How to Run

Locally

docker run -it -v /var/run/docker.sock:/var/run/docker.sock -p 4000:4000 jsalonen/swarmist

Against Remote Swarm

Create an SSH tunnel to manager node:

ssh -NL localhost:2375:/var/run/docker.sock user@example.com

Start swarmist and connect to tunneled port:

DOCKER_HOST=http://localhost:2375 npm start

As a Swarm Mode Service

docker service create \
  --name swarmist \
  --constraint node.role==manager \
  --mount type=bind,src=/var/run/docker.sock,dst=/var/run/docker.sock \
  --publish 4000:4000 jsalonen/swarmist

Recipes

Setting up Load Balancing with Traefik

Add Traefik as a service:

docker service create \
	--name traefik \
	--constraint=node.role==manager \
	--publish 80:80 --publish 8080:8080 \
	--mount type=bind,source=/var/run/docker.sock,target=/var/run/docker.sock \
	traefik:v1.1.0-rc2 \
	--docker \
	--docker.swarmmode \
	--docker.domain=local \
	--docker.watch \
	--web
