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: docker containers automatically builds at the first time)

docker-compose -f docker-compose.yml --build -d

• Command to stop containers when running 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
