After execution of this command, the task will switch to `TASK_FINISHED` state. 8 | 9 | To make the finished tasks restart again, we used the `restartStates` array definition within the task object. You can specify the list of task states which should trigger a restart of a task (by default, `TASK_FINISHED` doesn't trigger a restart of the task). 10 | 11 | # dockerSchedulerBridgeNetworking.js 12 | 13 | A simple Docker-based scheduler, which starts a simple Node.js webserver. It uses `BRIDGE` networking to allocate and map container to host ports. 14 | 15 | # dockerSchedulerHostNetworking.js 16 | 17 | A simple Docker-based scheduler, which starts a simple Node.js webserver. It uses `HOST` networking to allocate and use host ports. 18 | 19 | # dockerSchedulerApacheFlink.js 20 | 21 | A more advanced setup, which uses different task type with priorities. This scheduler start a Apache Flink cluster in HA mode (3 jobmanagers and 2 taskmanagers). 22 | 23 | The only two things you should need to change to run this on your cluster are the following: 24 | 25 | * `masterUrl`: Change this either to your leading master's ip address, or use `leader.mesos` in case you're using Mesos DNS. 26 | * `flink_recovery_zookeeper_quorum`: This is the environment variable passed to the Docker containers to enable them to use HA via your existing ZooKeeper cluster (format is `hostIp1:2181,hostIp2:2181,hostIpn:2181`). 27 | -------------------------------------------------------------------------------- /examples/commandScheduler.js: -------------------------------------------------------------------------------- 1 | "use strict"; 2 | 3 | var lib = require("requirefrom")("lib"); 4 | 5 | var Scheduler = lib("scheduler"); 6 | var Builder = lib("builder"); 7 | 8 | var scheduler = new Scheduler({ 9 | "masterUrl": "172.17.11.102", // If Mesos DNS is used this would be "leader.mesos", otherwise use the actual IP address of the leading master 10 | "port": 5050, 11 | "frameworkName": "My first Command framework", 12 | "logging": { 13 | "level": "debug" // Set log Level to debug (default is info) 14 | }, 15 | "restartStates": ["TASK_FAILED", "TASK_KILLED", "TASK_LOST", "TASK_ERROR", "TASK_FINISHED"], // Overwrite the restartStates (by default, TASK_FINISHED tasks are NOT restarted!) 16 | "tasks": { 17 | "sleepProcesses": { 18 | "priority": 1, 19 | "instances": 3, 20 | "commandInfo": new Builder("mesos.CommandInfo").setValue("env && sleep 100").setShell(true), 21 | "resources": { 22 | "cpus": 0.2, 23 | "mem": 128, 24 | "ports": 1, 25 | "disk": 0 26 | } 27 | } 28 | }, 29 | "handlers": { 30 | "HEARTBEAT": function (timestamp) { 31 | this.logger.info("CUSTOM HEARTBEAT!"); 32 | this.lastHeartbeat = timestamp; 33 | } 34 | } 35 | }); 36 | 37 | // Start the main logic once the framework scheduler has received the "SUBSCRIBED" event from the leading Mesos master 38 | scheduler.on("subscribed", function (obj) { 39 | 40 | // Display the Mesos-Stream-Id 41 | scheduler.logger.info("Mesos Stream Id is " + obj.mesosStreamId); 42 | 43 | // Display the framework id 44 | scheduler.logger.info("Framework Id is " + obj.frameworkId); 45 | 46 | // Trigger shutdown after one minute 47 | setTimeout(function() { 48 | // Send "TEARDOWN" request 49 | scheduler.teardown(); 50 | // Shutdown process 51 | process.exit(0); 52 | }, 60000); 53 | 54 | }); 55 | 56 | // Capture "offers" events 57 | scheduler.on("offers", function (offers) { 58 | scheduler.logger.info("Got offers: " + JSON.stringify(offers)); 59 | }); 60 | 61 | // Capture "heartbeat" events 62 | scheduler.on("heartbeat", function (heartbeatTimestamp) { 63 | scheduler.logger.info("Heartbeat on " + heartbeatTimestamp); 64 | }); 65 | 66 | // Capture "error" events 67 | scheduler.on("error", function (error) { 68 | scheduler.logger.error("ERROR: " + (error.message ?
