如何克服对官方推送中docker push拒绝的资源的访问 [英] How to overcome access to resource denied for docker push in official tutorial

问题描述

我用谷歌搜索并看到了这个，但是我不知道它在说什么关于图像标签等：链接

I googled and saw this but I don't know what it is saying about image tags, etc: link

我正在尝试在此处完成本教程：教程正式的Docker

I am trying to complete the tutorial here: tutorial official Docker

这是我的 docker镜像的输出

nobu@nobu-ThinkPad-T420:~/docker/docker-curriculum/flask-app$ docker images

prakhar1989/static-site   latest              f01030e1dcf3        2 years ago         134MB

我不明白的是上面哪列显示了图像名称？我看到一列用于回购的列，然后是用于ID的列，但似乎都不符合要求，本教程跳过了这一关键信息。

What I don't understand is which column above shows the image name? I see a column for repo and then for ID but neither seems to fit the bill and the tutorial skips over this key piece of info.

我能够在 localhost：8888 上运行该应用程序。

I was able to run the app on localhost:8888.

我不知道为什么要这么做：

I don't know why I am getting:

nobu@nobu-ThinkPad-T420:~/docker/docker-curriculum/flask-app$ docker push prakhar1989/catnip
The push refers to repository [docker.io/prakhar1989/catnip]

我在Docker Hub上有一个帐户，并建立了一个公共存储库。
有人可以提示我需要输入什么命令来推动此操作吗？

I have an account on Docker Hub and set up a public repository. Can someone give me hints on what command I need to enter to push this?

推荐答案

这是我犯的一个常见错误，以为这可能对某人有所帮助。

Here is a common mistake I make, thought this might help someone.

确保在登录和推送期间始终一致地使用 sudo 。 .ie：

Make sure you are consistent in using sudo across login and push. .i.e:

1. docker登录后应始终跟随 docker push 和


2. sudo docker登录后应始终跟随 sudo docker push

1. docker login should always be followed by docker push and
2. sudo docker login should always be followed by sudo docker push

这是因为 sudo docker 和 docker 是系统中的不同文件。

This is because of the config for sudo docker and docker are different files in the system.
