The key feature of Exoscale DNS resides in its simple JSON API, which allows you to program hosted zones and records.

We assume that you’ve already chosen a zone bundle. If that’s not the case, here’s how to select one.

Authentication is done through the use of the X-DNS-Token. The X-DNS-Token header follows this simple layout: API_KEY:API_SECRET.

In the following examples, should be replaced by your API_KEY:API_SECRET.

Configuring a zone with the API

Create the example.com zone:

curl -H 'X-DNS-Token: <token>' \
     -H 'Accept: application/json' \
     -H 'Content-Type: application/json' \
     -d '{"domain":{"name":"example.com"}}' \
     -X POST \
     https://api.exoscale.com/dns/v1/domains

View the zone:

curl -H 'X-DNS-Token: <token>' \
     -H 'Accept: application/json' \
     https://api.exoscale.com/dns/v1/domains

Configuring a machine record

To configure a record, we need to pass some JSON to our curl request.

We want to create an A record named ‘web’ pointing to the IP 1.2.3.4:

{
  "record":
  {
    "name": "web",
    "record_type": "A",
    "content": "1.2.3.4",
    "ttl": 3600
  }
}

The request will be:

curl  -H 'X-DNS-Token: <token>' \
      -H 'Accept: application/json' \
      -H 'Content-Type: application/json' \
      -X POST \
      -d '{"record":{"name": "web","record_type": "A","content": "1.2.3.4","ttl": 3600}}' \
      https://api.exoscale.com/dns/v1/domains/example.com/records

Configuring a alias record

We want to create a CNAME record named ‘www’ pointing to ‘web.example.com’:

{
  "record":
  {
    "name": "www",
    "record_type": "CNAME",
    "content": "web.example.com",
    "ttl": 3600
  }
}

The request will be:

curl  -H 'X-DNS-Token: <token>' \
      -H 'Accept: application/json' \
      -H 'Content-Type: application/json' \
      -X POST \
      -d '{"record":{"name": "www","record_type": "CNAME","content": "web.example.com","ttl": 3600}}' \
      https://api.exoscale.com/dns/v1/domains/example.com/records

Configuring a Mail Exchange record

We want to create an MX record pointing to ‘mail.example.com’:

{
  "record":
  {
    "name": "",
    "record_type": "MX",
    "content": "mail.example.com",
    "ttl": 3600,
    "prio": 10
  }
}

The request will be:

curl  -H 'X-DNS-Token: <token>' \
      -H 'Accept: application/json' \
      -H 'Content-Type: application/json' \
      -X POST \
      -d '{"record":{"name": "","record_type": "MX","content": "mail.example.com","ttl": 3600,"prio":10}}' \
      https://api.exoscale.com/dns/v1/domains/example.com/records

Configure my domain to point to an IP

We want the domain ‘example.com’ to point to ‘1.2.3.4’:

{
  "record":
  {
    "name": "",
    "record_type": "A",
    "content": "1.2.3.4",
    "ttl": 3600
  }
}

The request will be:

curl  -H 'X-DNS-Token: <token>' \
      -H 'Accept: application/json' \
      -H 'Content-Type: application/json' \
      -X POST \
      -d '{"record":{"name": "","record_type": "A","content": "1.2.3.4","ttl": 3600}}' \
