When using Goland, you can directly use its integrated functions to deploy containers to remote hosts, but what should you do if you directly use the command line? View help:
$ docker-compose --help Usage: docker compose [OPTIONS] COMMAND Docker Compose Options: --ansi string Control when to print ANSI control characters ("never"|"always"|"auto") (default "auto") --compatibility Run compose in backward compatibility mode --env-file string Specify an alternate environment file. -f, --file stringArray Compose configuration files --profile stringArray Specify a profile to enable --project-directory string Specify an alternate working directory (default: the path of the Compose file) -p, --project-name string Project name Commands: build Build or rebuild services convert Converts the compose file to platform's canonical format cp Copy files/folders between a service container and the local filesystem create Creates containers for a service. down Stop and remove containers, networks events Receive real time events from containers. exec Execute a command in a running container. images List images used by the created containers kill Force stop service containers. logs View output from containers ls List running compose projects pause Pause services port Print the public port for a port binding. ps List containers pull pull service images push push service images restart Restart containers rm Removes stopped service containers run Run a one-off command on a service. start Start services stop stop services top Display the running processes unpause Unpause services up Create and start containers version Show the Docker Compose version information Run 'docker compose COMMAND --help' for more information on a command.
There is no option to set the remote host. The last sentence is to run docker compose COMMAND --help
to get more information. I have not installed the docker command under Windows. You can view it under remote Linux:
$ docker compose --help Usage: docker [OPTIONS] COMMAND A self-sufficient runtime for containers Options: --config string Location of client config files (default "/root/.docker") -c, --context string Name of the context to use to connect to the daemon (overrides DOCKER_HOST env var and default context set with "docker context use") -D, --debug Enable debug mode -H, --host list Daemon socket(s) to connect to -l, --log-level string Set the logging level ("debug"|"info"|"warn"|"error"|"fatal") (default "info") --tls Use TLS; implied by --tlsverify --tlscacert string Trust certs signed only by this CA (default "/root/.docker/ca.pem") --tlscert string Path to TLS certificate file (default "/root/.docker/cert.pem") --tlskey string Path to TLS key file (default "/root/.docker/key.pem") --tlsverify Use TLS and verify the remote -v, --version Print version information and quit Management Commands: builder Manage builds config Manage Docker configs container Manage containers context Manage contexts image Manage images manifest Manage Docker image manifests and manifest lists network Manage networks node Manage Swarm nodes plugin Manage plugins secret Manage Docker secrets service management services stack Manage Docker stacks swarm Manage Swarm system Manage Docker trust Manage trust on Docker images volume Manage volumes Commands: attach Attach local standard input, output, and error streams to a running container build Build an image from a Dockerfile commit Create a new image from a container's changes cp Copy files/folders between a container and the local filesystem create Create a new container diff Inspect changes to files or directories on a container's filesystem events Get real time events from the server exec Run a command in a running container export Export a container's filesystem as a tar archive history Show the history of an image images List images import Import the contents from a tarball to create a filesystem image info Display system-wide information inspect Return low-level information on Docker objects kill Kill one or more running containers load Load an image from a tar archive or STDIN login Log in to a Docker registry logout Log out from a Docker registry logs Fetch the logs of a container pause Pause all processes within one or more containers port List port mappings or a specific mapping for the container ps List containers pull Pull an image or a repository from a registry push Push an image or a repository to a registry rename Rename a container restart Restart one or more containers rm Remove one or more containers rmi Remove one or more images run Run a command in a new container save Save one or more images to a tar archive (streamed to STDOUT by default) search Search the Docker Hub for images start Start one or more stopped containers stats Display a live stream of container(s) resource usage statistics stop Stop one or more running containers tag Create a tag TARGET_IMAGE that refers to SOURCE_IMAGE top Display the running processes of a container unpause Unpause all processes within one or more containers update Update configuration of one or more containers version Show the Docker version information wait Block until one or more containers stop, then print their exit codes Run 'docker COMMAND --help' for more information on a command.

You can see the -H, --host list Daemon socket(s) to connect to
option, that’s it.
There are two ways for docker to connect to a remote host:
- Using TCP sockets
The format of TCP socket is:tcp://IP:Port
, such astcp://192.168.1.8:2345
This method requires first opening the container service on the remote host and listening to the specified port, such as2345
podman system service --time=0 tcp:0.0.0.0:2345
If docker needs to modify the docker service file, the ubuntu system I use, the path is:
/lib/systemd/system/docker.service
, add it to the command line of ExecStart
-H tcp://0.0.0.0:2345
See the author’s previous blog posts: Goland uses remote containers for go development and debugging, and Goland connects to https Docker remote services
- Use SSH
The format of SSH is:ssh://account@IP
, such asssh://[email protected]
. When using SSH, you will be asked to enter a password.
1. Arrangement and listing
Order:
docker-compose -H "tcp://192.168.1.8:2345" -f compose.yml -p srv up --remove-orphans -d
Parameter explanation:
-H "tcp://192.168.1.8:2345"
Specifies the method, address and port to connect to the remote host-f compose.yml
specifies the composition file to be used-p srv
specifies the project nameup
put on shelves--remove-orphans
Remove orphans. Remove containers for services that are not defined in the Compose file.-d
Execute the service in the background
The following options are also available for orchestration listings:
--timeout
Set the timeout in seconds when terminating the container. The container first receives SIGTERM and then SIGKILL after the specified timeout.--exit-code-from
Returns the exit code of the selected service container. Stops all containers when containers in the specified service are stopped.--scale
Set the number of containers.--always-recreate-deps
Recreate dependent containers.--renew-anon-volumes
Recreate anonymous volumes instead of retrieving data from the previous container.--no-start
Do not start services after creating them. If this item and--no-deps
are not specified, the specified service and linked services will be started by default.--no-deps
Do not start linked services. If this item and--no-start
are not specified, the specified service and linked services will be started by default.--detach
Run in detached mode. Without this item and--attach-dependecies
, it will not be attached to the dependent container, but will be attached to all started containers.--attach-dependecies
Attach to all started containers and dependencies. Without this item and--detach
, it will not be attached to the dependent container, but will be attached to all started containers.--force-recreate
Recreate all containers even if the container’s configuration and image have not changed. Without this and--no-recreate
, the container will be replaced if the configuration or image changes.--no-recreate
Do not recreate existing containers even if configuration changes. Without this and--force-recreate
, the container will be replaced if the configuration or image changes.--no-build
Do not build the image, and stop if it is missing. Without this item and--build
, an unusable image will be built.--build
Build the image before starting the container. Without this item and--no-build
, an unusable image will be built.--abort-on-container-exit
If any container stops, stop all containers. Without this item, the container is stopped manually.
2. Arrangement for removal
Order:
docker-compose -H "tcp://192.168.1.8:2345" -f compose.yml -p srv down --rmi all --remove-orphans --volumes
Parameter explanation:
-H "tcp://192.168.1.8:2345"
Specifies the method, address and port to connect to the remote host-f compose.yml
specifies the composition file to be used-p srv
specifies the project namedown
Removed--rmi all
Remove all images. To remove only images without custom tags use--rmi local
--remove-orphans
Remove orphans. Remove containers for undefined services in Compose files--volumes
Remove all volumes on termination
Another way to specify the host is to use the environment variable DOCKER_HOST
, for example, set DOCKER_HOST=tcp://192.168.1.8:2345
, and then the host can be arranged without specifying it.
On shelves:
docker-compose -f compose.yml -p srv up --remove-orphans -d
Removal:
docker-compose -f compose.yml -p srv down --rmi all --remove-orphans --volumes
