如何将kafka信任存储位置的绝对路径传递给Spring boot本机映像

Question

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

但我有一个问题要通过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的位置。

• Spring靴：2.4.5
• Spring原生：0.9.2
• graalvm： graalvm-ce-java8-21.0.0.2

我的信任库文件位于以下路径中

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

那么当消息到来时，错误就发生了。

如果没有本机映像，此应用程序将正常工作。

如何将绝对路径传递给本机映像？

Answer 1

我自己解决这个问题。

我将 docker 卷设置为链接主机中的信任文件。

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
