1.将容器直接提交成镜像
[root@localhost ~]# docker commit 8ecc7f6b9c12 nginx:1.1

[root@localhost ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
nginx 1.1 9a2bb94ba6d8 7 seconds ago 236MB
rockylinux 9.3 583a894199be 5 hours ago 181MB将容器的文件挂载到宿主机目录下，容器删除掉，它的文件也会存在
[root@lvs-server ~]# docker run -itd -e MYSQL_ROOT_PASSWORD=QianFeng@123 -v /opt/data:/var/lib/mysql mysql:8.0.38-oraclelinux9

#ADD souce dest
#拷贝文件到镜像内
#1.支持网络资源拷贝，后面要加域名，如：http://www.example.com/file.tar.gz
#2.如果拷贝的是tar包，会自动的将tar包内的东西一同拷贝到镜像内，会自动解压
#1和2不可以同时使用
#给镜像打标签
