:title: Build Command :description: Build a new image from the Dockerfile passed via stdin :keywords: build, docker, container, documentation ================================================ ``build`` -- Build a container from a Dockerfile ================================================ :: Usage: docker build [OPTIONS] PATH | - Build a new container image from the source code at PATH -t="": Tag to be applied to the resulting image in case of success. Examples -------- .. code-block:: bash docker build . | This will read the Dockerfile from the current directory. It will also send any other files and directories found in the current directory to the docker daemon. | The contents of this directory would be used by ADD commands found within the Dockerfile. | This will send a lot of data to the docker daemon if the current directory contains a lot of data. | .. code-block:: bash docker build - | This will read a Dockerfile from Stdin without context. Due to the lack of a context, no contents of any local directory will be sent to the docker daemon. | ADD doesn't work when running in this mode due to the absence of the context, thus having no source files to copy to the container.
