无法在Spring Boot 2.5.5中使用Docker创建自定义映像名称

Question

我正在开发小型Spring Boot微服务应用程序。当我试图创建自定义Spring映像部署到Docker引擎时，我面临着一个问题。为了创建新的自定义图像，我在POM文件的Maven插件部分使用配置元素。

错误:执行目标失败org.springframework.boot: spring-boot-maven-plugin: 2.5.5:构建过程(default-cli)在项目BankModule上:执行目标的default-cliorg.springframework.boot: spring-boot-maven-plugin: 2.5.5:构建过程失败:无法解析图像引用"kolludocker/ms1-BankModule: 0.0.1-SNAPSHOT"。图像参考必须是格式为'[domainHost:port/][path/]name[:tag][@digest]'，其中包含'path'和'name'只包含[a-z0-9]。][_][-] -& gt;[帮助1](错误)

Answer 1

工件id的名称中有大写字母。给出的错误告诉我们:

只包含[a-z0-9][.][_][-]的'path'和'name'

创建工件id "BankModule"对于"bank-module"，这将工作。

Answer 2

您是否尝试过将小写字母设置为属性?这对我(v2.6.3)来说很好，而且在我看来更优雅/紧凑:

<properties>
<spring-boot.build-image.imageName>io.bla/example/bla</spring-boot.build-image.imageName>
</properties>
