Docker Swarm

Seit Version 1.12 bietet Docker eine integrierte Cluster-Implementierung an.

$ docker swarm
$ docker node
$ docker service

# Create a manager (node)
$ docker swarm init --advertise-addr 192.168.99.100

# Generate token needed to join manager
$ docker swarm join-token worker

# Add a worker (node)
$ docker swarm join --token [...] 192.168.99.100:2377

# List nodes
$ docker node ls

# Deploy a service
$ docker service create --replicas 1 --name helloworld alpine ping docker.com
