# Overview of the Docker command line
|
|
|
|
We try to make the Docker command line easy to use, even though you are dealing with a powerful tool and concepts that can be difficult.
|
|
|
|
## Getting help
|
|
|
|
In addition to this online manual, you can always ask for help from the command line itself. `docker help`, `docker --help` or `docker -h`
|
|
will list all the commands available. If you want to get help for a more specific command you can use `--help` or `-h` at any level,
|
|
for example `docker run --help` or `docker context create --help`.
|
|
|
|
## Build, share, run
|
|
|
|
Insert a really small tutorial or links here.
|
|
|
|
## The most important commands
|
|
|
|
- `docker run` will run a new container, from an image you or someone else has built
|
|
- `docker ps` will show the running containers
|
|
- `docker stop` will stop a running container
|
|
- `docker rm` will delete a stopped container NOTE may change this so you can rm a running container, why not?
|
|
- `docker build` builds a new container image from your source code
|
|
- `docker compose` manages a set of containers from a single Yaml configuration file
|
|
|
|
## Deprecated syntax
|
|
|
|
We have made some changes to the syntax of a few commands to make them easier to understand. Where we still support the old
|
|
forms, the command line will tell you the new form, but will still work correctly. In cases where we remove the old
|
|
form you will get help text. If we remove a verb, for example "docker stack" we will display a message saying that the command
|
|
is only available with the Local backend. For example
|
|
|
|
```
|
|
> docker context create my-context --description "some description" --docker "host=tcp://myserver:2376"
|
|
This form of the command is deprecated, please use
|
|
docker context create docker --description "some description" --host=tcp://myserver:2376
|
|
```
