The atomic application is meant to be a user-friendly way to install, manage, and run container images using container. Unlike docker commands, it leverages the ability to read and act upon LABELs defined in a Dockerfile. By its nature, it helps authors of Dockerfiles to have their images run as they intended without a significant amount of knowledge by the end users. Atomic has several subcommands:
-
diff
-
host
-
info
-
install
-
images
-
migrate
-
mount
-
push
-
scan
-
stop
-
run
-
top
-
uninstall
-
unmount
-
update
-
version
-
verify
Knowledge of these subcommands can make you a better author of Dockerfiles because you too can simplify end users' interactions with your images. Look to the following sections for more information on these relevant subcommands.
You can display the help file for a container using the atomic command. For example, to display the help file for a container called foobar, you would run the command:
# atomic help foobar
This is the default method of displaying the help file. In this case, the help file is formatted like any typical man page and is displayed (like man) with a pager. The help file needs to be located in the / of the image filesystem and called help.1.
If no help file is present and there is no HELP LABEL defined, atomic will simply tell you it could not find any help associated with that container or image.
