13-docker 实用技巧

1.在运行容器时命名，命名：--name demo

[root@docker03 opt]# docker run -itd --name demo alpine
c8b1a348241f074e0d6cf66bd6ceda353c042f8d2726f7c5409c8a0c2a610d13
[root@docker03 opt]# docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS                NAMES
c8b1a348241f        alpine              "/bin/sh"           6 seconds ago       Up 5 seconds                             demo

2.容器分配一个主机名，主机名：--hostname demo.com

[root@docker03 opt]# docker run -it --name demo --hostname demo.com alpine
/ # cat /etc/hosts
127.0.0.1	localhost
::1	localhost ip6-localhost ip6-loopback
fe00::0	ip6-localnet
ff00::0	ip6-mcastprefix
ff02::1	ip6-allnodes
ff02::2	ip6-allrouters
172.17.0.5	demo.com demo

3.在退出容器时删除，删除--rm 

[root@docker03 opt]# 
[root@docker03 opt]# docker run -it --rm --name demo --hostname demo.com alpine
/ # exit
[root@docker03 opt]# docker ps -a
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS                    PORTS                NAMES
