Cannot resolve host name in Docker Desktop Windows #3810

Closed stefangrossmann closed 2 years ago

stefangrossmann commented 5 years ago

Expected behavior

Assuming, my machine is named workstation-mine.company.network, with IP 10.11.12.13

When calling docker run busybox ping workstation-mine.company.network I would expect that my workstation is reachable from within a docker container.

Actual behavior

The result of the ping is:

ping: bad address 'workstation-mine.company.network'

Information

When I pass the IP of the company-dns it is working:

docker run --dns COMPANY_DNS_IP busybox ping workstation-mine.company.network

PING workstation-mine.company.network (172.25.35.141): 56 data bytes
64 bytes from 172.25.35.141: seq=0 ttl=37 time=1.654 ms
64 bytes from 172.25.35.141: seq=1 ttl=37 time=0.937 ms
64 bytes from 172.25.35.141: seq=2 ttl=37 time=1.333 ms
64 bytes from 172.25.35.141: seq=3 ttl=37 time=1.657 ms

It seems to be not possible to lookup the IP of the own host:

docker run busybox nslookup workstation-mine.company.network
Server:         192.168.65.1
Address:        192.168.65.1:53

** server can't find workstation-mine.company.network: NXDOMAIN

*** Can't find workstation-mine.company.network: No answer

With external hosts and other machines inside our network everything works fine:

docker run busybox ping other-workstation-mine.company.network
PING other-workstation-mine.company.network (10.11.12.14): 56 data bytes
64 bytes from 172.25.35.161: seq=0 ttl=37 time=3.755 ms
64 bytes from 172.25.35.161: seq=1 ttl=37 time=1.752 ms
64 bytes from 172.25.35.161: seq=2 ttl=37 time=1.721 ms
64 bytes from 172.25.35.161: seq=3 ttl=37 time=1.854 ms
64 bytes from 172.25.35.161: seq=4 ttl=37 time=3.148 ms
64 bytes from 172.25.35.161: seq=5 ttl=37 time=1.561 ms
64 bytes from 172.25.35.161: seq=6 ttl=37 time=1.560 ms

The behaviour is the same with if I use 'automatic' DNS-Discovery or if I use a fixed DNS-Server at my docker-settings.

See as well a stackoverflow post from another user which seems to have the same problem: https://stackoverflow.com/questions/55360231/how-to-make-docker-desktop-windows-resolve-the-host-name

Anybody will save us? I am stuck in version 2.0.0.3 because of this issue.

Well, I'm using Docker Desktop 2.3.0.3 and host name resolution is working great. image

I recommend a fresh install. Use/activate WSL2 in your Windows 10 2004 and Docker Desktop.

NathanHealea commented 4 years ago

@mrbrazzi, Could you share some outputs that you used to confirm that host name resolution is working?

I an running in to a similar situation when preforming a nslookup on my domain controller host I receive the following 

C:\inetpub\wwwroot>nslookup *******.**.***.***
Server:  UnKnown
Address:  172.26.208.1

*** UnKnown can't find *******.**.***.***: Server failed

I have attempted setting the deamen.json to contain the IP address of our internal DNS server, however that doesn't seem to work as well.

// deamon.json
...
"dns" : ["**.*.***.**", "8.8.8.8"],
...

I can see though that my internal dns server is listed.

C:\inetpub\wwwroot>ipconfig /all

I am using the following compose file and don't have any issues with inter-container DNS for container "networks".

  1. I am using the suffix .home as aliases.
  2. I am using the alpine (5MB) as DNS. Here is example to run services + "alpine". You can attach to alpine and check with "ping" and "nslookup". 
    
version: '3.7'

services:

basketdata: networks: eshop_net: aliases:

volumes: eshop-basketdata: external: false

networks: eshop_net:

I'm able to resolve name by using

Set-DnsClientServerAddress -InterfaceIndex 5 -ServerAddresses Primary_DNS, Secondary_DNS

But facing Operation Timeout issue. Issue : Here Anybody has an idea about it ?

borisvaningelgom commented 4 years ago

I can confirm this is still an issue for docker desktop version 2.3.0.5. However, I found a fix on this github issue

Create a new network and attach it to the build:

docker network create my-network docker build -t myimage --network=my-network .

This solves the problem for me.

xlf12 commented 4 years ago

Maybe it helps someone ... this worked for me on Win10

docker run --rm -ti ubuntu bash -c 'apt-get update && apt-get install -y iputils-ping && ping host.docker.internal'

When I list my networks, I got a bunch due to having multiple network devices, work VPN and so on:

Using --network flag with "WSL" and "Wi-Fi" work fine, but "nat" does not. Unfortunately, nat is the default so if I forget to pass the flag, I get no internet.

It used to work. Not sure what happened with recent updates.

centran commented 3 years ago

I use Cisco AnyConnect and have had various networking issues. Especially in WSL2. I was having the same issue even when using windows docker containers. This hack/fix worked for docker as it does for WSL2.

Some people have had luck using the AnyConnect client from the windows store. If you can't or don't want to run the windows store app then run this powershell as administrator; after docker engine (or WSL2 terminal) is running. Container doesn't matter as long as docker engine is up and running before running below command.

Get-NetAdapter | Where-Object {$_.InterfaceDescription -Match "Cisco AnyConnect"} | Set-NetIPInterface -InterfaceMetric 6000 ( ^ For Cisco AnyConnect VPN users ^ )

brobichaud commented 3 years ago

I too am facing this issue and have found nothing to mitigate it..

