无法使用 Docker 在 Spring Boot 2.5.5 中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。当我尝试创建自定义 Spring 映像以部署到 Docker 引擎时，我遇到了一个问题。为了创建新的自定义图像，我在 POM 文件的 Maven 插件部分中使用配置元素。

错误：无法在项目 BankModule 上执行 goal\norg.springframework.boot:spring-boot-maven-plugin:2.5.5:build-image\n(default-cli)：执行 goal\norg.springframework 的 default-cli。 boot:spring-boot-maven-plugin:2.5.5:build-image\n失败：无法解析图像引用\n“kolludocker/ms1-BankModule:0.0.1-SNAPSHOT”。图像引用必须采用\'[domainHost:port/][path/]name[:tag][@digest]\'格式，其中\n\'path\'和\'name\'仅包含[a -z0-9][.][_][-] -> [帮助 1]\n[错误]

Answer 1

工件 ID 的名称中包含大写字母。给出的错误说明：

'路径'和'名称'仅包含[a-z0-9][.][_][-]

一旦您将工件 ID“BankModule”设置为“bank-module”，这就会起作用。

Answer 2

您是否尝试过小写并将其设置为属性？这对我来说效果很好（v2.6.3）并且恕我直言更优雅/紧凑：

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