Hi everyone, Please let me why I cannot resolve "localhost" but only 127.0.0.1 I have also added host.docker.internal on my host file in windows 11. Is there any good way to debug this through issue on my environment

why do you need the

host.docker.internal

in the host file on windows? that domain is for inside the wsl vm, can you elaborate on what you are trying to do?

I have added host.docker.internal as docker desktop had this on my host file. I am trying run sql server in container. and bind port 1433 to host so that I can connect from host environment.

calm-sugar-3169

ok, you don’t need to add

host.docker.internal

to windows’s host file. In rancher desktop we already add that entry to the wsl’s host file (inside the vm) and that should be mapped to wsl’s interface IP address. This will allow connectivity from your containers to the host using that domain or even an IP address if one wishes to use IP. What IP address are you using on the host side to bind 1433 to?

I'am having 172.25.80.1 for wsl, and for wireless - 192.168.68.137

calm-sugar-3169

Which IP address are you binding 1433 to?

Can you bind 1433 to

0.0.0.0

and try again?

powerful-electrician-18876

11/18/2022, 8:19 PM

my netstat doesn't show any 1433 port binding and but my docker logs says 127.0.0.1. so I have to change docker yaml to 0.0.0.0?

2022-11-18 150241.56 spid18s Server is listening on [ 'any' <ipv6> 1433]. 2022-11-18 150241.57 spid18s Server is listening on [ 'any' <ipv4> 1433]. 2022-11-18 150241.59 Server Server is listening on [ ::1 <ipv6> 1434]. 2022-11-18 150241.59 Server Server is listening on [ 127.0.0.1 <ipv4> 1434].

thats the docker log

May I ask you how can I bind to 0.0.0.0?

netstat - a gives TCP [:]135 DESKTOP-HEQK2EA:0 LISTENING TCP [:]49668 DESKTOP-HEQK2EA:0 LISTENING TCP [:]49674 DESKTOP-HEQK2EA:0 LISTENING TCP [:1]1433 DESKTOP-HEQK2EA:0 LISTENING TCP [:1]5672 DESKTOP-HEQK2EA:0 LISTENING TCP [:1]6443 DESKTOP-HEQK2EA:0 LISTENING

is it clashing with ipv6 ?

you mentioned earlier that you want to the following:

I am trying run sql server in container. and bind port 1433 to host so that I can connect from host environment.

so you can simply use the publish feature in docker e.g

Copy code

docker run -d -p 1433:[sqlport] sqlImage

this will simply run a sql container and publish the port on the host on 1433, you can then access your database from other containers on

host.docker.internal:1433

in order for this to work you do not need to edit any host file or anything, you would just need to deploy your DB container correctly

powerful-electrician-18876

11/18/2022, 8:32 PM

oh sorry I got confused with host and container. the DB container is created using docker-compose yaml which worked fine in docker desktop.

Copy code

sqlserver:
  image: "<http://mcr.microsoft.com/mssql/server:2017-CU22-ubuntu-16.04|mcr.microsoft.com/mssql/server:2017-CU22-ubuntu-16.04>"
  container_name: sqlserver-integrationtest
  environment:
    SA_PASSWORD: "******"
    ACCEPT_EULA: "Y"
  ports:
    - "1433:1433"

thats the yaml part

calm-sugar-3169

11/18/2022, 8:33 PM

ok, so when you run this what do you see if you do

netstat -ant | findstr '1433'

that’s on the host side windows 11

powerful-electrician-18876

11/18/2022, 8:34 PM

ok thank you

I get TCP 127.0.0.1:1433 0.0.0.0:0 LISTENING InHost

calm-sugar-3169

11/18/2022, 8:35 PM

ok, and hop on the wsl by running

wsl -d rancher-desktop

and then run

netstat -nlp | grep 1433

what do you see in there?

powerful-electrician-18876

11/18/2022, 8:36 PM

I get

tcp 0 0 0.0.0.0:1433 0.0.0.0:* LISTEN 14378/docker-proxy

calm-sugar-3169

11/18/2022, 8:36 PM

can I ask also, what version of Rancher Desktop are you using?

powerful-electrician-18876

11/18/2022, 8:37 PM

1.6.2#

calm-sugar-3169

11/18/2022, 8:38 PM

can you also share with me to output of

netsh interface portproxy show all

on windows

powerful-electrician-18876

11/18/2022, 8:39 PM

no result

calm-sugar-3169

11/18/2022, 8:40 PM

hmm, that’s weird, doesn’t seem right

can you please create an issue and include the steps to reproduce this, I will look into it

powerful-electrician-18876

11/18/2022, 8:41 PM

ok where should I create on git ? sorry its new to me

calm-sugar-3169

11/18/2022, 8:42 PM

no worries, you can create it here: https://github.com/rancher-sandbox/rancher-desktop/issues/new/choose

you can choose, bug report

powerful-electrician-18876

11/18/2022, 8:42 PM

thank you very much I will do that now

calm-sugar-3169

11/18/2022, 8:42 PM

include some steps like

docker-compose.yaml

so I can reproduce it on my end

powerful-electrician-18876

11/18/2022, 8:43 PM

sure

calm-sugar-3169

11/18/2022, 8:43 PM

Thanks 🙂

@powerful-electrician-18876 I just tested this on my end it seems to be work fine 🤔

Copy code

netsh interface portproxy show all

Listen on ipv4:             Connect to ipv4:

Address         Port        Address         Port
--------------- ----------  --------------- ----------
0.0.0.0         1433        172.28.84.230   1433

Listen on ipv6:             Connect to ipv6:

Address         Port        Address         Port
--------------- ----------  --------------- ----------
::              1433        fe80::215:5dff:fe20:4a78 1433

on the windows host side

Copy code

TCP    0.0.0.0:1433           0.0.0.0:0              LISTENING       InHost
  TCP    127.0.0.1:1433         0.0.0.0:0              LISTENING       InHost
  TCP    [::]:1433              [::]:0                 LISTENING       InHost
  TCP    [::1]:1433             [::]:0                 LISTENING       InHost

inside the wsl vm

Copy code

/mnt/c/Users/[redacted] # netstat -nlp | grep 1433
tcp        0      0 0.0.0.0:1433            0.0.0.0:*               LISTEN      21191/docker-proxy
tcp        0      0 :::1433                 :::*                    LISTEN      21199/docker-proxy

this is all correct and seems to be working fine

and I used the docker compose that shared with me

Copy code

version: "3.2"
services:

  sql-server-db:
    image: "<http://mcr.microsoft.com/mssql/server:2017-CU22-ubuntu-16.04|mcr.microsoft.com/mssql/server:2017-CU22-ubuntu-16.04>"
    container_name: sqlserver-integrationtest
    ports:
      - "1433:1433"
    environment:
      SA_PASSWORD: "myPassowrdThingy"
      ACCEPT_EULA: "Y"

I wonder if you need to factory reset your rancher desktop

and remove all the edits that you did on the windows with

host

file

powerful-electrician-18876

11/18/2022, 9:17 PM

ok I will try that now

I get following after factory reset

calm-sugar-3169

11/18/2022, 9:29 PM

that looks like RD isn’t installed correctly

I would strongly recommend uninstall and do a clean install again if you can

powerful-electrician-18876

11/18/2022, 9:30 PM

sure I will do this I taught so as well thanks

Hi Nino I have clean reinstalled. I have same the issue with where I couldn't use localhost. And, "netsh interface portproxy show all" doesn't yield any result. Just a not my work uses "z scaler" and its not a problem with docker desktop. Wonder if it issue with Rancher Desktop

calm-sugar-3169
