spring-boot - 如何将kafka信任存储位置的绝对路径传递给spring boot native image

问题描述

我正在尝试使用 spring-native 创建使用 kafka ssl 的 spring 应用程序的本机映像。

但是我有一个问题要传递 kafka 信任库路径的绝对路径。

因为本机映像无法知道信任库路径在哪里。

我的信任库文件位于以下路径

src
  - main
    - resources
      - truststore
         mytrustsotre.jks

# Kafka properties
spring:
  kafka:
    ssl:
      trustStorePassword: "password"
      trustStoreLocation: "classpath:truststore/mytrustsotre.jks"

Maven 插件构建参数

            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <image>
                        <builder>paketobuildpacks/builder:tiny</builder>
                        <env>
                            <BP_NATIVE_IMAGE>true</BP_NATIVE_IMAGE>
                            <BP_NATIVE_IMAGE_BUILD_ARGUMENTS>
                                -H:IncludeResourceBundles=sun.security.util.Resources
                                -H:IncludeResources=truststore/mytrustsotre.jks
                            </BP_NATIVE_IMAGE_BUILD_ARGUMENTS>
                        </env>
                    </image>
                </configuration>
            </plugin>

构建并运行应用程序

mvn spring-boot:build-image -Dspring-boot.build-image.imageName=my.way.com/app:1.0.0-SNAPSHOT

...
...

docker run -it -e "SPRING_PROFILES_ACTIVE=default" \
-e "--spring.application.name=app" \
my.way.com/app:1.0.0-SNAPSHOT

然后在消息到来时发生错误。

如果没有本机图像，此应用程序可以正常工作。

如何将绝对路径传递给本机图像？

解决方案

我自己解决了这个问题。

我将 docker 卷设置为链接到我的主机中的信任文件。

docker run -it -v /my/resources:/app/resources \
-e "SPRING_PROFILES_ACTIVE=default" \
-e "--spring.application.name=app" \
my.way.com/app:1.0.0-SNAPSHOT
