external-dns cannot automatically change record type in Google DNS #433
Description
I'm migrating from managing DNS records using CNAMEs
ie.
external-dns.alpha.kubernetes.io/target:
to a more standard setup of using an A record to point at a LoadBalancer.
When I removed the target annotation, I get this error:
time="2018-01-04T16:28:41Z" level=info msg="Del records: test-consul.dev.foo.io. CNAME [helm.dev.foo.io.]"
time="2018-01-04T16:28:41Z" level=info msg="Add records: test-consul.dev.foo.io. CNAME [10.1.1.8]"
time="2018-01-04T16:28:42Z" level=error msg="googleapi: Error 400: Invalid value for 'entity.change.additions[0].rrdata[0]': '10.1.1.8', invalid"
It looks like it's trying to replace the CNAME value with an IP, rather than delete the CNAME record and create a new A record.
Manually removing the old CNAME DNS record allows external-dns to do the right thing.
time="2018-01-04T16:31:44Z" level=info msg="Add records: test-consul.dev.foo.io. A [10.1.1.8]"
time="2018-01-04T16:31:44Z" level=info msg="Add records: helm-dev-test-consul.dev.foo.io. TXT ["heritage=external-dns,external-dns/owner=helm-dev"]"
Any hints on how to avoid a manual migration here?
