基于容器制作镜像

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 ls CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 4da438fc9a8e 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 <abc@163.com>" -c 'CMD ["/bin/httpd","-f","-h","/var/html"]' -p aaaaa myhttpd:v9.0 sha256:9fdc2c89794f1d716a8ef3c90e4109991210e48fed46fa3f76dd9d35cc2e636f [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 ls CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES e51a67a0346b myhttpd:v9.0 "/bin/httpd -f -h /v…" 6 seconds ago Up 5 seconds httpd 4da438fc9a8e 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 -e PID USER TIME COMMAND1 root 0:00 /bin/httpd -f -h /var/html11 root 0:00 /bin/sh16 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.com Password: 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 1.13MB registry.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:v9.9 The push refers to repository [registry.cn-shenzhen.aliyuncs.com/ghh/test] 49946ae5d4d2: Pushed 6a749002dd6a: Pushed v9.9: digest: sha256:096ff2618334d8c79750770c1ac20ba6d8f33c6945dafaa7ae17bbbe3eafe5a2 size: 734 [gh@localhost ~]$
