DNSControl has a stand-alone utility that will contact a provider,
|
||
|
|
download the records of one or more zones, and output them to a file
|
||
|
|
in a variety of formats.
|
||
|
|
|
||
|
|
The original purpose of this command is to help convert legacy domains
|
||
|
|
to DNScontrol (bootstrapping). Since bootstrapping can not depend on
|
||
|
|
`dnsconfig.js`, `get-zones` relies on command line parameters and
|
||
|
|
`creds.json` exclusively.
|
||
|
|
|
||
|
|
Syntax:
|
||
|
|
|
||
|
|
dnscontrol get-zones [command options] credkey provider zone [...]
|
||
|
|
|
||
|
|
--creds value Provider credentials JSON file (default: "creds.json")
|
||
|
|
--format value Output format: dsl tsv pretty (default: "pretty")
|
||
|
|
--out value Instead of stdout, write to this file
|
||
|
|
|
||
|
|
ARGUMENTS:
|
||
|
|
credkey: The name used in creds.json (first parameter to NewDnsProvider() in dnsconfig.js)
|
||
|
|
provider: The name of the provider (second parameter to NewDnsProvider() in dnsconfig.js)
|
||
|
|
zone: One or more zones (domains) to download; or "all".
|
||
|
|
|
||
|

# Developer Note
|
||
|
|
|
||
|
|
This command is not implemented for all providers.
|
||
|
|
|
||
|
|
To add this to a provider:
|
||
|
|
|
||
|
|
1. Document the feature
|
||
|
|
|
||
|
|
In the `*Provider.go` file, change the setting to implemented.
|
||
|
|
|
||
|
|
* OLD: ` providers.CanGetZones: providers.Unimplemented(),`
|
||
|
|
* NEW: ` providers.CanGetZones: providers.Can(),`
|
||
|
|
|
||
|
|
2. Update the docs
|
||
|
|
|
||
|
|
```
|
||
|
|
go generate
|
||
|
|
```
|
||
|
|
|
||
|
|
3. Implement the `GetZoneRecords` function
|
||
|
|
|
||
|
|
Find the `GetZoneRecords` function in the `*Provider.go` file.
|
||
|
|
|
||
|
|
If currently returns `fmt.Errorf("not implemented")`.
|
||
|
|
|
||
|
|
Instead, it should gather the records from the provider
|
||
|
|
and return them as a list of RecordConfig structs.
|
||
|
|
|
||
|
|
The code to do that already exists in `GetDomainCorrections`.
|
||
|
|
You should extract it into its own function (`GetZoneRecords`), rather
|
||
|
|
than having it be burried in the middle of `GetDomainCorrections`.
|
||
|
|
`GetDomainCorrections` should call `GetZoneRecords`.
|
||
|
|
|
||
|
|
Once that is done the `get-zone` subcommand should work.
|
||
|
|
|
||
|
|
4. Optionally implemement the `ListZones` function
|
||
|
|
|
||
|
|
If the `ListZones` function is implemented, the command will activate
|
||
|
|
the ability to specify `all` as the zone, at which point all zones
|
||
|
|
will be downloaded.
|
||
|
|
|
||
|
|
(Technically what is happening is by implementing the `ListZones`
|
||
|
|
function, you are completing the `ZoneLister` interface for that
|
||
|
|
provider.)
