host-fqdn>.private_key.pem
ssl-port Sets the port to use for encrypted HTTPS traffic. 8143

The file webserver.pcp-broker configures the pcp-broker web service. Defaults are as follows:

SettingDefinitionDefault

Setting PE RBAC permissions and token authentication for orchestrator

Before you run any orchestrator jobs, you need to set the appropriate permissions in PE role-based access control (RBAC) and establish token-based authentication.

Most orchestrator users require the following permissions to run orchestrator jobs or tasks:

Type Permission Definition
Puppet agent Run Puppet on agent nodes. The ability to run Puppet on nodes using the console or orchestrator. Instance must always be "*".
Job orchestratorStart, stop and view jobsThe ability to start and stop jobs and tasks, view jobs and job progress, and view an inventory of nodes that are connected to the PCP broker.
TasksRun tasksThe ability to run specific tasks on all nodes, a selected node group, or nodes that match a PQL query.
Nodes View node data from PuppetDB. The ability to view node data imported from PuppetDB. Object must always be "*".

Note: If you do not have permissions to view a node group, or the node group doesn't have any matching nodes, that node group won't be listed as an option for viewing. In addition, a node group does not appear if no rules have been specified for it.

Assign task permissions to a user role

  1. In the console, click Access control > User roles.

  2. From the list of user roles, click the one you want to have task permissions.

  3. On the Permissions tab, in the Type box, select Tasks.

  4. For Permission, select Run tasks, and then select a task from the Object list. For example, facter_task.

  5. Click Add permission, and then commit the change.

Using token authentication

Before running an orchestrator job, you must generate an RBAC access token to authenticate to the orchestration service. If you attempt to run a job without a token, PE prompts you to supply credentials.

For information about generating a token with the CLI, see the documentation on token-based authentication.

Enable cached catalogs for use with the orchestrator (optional)

Enabling cached catalogs on your agents ensures Puppet does enforce any catalog changes on your agents until you run an orchestrator job to enforce changes.

When you use the orchestrator to enforce change in a Puppet environment (for example, in the production environment), you want the agents in that environment to rely on their cached catalogs until you run an orchestrator job that includes configuration changes for those agents. Agents in such environments check in during the run interval (30 minutes by default) to reinforce configuration in their cached catalogs, and apply new configuration only when you run Puppet with an orchestration job.

Note: This is an optional configuration. You can run Puppet on nodes with the orchestrator in workflows that don't require cached catalogs.
  1. Run Puppet on the new agents.
    Important: Be sure you run Puppet on the new agents before assigning any application components to them or performing the next step.
  2. In each agent's puppet.conf file, in the [agent]section, add use_cached_catalog=true. To complete this step, choose one of the following methods:
    • From the command line on each agent machine, run the following command:
      puppet config set use_cached_catalog true --section agent
    • Add an ini_setting resource in the node default {} section of the environment’s site.pp. This adds the setting to all agents in that environment.  
      if $facts['kernel'] = 'windows' {
        $config = 'C:/ProgramData/PuppetLabs/puppet/etc/puppet.conf'
      } else {
        $config = $settings::config
      }
       
      ini_setting { 'use_cached_catalog':
        ensure  => present,
        path    => $config,
        section => 'agent',
        setting => 'use_cached_catalog',
        value   => 'true',
      }
  3. Run Puppet on the agents again to enforce this configuration.

Orchestrator configuration files

The configuration file for the orchestrator allows you to run commands from the CLI without having to pass additional flags. Whether you are running the orchestrator from the Puppet master or from a separate work station, there are two types of configuration files: a global configuration file and a user-specified configuration file.

Orchestrator global configuration file

If you're running the orchestrator from a PE-managed machine, on either the Puppet master or an agent node, PE manages the global configuration file.

This file is installed on both managed and non-managed workstations at:

  • *nix systems --- /etc/puppetlabs/client-tools/orchestrator.conf
  • Windows --- C:/ProgramData/PuppetLabs/client-tools/orchestrator.conf

The class that manages the global configuration file is puppet_enterprise::profile::controller. The following parameters and values are available for this class:

Parameter Value
manage_orchestrator true or false (default is true)
orchestrator_url url and port (default is Puppet master url and port 8143)

The only value PE sets in the global configuration file is the orchestrator_url (which sets the orchestrator's service-url in /etc/puppetlabs/client-tools/orchestrator.conf).

Important: If you're using a managed workstation, do not edit or change the global configuration file. If you're using an unmanaged workstation, you can edit this file as needed.

Orchestrator user-specified configuration file

You can manually create a user-specified configuration file and populate it with orchestrator configuration file settings. PE does not manage this file.

This file needs to be located at ~/.puppetlabs/client-tools/orchestrator.conf for both *nix and Windows.

If present, the user specified configuration always takes precedence over the global configuration file. For example, if both files have contradictory settings for the environment, the user specified settings prevail.

Orchestrator configuration file settings

The orchestrator configuration file is formatted in JSON. For example:

{
  "options" : {
    "service-url": "https://<PUPPET MASTER HOSTNAME>:8143",
    "cacert": "/etc/puppetlabs/puppet/ssl/certs/ca.pem",
    "token-file": "~/.puppetlabs/token",
    "color": true,
  }
}

The orchestrator configuration files (the user-specified or global files) can take the following settings:

SettingDefinition
service-urlThe URL that points to the Puppet master and the port used to communicate with the orchestration service. (You can set this with the orchestrator_url parameter in the puppet_enterprise::profile::controller class.) Default value: https://<PUPPET MASTER HOSTNAME>:8143
environmentThe environment used when you issue commands with Puppet orchestrator.
cacertThe path for the Puppet Enterprise CA cert.
  • *nix: /etc/puppetlabs/puppet/ssl/certs/ca.pem

  • Windows: C:\ProgramData\PuppetLabs\puppet\etc\ssl\certs\ca.pem

token-fileThe location for the authentication token. Default value: ~/.puppetlabs/token
colorDetermines whether the orchestrator output uses color. Set to true or false.
noopDetermines whether the orchestrator should run the Puppet agent in no-op mode. Set to true or false.

PE Bolt services configuration

The PE Bolt server is a Ruby service that enables SSH and WinRM tasks from the console. The server accepts requests from the orchestrator, calls out to Bolt to run the task, and returns the result.

PE Bolt server configuration

The PE Bolt server provides an API for running tasks over SSH and WinRM using Bolt, which is the technology underlying PE tasks. The API server for tasks is available as pe-bolt-server.

The server is a Puma application that runs as a standalone service.

The server is configured in /etc/puppetlabs/bolt-server/conf.d/bolt-server.conf, managed by the puppet_enterprise::profile::bolt_server class, which includes these parameters:
SettingTypeDescriptionDefault
bolt_server_loglevel string Bolt log level. Acceptable values are debug, info, notice, warn, and error. notice
