It is an extension of the well-known docker-compose format. So, what’s new in docker compose version 3?įirst, I suggest you take a deeper look at the docker-compose schema. You only need a yaml file in docker-compose format ( version: "3") $ docker deploy -compose-file docker-compose.yml With Docker 1.13, the “new” way to deploy a multi-container composed application is to use docker-compose.yml again ( hurrah!). Deploying multi-container application – the “new” way It’s really too bad, the dab bundle format looks promising, but is useless in Docker 1.12. Currently the dab file format does not support multiple settings from docker-compose.yml and does not support options from the docker service create command. This will create a JSON file that describes a multi-container composed application with Docker images referenced by instead of tags. To create this file, run docker-compose bundle. In order to deploy it to a swarm cluster, you need to create a special deployment specification file (also knows as Distribution Application Bundle) in dab format (see more here). With 1.12 release, that is no longer possible: docker-compose can deploy your application on single Docker host only. Before Docker 1.12, you could use docker-compose to deploy such applications to a swarm cluster. The Docker compose is a tool (and deployment specification format) for defining and running composed multi-container Docker applications. v /var/run/docker.sock:/var/run/docker.sock \ĭeploying multi-container application – the “old” way Printf "\nLocal Swarm Visualizer\n=\n"ĭocker run -it -d -name swarm_visualizer \ SWARM_MASTER=$(docker info -format ":2377

The script initializes docker engine as a swarm master, then starts 3 new docker-in-docker containers and joins them to the swarm cluster as worker nodes. I’ve prepared a shell script to bootstrap a 4 node swarm cluster with Docker registry mirror and the very nice swarm visualizer application.
By running a local Docker registry mirror, you can keep most of the redundant image fetch traffic on your local network and speedup service deployment. When you deploy a new service on a local swarm cluster, I recommend setting up a local Docker registry mirror so you can run all swarm nodes with the -registry-mirror option, pointing to your local Docker registry.

The first option and most widely known is to use a docker-machine tool with some virtual driver (Virtualbox, Parallels or other).īut, in this post, I will use another approach: using docker-in-docker Docker image with Docker for Mac, see more details in my Docker Swarm cluster with docker-in-docker on MacOS post. If you want to run a swarm cluster on a developer’s machine, there are several options. Docker swarm mode implements Raft Consensus Algorithm and does not require using external key value store anymore, such as Consul or etcd.

Read about this exciting feature, create a free Codefresh account, and try building, testing and deploying images instantly.ĭocker Engine 1.12 introduced a new swarm mode for natively managing a cluster of Docker Engines called a swarm. And you can do it without creating a new dab ( Distribution Application Bundle) file, but just using familiar and well-known docker-compose.yml syntax (with some additions) and the -compose-file option.
