Docker的容器管理
一、容器的创建
1.运行一个挂掉的容器
docker run centos
# 这个写法会产生多条独立的容器记录。且因为容器内没有程序在运行，所以挂了。
[root@node1 ~]# docker run centos
[root@node1 ~]# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
d01b358d1736 centos "/bin/bash" 4 seconds ago Exited (0) 3 seconds ago gallant_williamson
2db168499262 redis "docker-entrypoint.s…" 24 hours ago Up 24 hours 6379/tcp, 0.0.0.0:8021->8021/tcp, :::8021->8021/tcp cool_ganguly

964648a939b9 nginx "/docker-entrypoint.…" 26 hours ago Created
2.开启容器运行某个程序
运行容器，且进入容器空间内，运行某个命令
[root@node1 ~]# docker run centos:7.8.2003 ping baidu.com
PING baidu.com (220.181.38.148) 56(84) bytes of data.

3.运行一个存活的容器
-d 让容器存活运行，针对宿主机而言
--rm 容器挂掉后自动删除
--name 命令容器名称
[root@node1 ~]# docker run -d centos:7.8.2003 ping baidu.com
91abb153df28322c9dcb1dc4a398f21341ca5613c8ecf8b86e996a142e4eaf74
[root@node1 ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
91abb153df28 centos:7.8.2003 "ping baidu.com" 5 seconds ago Up 5 seconds suspicious_hoover
2db168499262 redis "docker-entrypoint.s…" 24 hours ago Up 24 hours 6379/tcp, 0.0.0.0:8021->8021/tcp, :::8021->8021/tcp cool_ganguly
2716e3ec1417 nginx "/docker-entrypoint.…" 26 hours ago Up 25 hours 0.0.0.0:80->80/tcp, :::80->80/tcp
4.自定义容器名称
root@node1 ~]# docker run -d --rm --name test-ping centos:7.8.2003 ping baidu.com
cac482a9861efdef656de62b7906d2aa41444c7fc969c44e3f9a2311a6e8b624

二、查看容器的日志
1.实时监控某个容器日志
[root@node1 ~]# docker logs -f 2716e3ec1417

2.过滤某个容器日志
[root@node1 ~]# docker logs 91abb153df28 |tail -5
64 bytes from 39.156.69.79 (39.156.69.79): icmp_seq=780 ttl=127 time=30.1 ms

64 bytes from 39.156.69.79 (39.156.69.79): icmp_seq=784 ttl=127 time=30.1 ms
三、进入正在运行的容器空间
[root@node1 ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
91abb153df28 centos:7.8.2003 "ping baidu.com" 16 minutes ago Up 16 minutes suspicious_hoover

2716e3ec1417 nginx "/docker-entrypoint.…" 26 hours ago Up 26 hours 0.0.0.0:80->80/tcp, :::80->80/tcp naughty_driscoll
[root@node1 ~]# docker exec -it 91abb153df28 bash

四、查看容器的信息

五、容器的端口映射
1.进入容器内查看服务文件
[root@node1 ~]# docker run -it nginx sh
# cat /etc/red ^H^H^H^C
# cat /etc/os-release
PRETTY_NAME="Debian GNU/Linux 10 (buster)"
NAME="Debian GNU/Linux"
VERSION_ID="10"
VERSION="10 (buster)"
VERSION_CODENAME=buster
ID=debian
HOME_URL="https://www.debian.org/"
SUPPORT_URL="https://www.debian.org/support"
BUG_REPORT_URL="https://bugs.debian.org/"
# pwd
/
# ls
bin boot dev docker-entrypoint.d docker-entrypoint.sh etc home lib lib64 media mnt opt proc root run sbin srv sys tmp usr var
# cat docker-entrypoint.sh
#!/bin/sh
# vim:sw=4:ts=4:et
set -e
if [ -z "${NGINX_ENTRYPOINT_QUIET_LOGS:-}" ]; then
exec 3>&1
else
exec 3>/dev/null
fi
if [ "$1" = "nginx" -o "$1" = "nginx-debug" ]; then
if /usr/bin/find "/docker-entrypoint.d/" -mindepth 1 -maxdepth 1 -type f -print -quit 2>/dev/null | read v; then
echo >&3 "$0: /docker-entrypoint.d/ is not empty, will attempt to perform configuration"
echo >&3 "$0: Looking for shell scripts in /docker-entrypoint.d/"
find "/docker-entrypoint.d/" -follow -type f -print | sort -V | while read -r f; do
case "$f" in
*.sh)
if [ -x "$f" ]; then
echo >&3 "$0: Launching $f";
"$f"
else
# warn on shell scripts without exec bit
echo >&3 "$0: Ignoring $f, not executable";
fi
;;
*) echo >&3 "$0: Ignoring $f";;
esac
done
echo >&3 "$0: Configuration complete; ready for start up"
else
echo >&3 "$0: No files found in /docker-entrypoint.d/, skipping configuration"
fi
fi
exec "$@"
2.进行容器端口映射
后台运行nginx容器，并且命名容器空间，且端口映射宿主主机的85端口，访问容器的80端口
[root@node1 ~]# docker run -d -p 85:80 --name web nginx
eee0a7682471663bc13de8ad4474cf63babd8a18b1b4d695392ae33d9de6ce76
[root@node1 ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
eee0a7682471 nginx "/docker-entrypoint.…" 4 seconds ago Up 3 seconds 0.0.0.0:85->80/tcp, :::85->80/tcp web
91abb153df28 centos:7.8.2003 "ping baidu.com" 31 minutes ago Up 31 minutes suspicious_hoover
2db168499262 redis "docker-entrypoint.s…" 25 hours ago Up 25 hours 6379/tcp, 0.0.0.0:8021->8021/tcp, :::8021->8021/tcp cool_ganguly
[root@node1 ~]#
3.查看容器的端口转发情况
[root@node1 ~]# docker port web
80/tcp -> 0.0.0.0:85
80/tcp -> :::85
4.测试web页面
5.随机端口映射
[root@node1 ~]# docker run -d -P --name web001 nginx
ac598bc79e84e3ec9da061d62b084992b1dc4d95137601a16887c761c128c3f2
[root@node1 ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
ac598bc79e84 nginx "/docker-entrypoint.…" 8 seconds ago Up 7 seconds 0.0.0.0:49153->80/tcp, :::49153->80/tcp web001
eee0a7682471 nginx "/docker-entrypoint.…" 5 minutes ago Up 5 minutes 0.0.0.0:85->80/tcp, :::85->80/tcp web
91abb153df28 centos:7.8.2003 "ping baidu.com" 37 minutes ago Up 37 minutes suspicious_hoover
2db168499262 redis "docker-entrypoint.s…" 25 hours ago Up 25 hours 6379/tcp, 0.0.0.0:8021->8021/tcp, :::8021->8021/tcp cool_ganguly
六、容器的提交
备注：运行一个基础的centos镜像，在容器内安装vim，然后提交镜像。
新的镜像再运行出的容器，默认就有vim功能。
1.运行容器安装vim
[root@node1 ~]# docker run -it centos:7.8.2003 bash
[root@680cce5c0b5f /]# yum install -y vim
