* Rename middleware to plugin first pass; mostly used 'sed', few spots where I manually changed text. This still builds a coredns binary. * fmt error * Rename AddMiddleware to AddPlugin * Readd AddMiddleware to remain backwards compat |

autopath
The autopath plugin 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.conflike file or uses a special syntax to point to another plugin. For instance@kubernetes, will call out to the kubernetes plugin (for each query) to retrieve the search list it should use.
Currently the following set of plugin has implemented autopath:
- kubernetes
- erratic
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 plugin.
Bugs
When the cache plugin is enabled it is possible for pods in different namespaces to get the same answer.
