podman-build - Build a container image using a Dockerfile.
podman build [options [...]] [context]
podman build Builds an image using instructions from one or more Dockerfiles and a specified build context directory. The build context directory can be specified as the http or https URL of an archive which will be retrieved and extracted to a temporary location. This command passes the parameters entered in by the user to the buildah bud command https://github.com/projectatomic/buildah/blob/master/docs/buildah-bud.md to do the actual building.

podman build [OPTIONS] NAME[:TAG|@DIGEST]
--build-arg arg=value
Specifies a build argument and its value, which will be interpolated in instructions read from the Dockerfiles in the same way that environment variables are, but which will not be added to environment variable list in the resulting image's configuration.
-f, --file Dockerfile
Specifies a Dockerfile which contains instructions for building the image, either a local file or an http or https URL. If more than one Dockerfile is specified, FROM instructions will only be accepted from the first specified file.
If a build context is not specified, and at least one Dockerfile is a local file, the directory in which it resides will be used as the build context.
--format
Control the format for the built image's manifest and configuration data. Recognized formats include oci (OCI image-spec v1.0, the default) and docker (version 2, using schema format 2 for the manifest).
--pull-always
Pull the image even if a version of the image is already present.
--quiet
Suppress output messages which indicate which instruction is being processed, and of progress when pulling images from a registry, and when writing the output image.
--runtime path
The path to an alternate OCI-compatible runtime, which will be used to run commands specified by the RUN instruction.
--runtime-flag flag
Adds global flags for the container rutime.
--signature-policy signaturepolicy
Pathname of a signature policy file to use. It is not recommended that this option be used, as the default behavior of using the system-wide default policy (frequently /etc/containers/policy.json) is most often preferred.
-t, --tag imageName
Specifies the name which will be assigned to the resulting image if the build process completes successfully.
--tls-verify bool-value
Require HTTPS and verify certificates when talking to container registries (defaults to true)