How does this problem still exist after all of this time? This is a huge roadblock in using Docker Desktop in a corporate environment where a VPN is needed to access some resources. It baffles me this has not been fixed by Docker.

jjqq2013 commented 3 years ago

this issue still exists, not only in Windows, but also in Mac. As my investigation, it is caused by the built-in Docker DNS server (named dnssd) which anyway want the IPv6 DNS query result from actual host side DNS resolver. See https://github.com/docker/for-mac/issues/5516

doggy8088 commented 3 years ago

@jjqq2013 In my Windows 10 ver 20H2, I resolved this issue by adding --network "Default Switch" to the docker run command.

I am using docker for windows in my VM, and i don't see default switch or "Wi-Fi" option here. Using nat or TNET doesnt resolve this. Any idea?

doggy8088 commented 3 years ago

@ThirthaS This is not docker related network. It's from Hyper-V's Virtual Switch name. It will not listed in docker network ls, but it works when you run docker run or docker build.

Hi @doggy8088 , I don't see it my Virtual switches as well image

I'm using WindowServer 2019 V 1809. I see the default switch option available in my Windows 10.

doggy8088 commented 3 years ago

@ThirthaS Is it possible that you can remove Hyper-V & Docker completely, reboot, reinstall Hyper-V & Docker, reboot, then try it again?

ThirthaS commented 3 years ago

Hi @doggy8088, I tried setting up a whole new windows server 2019 machine altogether. But it still doesnt have "Default Switch" Only nat gets added after docker installation. So i trying to proceed with Windows 10 machine where default switch is present. But not able to expose any ports with --network as deafult Swicth

Somehow, I find the Docker Desktop 3.5.3 for Windows got better, just a little bit slow, on VPN environment, a ping took 1 second to get response, better than 5 seconds on Mac. Thank you though

LaurentLesle commented 3 years ago

Similar issue we just found after updating to Docker Desktop 4.0.0. Downgrading to 3.5.2 does not cause dns resolution in container. https://github.com/Azure/caf-terraform-landingzones/issues/250

paulburlumi commented 3 years ago

I had a similar issue with Docker Desktop 4.0.0 for Windows. Like others I have found downgrading to 3.5.2 fixes the dns resolution issues in the container.

LaurentLesle commented 3 years ago

Still the same issue with 4.1.0

JeffreyCA commented 3 years ago

The workaround described in https://github.com/moby/moby/issues/38846 worked for me.

Docker Compose

Add a dns block to the service:

services:
  myservice:
    dns:
      - 8.8.8.8

Docker CLI

Add --dns 8.8.8.8 to your docker run command.

ryaneastabrook commented 3 years ago

Add a dns block to the service:

services:
  myservice:
    dns:
      - 8.8.8.8

Unfortunately, adding this DNS entry to our docker-compose.yml makes it impossible to resolve host.docker.internal, which we use for xdebug traffic back to our IDE. It seems we either resolve login.microsoftonline.com or we can debug, but not both.....I'm out of ideas.

Adding this extra_hosts block worked for me (originally a workaround for Docker on Linux):

services:
  myservice:
    dns:
      - 8.8.8.8
    extra_hosts:
      - "host.docker.internal:host-gateway"

CLI equivalent would be to add --add-host host.docker.internal:host-gateway.

Hopefully that works.

I kept that one because it was obviously referring to my local network (DhcpDomain, DhcpServer, IPAddress, etc).

MythicManiac commented 2 years ago

I just ran into this (or a similar) issue, and it seems like DNS resolution fails if there are too many domain parts:

root@4e0c2ea51ed9:/project/app# ping s3.eu-central-1.wasabisys.com
ping: s3.eu-central-1.wasabisys.com: No address associated with hostname
root@4e0c2ea51ed9:/project/app# ping eu-central-1.wasabisys.com
PING eu-central-1.wasabisys.com (130.117.252.18) 56(84) bytes of data.
64 bytes from 130.117.252.18 (130.117.252.18): icmp_seq=1 ttl=37 time=38.4 ms
64 bytes from 130.117.252.18 (130.117.252.18): icmp_seq=2 ttl=37 time=36.5 ms

This used to work on an older docker version, and both domains work when pinged on the host OS.

This eerily reminds me of how CoreDNS does DNS resolution in Kubernetes, in that domains with more than a specific amount of parts are considered internal (can't remember what the default was), as local services are referred to with names such as servicename.namespacename.svc.cluster.local. Unsure if related.

vgusev-arke commented 2 years ago

Hello there,

I keep getting an issue with similar symptoms on fresh Windows installs -- that is, DNS resolution does not work inside Docker containers. Every time I have this problem, the solution below helps me:

  1. In Admin Powershell, run Get-NetIPInterface and write down the ifIndex of your internet adapter (the one that connects you to the outer world),
  2. Run Set-NetIPInterface -InterfaceIndex <ifIndex> -InterfaceMetric 1 to configure your internet adapter to have the highest interface metric.
  3. Restart Docker.

P.S.

I found this solution somewhere on the Internet, but I can't find where exactly anymore.

mauriciogentile commented 2 years ago

I'm using docker compose with custom network assigned to each service:

services: webapp: image: myimage networks: static_network: ports: - 443:443 sql: container_name: ms-sqldb image: mcr.microsoft.com/mssql/server:2017-latest-ubuntu platform: linux/amd64 hostname: sql-server deploy: resources: limits: memory: 4G networks: static_network: ports: - 1433:1433 networks: static_network:

ping command (within the container) doesn't reach the other container.

Restarting/pruning docker doesn't help.

Thanks
