Docker compose

Docker compose

Docker-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.

The steps to use docker-compose are

1)create a Dockerfile which defines the image and can be producible everywhere.

2)create a docker-compose yml file to run the services

3)use docker-compose up to start the sevices specified in docker-compose.yml file

Basic commands in docker-compose

  • Command to run docker-containers
docker-compose -f docker-compose.yml up
  • Command to run containers in detached mode
docker-compose -f docker-compose.yml up -d
  • command to run containers after building the images again (note: first time we run docker containers build will happen automatically)
docker-compose -f docker-compose.yml --build -d
  • Command to stop containers when we run in detached mode
docker-compose -f docker-compose.yml down
  • Command to remove service containers
docker-compose -f docker-compose.yml rm
  • Command to pull Images for all service containers from repository (by default from Docker Hub)
docker-compose -f docker-compose.yml pull
  • Command to view logs of all service contaienrs (add -f to follow logs)
docker-compose -f docker-compose.yml logs
