Container network is not working
Excuse me, is there anyone you can help me ?
Thanks
I statically compiled lxc And installed to /data/lxc/
Compile and configure
meson setup san_build -Dprefix=/data/lxc --default-library=static \
-Dinit-script=sysvinit \
-Ddbus=false \
-Druntime-path=/data/local/tmp \
-Dstrip=true \
-Dcapabilities=false \
-Dseccomp=false \
-Dselinux=false \
-Dapparmor=false \
-Dlog-path=/data/lxc/var/log/lxc \
-Ddata-path=/data/lxc/lib/lxc \
--localstatedir=/data/lxc/var/ \
-Dc_link_args="-static"
I started lxc-net manually
# /data/lxc/etc/lxc/lx-net start
I am an Android device
