Docker is a platform that depends on the operating system in applications that are packaged and deployed as containers. By using docker, the applications which designed in a way of microservices architecture deployments became very easy and scalable compared to the monolithic architecture.
Most of the people who are new to docker have confusion what is the difference between docker-compose and docker stack. Let’s look into the difference from each search
Docker-compose is an official tool by docker which can be used to manage and build a docker image and docker containers. This tool doesn’t come with the normal installation of the docker engine. Whereas docker stack is a command embedded in the Docker engine.
Docker-compose and docker stack both support docker-compose.yml and features are picked from the YAML file based on the tool or command which are getting executed.
Docker-compose can manage only a single server where docker-compose is installed. Docker stack invokes docker swarm where it can manage which are joined to docker swarm manager. Docker stack only from the node which has a manager role is assigned.
Below are the commands used to be each one
Docker-compose can build a docker image during the deployment whereas docker stack can manage only docker containers and its deployment. Build features are not available in the docker stack.
As I said before there feature difference between docker stack and docker-compose, for example, depends_on work on docker-compose whereas it won’t support in docker stack. Another example is Placement constraints works with docker stack, it won’t work with docker-compose.
