We will now look into a few quick examples for how to use attachable networks.
#Docker inspect format go template update
To update a stack which is already inflight, just type in the docker stack deploy command again.įor an example of a stack file checkout my serverless functions project on Github. You can see this by running docker inspect on a service created by a stack file: $ docker inspect webtier_nginx -format="" Stacks consist of regular Swarm Services which have been grouped together by a label. Sxj04xh2z29j webtier_nginx.1 nginx:latest moby Running $ docker stack deploy webtier -compose-file=./docker-compose.yml To use an attachable network with a stack we must define it ahead of time with docker network create then specify the network as external: version: "3" The stack command cannot create a new attachable network. The v3 compose format introduces new options.The stack file is specified through -compose-file.The first argument is the name of the stack i.e.Here's an example of deploying a compose file as a stack: $ docker stack deploy webtier -compose-file=./docker-compose.yml The docker stack deploy command is effectively the equivalent of Docker Compose (a Python app) re-written in Golang. Stacks use the tried-and-tested Docker Compose format to deploy services on a swarm. Once you've created the container docker network inspect core-infra will show a Subnet for the network and other diagnostic information.ĭocker Compose will give an error if you run docker-compose up while in swarm mode, but with the 1.13 release a new feature was added to the Docker core project called stacks. We can also access ports which are not published on the swarm. We were able to access the nginx service by name which is something we couldn't have done from the host.

So let's create an Alpine Linux container with docker run and install curl to test out the nginx instance: docker run -network=core-infra -ti alpine:latest sh

The attachable option is powerful because it means we can use docker run to create a container within the scope of this new network. This is just like would normally create a service on the default ingress network. Now you can create a Swarm service and specify the network: $ docker service create -publish 80:80 -network=core-infra -name nginx nginx That could be a single-node swarm or a larger swarm and is because attachable is a type of overlay network. The scope column shows that the attachable network is only available for Docker hosts in a swarm. An attachable network is type of swarm overlay network: $ docker network create -driver=overlay -attachable core-infra

The Docker CLI has several commands for managing networks such as create, ls, rm and inspect. Create an attachable networkĪn Docker network can be created through the Docker CLI, the API or through a definition in a Docker Compose file. We also show how to use the new docker stack command.

In this post we'll look at the various ways to create an attachable overlay network and what some potential use-cases could be. There were some exciting new features with the release of Docker 1.13.1 including: secret management, stacks, docker-compose v3 and attachable networks.
