This file serves as a quick reference for useful Docker commands, helping you manage containers, volumes, and networks efficiently. It covers common tasks like starting and stopping containers, accessing running containers, managing Docker volumes and networks, and more. Whether you're troubleshooting or performing routine tasks, this cheat sheet provides the essential commands to streamline your Docker workflow.
Please feel free to update this README.md if you notice anything that is missing. If you need a different version of Nginx or PHP, kindly fill out the form at this link.
Start and stop the containers
docker-compose up -d --remove-orphans # to start containers
docker-compose down # to down containers
# use -f <file-name>.yml if file name is other than docker-compose.yml, e.g.
docker-compose -f dev-compose.yml up -d Note: The --remove-orphans option in the docker-compose up command is used to remove any containers that are not defined in the current docker-compose.yml file but were part of previous runs of Docker Compose.
Open a terminal inside container
docker-compose exec <service-name> bash
# e.g
docker-compose exec phpfpm bashExecute commands directly into the container without entering it by using:
# to get container ID or image name
docker ps
# then
docker exec -it <container-id-or-image-name> [command]
# e.g.
docker exec -it <container-id-or-image-name> php -v
docker exec -it <container-id-or-image-name> bin/console cache:clean --env=prod# to remove all volumes associated with the current docker-compose.yml
docker-compose down -v
# inspect a specific volume for details
docker volume inspect my-volume
# or to remove a specific volume
docker volume ls
# then copy the Volume Name, e.g., oro-docker_dbdata
docker volume rm oro-docker_dbdata
# get detailed usage information about volumes
docker system df -v
# remove all unused volumes
docker volume prune# list all docker networks
docker network ls
# create a new bridge network
docker network create oro_local
# inspect a specific network for details
docker network inspect oro
# connect a running container to a network (use service name for docker-compose or container ID from docker ps)
docker network connect oro phpfpm
# disconnect a container from a network (use service name for docker-compose or container ID from docker ps)
docker network disconnect oro phpfpm
# remove a network (only if no containers are connected)
docker network rm oro
# remove all unused networks
docker network prune
To view logs for a specific service, use:
# logs for a single service
docker-compose logs <service_name>
# to view the logs of a container in real-time
docker-compose logs -f <service_name>
# logs for all services
docker-compose logs
