Draft 20 version of DNS API, with working notes¶

Current API¶

DNS
/dns	POST	Create a new DNS record	{"fqdn":string(name/ip), "value":string(ip/reverse), "type":string(A/PTR)}
/dns/value	DELETE	remove value(ip or reverse) DNS record

Record types¶

Should be implemented in next version of DNS API¶

Path	REST Type	Description	Example Input JSON	Notes
/dns	GET	List of DNS zones managed by the proxy
/dns/zone	GET	List all zone records
/dns/zone/A	GET/PUT/POST/DELETE	A Record - Name to IPv4 address	{"fqdn":string(name), "value":string(ip), "type":string(A)}	Supports multiple records
/dns/zone/PTR	GET/PUT/POST/DELETE	PTR - Reverse record, IP address to Name	{"fqdn":string(ip/ipv6), "value":string(name), "type":string(PTR)}	Does not support multiple records
/dns/zone/CNAME	GET/PUT/POST/DELETE	CNAME - DNS Alias	{"fqdn":string(name), "value":string(name), "type":string(CNAME)}	Bind 9 doesn't support roundrobin cnames, so we should at first limit CNAMEs to a single record
/dns/zone/AAAA	GET/PUT/POST/DELETE	IPv6 A Record - Name to IPv6 address	{"fqdn":string(ipv6), "value":string(name), "type":string(AAAA)}	IPv6 address, supports multiple records
/dns/zone/TXT	GET/PUT/POST/DELETE	TXT - Text string	{"fqdn":string(name), "value":string("arbitrary text string"), "type":string(TXT)}	supports multiple records
/dns/zone/SPF	GET/PUT/POST/DELETE	SPF - Sender Policy Framework records	{"fqdn":string(name), "value":string("v=spf1 a:mail.example.com -all"), "type":string(SPF)}	supports multiple records
/dns/zone/MX	GET/PUT/POST/DELETE	MX - Mail Exchanger records	{"fqdn":string(name), "value":integer(preference), "value":string(ip/name), "type":string(MX)}	Needs an extra preference number field, supports multiple records

Deferred:¶

/dns/zone/SOA (Can not be dynamically deleted, and needs extra code to handle)
/dns/zone/NS (Needs manual serial number increment
/dns/zone/SRV (Needs more research.. Looks easy enough http://en.wikipedia.org/wiki/SRV_record, but isn't a priority yet)
/dns/zone/ZONE (Currently smartproxy uses nsupdate to make changes so zone creation and deletion is not supported on the backend.)

Methods¶

GET - Lists resource records or gets the details of an individual record(s)
PUT - Replaces a record or collection
POST - Creates a new record or records
DELETE - Deletes a record or records

Ohad notes¶

GET /dns/zone/record_type list of all dns records with a given type, for
example all CNAME would be /dns/1.2.3.4/CNAME
GET /dns/zone/record -> details of the specific record.

POST /dns/zone -> creates a new record
DELETE /dns/zone/record -> deletes a record

Additional features¶

An API to retrieve the proxy's settings might be useful for consistency checks and diagnostic reasons.
Should foreman also be provided with the ability to push settings out into the proxies, though this might prove to be a security issue?
