Host 與 Container 都是 CentOS
啟動 container 加上
-v /etc/localtime:/etc/localtime:ro
Host 與 Container 都是 Debian 為例

2. 啟動 container 時，加上 --net host
$ docker run -d -it \
-v /var/log:/var/log \
--name fail2ban \
--net host \
--privileged \
superitman/fail2ban:latest
Container 缺少的常用套件安裝
CentOS 5.x)
crond, crontab
yum install vixie-cron
service crond start
bzip2
NOTE: 缺少這個，無法解壓 xxx.tar.bz2
yum install bzip2
無法刪除 image ?
刪除 image 出現錯誤
Error response from daemon: No such id: 3076561ea5b708c9f...
Ans:
1. 先找出這個 image 的 container-id
# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
16c3e588af5c 3076561ea5b7 "/bin/bash" 21 minutes ago Exited (0) 13 minutes ago grave_leakey
c03d604fab30 centos:centos5 "/bin/bash" 51 minutes ago Exited (0) 51 minutes ago
2. 刪除 container
# docker rm 16c3e588af5c
3. 再一次刪除 image
# docker rmi 3076561ea5b7
