ORIGINAL REQUEST
I think it's not a real issue so I am asking for help.
I have a vps used only for openVPN. I have done all installation steps and required sucessufully except the error that I got on make deploy: 0.0.0.0:53: bind: address already in use.

I dont think openvpn needs that, how I can fix it?

/etc/systemd/resolved.conf
[Resolve] DNS=8.8.8.8 8.8.4.4 Domains=com

I fixed removing the docker in error:
docker rm "6b89568fb6ad8fb5d83c8d0814600d58cac31e4878a71e81e6a18b70553de70a"

ORIGINAL REQUEST
Here again as you can see I fixed the previous issue with "bind: address already in use."
lsof -i :53 now show an empty result.

I need to performe the last step 16/16.
When I execute "make deploy" I get the following error message:
Step 16/16 : CMD ["sh", "-c", "/root/setup.sh ; service bind9 start ; /root/dyndns"] ---> Using cache ---> a6aab2b09f7c Successfully built a6aab2b09f7c Successfully tagged davd/docker-ddns:latest docker run -it -d -p 8080:8080 -p 53:53 -p 53:53/udp --env-file envfile --name=dyndns davd/docker-ddns:latest docker: Error response from daemon: Conflict. The container name "/dyndns" is already in use by container "6b89568fb6ad8fb5d83c8d0814600d58cac31e4878a71e81e6a18b70553de70a". You have to remove (or rename) that container to be able to reuse that name. See 'docker run --help'. make: *** [Makefile:40: deploy] Error 125
Any suggest?

Now I will try next step...the issue about port 53 in use fixed and also the final "make deploy".
