+        Similar to the ``docker build`` command. Either ``path`` or ``fileobj``
+        needs to be set. ``path`` can be a local path (to a directory
+        containing a Dockerfile) or a remote URL. ``fileobj`` must be a
+        readable file-like object to a Dockerfile.
+
+        If you have a tar file for the Docker build context (including a
+        Dockerfile) already, pass a readable file-like object to ``fileobj``
+        and also pass ``custom_context=True``. If the stream is compressed
+        also, set ``encoding`` to the correct value (e.g ``gzip``).
+
+        Example:
+            >>> from io import BytesIO
+            >>> from docker import APIClient
+            >>> dockerfile = '''
+            ... # Shared Volume
+            ... FROM busybox:buildroot-2014.02
+            ... VOLUME /data
+            ... CMD ["/bin/sh"]
+            ... '''
+            >>> f = BytesIO(dockerfile.encode('utf-8'))
+            >>> cli = APIClient(base_url='tcp://127.0.0.1:2375')
+            >>> response = [line for line in cli.build(
+            ...     fileobj=f, rm=True, tag='yourname/volume'

+            extra_hosts (dict): Extra hosts to add to /etc/hosts in building
+                containers, as a mapping of hostname to IP address.
