How to reproduce:

  1. Create the stack from this template
  2. Check the records aws route53 list-resource-record-sets --hosted-zone-id %hostedzoneid% and see that there are only A records.
[root@ip-10-5-10-105 ec2-user]# /usr/local/bin/ecssd_agent -sync

ecssd_agent continuously shows adding 1, but nothing happens

Same issue here, creates A record but no SRV...

@javierros Could you take a look at this, please?

I'm having a similar issue. I think it's because I have two VPCs (Production & Test) with private hosted zones for each. Both hosted zones have the same namespace (servicediscovery.internal).

the essd_agent uses ListHostedZonesByNameInput to find the HostedZone to add SRV records and ListHostedZonesByNameInput doesn't seem to return Hosted Zones associated to the VPC from which the ECS Container is running, so it's the agent is trying to add the Production service to the Test Hosted Zone.

https://docs.aws.amazon.com/sdk-for-go/api/service/route53/#ListHostedZonesByNameInput

UPDATE passing a custom domain in ecssd_agent.conf fixed my issue

exec /usr/local/bin/ecssd_agent mydomain.local >> /var/log/ecssd_agent.log 2>&1
