Swarm Visualizer is a fancy tool which visualized the Swarm Cluster setup. It displays containers running on each node in the form of visuals. If you are conducting Docker workshop, it's a perfect way to show your audience how the containers are placed under each node. Go..try it out..

Clone the Repository

git clone https://github.com/dockersamples/docker-swarm-visualizer

docker-compose up -d

To run in a docker swarm:

$ docker service create \
  --name=viz \
  --publish=8080:8080/tcp \
  --constraint=node.role==manager \
  --mount=type=bind,src=/var/run/docker.sock,dst=/var/run/docker.sock \
