Did you restart docker, and then restart Kubelet? Both restarts are necessary to enable accounting.

Comment 2 Guanghui 2019-12-02 15:14:10 UTC

Yes, I tried both restart docker and atom-openshift-node, but it didn't work.

I found that the system had to be rebooted to take effect.

Comment 3 Ryan Phillips 2019-12-02 15:57:50 UTC

For systemd to detect the new configuration file the following command will pick that up: `systemctl daemon-reexec`.
