# autopath
|
||
|
|
|
||
|
|
The *autopath* middleware allows CoreDNS to perform server side search path completion.
|
||
|
|
If it sees a query that matches the first element of the configured search path, *autopath* will
|
||
|
|
follow the chain of search path elements and returns the first reply that is not NXDOMAIN.
|
||
|
|
On any failures the original reply is returned.
|
||
|
|
|
||
|
|
Because *autopath* returns a reply for a name that wasn't the original question it will add a CNAME
|
||
|
|
that points from the original name (with the search path element in it) to the name of this answer.
|
||
|
|
|
||
|
|
## Syntax
|
||
|
|
|
||
|
|
~~~
|
||
|
|
autopath [ZONE..] RESOLV-CONF
|
||
|
|
~~~
|
||
|
|
|
||
|
|
* **ZONES** zones *autopath* should be authoritative for.
|
||
|
|
* **RESOLV-CONF** points to a `resolv.conf` like file or uses a special syntax to point to another
|
||
|
|
middleware. For instance `@kubernetes`, will call out to the kubernetes middleware (for each
|
||
|
|
query) to retrieve the search list it should use.
|
||
|
|
|
||
|
|
Currently the following set of middleware has implemented *autopath*:
|
||
|
|
|
||
|
|
* *kubernetes*
|
||
|
|
|
||
|
|
## Examples
|
||
|
|
|
||
|
|
~~~
|
||
|
|
autopath my-resolv.conf
|
||
|
|
~~~
|
||
|
|
|
||
|
|
Use `my-resolv.conf` as the file to get the search path from. This file only needs so have one line:
|
||
|
|
`search domain1 domain2 ...`
|
||
|
|
|
||
|
|
~~~
|
||
|
|
autopath @kubernetes
|
||
|
|
~~~
|
||
|
|
|
||
|
|
Use the search path dynamically retrieved from the kubernetes middleware.
