This script has been developed to provide a simple-to-use command line interface to the JSON API provided by ClouDNS (http://cloudns.net).
$ git clone https://github.com/tokiwinter/cloudns-api.git
$ sudo cp cloudns-api/bin/cloudns_api.sh /usr/local/bin
$ sudo chmod +x /usr/local/bin/cloudns_api.sh
You should also install jq if you don't have it already.
Usage: cloudns_api.sh [-dfhjs] command [options]
-d run in debug mode (lots of verbose messages)

helper - call a helper function directly
test - perform an authentication test
Environment:
Ensure that the following two environment variables are exported:
CLOUDNS_API_ID - your ClouDNS API ID (auth-id)
CLOUDNS_PASSWORD - your ClouDNS API password (auth-password)
You should ensure that you export the following environment variables correctly. Their existence is tested by the script.
$ export CLOUDNS_API_ID=<your_auth-id>
$ export CLOUDNS_PASSWORD=<your_auth-password>
The script does not currently support sub-auth-id, etc. See Limitations at the end of
this document. This does allow us to operate globally on your account. Ensure you
run this script from a trusted host, unset your envionment variables when done,
remove the assignments from your history (history -d <offset>), and have appropriate
IP restrictions in place on your auth-id (configurable via the ClouDNS web UI).
The -d option will cause cloudns_api.sh to act verbosely and print debug messages as it goes.
The -s option will cause cloudns_api.sh to skip testing authentication prior to each API call.
You can execute an authentication test, to check that your environment is correctly configured, as follows:
$ cloudns_api.sh test
Thu Feb 23 20:33:11 AEDT 2017: Login test successful
List the zones under your account, and their type.
$ cloudns_api.sh listzones
$ cloudns_api.sh listzones
testzone1.com:master
testzone2.com:master
Add a new zone to your account.
$ cloudns_api.sh addzone <zonename>
$ cloudns_api.sh addzone foo.com
Thu Feb 23 19:43:12 AEDT 2017: New zone [foo.com] added
Delete a zone from your account. delzone treats you like an idiot, as deleting an
entire zone is a big deal. You cannot force this operation (with -f). You will be
asked to enter a string, exactly, as well as wait for a 5 second timeout (to give
you time to hit CTRL-C) prior to the zone being removed forever.
$ cloudns_api.sh delzone <zonename>
$ cloudns_api.sh delzone foo.com
Are you sure you want to delete zone [foo.com]?
You must type I-AM-SURE, exactly: I-AM-SURE
Okay. Waiting 5s prior to removal. CTRL-C now if unsure!
Thu Feb 23 19:43:39 AEDT 2017: Zone [foo.com] deleted
Check whether domains are managed under this account.
$ cloudns_api.sh checkzone <zone1> [<zone2> ... <zonen>]
$ cloudns_api.sh checkzone foo.com bar.com
foo.com:present
bar.com:absent
Dump an entire zone in BIND (RFC 1035) format, ideal for redirecting to a file.
$ cloudns_api.sh dumpzone <zonename>
$ cloudns_api.sh dumpzone foo.com
$TTL 3600
@ IN SOA ns1.cloudns.net. support.cloudns.net. 2017022309 7200 1800 1209600 3600
@ 3600 IN NS ns1.cloudns.net.
....
Similar to dumpzone, except it dumps all zones into a particular directory.
This is useful for backing up your entire account. The output directory will be
created if it does not already exist.
$ cloudns_api.sh dumpzone
$ cloudns_api.sh dumpzone /var/backup/zones/
Check whether a zone is updated on all nameservers.
$ cloudns_api.sh zonestatus <zone1> [<zone2> ... <zonen>]
$ cloudns_api.sh zonestatus foo.com bar.com tokitest.com
foo.com:up-to-date
bar.com:not-valid
tokitest.com:out-of-date
View the zone update status per nameserver.
$ cloudns_api.sh nsstatus <zonename>
$ cloudns_api.sh nsstatus tokitest.com
ns1.cloudns.net:true
ns2.cloudns.net:false
ns3.cloudns.net:true
ns4.cloudns.net:true
pns1.cloudns.net:true
pns2.cloudns.net:true
pns3.cloudns.net:true
pns4.cloudns.net:true
List master ips on slave zones. IDs are not shown by default, specify showid=true to
display them.
$ cloudns_api.sh listmaster <zonename> [showid=<true|false>]
$ cloudns_api.sh listmaster example.com showid=true
1.2.3.4 ; id=567890
5.6.7.8 ; id=123456
Add master ip to slave zones.
