我在Maven项目中使用io.fabric8:docker-maven-plugin:0.28.0
,我需要在不同阶段构建2个不同的Docker映像:
- 一个用于
integration-test
阶段的一个,用于运行一些数据库以进行集成测试。我将使用项目中的一些资源构建它(定义模式的SQL文件)。 - 最后一个测试通过(也许在
package
期间),并使用完整的应用程序。
我的问题是仅构建了第一个图像。
我试图在<execution>
元素的<configuration>
中引用图像别名,但似乎不起作用。仅考虑第一个图像:
$ mvn install
...

未创建第二张图像,当应构建第二个图像时,也使用第一个图像的ID:
$ docker images "example/*"
REPOSITORY TAG IMAGE ID CREATED SIZE
example/db-test latest d8233ab899d4 7 days ago 1.2MB
会有另一种方法吗?
这是我的pom.xml

为了保持示例简单,我使用busybox
和alpine
作为基本图像,但这无关。
尝试将所需图像的完整配置移至执行中,而不是使用全局插件配置。
