Role: coredns

Purpose

Add DNS records for new services to the CoreDNS zone file on coredns_host (coredns_host_ip).

Zone File

/docker_mounts/coredns/<domain>.db

This file is the authoritative zone file for {{ domain }} served by the CoreDNS Docker container on the coredns_host.

Records Managed

Record	Type	Value
`vault.<domain>`	A	`<nginx_proxy_ip>`
`ollama-api.<domain>`	A	`<nginx_proxy_ip>`

All service DNS records point to the NGINX proxy (nginx_proxy_ip), which handles TLS termination and reverse proxying to the actual service backends.

Entry Format

Each DNS record follows this format:

<name>.<domain>.  3600  IN  A  <nginx_proxy_ip>

Example (with defaults domain=example.com, nginx_proxy_ip=192.168.1.30):

vault.example.com.      3600  IN  A  192.168.1.30
ollama-api.example.com. 3600  IN  A  192.168.1.30

Reload

After modifying the zone file, CoreDNS is reloaded by sending SIGHUP to the container:

docker kill --signal=SIGHUP coredns

Idempotency

The role uses Ansible's lineinfile module to add DNS records. This ensures:

Records are added only if they do not already exist
Existing records are not duplicated
Other records in the zone file are not affected
