docker-compose.yml with "network_mode: host"

[squromiv]

I added "network_mode: host" do docker-compose file. After that

Ok. Deleted section with ports

And rerun docker-compose

So what next?

Can you try to delete that line with disable_ipv6.

I think this only works when using docker networking.

If that is the case I am going to update the documentation.

Of course, I did it. The result is unpromising. Take a look at screenshot, please.

Yup. Looks like port 53 is already in use on your host machine.

Nothing to be done on the project side.

But I will add the above mentioned fix to the documentation!

Perfectly. I`ve found out, that it is used by "systemd-resolved". So we need to free it up.

Finally, in order to use "network_mode: host" in docker-compose file, we need

1. to delete these strings:

ports:
    - 53:53
    - 80:80
    - 3030:3030
    - 10101:10101/udp
 sysctls:
     - net.ipv6.conf.all.disable_ipv6=0

2. to free up port 53, used by another service by default in Ubuntu
