[FIXED] specify "--network=host" using spring-boot:build-image

Issue

I've been using docker build this way: docker build --network host -t foo/bar

But now I'm trying to make use of spring-boot:build-image

mvn spring-boot:build-image -Dspring-boot.build-image.imageName=foo/bar

but this way --network option is not provided. Unfortunately didn't find a way how to properly provide the option.

Question: How can I provide --network with spring-boot:build-image (assuming I need to provide this option during build and not during run)?

Solution

So I found the answer. Apparently this feature is available since Spring Boot 2.6.0-M2 see: https://github.com/spring-projects/spring-boot/issues/25876 and https://github.com/spring-projects/spring-boot/releases/tag/v2.6.0-M2

Starting with this version you can try to do something like

<project>
    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <image>
                        <network>host</network>
                    </image>
                </configuration>
            </plugin>
        </plugins>
    </build>
</project>
