无法将Docker映像推送到Docker Hub;请求的对资源的访问被拒绝

问题描述

我想将许多新的Docker映像推送到Docker Hub。我已经在Docker Hub上创建了所有空的存储库，并添加了具有所需特权级别的团队和成员。这些用户之一是jenkinsrelease。该用户是团队mihbuild和mihrelease的成员。以一个仓库meanwhileinhell/search-server为例，每个团队的权限分别为mihbuild - Read only和mihrelease - Read & write。

我正在使用bmuschko的Gradle Docker API插件从我的Jenkins构建创建的运行Ubuntu的EC2从属实例构建和推送映像。但是，每当我尝试将映像推送到Docker Hub（./gradlew dockerPushImage）时，都会出现以下错误：

> Task :search-server:dockerPushImage FAILED
Pushing image 'meanwhileinhell/search-server:0.0.1-SNAPSHOT'.

* What went wrong:
Execution failed for task ':search-server:dockerPushImage'.
> Could not push image: denied: requested access to the resource is denied

我已在命令行上登录Docker，并说我已成功登录：

docker login -u jenkinsrelease -p pasword1234

Login Succeeded

看着我的config.json，我可以看到auth部分已更新：

-rw------- 1 ubuntu ubuntu 184 Sep 2 08:31 /home/ubuntu/.docker/config.json

{
        "auths": {
                "https://index.docker.io/v1/": {
                        "auth": "wrjauhgfoihfwu1y2tyed6uyiom="
                }
        },"HttpHeaders": {
                "User-Agent": "Docker-Client/18.06.3-ce (linux)"
        }
}

我还尝试了注销并再次登录，还登录了registry-1.docker.io和index.docker.io/v2，它们将相应的条目添加到了config.json中。我尝试登录hub.docker.com，但报告了一个错误（我知道这与docker.io相同）：

{
        "auths": {
                "https://index.docker.io/v1/": {
                        "auth": "wrjauhgfoihfwu1y2tyed6uyiom="
                },"index.docker.io": {
                        "auth": "wrjauhgfoihfwu1y2tyed6uyiom="
                },"registry-1.docker.io": {
                        "auth": "wrjauhgfoihfwu1y2tyed6uyiom="
                }
        },"HttpHeaders": {
                "User-Agent": "Docker-Client/18.06.3-ce (linux)"
        }
}

我不知道它是否有所不同，但这是第一次将图像推送到这些存储库，它们目前都是空的。

解决方法

这是所使用的bmuschko Docker插件版本中的错误。是在6.1.2上，更新到6.6.1解决了该问题。
