# binddns-operator
You can simply manages your DNS records with binddns-operator.
DnsDomain/DnsRule is the CRD of Kubernetes. Users can use them to change DNS records.
## The Example
```
[root@localhost ~]# kubectl get dnsdomain
NAME ENABLED REMARK UPDATE
helloworld.com true 2021-01-21 01:44:05
test.com true 2021-01-20 21:38:09
[root@localhost ~]# kubectl get dnsrule
NAME ZONE ENABLED HOST TYPE DATA TTL MXPRIORITY
helloworld.com-b3378a6c helloworld.com true www A 1.1.1.1 10 0
test.com-8b223ed7 test.com true www A 10.10.10.10 10 0
[root@localhost ~]# nslookup www.test.com 127.0.0.1
Server: 127.0.0.1
Address: 127.0.0.1#53
Name: www.test.com
Address: 10.10.10.10
```
## How To Deploy
We need to deploy Controller and Webhook
### Deploy Controller
```
[root@localhost binddns-operator]# cd deploy/controller/
# Deploy DnsDomain CRD
[root@localhost controller]# kubectl apply -f crd_dnsdomains.yaml
# Deploy DnsRule CRD
[root@localhost controller]# kubectl apply -f crd_dnsrules.yaml
# Deploy RBAC
[root@localhost controller]# kubectl apply -f rbac.yaml
# Deploy ConfigMap
[root@localhost controller]# kubectl apply -f configmap.yaml
# Deploy Controller Deployment
[root@localhost controller]# kubectl apply -f deployment.yaml
```
### Deploy Webhook
```
[root@localhost binddns-operator]# cd deploy/webhook/
# Generate Secret
[root@localhost webhook]# ./webhook-create-signed-cert.sh --service binddns-webhook-svc --secret binddns-webhook-certs --namespace kube-system
# Generate Deployment
[root@localhost webhook]# cat mutatingwebhook.yaml | ./webhook-patch-ca-bundle.sh > mutatingwebhook-ca-bundle.yaml
# Deploy
[root@localhost webhook]# kubectl apply -f mutatingwebhook-ca-bundle.yaml
[root@localhost webhook]# kubectl apply -f service.yaml
[root@localhost webhook]# kubectl apply -f deployment.yaml
```
## Usage
- WebUI: [http://${IP}:5388/console/domains](http://${IP}:5388/console/domains)
- CRD: There is a demo at [deploy/demo/example.yaml](deploy/demo/example.yaml)
## Future
- The better WebUI
- Dynamic rndc key
- Synchronous DnsDomain status
- ...
