Operator HTTP API
Mesos 1.0.0 added experimental support for v1 Operator HTTP API.
Overview
Both masters and agents provide the /api/v1
endpoint as the base URL for performing operator-related operations.
Similar to the Scheduler and Executor HTTP APIs, the operator endpoints only accept HTTP POST requests. The request body should be encoded in JSON (Content-Type: application/json) or Protobuf (Content-Type: application/x-protobuf).
For requests that Mesos can answer synchronously and immediately, an HTTP response will be sent with status 200 OK, possibly including a response body encoded in JSON or Protobuf. The encoding depends on the Accept header present in the request (the default encoding is JSON). Responses will be gzip compressed if the Accept-Encoding header is set to "gzip".
For requests that require asynchronous processing (e.g., RESERVE_RESOURCES
), an HTTP response will be sent with status 202 Accepted. For requests that result in a stream of events (SUBSCRIBE
), a streaming HTTP response with RecordIO encoding is sent. Currently, gzip compression is not supported for streaming responses.
Master API
This API contains all the calls accepted by the master. The canonical source of this information is master.proto (NOTE: The protobuf definitions are subject to change before the beta API is finalized). These calls are typically made by human operators, tooling or services (e.g., Mesos WebUI). While schedulers can make these calls as well, schedulers are expected to use the Scheduler HTTP API.
Calls To Master And Responses
Below are the example calls to master that result in synchronous responses from the API.
GET_HEALTH
This call retrieves the health status of master.

GET_LOGGING_LEVEL
This call retrieves the master's logging level.

SET_LOGGING_LEVEL
Sets the logging verbosity level for a specified duration for master. Mesos uses glog for logging. The library only uses verbose logging which means nothing will be output unless the verbosity level is set (by default it's 0, libprocess uses levels 1, 2, and 3).

Events
Currently, the only call that results in a streaming response is the SUBSCRIBE
call sent to the master API.
SUBSCRIBE Request (JSON):
POST /api/v1 HTTP/1.1
Host: agenthost:5051
Content-Type: application/json
Accept: application/json
{
"type": "SUBSCRIBE"
}
SUBSCRIBE Response Event (JSON):
HTTP/1.1 200 OK
Content-Type: application/json
Transfer-Encoding: chunked
<event-length>
{
"type": "SUBSCRIBED",
"subscribed" : {
"get_state" : {...}
}
}
<more events>
The client is expected to keep a persistent connection open to the endpoint even after getting a SUBSCRIBED
HTTP Response event. This is indicated by "Connection: keep-alive" and "Transfer-Encoding: chunked" headers with no "Content-Length" header set. All subsequent events generated by Mesos are streamed on this connection. The master encodes each Event in RecordIO format, i.e., string representation of length of the event in bytes followed by JSON or binary Protobuf encoded event.
The following events are currently sent by the master. The canonical source of this information is at master.proto. Note that when sending JSON encoded events, master encodes raw bytes in Base64 and strings in UTF-8.
SUBSCRIBED
The first event sent by the master when a client sends a SUBSCRIBE
request on the persistent connection. This includes a snapshot of the cluster state. See SUBSCRIBE
above for details. Subsequent changes to the cluster state can result in more events (currently only TASK_ADDED
and TASK_UPDATED
are supported).
TASK_ADDED
Sent whenever a task has been added to the master. This can happen either when a new task launch is processed by the master or when an agent re-registers with a failed over master.
TASK_ADDED Event (JSON)
<event-length>
{
"type": "TASK_ADDED",

},
"command": {
"value": "sleep",
"arguments": [
"100"
]
}
}
}
}
TASK_UPDATED
Sent whenever the state of the task changes in the master. This can happen when a status update is received or generated by the master. Since status updates are retried by the agent, not all status updates received by the master result in the event being sent.
TASK_UPDATED Event (JSON)
<event-length>
{
"type": "TASK_UPDATED",

Agent API
This API contains all the calls accepted by the agent. The canonical source of this information is agent.proto (NOTE: The protobuf definitions are subject to change before the beta API is finalized). These calls are typically made by human operators, tooling or services (e.g., Mesos WebUI). While executors can make these calls as well, it is expected for those to use the Executor HTTP API.
Calls To Agent And Responses
Below are the example calls to agent that result in synchronous responses from the API.

Request and Response are similar to GET_HEALTH call to master.
