PuppetDB 5.0: Resources endpoint

This version of PuppetDB is not included in Puppet Enterprise. The latest version of PE includes PuppetDB 4.4. A newer version is available; see the version menu above for details.

You can query resources by making an HTTP request to the /resources endpoint.

/pdb/query/v4/resources

This will return all resources matching the given query. Resources for deactivated nodes are not included in the response.

URL parameters

  • query: optional. A JSON array of query predicates, in prefix notation (["<OPERATOR>", "<FIELD>", "<VALUE>"]). See the sections below for the supported operators and fields. For general info about queries, see our guide to query structure.

If no query is provided, all resources will be returned.

Note: This endpoint supports dot notation on the parameters field.

Query operators

See the AST query language page for the full list of available operators. Note that:

  • The inequality operators are only supported for the line field.

Query fields

  • tag (string): a case-insensitive tag on the resource. (Appears in the response as tags, which is an array of strings.)

  • certname (string): the name of the node associated with the resource.

  • [parameter, <PARAMETER NAME>] (string): the value of the <PARAMETER NAME> parameter of the resource.

  • type (string, with first letter always capitalized): the resource type.

  • title (string): the resource title.

  • exported (Boolean): whether or not the resource is exported.

  • file (string): the manifest file in which the resource was declared.

  • line (number): the line of the manifest on which the resource was declared.

  • environment (string): the environment of the node associated to the resource.

  • resource (string): a SHA-1 hash of the resource’s type, title, and parameters, for identification.

  • parameters (json): a JSON hash of the resource’s parameters.

Subquery relationships

The following list contains related entities that can be used to constrain the result set using implicit subqueries. For more information, consult the documentation for subqueries.

  • catalogs: the catalog containing a resource.
  • environments: the environment associated with a resource.
  • nodes: the node associated with a resource.

Response format

An array of zero or more resource objects, with each object having the following form:

{
  "certname": "the certname of the associated host",
   "resource": "the resource's unique hash",
   "type": "File",
   "title": "/etc/hosts",
   "exported": "true",
   "tags": ["foo", "bar"],
   "file": "/etc/puppetlabs/code/environments/production/manifests/site.pp",
   "line": "1",
   "environment": "production",
   "parameters": {<parameter>: <value>,
                  <parameter>: <value>,
                  ...}
}

Examples

For file resources tagged “magical”, on any host except for “example.local,” the JSON query structure would be:

["and", ["not", ["=", "certname", "example.local"]],
        ["=", "type", "File"],
        ["=", "tag", "magical"],
        ["=", ["parameter", "ensure"], "enabled"]]

/pdb/query/v4/resources/<TYPE>

This will return all resources for all nodes with the given type. Resources from deactivated nodes aren’t included in the response.

This behaves exactly like a call to /pdb/query/v4/resources with a query string of ["=", "type", "<TYPE>"].

URL parameters / query operators / query fields / response format

This route is an extension of the resources endpoint. It uses the same parameters, operators, fields, and response format.

If you provide a query parameter, it will specify additional criteria, which will be used to return a subset of the information normally returned by this route.

Examples

Using curl from localhost:

curl -X GET http://localhost:8080/pdb/query/v4/resources/User

[{"parameters" : {
    "uid" : "1000,
    "shell" : "/bin/bash",
    "managehome" : false,
    "gid" : "1000,
    "home" : "/home/foo,
    "groups" : "users,
    "ensure" : "present"
  },
  "line" : 10,
  "file" : "/etc/puppetlabs/code/environments/production/manifests/site.pp",
  "exported" : false,
  "environment": "production",
  "tags" : [ "foo", "bar" ],
  "title" : "foo",

curl -X GET http://localhost:8080/pdb/query/v4/resources -d 'query=["=","parameters.groups", "users"]'

[{"parameters" : {

/pdb/query/v4/resources/<TYPE>/<TITLE>

This will return all resources for all nodes with the given type and title. Resources from deactivated nodes aren’t included in the response.

This behaves exactly like a call to /pdb/query/v4/resources with a query string of:

["and",
    ["=", "type", "<TYPE>"],
    ["=", "title", "<TITLE>"]]

Paging

This query endpoint supports paged results via the common PuppetDB paging URL parameters. For more information, please see the documentation on paging.
