+Add a value (e.g. env=*value*) to the built image.  Can be used multiple times.
+If neither `=` nor a `*value*` are specified, but *env* is set in the current

+#### **--os-feature** *feature*
+
+Set the name of a required operating system *feature* for the image which will
+be built.  By default, if the image is not based on *scratch*, the base image's
+required OS feature list is kept, if the base image specified any.  This option
+is typically only meaningful when the image's OS is Windows.

+If *feature* has a trailing `-`, then the *feature* is removed from the set of

+#### **--os-version** *version*
+
+Set the exact required operating system *version* for the image which will be
+built.  By default, if the image is not based on *scratch*, the base image's
+required OS version is kept, if the base image specified one.  This option is
+typically only meaningful when the image's OS is Windows, and is typically set in
+Windows base images, so using this option is usually unnecessary.

+#### **--output**, **-o**=""
+
+Output destination (format: type=local,dest=path)
+
+The --output (or -o) option extends the default behavior of building a container image by allowing users to export the contents of the image as files on the local filesystem, which can be useful for generating local binaries, code generation, etc.
+
+The value for --output is a comma-separated sequence of key=value pairs, defining the output type and options.
+
+Supported _keys_ are:
+- **dest**: Destination path for exported output. Valid value is absolute or relative path, `-` means the standard output.
+- **type**: Defines the type of output to be used. Valid values is documented below.
+
+Valid _type_ values are:
+- **local**: write the resulting build files to a directory on the client-side.
+- **tar**: write the resulting files as a single tarball (.tar).
+
+If no type is specified, the value defaults to **local**.
+Alternatively, instead of a comma-separated sequence, the value of **--output** can be just a destination (in the `**dest** format) (e.g. `--output some-path`, `--output -`) where `--output some-path` is treated as if **type=local** and `--output -` is treated as if **type=tar**.
+
 #### **--pid**=*pid*
 
 Sets the configuration for PID namespaces when handling `RUN` instructions.
