如何复制文件到docker容器中（实操）

步骤一：查看docker镜像

命令 docker images 锁定容器tomcat

[root@ecs- ~]# docker imagesREPOSITORY TAG                 IMAGE ID            CREATED             SIZEhub.cloudx5.com/justep/gateway-init    1.0                 3d26e9ba2df0        2 years ago         92.1MBhub.cloudx5.com/justep/dbrest          1.0.1               780b3ae16949        2 years ago         106MBhub.cloudx5.com/justep/adminer         1.0                 a16d1fd76db4        2 years ago         145MBcertbot/certbot                        latest              994e18b9d74d        2 years ago         92.2MB                   c99efc745e9b        3 years ago         92.1MBhub.cloudx5.com/justep/database-init   1.0                 2fe4f106e3ac        3 years ago         141MB                   886d8c169d03        3 years ago         145MBhub.cloudx5.com/justep/kong            0.11.2              6c215f862793        3 years ago         147MBhub.cloudx5.com/justep/minio           1.0.2               7e4ae5d3ea35        3 years ago         281MB                   6d131f0b7034        3 years ago         104MBhub.cloudx5.com/justep/tomcat          8                   f550faa880e8        3 years ago         111MBhub.cloudx5.com/justep/java            8-jre               58445151ac69        3 years ago         90.4MB

步骤二：查找容器确定容器名

命令 docker ps -a 或者直接找对应的 docker ps -a | grep tomcat 查看最后一个属性 names 我这里是tomcat-chuangzhidao

[root@ecs-chuangzd ~]# docker ps -a | grep tomcatdd43969828b5        hub.cloudx5.com/tomcat:8            "/usr/local/bin/dock…"   18 hours ago        Up 14 hours                 8080/tcp      tomcat-chuangzhidao

步骤三：根据容器名获取容器长ID

命令 docker inspect -f '{{.ID}}' 容器名

[root@ecs-chuangzd ~]# docker inspect -f '{{.ID}}' tomcat-chuangzhidaodd43969828b5450ec6d45e070ae82ba4c31daae8a9c2533e0495892aa137d835

步骤四：拷贝文件到容器指定位置

命令 docker cp 文件 长ID：目录，这里我从根目录上传至容器根目录

[root@ecs-chuangzd ~]# docker cp /2c3e75497b243b157bb55b96ec06e145.txt dd43969828b5450ec6d45e070ae82ba4c31daae8a9c2533e0495892aa137d835:/

步骤四：进容器查看操作

命令 docker exec -it 【 CONTAINER ID】 /bin/bash

CONTAINER ID就是docker ps -a 第一个属性名 我这里是dd43969828b5

[root@ecs-chuangzd ~]# docker exec -it dd43969828b5  /bin/bashbash-4.4# lsBUILDING.txt     NOTICE         RUNNING.txt  include  native-jni-lib  workCONTRIBUTING.md  README.md      bin          lib      tempLICENSE          RELEASE-NOTES  conf         logs     webappsbash-4.4# cd /bash-4.4# ls2c3e75497b243b157bb55b96ec06e145.txt  data  etc   media  root  srv    tmp  workUsers     dev   home  mnt    run   store  usrbin       dist  lib   proc   sbin  sys    varbash-4.4#
