背景说明

使用Docker过程中需要记住一些辅助命令，此时相对比较费脑子，这里整理了快捷命令。

解决方案

创建脚本文件idocker并放置至目录/usr/local/bin/下

#!/bin/bash
#example:
#params $2 ：第二个参数表示
#idocker in mysql
if [ "$1" == "reset" ];then
    docker stop  $(docker ps -q )
    docker rm  $(docker ps -a -q )
fi
if [ "$1" == "images" ];then
    docker images --format "table {{.Repository}}:{{.Tag}}\t{{.ID}}\t{{.CreatedAt}}"
fi
if [ "$1" == "ips" ];then
    docker inspect --format "{{.Name}}  {{.Config.Image}}  {{.Config.Hostname}}  {{.NetworkSettings.IPAddress}}" $(docker ps -q)
fi
if [ "$1" == "ps" ];then
    docker ps  --format  "table {{.ID}}\t{{.Names}}\t{{.Image}}\t{{.Networks}}\t{{.Status}}\t{{.Ports}}"
fi
if [ "$1" == "search" ];then
    for Repo in $* ; do
        curl -s -S "https://registry.hub.docker.com/v2/repositories/library/$Repo/tags/" | \
        sed -e 's/,/,\n/g' -e 's/\[/\[\n/g' | \
        grep "name" | awk -F\" '{print $4;}' | \
        sort -fu | \
        sed -e "s/^/${Repo}:/"
    done
fi
if [ "$1" == "in" ];then
    docker exec -it $2 /bin/bash
fi
if [ "$1" == "ip" ];then
    docker inspect --format "{{.NetworkSettings.IPAddress}}" $2
fi
if [ "$1" == "volumes" ];then
    docker inspect --format "{{.Config.Volumes}}"  $2
fi
if [ "$1" == "start" ];then
    if [ "$2" == "yii" ];then
      sudo /usr/local/bin/docker-compose -f /tmp/advanced/docker-compose.yml start
    fi
fi
if [ "$1" == "stop" ];then
    if [ "$2" == "yii" ];then
      sudo /usr/local/bin/docker-compose -f /tmp/advanced/docker-compose.yml stop
    fi
fi

!/bin/bash指定shell解释器

赋予可执行权限

[root@template ~]# chmod +x /usr/local/bin/idocker 
[root@template ~]# idocker ps
CONTAINER ID   NAMES     IMAGE     NETWORKS                 STATUS        PORTS

进入容器

[root@template ~]# docker ps
CONTAINER ID   IMAGE     COMMAND                  CREATED          STATUS          PORTS     NAMES

[root@template ~]# idocker in d91aa5eac508
root@d91aa5eac508:/# 
root@d91aa5eac508:/# exit
exit
[root@template ~]#

容器主机

[root@template ~]# idocker ip d91aa5eac508
