[FIXED] Why didn't Docker create a BRIDGE network when I installed?

Issue

On my computer I have :

NETWORK ID          NAME                DRIVER              SCOPE
661118d67505        Default Switch      ics                 local
eae6a3536ef1        nat                 nat                 local
9d0b1f0209f6        none                null                local

but on the server I just created it installed a bridge network.

I need to create this bridge but don't know what IPs to specify? How can I view the hosts file on the server to see how it is configured?

NEW EDIT

I found that I could run docker network inspect bridge on the other computer to see how it was configured.

That answered one question.

Then, I uninstalled docker and reinstalled. When I ran the docker network ls again I got :

NETWORK ID          NAME                DRIVER              SCOPE
b490355c4a0c        bridge              bridge              local
d64dcade1e83        host                host                local
f7dd78a787db        none                null                local

I now how the bridge network on my computer. But: now, when I run the docker network ls command on my computer, I get this error:

error during connect: Get http://127.0.0.1:2375/v1.40/networks: dial tcp 127.0.0.1:2375: connectex: No connection could be made because the target machine actively refused it

I am forced to use the EXPOST DAEMON under general settings.

Then, I opened my VS2019 project and was told that DOCKER was configured to use LINUX and asked if I wanted to switch to windows. When I said yes, it reconfigured my networks back to what I had originally. I am so confused?

Do I need to run DOCKER with windows config (I imagine I do since I am publishing a .NET API)... if that is the case, what should my networking be? Please help !

Please note: this entire question is to help solve this other question.

Solution

Not sure I fully understand your question , but by default containers connect to the default bridge network: $ docker network ls to see it , usually ifconfig shows it as docker0.
