I am aware there are a lot of questions about running Docker on windows, however this question is about running the brand new Docker for Windows, on Windows.
In my case I am using Windows 10 Pro 64 bit. According to the site this version should be supported.
I have been following a tutorial I found here:
https://prakhar.me/docker-curriculum/
I also tried following the official guide of course: https://docs.docker.com/docker-for-windows/
In both tutorials I get the same error message when trying to assign a port using either the -P parameter or when trying to specify a port -p 8080:5000:
In the official guide I run docker run -d -p 80:80 --name webserver nginx and get:
C:\Program Files\Docker\Docker\Resources\bin\docker.exe: Error response from daemon: driver failed programming external connectivity on endpoint webserver (f9946544e4c6ad2dd9cb8cbccd251e4d48254e86562bd8e6da75c3bd42c7e45a): Error starting userland proxy: mkdir /port/tcp:0.0.0.0:80:tcp:172.17.0.2:80: input/output error.
Following the unofficial guide i run docker run -p 8888:5000 prakhar1989/catnip and get basically the same error:
C:\Program Files\Docker\Docker\Resources\bin\docker.exe: Error response from daemon: driver failed programming external connectivity on endpoint focused_swartz (48a0c005779c6e89bf525ead2ecff44a7f092495cd22ef7d19973002963cb232): Error starting userland proxy: mkdir /port/tcp:0.0.0.0:8888:tcp:172.17.0.2:5000: input/output error.
If I don't try to assign a port the container will run, but then I don't know how to access it.
The docker version I am running:
Any help would be very appreciated. Thank you.
This is caused by a port numbering conflict: github issue here https://github.com/docker/compose/issues/3277
Essentially the port is in use! The reason resetting worked is because it wiped other mappings off.
