How can I debug lxc-create config file?

Question

I use lxc-create -n Test -f t -t busybox to create a lxc-container on Archlinux, just get an error

Error creating container Test

nothing else.

The template lxc-busybox comes from the lxc package from ArchLinux. How do I know what am I doing wrong?

Answer 1

• lxc-update-config -c /path/to/config may help fix configuration problems if a template is not generating current lxc api keywords.
• For a better supported small container option install an Alpine Linux lxc container (which usesbusybox for init)
• Using the pre-built download templates will also give you less problems:

lxc-create -t download -n test

& choose a supported distribution / version / arch:

Distribution: 
alpine
Release: 
3.9
Architecture: 
amd64

Using image from local cache
Unpacking the rootfs

You just created an Alpinelinux 3.9 x86_64 (20190412_13:00) container.
