COREDNS-METADATA(7) CoreDNS Plugins COREDNS-METADATA(7) NAME metadata - enables a metadata collector. DESCRIPTION By enabling metadata any plugin that implements metadata.Provider in- terface <https://godoc.org/github.com/coredns/coredns/plugin/meta- data#Provider> will be called for each DNS query, at the beginning of the process for that query, in order to add its own metadata to con- text. The metadata collected will be available for all plugins, via the Con- text parameter provided in the ServeDNS function. The package (code) documentation has examples on how to inspect and retrieve metadata a plugin might be interested in. The metadata is added by setting a label with a value in the context. These labels should be named plugin/NAME, where NAME is something de- scriptive. The only hard requirement the metadata plugin enforces is that the labels contain a slash. See the documentation for meta- data.SetValueFunc. The value stored is a string. The empty string signals "no metadata". See the documentation for metadata.ValueFunc on how to retrieve this. SYNTAX metadata [ZONES... ] • ZONES zones metadata should be invoked for. PLUGINS metadata.Provider interface needs to be implemented by each plugin willing to provide metadata information for other plugins. It will be called by metadata and gather the information from all plugins in con- text. Note: this method should work quickly, because it is called for every request. EXAMPLES The rewrite plugin uses meta data to rewrite requests.
