To start the master:

docker run -d --name sparkmaster --net=host -e ROLE=master nicomak/spark:2.0.1

---

To start slaves:

docker run -d --name sparkslave --net=host -e ROLE=slave -e MASTER_URL=spark://[master_host]:7077 nicomak/spark:2.0.1

---

More info

• The --net=host network mode if prefered because Spark opens a lot of random ports.
• Any Spark environment variables can be defined in the container run command through -e options.
