  title: Docker Review Privileges and Install a Plugin
  summary: Read the privileges a plugin demands, install it with those privileges acknowledged, enable it, and confirm it is running.
  description: >-
    Plugin installation is a privilege-granting act, and the Engine API models it
    that way. A plugin can ask for host network access, host mount points, and raw
    devices — so the first call in this flow exists purely to surface what the
    plugin will be granted, and the install call must echo those privileges back as
    an explicit acknowledgement. Installing does not enable: the plugin stays
    inert until the enable call, which is what makes this a real four-step flow.
    Every step spells out its request inline so the flow can be read and executed
    without opening the underlying OpenAPI description.

  summary: Inspect a plugin's requested privileges, install it, enable it, and verify.
  description: >-
    Fetches the privilege set a remote plugin requires, pulls and installs the
    plugin while acknowledging those privileges, enables it, and inspects it to
    confirm the daemon reports it enabled.
  inputs:
    type: object
    required:
    - remote
    - localName
    properties:
      remote:
        type: string
        description: Remote reference for the plugin to install (e.g. "vieux/sshfs:latest").
      localName:
        type: string
        description: Local name to give the installed plugin.
      privileges:
        type: array
        description: >-
          The privilege set to acknowledge on install. This should be the value read
          back from the privileges step, reviewed by a human or a policy check before
          being echoed here.
        items:
          type: object
      enableTimeout:
        type: integer
        description: HTTP client timeout in seconds for the enable call.
      registryAuth:
        type: string
        description: Base64url-encoded auth configuration for pulling from a private registry.
  steps:
  - stepId: readPrivileges
    description: >-
      Read what the plugin is asking for before installing anything. The response
      enumerates each privilege — network mode, mount points, devices, capabilities
      — and is the natural place to gate on policy or human review.
    operationId: GetPluginPrivileges
    parameters:
    - name: remote
      in: query
      value: $inputs.remote
    successCriteria:
    - condition: $statusCode == 200
    outputs:
      requestedPrivileges: $response.body
  - stepId: installPlugin
    description: >-
      Pull and install the plugin, echoing the reviewed privilege set back in the
      body as an explicit acknowledgement of what is being granted. The plugin is
      installed but inert after this call.
    operationId: PluginPull
    parameters:
    - name: remote
      in: query
      value: $inputs.remote
    - name: name
      in: query
      value: $inputs.localName
    - name: X-Registry-Auth
      in: header
      value: $inputs.registryAuth
    requestBody:
      contentType: application/json
      payload: $inputs.privileges
    successCriteria:
    - condition: $statusCode == 204
  - stepId: enablePlugin
    description: >-
      Enable the installed plugin. Installation alone does not activate a plugin —
      until this call it is present but does nothing.
    operationId: PluginEnable
    parameters:
    - name: name
      in: path
      value: $inputs.localName
    - name: timeout
      in: query
      value: $inputs.enableTimeout
    successCriteria:
    - condition: $statusCode == 200
  - stepId: verifyPlugin
    description: >-
      Inspect the plugin to confirm the daemon reports it enabled, and capture the
      settings it was actually granted so they can be reconciled against what was
      requested in the first step.
    operationId: PluginInspect
    parameters:
    - name: name
