Instead of watching a single file watch the entire directory and catch the .Name from the event. On any event, just reload the damn thing. This also fixes the problem of loosing events when the inode changes.
file
file enables serving zone data from a RFC-1035 styled file.
The file middleware is used for "old-style" DNS server. It serves from a preloaded file that exists on disk.
Syntax
file dbfile [zones...]
dbfilethe database file to read and parse.zoneszones it should be authoritative for. If empty the zones from the configuration block are used.
If you want to round robin A and AAAA responses look at the loadbalance middleware.
TSIG key configuration is TODO; directive format for transfer will probably be extended with
TSIG key information, something like transfer out [address...] key [name] [base64]
file dbfile [zones... ] {
transfer from [address...]
transfer to [address...]
no_reload
}
transferenables zone transfers. It may be specified multiples times. To or from signals the direction. Addresses must be denoted in CIDR notation (127.0.0.1/32 etc.) or just as plain address. The special wildcard "*" means: the entire internet (only valid for 'transfer to').no_reloadby default CoreDNS will reload a zone from disk whenever it detects a change to the file. This option disables that behavior.
Examples
Load the miek.nl zone from miek.nl.signed and allow transfers to the internet.
file miek.nl.signed miek.nl {
transfer to *
}
