如何正确地dockerize maven项目与jib

Question

我有一个Spring Boot maven应用程序，我需要使用jib插件对其进行dockerize，并将注册表发送到azure容器注册表。注册表已设置并就绪，包括用户名、密码等。。。我的pom。xml如下所示：

                    <to>
                        <image>demo-springboot-docker-0001968</image>
                        <auth>

                </configuration>
            </plugin>

</project>

当我运行命令“mvn compile jib： build”时，我得到以下输出：

基本映像在公共docker中心存储库中。当我运行docker拉...-我可以毫无问题地拉它。

我如何调整这个pom文件，以使基础图像能够被提取？

Answer 1

我得到了同样的问题，当使用jib插件一次。

只需尝试通过在终端中点击docker logout首先注销，然后在构建mvn时添加以下选项。

-Djib.to.auth.username="your-dockerhub-username"-Djib.to.auth.password="your-dockerhub-code"

Answer 2

你认为：

基本图像位于公共码头中心回购协议中

Docker说：

$ docker pull uranagivinod/openjdk8:latest
Error response from daemon: pull access denied for uranagivinod/openjdk8, repository does not exist or may require 'docker login': denied: requested access to the resource is denied

首先执行docker注销再试一次，你会发现它实际上是一个私人图像。

Answer 3

请注意，错误是针对目标图像，而不是基本图像。

> make sure your credentials for 'registry-1.docker.io/library/demo-springboot-docker-0001968' are set up correctly.

还请注意，目标映像指向Docker Hub存储库（registry-1.Docker.io）。

如果我尝试你的用户名和密码（Docker Hub），

$ docker login -u containerregistry0001968 -p '/rG=4I26Eogai7a0/OWMKxo2x7OnHIHD'
WARNING! Using --password via the CLI is insecure. Use --password-stdin.
Error response from daemon: Get https://registry-1.docker.io/v2/: unauthorized: incorrect username or password

我得到了Jib构建日志中显示的完全相同的错误消息：

incorrect username or password

您的用户名和密码不正确。我现在就会更改您的密码，因为它们现在已公开显示。或者删除这个问题。
