Specifying docker-compose.yml
We already defined the docker-compose.yml file in the previous chapters and it looked similar to the following one:
version: "3"services: calculator: deploy: replicas: 3 image: leszko/calculator:latest ports: - "8881:8080" redis: deploy: replicas: 1 image: redis:latest
Note that all images must be pushed to the registry before running the docker stack command so that they would be accessible from all nodes. It is therefore not possible to build images inside docker-compose.yml.
With the presented docker-compose.yml configuration, we will run three calculator containers and one redis container. The endpoint of the calculator service will be exposed on port 8881.
