Puppet Enterprise 2019.0

Puppet Enterprise includes preconfigured node groups that are used to manage your configuration.

All Nodes node group

This node group is at the top of the hierarchy tree. All other node groups stem from this node group.

Classes
No default classes. Avoid adding classes to this node group.
Matching nodes
All nodes.
Notes
You can't modify the preconfigured rule that matches all nodes.

Infrastructure node groups

Infrastructure node groups are used to manage PE.

Important: Don't make changes to infrastructure node groups other than pinning new nodes for documented functions, like creating compile masters. If you want to add custom classifications to infrastructure nodes, create new child groups and apply classification there.

PE Infrastructure node group

This node group is the parent to all other infrastructure node groups.

The PE Infrastructure node group contains data such as the hostnames and ports of various services and database info (except for passwords).

It's very important to correctly configure the puppet_enterprise class in this node group. The parameters set in this class affect the behavior of all other preconfigured node groups that use classes starting with puppet_enterprise::profile. Incorrect configuration of this class could potentially cause a service outage.

CAUTION: Never remove the PE Infrastructure node group. Removing the PE Infrastructure node group disrupts communication between all of your PE Infrastructure nodes.
Classes
puppet_enterprise — sets the default parameters for child node groups
Matching nodes
Nodes are not pinned to this node group. The PE Infrastructure node group is the parent to other infrastructure node groups, such as PE Master, and is only used to set classification that all child node groups inherit. Never pin nodes directly to this node group.

These are the parameters for the puppet_enterprise class, where <YOUR HOST> is your master certname. You can find the certname with puppet config print certname.

ParameterValue
database_host "<YOUR HOST>"
puppetdb_host "<YOUR HOST>"
database_port

"<YOUR PORT NUMBER>"

Required only if you changed the port number from the default 5432.

database_ssl true if you're using the PE-installed PostgreSQL, and false if you're using your own PostgreSQL.
puppet_master_host "<YOUR HOST>"
certificate_authority_host "<YOUR HOST>"
console_port

"<YOUR PORT NUMBER>"

Required only if you changed the port number from the default 443.)

puppetdb_database_name "pe-puppetdb"
puppetdb_database_user "pe-puppetdb"
puppetdb_port

"<YOUR PORT NUMBER>"

Required only if you changed the port number from the default 8081.)

console_host "<YOUR HOST>"
pcp_broker_host "<YOUR HOST>"

PE Certificate Authority node group

This node group is used to manage the certificate authority.

Classes
puppet_enterprise::profile::certificate_authority — manages the certificate authority on the first master node
Matching nodes
On a new install, the master is pinned to this node group.
Notes
Don't add additional nodes to this node group.

PE Master node group

This node group is used to manage masters and add compile masters.

Classes
  • puppet_enterprise::profile::master — manages the Puppet master service
Matching nodes
On a new install, the master is pinned to this node group.

PE Orchestrator node group

This node group is used to manage the application orchestration service.

Classes
puppet_enterprise::profile::orchestrator — manages the application orchestration service
Matching nodes
On a new install, the master is pinned to this node group.
Notes
Don't add additional nodes to this node group.

PE PuppetDB node group

This node group is used to manage the database service.

Classes
puppet_enterprise::profile::puppetdb — manages the PuppetDB service
Matching nodes
On a new install, the PuppetDB server node is pinned to this node group.
Notes
Don't add additional nodes to this node group.

PE Console node group

This node group is used to manage the console.

Classes
  • puppet_enterprise::profile::console — manages the console, node classifier, and RBAC
  • puppet_enterprise::license — manages the PE license file for the status indicator
Matching nodes
On a new install, the console server node is pinned to this node group.
Notes
Don't add additional nodes to this node group.

PE Agent node group

This node group is used to manage the configuration of agents.

Classes
puppet_enterprise::profile::agent — manages your agent configuration
Matching nodes
All managed nodes are pinned to this node group by default.

PE Infrastructure Agent node group

This node group is a subset of the PE Agent node group used to manage infrastructure-specific overrides.

Classes
puppet_enterprise::profile::agent — manages your agent configuration
Matching nodes
All nodes used to run your Puppet infrastructure and managed by the PE installer are pinned to this node group by default, including the master, PuppetDB, console, and compile masters.
Notes
You might want to manually pin to this group any additional nodes used to run your infrastructure, such as compile master load balancer nodes. Pinning a compile master load balancer node to this group allows it to receive its catalog from the master of masters, rather than the compile master, which helps ensure availability.

PE Database node group

This node group is used to manage the PostgreSQL service.

Classes
  • puppet_enterprise::profile::database — manages the PE-PostgreSQL service
Matching nodes
The node specified as puppet_enterprise::database_host is pinned to this group. By default, the database host is the PuppetDB server node.
Notes
Don't add additional nodes to this node group.

Environment node groups

Environment node groups are used only to set environments. They should not contain any classification.

Environment node groups force all matching nodes into the group's environment, even if those nodes match another node group that specifies a different environment. This workflow avoids the environment conflicts that can happen when you unintentionally have nodes that match multiple node groups with conflicting environments.

Note: Don't uncheck This is an environment group for these preconfigured environment node groups.

Production environment node group

Nodes in this group will be assigned to the production environment.

Classes
You should never add any classes to this group. This group should only be used to set the production environment for matching nodes.
Matching nodes
This group comes with a rule that matches all nodes.
Notes
The This is an environment group option must be selected in the node group metadata section.

Agent-specified environment node group

Normally, an environment specified by the node classifier overrides any environment set in a node's own puppet.conf file (the agent-specified environment). However, sometimes you might want to let an agent specify its own environment, such as in an environment-based testing workflow.

The agent-specified environment node group forces the environment specified in a node's puppet.conf file, ignoring any environments that have been set by the node classifier. If you want to use the agent-specified environment for a node, you should pin the node to this node group, or create a rule in the node group that matches the node.

Classes
Don't add any classes to this group. This group should only be used to set the agent-specified environment for matching nodes.
Matching nodes
By default, this group matches no nodes. Create rules to match nodes that should be assigned the agent-specified environment. Alternatively, you can manually pin the nodes to the group.
Notes
The This is an environment group option must be selected in the node group metadata section.
