When starting a container I receive “configuration file contains legacy configuration keys”.
I have tracked this down to the ‘lxc.logfile’ key. When the container starts it overwrites the lxc.log.file key as lxc.logfile. This is of course a legacy key and thus the warning message.
I have tried using lxc-update-config and manually editing the lxc.conf file to correct the key name. Each time starting the container resets the key to lxc.logfile. I have tried removing the key from lxc.conf. Starting the container creates a new key with the legacy lxc.logfile name.
Host is Ubuntu 16.04 fully patched.
lxc --version 2.21 lxd --version 2.21
/usr/share/lxc/config/common.conf.d contains one file, 00-lxcfs.conf, which contains two lines:
lxc.hook.mount = /usr/share/lxcfs/lxc.mount.hook lxc.hook.post-stop = /usr/share/lxcfs/lxc.reboot.hook
Sequence to re-create the issue. After setting correct keys in lxc.conf
cat /var/log/lxd/x1/lxc.conf lxc.log.file = /var/log/lxd/x1/lxc.log lxc.log.level = warn ...
Then start the container
lxc start x1 cat /var/log/lxd/x1/lxc.conf lxc.logfile = /var/log/lxd/x1/lxc.log lxc.log.level = warn
Thanks very much.
