Spark, Jupyterlab, and other Data Science tooling via Docker Swarm

• Docker
• docker-compose
• Existing Docker registry for storing images
• Existing caching layer for .deb packages

Edit the .env file.

https://docs.docker.com/engine/swarm/swarm-mode/

docker swarm init --advertise-addr=192.168.1.113 --listen-addr=0.0.0.0

Setup across all nodes using provided token and command

Nodes:

• 192.168.1.113 - Asus-Blue (master)
• 192.168.1.145 - Windows WSL2 (worker)
• 192.168.1.105 - Alienware (worker)
• 192.168.1.124 - Laptop (worker)

https://docs.docker.com/engine/swarm/manage-nodes/ Check the status of the swarm cluster

docker node ls

https://docs.docker.com/engine/swarm/stack-deploy/

Use existing Docker image registry

Add the following to your daemon.json Docker file:

"insecure-registries": ["192.168.1.226:5000"]

docker service ls

Download Spark and copy it to sparkmaster, sparkworker, and jupyterlab.

Download livy and copy it to sparkmaster.

Download Spark NLP .jar and copy it to sparkmaster, sparkworker, and jupyterlab.

Build and save the images on the local registry, then deploy:

./build-deploy.sh

Check the status of the stack

docker stack ls
docker stack services spark

Get the full details

docker stack ps spark --no-trunc

Open up the Spark web-ui

http:https://localhost:8090

Open up the Jupyterlab web-ui

http:https://localhost:8888

Look at workers as they execute

http:https://localhost:8081

Look at the submitter

http:https://localhost:4040

Look at Livy

http:https://localhost:8998

Bring everything down

docker stack rm spark
docker swarm leave --force

Download newer upstream versions by running ./build-deploy.sh
