Admin commands endpoint

Sections

The /cmd endpoint can be used to trigger PuppetDB maintenance operations or to directly delete a node. Admin commands are processed synchronously seperate from other PuppetDB commands.

POST /pdb/admin/v1/cmd

Admin commands must be triggered by a POST.

Request format

The POST request should specify Content-Type: application/json and the request body should look like this:

{"command": "...",
 "version": 123,
 "payload": <json object>}

command is a string identifying the command.

version is a JSON integer describing what version of the given command you’re attempting to invoke. The version of the command also indicates the version of the wire format to use for the command.

payload must be a valid JSON object of any sort. It’s up to an individual handler function to determine how to interpret that object.

URL parameters

  • The POST endpoint accepts no URL parameters.

List of admin commands

“clean”, version 1

{"command" : "clean",
 "version" : 1,
 "payload" : [REQUESTED_OPERATION, ...]}

where valid REQUESTED_OPERATIONs are "expire_nodes", "purge_nodes", "purge_reports", "gc_packages", and "other". In addition, a purge_nodes operation can be structured like this to specify a batch_limit:

["purge_nodes" {"batch_limit" : 50}]

When specified, the batch_limit restricts the maximum number of nodes purged to the value specified, and if not specified, the limit will be the node-purge-gc-batch-limit.

An empty payload vector requests all maintenance operations.

Response format

The response type will be application/json, and upon success will include this JSON map:

{"ok": true}

Only one maintenance operation can be running at a time. If any other maintenance operation is already in progress the HTTP response status will be 409 (conflict), will include a map like this

{"kind": "conflict",
 "msg": "Another cleanup is already in progress",
 "details": null}

and no additional maintenance will be performed. The msg and details may or may not vary, but the kind will always be “conflict”.

Example

Using curl from localhost:

$ curl -X POST http://localhost:8080/pdb/admin/v1/cmd \
       -H 'Accept: application/json' \
       -H 'Content-Type: application/json' \
       -d '{"command": "clean",
            "version": 1,
            "payload": ["expire_nodes", "purge_nodes"]}'
{"ok": true}

“delete”, version 1

{"command" : "delete",
 "version" : 1,
 "payload" : {"certname" : <string>}}

The "delete" command can be used to trigger the immediate deletion of all data associated with a certname. It is important to note that the delete operation doesn’t account for commands which may be in the command queue but not yet processed by PuppetDB. This could cause a node targeted for deletion to reappear when the command in the queue gets processed after the deletion operation has run.

Response format

The response type will be application/json, and upon success will include this JSON map:

{"deleted": "certname"}

Example

Using curl from localhost:

$ curl -X POST http://localhost:8080/pdb/admin/v1/cmd \
       -H 'Accept: application/json' \
       -H 'Content-Type: application/json' \
       -d '{"command": "delete",
            "version": 1,
            "payload": {"certname" : "node-1"}}'
{"deleted": "node-1"}
