'Deploy a single image or a multicontainer project to a balena application',
help: `\
Usage: \`deploy <appName> ([image] | --build [--source build-dir])\`
Use this command to deploy an image or a complete multicontainer project to an
application, optionally building it first. The source images are searched for
(and optionally built) using the docker daemon in your development machine or
balena device. (See also the \`balena push\` command for the option of building
the image in the balenaCloud build servers.)
Unless an image is specified, this command will look into the current directory
(or the one specified by --source) for a docker-compose.yml file. If one is
found, this command will deploy each service defined in the compose file,
building it first if an image for it doesn't exist. If a compose file isn't
found, the command will look for a Dockerfile[.template] file (or alternative
Dockerfile specified with the \`-f\` option), and if yet that isn't found, it
will try to generate one.
To deploy to an app on which you're a collaborator, use
\`balena deploy <appOwnerUsername>/<appName>\`.
When --build is used, all options supported by \`balena build\` are also supported
by this command.
