Unable to set IP address using docker labels
wazzaguy opened this issue · comments
I can't seem to set custom ip addresses using labels and through curl -X PATCH
Has dnsdock been abondond ? and if so is there an alternative?
Hi.
I'll try to look to your issues dns others asap.
I also want to update all dependencies of dnsdock and try to keep it up to date more than the last months.
Can you give me a use case a little more detailed so I'll be able to reproduce the issue.
Regards.
I created the dockdns as such:
docker run -d --name dockdns -v /var/run/docker.sock:/var/run/docker.sock -p 192.168.2.60:53:53/udp -p 50080:80 tonistiigi/dnsdock:latest --verbose
I have a test container called: 'wazztest'
I set a label on the container and looked at the output of dnsdock it showed the following:
Added service: a3ad061840ac80f68bcb7f24b01b88df515236cef56c1c59c065e270b8d718a2 {wazztest wjg-alpine 172.17.0.2 -1 []}
docker inspect showed the label was there:
"Config": {
"Labels": {
"com.dnsdock.ip_addr": "192.168.2.60"
}
},
I tried to PATCH directly using curl:
curl http://192.168.2.60:50080/services/abe6b44181aa13b364f4d22743eb00c0d9f94f8be31fe3ba961b92397760a6b5 -X PATCH --data-ascii '{"ip": "192.168.2.60","ttl": 0}'
and I checked if it changed but it hadn't:
curl http://192.168.2.60:50080/services/abe6b44181aa13b364f4d22743eb00c0d9f94f8be31fe3ba961b92397760a6b5
response:
{"Name":"wazztest","Image":"wjg-alpine","Ip":"172.17.0.2","Ttl":0,"Aliases":[]}
I can however change the TTL using curl but I can't using the com.docker.ttl label.
My use case is to supliment my internal dns router which has A records pointing mainly to a reverse proxy with the exception of a couple of docker containers within a swarm.
Everytime I create a new website within the reverse proxy I then have to define an A record on my router to point it to my reverse proxies internal IP.
I'd like to instead define a preferred DNS to DNSDOCK's ip address and have it return the A record host ip I define within a label.

Long time ago, i know, but did you ever get this working? I’m facing exactly the same thing. I want to specify a container and the location of a reverse proxy sever via labels so that I don’t have to manually update my routers dns
