本文介绍如何将本地的镜像上传到镜像仓库。以及上传时遇到"denied: requested access to the resource is denied"的解决方法。 原文地址：代码汇个人博客 http://www.codehui.net/info/57.html 在上一篇文章中，介绍了使用docker快速搭建nginx+php环境，本文介绍如何把修改过的镜像上传至镜像仓库。我们需要先在 Docker Hub上注册一个账号。 查看镜像 [root@localhost ~]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE nginx latest f09fe80eb0e7 7 days ago 109MB php 7.1-fpm 7c5ccac5d47f 7 days ago 358MB 查看容器 [root@localhost ~]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 51adb2df6004 php:7.1-fpm "docker-php-entrypoif" 6 hours ago Up 6 hours 0.0.0.0:9000->9000/tcp myphp-fpm 3218b3ad4e47 f09fe80eb0e7 "nginx -g 'daemon off" 7 hours ago Up 7 hours 0.0.0.0:80->80/tcp mynginx 从容器创建一个新的镜像 [root@localhost ~]# docker commit -p -a "codehui" -m "test" 3218b3ad4e47 codehi/nginx:v1 sha256:1d8fca63675ac57bccb50f0dbdb6030e384c22ee673eecdcb04c915236778109-a :提交的镜像作者； -m :提交时的说明文字； -p :在commit时，将容器暂停。 再次查看镜像，发现了本地新提交的codehi/nginx:v1的镜像 [root@localhost ~]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE codehi/nginx v1 1d8fca63675a 21 minutes ago 109MB nginx latest f09fe80eb0e7 7 days ago 109MB php 7.1-fpm 7c5ccac5d47f 7 days ago 358MB 然后登陆到 docker hub [root@localhost ~]# docker login Login with your Docker ID to push and pull images from Docker Hub. If you don't have a Docker ID, head over to https://hub.docker.com to create one. Username: codehi Password: WARNING! Your password will be stored unencrypted in /root/.docker/config.json. Configure a credential helper to remove this warning. See https://docs.docker.com/engine/reference/commandline/login/#credentials-store Login Succeeded 将codehi/nginx:v1镜像推送到docker hub仓库中 [root@localhost ~]# docker push codehi/nginx:v1 The push refers to repository [docker.io/codehi/nginx] 67e805da8eae: Pushed 6b5e2ed60418: Mounted from library/nginx 92c15149e23b: Mounted from library/nginx 0a07e81f5da3: Mounted from library/nginx v1: digest: sha256:729b836319d3f8bd501db5e7bfadc31d1a88f996b0e756f6fb6cd6abd4408962 size: 1156登陆仓库后台查看上传成功
然后就可以在另一台服务器使用pull方法下载这个镜像 [root@localhost ~]# docker pull codehi/nginx:v1 v1: Pulling from codehi/nginx 6ae821421a7d: Already exists da4474e5966c: Already exists eb2aec2b9c9f: Already exists 96e30fa1efc1: Pull complete Digest: sha256:422535f95685c43406e378b2c59a3a6564362a683ceac4b783b9d5cee347ae17 Status: Downloaded newer image for codehi/nginx:v1 push 时报错 "denied: requested access to the resource is denied" 的解决方法报这个错说明tag需要改名字，由于之前commit的时候没有填tag，导致这块上传不上去，解决办法： [root@localhost ~]# docker tag 1d8fca63675a codehi/nginx:v1 |
