I'm using docker 1.12.1
I have an easy docker-compose script.
version: '2'
services:
jenkins-slave:
build: ./slave
image: jenkins-slave:1.0
restart: always
ports:
- "22"
environment:
- "constraint:NODE==master1"
jenkins-master:
image: jenkins:2.7.1
container_name: jenkins-master
restart: always
ports:
- "8080:8080"
- "50000"
environment:
- "constraint:NODE==node1"
I run this script with docker-compose -p jenkins up -d.
This Creates my 2 containers but only on my master (from where I execute my command). I would expect that one would be created on the master and one on the node.
I also tried to add
networks:
jenkins_swarm:
driver: overlay
and
networks:
- jenkins_swarm
After every service but this is failing with:
Cannot create container for service jenkins-master: network jenkins_jenkins_swarm not found
While the network is created when I perform docker network ls
Someone who can help me to deploy 2 containers on my 2 nodes with docker-compose. Swarm is defenitly working on my "cluster". I followed this tutorial to verify.
Elton Stoneman :
Compose doesn't support Swarm Mode at the moment. \n\nWhen you run docker compose up on the master node, Compose issues docker run commands for the services in the Compose file, rather than docker service create - which is why the containers all run on the master. See this answer for options.\n\nOn the second point, networks are scoped in 1.12. If you inspect your network you'll find it's been created at swarm-level, but Compose is running engine-level containers which can't see the swarm network.",
