A manual (interactive CLI) dns-based strategy for greenlock.js for setting, retrieving,
and clearing ACME DNS-01 challenges issued by the ACME server
Prints out a subdomain record for `_acme-challenge` with `keyAuthDigest`
to be tested by the ACME server.
You can then update your DNS manually by whichever method you use and then
press [enter] to continue the process.
```
_acme-challenge.example.com TXT xxxxxxxxxxxxxxxx TTL 60
```
## Install
```bash
npm install --save le-challenge-dns@3.x
```
If you have `greenlock@v2.6` or lower, you'll need the old `le-challenge-dns@3.x` instead.
## Usage
The challenge can be set globally like this:
```js
var leChallengeDns = require('le-challenge-dns').create({
debug: false
});
var Greenlock = require('greenlock');
Greenlock.create({
...
, challenges: {
'dns-01': leChallengeDns
}
, approveDomains: [ 'example.com', '*.example.com' ]
});
```
In can also be set in the `approveDomains` callback instead, like this:
```js
function approveDomains(opts, certs, cb) {
...
opts.subject = 'example.com'
opts.domains = [ 'example.com', '*.example.com' ];
cb(null, { options: opts, certs: certs });
}
```
If you didn't make the dns challenge globally available in the main greenlock config,
you can make it locally available here:
```js
function approveDomains(opts, certs, cb) {
...
if (!opts.challenges) { opts.challenges = {}; }
opts.challenges['dns-01'] = leChallengeDns;
opts.challenges['http-01'] = ...
cb(null, { options: opts, certs: certs });
}
```
NOTE: If you request a certificate with 6 domains listed,
it will require 6 individual challenges.
## Exposed Methods
For ACME Challenge:
* `set(opts, done)`
* `remove(opts, done)`
The options object has whatever options were set in `approveDomains()` as well as the `challenge`:
```js
{ challenge: {
identifier: { type: 'dns', value: 'example.com'
, wildcard: true
, altname: '*.example.com'
, type: 'dns-01'
, token: 'xxxxxx'
, keyAuthorization: 'xxxxxx.abc123'
, dnsHost: '_acme-challenge.example.com'
, dnsAuthorization: 'abc123'
, expires: '1970-01-01T00:00:00Z'
}
}
```
Note: There's no `get()` because it's the DNS server, not the Greenlock server, that answers the requests.
(though I suppose you could implement it if you happen to run your DNS and webserver together... kinda weird though)
For greenlock.js internals:
* `options` stores the internal defaults merged with the user-supplied options
