The docker-compose up command aggregates the output of each container (essentially running docker-compose logs -f ). When the command exits, all containers are stopped. Running docker-compose up -d starts the containers in the background and leaves them running.
.
Likewise, what does Docker compose build do?
Compose is a tool for defining and running multi-container Docker applications. With Compose, you use a YAML file to configure your application's services. Then, with a single command, you create and start all the services from your configuration.
Similarly, does Docker compose build? Build images with Docker Compose The command docker-compose up will only build your image if the image does not exist, but if it exists it will not re-build it every time you start up your application. The command docker-compose up --build will re-build your image if the Dockerfile or image files have changed.
Subsequently, question is, what is the difference between Docker and Docker compose?
They are not only similar, but they also behave like docker counterparts. The only difference is that they affect the entire multi-container architecture defined in the docker-compose. yml configuration file and not just a single container. You'll notice some docker commands are not present in docker-compose.
What is the difference between Kubernetes and Docker?
Docker Swarm. A fundamental difference between Kubernetes and Docker is that Kubernetes is meant to run across a cluster while Docker runs on a single node. Kubernetes is more extensive than Docker Swarm and is meant to coordinate clusters of nodes at scale in production in an efficient manner.

Docker Compose (herein referred to as compose) will use the Dockerfile if you add the build command to your project's docker-compose. yml .
