[rpi2] ArchARM with VM image: cannot ping 8.8.8.8

[bronze51]

I build an image for Arch ARM (custom-pi-recent.img, what's in a name).
I started lukechilds/dockerpi:vm pi2 with the command below.

I was then able to update the container/img file with pacman.
I can ssh into other devices on my lan.

But when I try to ping 8.8.8.8, there is no output.
I checked journalctl -f, and there is also no information specific to the ping command.

I had understood that the network adapter should be named usb0, but it is named eth0.

I captured the startup log below, but cut out a few lines. Please let me know if should provide more of the startup logs?

I stumbled into this a few hours ago and just noticed that it seems to be "by qemu design", see: #5 (comment)

[matteocarnelos]

I solved by adding the following in the docker-compose.yml file:

...
sysctls:
    - net.ipv4.ping_group_range=0 2147483647
...

For docker run should be the following:

docker run ... --sysctl net.ipv4.ping_group_range="0 2147483647" ...
