Latest Update Causes Issues on Docker For Mac about docker-host HOT 8 CLOSED

It's not just mac and it's not just docker-compose.

On Arch Linux with regular docker:

# docker run --rm -i -t --cap-add=NET_RAW --cap-add=NET_ADMIN qoomon/docker-host
[ERROR] docker-host container needs Linux capabilities NET_ADMIN and NET_RAW

and it's not because those capabilities are not set, because they are:

# docker run --rm -i -t --cap-add=NET_RAW --cap-add=NET_ADMIN --entrypoint /bin/sh qoomon/docker-host -c '/usr/sbin/getpcaps $$' 
1: cap_chown,cap_dac_override,cap_fowner,cap_fsetid,cap_kill,cap_setgid,cap_setuid,cap_setpcap,cap_net_bind_service,cap_net_admin,cap_net_raw,cap_sys_chroot,cap_mknod,cap_audit_write,cap_setfcap=eip

from docker-host.

I found the root cause it's because of a new version of getcaps. The output format changed. I will fix it today.

Hmmm all my containers that rely on docker-host suddenly started having issues after this update 👀

from docker-host.

Dockerfile doesn't pin base image - it's simply alpine. Previous build was with alpine 3.12. New one is with 3.13.

@c2h5oh you are right. every commit on master will build a new image with github action and release it a´with the latest tag.

Quick workaround pin your version docker-host:2.5.4

In the mean while I'll pin the base image as well

from docker-host.

latest is based on alpine:3.12 again

from docker-host.

Anyone any ideas what change in alpine version 3.13 causing the problems?

Should be fixed for latest, 2 and 2.5.5
