+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**.
