# Allocations HTTP API

The `/allocation` endpoints are used to query for and interact with allocations.

## List Allocations

This endpoint lists all allocations.

| Method | Path              | Produces           |
| ------ | ----------------- | ------------------ |
| `GET`  | `/v1/allocations` | `application/json` |

The table below shows this endpoint's support for
[blocking queries](/api-docs#blocking-queries) and
[required ACLs](/api-docs#acls).

| Blocking Queries | ACL Required         |
| ---------------- | -------------------- |
| `YES`            | `namespace:read-job` |

### Parameters

- `prefix` `(string: "")`- Specifies a string to filter allocations based on an
  ID prefix. Because the value is decoded to bytes, the prefix must have an
  even number of hexadecimal characters (0-9a-f). This is specified as a query
  string parameter.

- `next_token` `(string: "")` - This endpoint supports paging. The `next_token`
  parameter accepts a string which identifies the next expected allocation.
  This value can be obtained from the `X-Nomad-NextToken` header from the
  previous response.

- `per_page` `(int: 0)` - Specifies a maximum number of allocations to return
  for this request. If omitted, the response is not paginated. The value of the
  `X-Nomad-NextToken` header of the last response can be used as the
  `next_token` of the next request to fetch additional pages.

- `filter` `(string: "")` - Specifies the [expression](/api-docs#filtering)
  used to filter the results. Consider using pagination or a query parameter to
  reduce resource used to serve the request.

- `namespace` `(string: "default")` - Specifies the namespace to search. Specifying
  `*` would return all allocations across all the authorized namespaces.

- `resources` `(bool: false)` - Specifies whether or not to include the
  `AllocatedResources` field in the response.

- `task_states` `(bool: true)` - Specifies whether or not to include the
  `TaskStates` field in the response. TaskStates are included by default but
  can represent a large percentage of the overall response size. Clusters with
  a large number of allocations may set `task_states=false` to significantly
  reduce the size of the response.

- `reverse` `(bool: false)` - Specifies the list of returned allocations should
  be sorted in the reverse order. By default allocations are returned sorted in
  chronological order (older evaluations first), or in lexicographical order by
  their ID if the `prefix` query parameter is used.

#### Field Reference

- `Job` - A copy of the job at the time that the allocation is created or
  updated. This is primarily intended for use by the Nomad client when running
  the allocation, and it may include stale information on some job fields.
  Up-to-date information about the job status is available from the
  [jobs API](/api-docs/jobs); take care to fetch the version of the job
  associated with this allocation.

- `TaskStates` - A map of tasks to their current state and the latest events
  that have effected the state. `TaskState` objects contain the following
  fields:

  - `State`: The task's current state. It can have one of the following
    values:

    - `TaskStatePending` - The task is waiting to be run, either for the first
      time or due to a restart.

    - `TaskStateRunning` - The task is currently running.

    - `TaskStateDead` - The task is dead and will not run again.

  - `StartedAt`: The time the task was last started at. Can be updated through
    restarts.

  - `FinishedAt`: The time the task was finished at.

  - `LastRestart`: The last time the task was restarted.

  - `Restarts`: The number of times the task has restarted.

  - `Events` - An event contains metadata about the event. The latest 10 events
    are stored per task. Each event is timestamped (Unix nanoseconds) and has one
    of the following types:

    - `Setup Failure` - The task could not be started because there was a
      failure setting up the task prior to it running.

    - `Driver Failure` - The task could not be started due to a failure in the
      driver.

    - `Started` - The task was started; either for the first time or due to a
      restart.

    - `Terminated` - The task was started and exited.

    - `Killing` - The task has been sent the kill signal.

    - `Killed` - The task was killed by a user.

    - `Received` - The task has been pulled by the client at the given timestamp.

    - `Failed Validation` - The task was invalid and as such it didn't run.

    - `Restarting` - The task terminated and is being restarted.

    - `Not Restarting` - the task has failed and is not being restarted because
      it has exceeded its restart policy.

    - `Downloading Artifacts` - The task is downloading the artifact(s)
    - specified in the task.

    - `Failed Artifact Download` - Artifact(s) specified in the task failed to
      download.

    - `Restart Signaled` - The task was signaled to be restarted.

    - `Signaling` - The task was is being sent a signal.

    - `Sibling Task Failed` - A task in the same task group failed.

    - `Leader Task Dead` - The group's leader task is dead.

    - `Driver` - A message from the driver.

    - `Task Setup` - Task setup messages.

    - `Building Task Directory` - Task is building its file system.

    Depending on the type the event will have applicable annotations.

## Exec Allocation

This endpoint executes a command inside the isolation container where an allocation is running.
It opens a WebSocket to transmit input to and output from the command.

The table below shows this endpoint's support for
[blocking queries](/api-docs#blocking-queries) and
[required ACLs](/api-docs#acls).

| Blocking Queries | ACL Required                                                                                 |
| ---------------- | -------------------------------------------------------------------------------------------- |
| `NO`             | `namespace:alloc-exec` (and `namespace:alloc-node-exec` if target task uses raw_exec driver) |

### Parameters

- `:alloc_id` `(string: <required>)`- Specifies the UUID of the allocation. This
  must be the full UUID, not the short 8-character one. This is specified as
  part of the path.
- `command` `(string: <required>)` - Specifies the command to be executed. This
  must be a JSON-encoded array of the command to be executed, e.g. `["echo", "hi"]`
  or `["/bin/bash"]`. This is specified as a query parameter.
- `task` `(string: <required>)` - Specifies the task name, as a query parameter.
- `tty` `(bool: false)` - Specifies whether a TTY is allocated for this task, as
  a query parameter.
- `ws_handshake` `(bool: false)` - Specifies whether to expect the authentication
  token in the first frame, as a query parameter.

### Request Frames

Request frames represent the `stdin` stream from the command as well as TTY resize events.
When `?ws_handshake=true`, the first request frame must contain the authentication token.

The following are valid formats:

```
# sending authentication token
{"version":1,"auth_token":"fc3c1968-8d31-5c50-9617-3db2e19ef32e"}

# sending stdin data
{"stdin": {"data": "...base64 encoded string of bytes ..."}}

# indicating stdin is closed
{"stdin": {"close": true}}

# indicating that TTY was resized
{"tty_size": {"height": <characters>, "width": <characters>}}

# basic application-level heartbeat
{}
```

### Response Frames

Response frames represent `stdout` and `stderr` output from the command as well as exit codes:

```
# transferring stdout data
{"stdout": {"data": "...base64 encoded string of bytes ..."}}

# signaling that host closed stdout
{"stdout": {"close": true}}

# transferring stderr data
{"stderr": {"data": "...base64 encoded string of bytes ..."}}

# signaling that host closed stderr
{"stderr": {"close": true}}

# signaling process exited
{"exited": true, "result": {"exit_code": <exit_code_int>}}

# basic application-level heartbeat
{}
```

### Sample Request and Response

Request and response frames encompass the full range of terminal emulator inputs and outputs, including the control characters necessary to render interactive applications. The example response includes instances of the ANSI “control sequence introducer” (CSI), which is ASCII code 27 followed by `[`.

```
# \x12: form feed, to clear terminal
{"stdin":{"data":"DA=="}}

# "\x1b[H\x1b[2J$ ":
# CSI-H (move cursor to top left corner), CSI-2J (clear entire screen), print "$ "
{"stdout":{"data":"G1tIG1sySiQg"}}
```
