将容器的日志记录到 Linux 日志系统
1.将容器的日志记录到 syslog
打开一个终端监控系统日志
[root@host1 ~]# tail -f /var/log/messages
Sep 16 16:15:46 host1 systemd[2615]: Reached target Sockets.
Sep 16 16:15:46 host1 systemd[2615]: Finished Create User's Volatile Files and Directories.
Sep 16 16:15:46 host1 systemd[2615]: Reached target Basic System.
Sep 16 16:15:46 host1 systemd[2615]: Reached target Main User Target.
Sep 16 16:15:46 host1 systemd[2615]: Startup finished in 305ms.打开另一个终端将 Redis 容器的日志记录到 syslog 系统中
[root@host1 ~]# docker run --rm -d --log-driver syslog --name redis redis
06fe4942e07954d229c6305504568d7bd877b8f9840d06d0bfcc47279cd7be46则第一个终端窗口可以看到

Being disabled, it can also cause failures without low memory condition, see https://github.com/jemalloc/jemalloc/issues/1328. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.
