Win上安裝docker使用
1、安裝mysql鏡像
# 拉取docker鏡像,:[version]指定版本，不加則為latest
docker pull mysql:[version]
拉取mysql鏡像
2、制作docker容器
#啟動(dòng)mysql
docker run --name myDockerMysql -e MYSQL_ROOT_PASSWORD=521379 -dp 3307:3306 mysql
啟動(dòng)mysql
2、安裝centos
# 拉取docker鏡像,:[version]指定版本，不加則為latest
docker pull centos:[version]
centos
#啟動(dòng)
docker run --name mycentos -dp 8888:8888 centos
啟動(dòng)
3、docker命令
#查看所有鏡像
docker images
#查看所有容器
docker ps -a
#docker修改centos的root密碼
rpm -e cracklib-dicts --nodeps
yum install cracklib-dicts
passwd root
批量操作
1、批量停止所有容器
docker stop docker ps -a -q
2、批量刪除所有容器
docker rm docker ps -a -q
3、批量刪除所有鏡像
docker rmi docker images -q
4、按條件刪除鏡像（沒(méi)有打標(biāo)簽）
1.>docker rmi docker images -q | awk '/^<none>/ { print $3 }' //鏡像名包含關(guān)鍵字
2.>docker rmi --force docker images | grep doss-api | awk '{print $3}' //其中doss-api為關(guān)鍵字
docker save -o ./xxx.tar [image-name]
docker load -i xxx.tar
