Unable to open listen socket for address [v1.::1]:631 - Cannot assign requested address

[WMEdelberg]

When trying to run the container build from the image I run into the following error:
Unable to open listen socket for address [v1.::1]:631 - Cannot assign requested address.
I tried to change the port to only being tcp but that did not help - same error.
Any idea? I am running docker on a Windows 10 system.

Thanks a lot in advance.

cups configured to run on bare metal by default and try to bind on localhost:631 instead of all interfaces. Create volume /config and start container again. All configs will be transferred into host fs and you will receive some missing files errors. Stop container, modify this part of /config/etc/cupsd.conf:

# Only listen for connections from the local machine.
# Listen localhost:631
Port 631
Listen /config/state/run/cups/cups.sock

Start container back, only this time bind volume /config/etc and /config/log

Thank you @ilyapavkin , that really helped.

In case anyone else runs into an issue like this outside of cups-docker, like for example setting up a dev container in vscode, here's a snippet of what I did.

RUN cat /etc/cups/cups-pdf.conf \
    | sed 's#Out \${HOME}/PDF#Out /workspaces/<<PROJECT NAME>>/pdf#' \
    > /etc/cups/cups-pdf.conf.new \
    && mv /etc/cups/cups-pdf.conf.new /etc/cups/cups-pdf.conf \
    && cat /etc/cups/cupsd.conf \
    | sed 's#Listen localhost:631#Port 8631#' \
    > /etc/cups/cupsd.conf.new \
    && mv /etc/cups/cupsd.conf.new /etc/cups/cupsd.conf \
    && service cups start \
    && lpadmin -p cups-pdf -v cups-pdf:/ -E -P /usr/share/ppd/cups-pdf/CUPS-PDF_opt.ppd \
    && service cups stop

(This happens to host on 8631)
