File=Containerfile

--file, -f=Containerfile
<< endif >>
Specifies a Containerfile which contains instructions for building the image, either a local file or an http or https URL. If more than one Containerfile is specified, FROM instructions are only be accepted from the last specified file.
<< if is_quadlet >>
Note that for a given relative path to a Containerfile, or when using a http(s):// URL, you also must set
SetWorkingDirectory= in order for podman build to find a valid context directory for the
resources specified in the Containerfile.
Note that setting a File= field is mandatory for a .build file, unless SetWorkingDirectory (or
a WorkingDirectory in the Service group) has also been set.
<< else >>
If a build context is not specified, and at least one Containerfile is a
local file, the directory in which it resides is used as the build
context.
<< endif >>
Specifying the option << 'File=-' if is_quadlet else '-f -' >> causes
the Containerfile contents to be read from stdin.
