Nov 08, 2017 · Just a note, Don't set the DNS on the Docker Host to 192.168.1.6. Docker doesn't always work without a DNS server and Docker needs to start up and be able to run the container before the container can resolve DNS. –
If it is a DNS resolver problem, here is the solution: First thing to check is run cat /etc/resolv.conf in the docker container.If it has an invalid DNS server, such as nameserver 127.0.x.x, then the container will not be able to resolve the domain names into ip addresses, so ping google.com will fail.. Second thing to check is run cat /etc/resolv.conf on the host machine.
Nov 17, 2021 · Our Support Engineers have come up with a quick fix to ensure that the docker container runs with a custom DNS server. First, we will track down the address of the DNS server from within Ubuntu with the following command: $ nmcli dev show | grep 'IP4.DNS' IP4.DNS [1]: 10.0.0.2. Then, we will run a docker container with the DNS server obtained ...
04.05.2021 · 3. This answer is not useful. Show activity on this post. So, digging into this issue further (I had the same issue on one of my Pis ), I found that if you're running a local DNS resolver on that server, and you want Docker's DNS to work with it properly, you need to make sure the Pi's /etc/resolv.conf file has the nameserver 127.0.0.1 (as you ...

01.08.2018 · After using dns-gen i was able to access my containers through container.docker . But i realised that i can't ping to www.google.com from my container then i pinged to google's ip and yes getting response. so i stopped dns-gen container and checked and now my containers are resolving domains (able to ping www.google.com).
It's fairly obvious that Google's public DNS servers won't resolve my private DNS requests. I know I can force it with docker --dns 192.168.0.1, or set DOCKER_OPTS="--dns 192.168.0.1" in /etc/default/docker, but my laptop frequently switches networks. It seems like there should be a systematic way of solving this problem.

28.05.2021 · I don't see why this shouldn't work with resolved or dnsmasq DNS resolution (although I use Unbound). You should add the following to each container you run to provide the necessary DNS info. I assume that your DNS resolver is running on the address 172.17.0.1 (correct me if I'm wrong). Using Docker CLI: (just a random example config)
Docker populates /etc/resolv.conf by copying the host's /etc/resolv.conf, and filtering out any local nameservers such as 127.0.1.1.If there are no nameservers left after that, Docker will add Google's public DNS servers (8.8.8.8 and 8.8.4.4). According to the Docker documentation:. Note: If you need access to a host’s localhost resolver, you must modify your DNS service on the host …
Docker: Web works, DNS resolving does not. I'm using pihole in docker. When I run it with --net=host all works good, both web and DNS works. When I run the following code it stops resolving (only removed --net=host and added ports), I can see that no request is reaching it as Total queries count is not rising.
