I have a problem with deploying local virtualbox based swarm - I have followed the instructions in the official docker documentation regarding setting up master/worker nodes using the docker-machine tool. I have created the token on dockerhub and used --swarm (and --swarm-master) with --swarm-discovery token://XXXX ... so far so good, two machines running, seemingly registered as the Swarm master and worker:
spaceback@brutus:~$ docker-machine ls
NAME ACTIVE DRIVER STATE URL SWARM DOCKER ERRORS
swarm-master * (swarm) virtualbox Running tcp://192.168.99.100:2376 swarm-master (master) v1.12.0
swarm-node1 - virtualbox Running tcp://192.168.99.101:2376 swarm-master v1.12.0
spaceback@brutus:~$ docker run --rm swarm list token://[....]
192.168.99.101:2376
192.168.99.100:2376
and after setting the correct environment values using the "eval $(docker-machine env --swarm swarm-master)" I can get status using the "docker info" stating that I have two nodes running... but any attempt to run any other docker swarm commands (docker node..., docker service...) I get "Error response from daemon: 404 page not found".
What am I doing wrong?
It appears you're attempting to use the new swarm mode features against the older docker swarm.
The following script creates a HA Swarm cluster with 3 managers and 2 workers (using Docker 1.12.0):
#=========================
# Creating cluster members
#=========================
docker-machine create --driver virtualbox node1
docker-machine create --driver virtualbox node2
docker-machine create --driver virtualbox node3
docker-machine create --driver virtualbox node4
docker-machine create --driver virtualbox node5
#===============
# Starting swarm
#===============
MANAGER_IP=$(docker-machine ip node1)
docker-machine ssh node1 docker swarm init --advertise-addr $MANAGER_IP
#===============
# Adding members
#===============
MANAGER_TOKEN=$(docker-machine ssh node1 docker swarm join-token --quiet manager)
WORKER_TOKEN=$(docker-machine ssh node1 docker swarm join-token --quiet worker)
docker-machine ssh node2 docker swarm join --token $MANAGER_TOKEN $MANAGER_IP:2377
docker-machine ssh node3 docker swarm join --token $MANAGER_TOKEN $MANAGER_IP:2377
docker-machine ssh node4 docker swarm join --token $WORKER_TOKEN $MANAGER_IP:2377
docker-machine ssh node5 docker swarm join --token $WORKER_TOKEN $MANAGER_IP:2377
List the swarm members
$ docker-machine ssh node1 docker node ls