$ cloudns_api.sh addmaster <zonename> <masterip>
$ cloudns_api.sh addmaster example.com 1.2.3.4
Wed Nov 8 16:50:40 CET 2017: Master IP was added successfully to zone [example.com]
Remove master ip from slave zones. You will be asked to confirm the operation. You
can avoid this, and force the removal, with -f. Obtain the record id using the listmaster
command.
$ cloudns_api.sh delmaster <zonename> <masterid>
$ cloudns_api.sh delmaster example.com id=567890
Are you sure you want to delete master with id [567890]? [y|n]: y
Wed Nov 8 16:51:18 CET 2017: Master successfully deleted
Add a new resource record to a zone.
Options required depend upon the record type being added. The key=value pairs can appear in any order.
For A, AAAA, NS, CNAME, SPF, TXT:
$ cloudns_api.sh addrecord <zonename> type=<type> host=<host> record=<record> ttl=<ttl>
SPF and TXT records are a special case. As their record data could include whitespace and other characters, you should create a single-line file containing the record data. See Examples below.
For MX:
$ cloudns_api.sh addrecord <zonename> type=MX host=<host> record=<record> ttl=<ttl> priority=<priority>
For SRV:
$ cloudns_api.sh addrecord <zonename> type=SRV host=<host> record=<record> ttl=<ttl> priority=<priority> weight=<weight> port=<port>
If you want an apex record, specify host=@.
For non-SPF/TXT records, here a CNAME (some limited validation of values occurs in the script, and then the API does its own validation):
$ cloudns_api.sh addrecord foo.com type=CNAME host=testing record=cnametarget.foo.com. ttl=60
Thu Feb 23 20:01:20 AEDT 2017: Record successfully added with id [24135067]
For SPF/TXT records, add your record data to a file, on a single line, without enclosing quotes.
Reference that in the record=<filename> key=value pair:
$ echo "This isn't text. Oh, it is actually" > /var/tmp/txt.txt
$ cloudns_api.sh addrecord foo.com type=TXT host=testtext record=/var/tmp/txt.txt ttl=60
Thu Feb 23 20:02:51 AEDT 2017: Record successfully added with id [24135071]
$ rm -f /var/tmp/txt.txt
Delete a resource record from a zone by id. You will be asked to confirm the operation. You
can avoid this, and force the removal, with -f. Obtain the record id using the listrecords
command.
$ cloudns_api.sh [-f] delrecord <zonename> id=<id>
$ cloudns_api.sh delrecord foo.com id=24135071
Are you sure you want to delete record with id [24135071]? [y|n]: y
Thu Feb 23 20:05:46 AEDT 2017: Record successfully deleted
Modify an existing resource record. You must specify at least one attribute to modify. You
must know the record id (use the listrecords command to obtain this). The key=value pairs
are the same as with addrecord. You cannot modify a record's type, so don't try that.
If you want to change record for an SPF or TXT record, the same loading-from-file
mechanism as with addrecord applies to modify too.
You can modify as many attributes as you want in a single invocation. If you specify the same attribute twice, the latest specification will be used. The order of attribute specification does not matter.
$ cloudns_api.sh modify <zonename> id=<id> key=<value> [key=<value> ...]
$ cloudns_api.sh modify foo.com id=24135067 ttl=3600 record=newcnametarget.foo.com.
Thu Feb 23 20:11:24 AEDT 2017: Record successfully modified
List records for a specified zone in either BIND (RFC 1035) format or JSON. If you want
apex records, specify host=@. IDs are not shown by default, specify showid=true to
display them, as a BIND-style comment.
$ cloudns_api.sh [-j] listrecords <zonename> [host=<host>] [type=<type>] [showid=<true|false>]
$ cloudns_api.sh listrecords foo.com host=@ type=NS showid=true
@ 3600 IN NS ns1.cloudns.net. ; id=24134077
@ 3600 IN NS ns2.cloudns.net. ; id=24134078
...
Display SOA record details for a specified zone.
$ cloudns_api.sh getsoa <zonename>
$ cloudns_api.sh getsoa foo.com
serialNumber:2017022315
primaryNS:ns1.cloudns.net
adminMail:[email protected]
refresh:7200
retry:1800
expire:1209600
defaultTTL:3600
Modify the SOA record for a specified zone. You can modify one or more parameters in the same invocation. Order does not matter.
$ cloudns_api.sh setsoa <zonename> key=value [key=<value> ...]
Valid keys are:
primary-ns admin-mail refresh retry expire default-ttl
$ cloudns_api.sh setsoa foo.com [email protected] default-ttl=3600
Thu Feb 23 20:20:49 AEDT 2017: default-ttl value same as existing
Thu Feb 23 20:20:49 AEDT 2017: SOA for zone [foo.com] modified
