一。镜像基础

 

一。基于容器制作镜像

　　1. 查看并关联运行的容器

[gh@localhost ~]$ docker container lsCONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES4da438fc9a8e        busybox             "sh"                2 days ago          Up 3 seconds                            aaaaa[gh@localhost ~]$ docker container attach aaaaa/ #

　　2. 创建文件夹和文件

/ # mkdir /var/html/ # vi /var/html/index.html/ # cat /var/html/index.html............httpd.........../ #

　　3. 查看httpd服务帮助

/ # which httpd/bin/httpd/ # httpd -h-f        前台运行-h        家目录/ #

　　4. 制作镜像

---- docker container commit --help

-a：作者信息

-c：修改COMMAND，即容器主程序

-m：说明

-p：暂停容器

[gh@localhost ~]$ docker container commit -a "name 
     
      " -c 'CMD ["/bin/httpd","-f","-h","/var/html"]' -p aaaaa myhttpd:v9.0sha256:9fdc2c89794f1d716a8ef3c90e4109991210e48fed46fa3f76dd9d35cc2e636f[gh@localhost ~]$ docker image ls |grep "myhttpd"myhttpd             v9.0                9fdc2c89794f        18 seconds ago      1.13MB[gh@localhost ~]$
     

　　5. 运行镜像

[gh@localhost ~]$ docker container run --name httpd -d myhttpd:v9.0 e51a67a0346bd766b0716d6e0b2f5c101d98d45a0afd04a5b7f6ebc8007c24e1[gh@localhost ~]$ docker container lsCONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS               NAMESe51a67a0346b        myhttpd:v9.0        "/bin/httpd -f -h /v…"   6 seconds ago       Up 5 seconds                            httpd4da438fc9a8e        busybox             "sh"                     2 days ago          Up 6 minutes                            aaaaa[gh@localhost ~]$

　　6. 访问服务

[gh@localhost ~]$ curl 172.17.0.3............httpd...........[gh@localhost ~]$

　　7. 与容器关联

[gh@localhost ~]$ docker container exec -it httpd /bin/sh/ # ps -ePID   USER     TIME   COMMAND    1 root       0:00 /bin/httpd -f -h /var/html   11 root       0:00 /bin/sh   16 root       0:00 ps -e/ #

 　　8. 登陆阿里云仓库（密码保存在家目录 .docker/config.json）

[gh@localhost ~]$ docker login --username=1596430280@qq.com registry.cn-shenzhen.aliyuncs.comPassword: Login Succeeded[gh@localhost ~]$

　　9. 修改标签（阿里云仓库里有操作说明）

[gh@localhost ~]$ docker image ls |grep "myhttpd"myhttpd             v9.0                9fdc2c89794f        13 hours ago        1.13MB[gh@localhost ~]$ docker image tag 9fdc2c89794f registry.cn-shenzhen.aliyuncs.com/ghh/test:v9.9[gh@localhost ~]$ docker image ls |grep "9fdc2c89794f"myhttpd                                      v9.0                9fdc2c89794f        13 hours ago        1.13MBregistry.cn-shenzhen.aliyuncs.com/ghh/test   v9.9                9fdc2c89794f        13 hours ago        1.13MB[gh@localhost ~]$

　　10. 推送镜像

[gh@localhost ~]$ docker image push registry.cn-shenzhen.aliyuncs.com/ghh/test:v9.9The push refers to repository [registry.cn-shenzhen.aliyuncs.com/ghh/test]49946ae5d4d2: Pushed 6a749002dd6a: Pushed v9.9: digest: sha256:096ff2618334d8c79750770c1ac20ba6d8f33c6945dafaa7ae17bbbe3eafe5a2 size: 734[gh@localhost ~]$
