Local Mantis platform development using docker.


Install Docker on your local machine (if you don't already have it) + Mac + Windows + Linux

Bootstraping the Mantis Cluster in Docker

Download the docker-compose file

Download the docker-compose-local.yml to a local folder mantis

Build a Docker image for Mantis Control Plane (Master)

Clone the Mantis Control Plane:

$ git clone https://github.com/Netflix/mantis-control-plane.git
$ cd mantis-control-plane/
$ ./buildDockerImage.sh

Build Docker image for Mantis Worker

Clone the main Mantis repository:

$ git clone https://github.com/Netflix/mantis.git

# Set an environment variable called MANTIS_INSTALL_DIR to the root of this project
$ export MANTIS_INSTALL_DIR=/Users/user/mantis

Clone the Mantis examples:

$ git clone https://github.com/Netflix/mantis-examples.git
# Create a sine-function artifact
$ cd mantis-examples/
$ ./gradlew clean mantis-examples-sine-function:mantisZipArtifact

# Copy to conf/ that is mounted on the mantis worker Docker image
$ cp sine-function/build/distributions/mantis-examples-sine-function-0.1.0-SNAPSHOT.zip <path to mantis repo>/localdev/conf/

# Build the Worker docker image
$ cd <path to mantis repo>/mantis-server/mantis-server-worker
$ ./buildDockerImage.sh

Build Docker image for Mantis API

Clone the Mantis API project:

$ git clone https://github.com/Netflix/mantis-api.git
$ cd mantis-api/
$ ./buildDockerImage.sh

Start the Mantis cluster

$ cd <path to mantis repo>
$ docker-compose -f docker-compose-new-master.yml up

This starts up the following Docker containers:

  • Zookeeper
  • Mesos Master
  • Mantis Master
  • Mantis API
  • Mesos Slave and Mantis Worker run on a single container (mantisagent)

Create and submit the sine-function Job Cluster via CLI

$ curl -X POST --silent --data @$MANTIS_INSTALL_DIR/localdev/conf/namedJob-template -vvv

$ curl -X POST --silent --data @$MANTIS_INSTALL_DIR/localdev/conf/submitJob-template -vvv

To get a shell on a running container:

$ docker exec -it mantis_mantisagent_1 bash

# Job logs can be found here.
$ cd /tmp/mesos_workdir/slaves/<frameworkid>/frameworks/MantisFramework/executors

Using the Mantis UI

Clone the Mantis UI project:

$ git clone https://github.com/Netflix/mantis-ui.git

Run the following commands (in the root directory of this project) to get all dependencies installed and to start the server:

$ yarn
$ yarn serve

Once the node server is up it should print something like

 App running at:
 Local:   http://localhost:8080/

Point your browser to the above URL and fill out the Registration form as follows

Fresh Mantis UI

  1. Name: Example
  2. Email: example@example.com
  3. Master Name: Example
  4. Mantis API URL: http://localhost:7101
  5. Mesos URL: http://localhost:5050

Click on Create

The Mantis Admin page should have no Job clusters currently.

Create first Cluster

Create a new Job Cluster

Click on the Create New Job Cluster button on the top right.

Specify the cluster name as MySine

Click on Upload file and drag and drop the these two files

  1. mantis-examples/sine-function/build/distributions/mantis-examples-sine-function-0.1.0-SNAPSHOT.zip
  2. mantis-examples/sine-function/build/distributions/mantis-examples-sine-function-0.1.0-SNAPSHOT.json

Create Cluster

Under the section Stage 1 - Scheduling Information click on Edit and reduce the Disk and Network requirements for this worker to 10 and 12 respectively.

Update job resources

Under the section Parameters click on Override Defaults Here you can override values for Job parameters. Let us override the parameter useRandom to true

Override job param

Click Create Job Cluster on the bottom left

Create Job Cluster

This will create the job cluster

Job Cluster created

Now let us submit a new Job for our Job Cluster Click the Submit green button this will open up a submit screen that will allow you to override Resource configurations as well as parameter values.

Submit Job1

Let us skip all that and scroll directly to the bottom and hit the Submit button on the bottom left.

Submit Job

View output of the job

If all goes well your job would go into Launched state.

Job Launched

Scroll to the bottom and in the Job Output section click on Start

You should see output of the Sine function job being streamed below

Running Job

  1. To teardown the Mantis cluster, issue the following command
