Networking

Command Description
docker network ls List all existing Docker networks. Displays details such as network name, ID, driver type, and scope.
docker network create <network-name> Create a new user-defined network with the specified name. By default, it uses the bridge driver.
docker network create --driver <driver-name> <network-name> Create a network using a specific driver (e.g., bridge, overlay, host, or none).
docker network rm <network-name> Remove a Docker network. The network must not be in use by any containers.
docker network inspect <network-name> Display detailed information about a network, including connected containers, IP ranges, and driver type.
docker run --network <network-name> <image> Start a container and connect it to a specific network at runtime.
docker network connect <network-name> <container-id> Connect an existing container to a specified network.
docker network disconnect <network-name> <container-id> Disconnect a container from a specific network.
docker network prune Remove all unused Docker networks. Be cautious as it deletes networks not being used by containers.
docker-compose up Automatically creates and manages a network for the services defined in the docker-compose.yml file.
docker network create --subnet=<CIDR> <network-name> Create a network with a custom subnet (CIDR notation).
docker network create --gateway=<IP> <network-name> Create a network with a custom gateway IP address.
docker network create -o com.docker.network.bridge.name=<bridge-name> <network-name> Create a bridge network with a specific bridge name.

Command Description
docker volume ls List all volumes
docker volume create <volume-name> Create a new volume
docker volume rm <volume-name> Remove a volume
docker run -v <volume-name>:<container-path> <image> Mount a volume into a container
docker volume create --driver local --opt type=nfs --opt o=addr=<NFS_SERVER_IP>,rw --opt device=:/export/shared my-nfs-volume Create centrlized nfs sharing volume

Docker Compose

Command Description
docker-compose up Start all services defined in a docker-compose.yml file. Creates and starts containers as needed.
docker-compose up -d Start services in detached mode (running in the background).
docker-compose down Stop and remove containers, networks, volumes, and images created by docker-compose up.
docker-compose down -v Stop and remove services along with their associated volumes.
docker-compose ps List the status of containers for the services defined in the docker-compose.yml file.
docker-compose logs View logs for all running services. By default, it displays real-time logs.
docker-compose logs -f Follow logs in real-time for services defined in the docker-compose.yml file.
docker-compose build Build or rebuild images for services defined in the docker-compose.yml file.
docker-compose build --no-cache Build services without using the cache. Forces a fresh build.
docker-compose pull Pull the latest images for all services defined in the docker-compose.yml file.
docker-compose start Start containers for services that were stopped but not removed.
docker-compose stop Stop running containers without removing them. They can be restarted later using docker-compose start.
docker-compose restart Restart running containers for services defined in the docker-compose.yml file.
