EfficientIP provider based on in-tree provider for ExternalDNS. Supported records:

To run the provider, you must provide the following Environment Variables:

EfficientIP Environment Variables:

Note: The APi authentication requires either EIP_USER/EIP_PASSWORD or EIP_TOKEN/EIP_SECRET.

external-dns-efficientip-webhook Environment Variables:

To run provider in a local environment, you must provide all required settings through environment variables. To run locally, set SERVER_HOST to localhost, otherwise leave it at 0.0.0.0. EfficientIP Provider is a simple web server with several clearly defined routers:

Read data by HTTP GET to /records, see:

curl -H 'Accept: application/external.dns.webhook+json;version=1' localhost:8888/records

If you set DOMAIN_FILTER, DNS will return all records from this domain(s). Because the returned data for a given domain can be large - in some cases tens of thousands of records, it is advisable to use filters to reduce the data to the desired result. Filters are specified via environment variables: DOMAIN_FILTER,EXCLUDE_DOMAIN_FILTER, REGEXP_DOMAIN_FILTER,REGEXP_DOMAIN_FILTER_EXCLUSION,REGEXP_NAME_FILTER.

The following example demonstrates the use of a filter:

# We are looking for all records in these two domains. 
# Unfortunately, they may contain tens of thousands of records.
DOMAIN_FILTER=org.eu.cloud.example.com,org-hq.us.cloud.example.com

# If DOMAIN_FILTER is not enough, you can use regex. Once you use REGEXP_DOMAIN_FILTER, DOMAIN_FILTER will be ignored.
# In following example we restrict zones to *.eu.cloud.example.com or *.org-hq.us.cloud.example.com.
REGEXP_DOMAIN_FILTER=(eu.cloud|org-hq.us).cloud.example.com

# Finally, we filter only those records that have `my-project.org-hq` or `.us.cloud` in the name
REGEXP_NAME_FILTER=(my-project.org-hq|.us.cloud)

Here are the updating rules according to which the data in the DNS server will be updated:

• if updateNew is not part of Update Old , object should be created
• if updateOld is not part of Update New , object should be deleted
• if information is not present (TTL might change) , object should be updated
• if we rename the object, object should be deleted and created

Based on the rules I am providing some examples of data.json creating, changing and deleting records in DNS.

curl -X POST -H 'Accept: application/external.dns.webhook+json;version=1;' -H 'Content-Type: application/external.dns.webhook+json;version=1' -d @data.json localhost:8888/records

Create test.cloud.example.com

{"Create":null,"UpdateOld":null,"UpdateNew":[{"dnsName":"test.cloud.example.com","targets":["1.3.2.1"],"recordType":"A","recordTTL":300}],"Delete":null}

Update test.cloud.example.com (DELETE one record test.cloud.example.com and CREATE two records new-test.cloud.example.com)

{"Create":null,"UpdateOld":[{"dnsName":"test.cloud.example.com","targets":["1.3.2.1"],"recordType":"A","recordTTL":300}],"UpdateNew":[{"dnsName":"new-test.cloud.example.com","targets":["1.2.3.4","4.3.2.1"],"recordType":"A","recordTTL":300}],"Delete":null}

Delete test-new.cloud.example.com

{"Create":null,"UpdateOld":[{"dnsName":"new-test.cloud.example.","targets":["1.2.3.4","4.3.2.1"],"recordType":"A","recordTTL":300}],"UpdateNew":null,"Delete":null}
