import - includes files or references snippets from a Corefile.
The import plugin can be used to include files into the main
configuration. Another use is to reference predefined snippets. Both can help
to avoid some duplication.
This is a unique plugin in that import can appear outside
of a server block. In other words, it can appear at the top of a Corefile
where an address would normally be.
You can use import to include a file or files. This file's location is
relative to the Corefile's location. It is an error if a specific file cannot
be found, but an empty glob pattern is not an error.
You can define snippets to be reused later in your Corefile by defining a block
with a single-token label surrounded by parentheses:
- PATTERN is the file, glob pattern (*) or snippet to include.
Its contents will replace this line, as if that file's contents appeared
here to begin with.
Then you can invoke the snippet with import:
