Docker course: getting help
In order to get help with Docker you can use the following commands:
docker --help docker help run docker help ps docker help images docker help rm docker help rmi
If you type in on the command line:
then you will see a list of the command available for Docker. You might need to scroll-up to see the beginning of the output or on Linux and OSX you could run it through less
docker --help 2| less
You can ask for help by typing docker help and then the name of one of the commands so docker help rmi for example and then it gives you some kind of an explanation of what does the rmi command do.
You will find a lot more detailed documentation on the web site of the documentation of Docker. There you can search using the name of the command and find all kinds of documents. For example the reference page if docker rmi.
That's basically how to get help, though you can just search on your favorite search engine
