Building multiple images from different dockerfiles

[darrylb-github]

Description

I have two Dockerfiles I want to build as part of mvn docker:build. They are located in a sub dir with a layout like so:

- pom.xml
- docker/
-- image1/
--- Dockerfile
-- image2/
--- Dockerfile

When running mvn docker:build I want it to build two images - one for each dockerfile.

How to reproduce

Simplified example:

            <plugin>
                <groupId>com.spotify</groupId>
                <artifactId>docker-maven-plugin</artifactId>
                <version>0.4.13</version>

                <executions>
                    <execution>
                        <id>image1</id>
                        <goals>
                            <goal>build</goal>
                        </goals>
                        <configuration>
                            <imageName>image1</imageName>
                            <dockerDirectory>docker/image1</dockerDirectory>
                            <imageTags>
                                <imageTag>${project.version}</imageTag>
                                <imageTag>latest</imageTag>
                            </imageTags>
                        </configuration>
                    </execution>

                    <execution>
                        <id>image2</id>
                        <goals>
                            <goal>build</goal>
                        </goals>
                        <configuration>
                            <imageName>image2</imageName>
                            <dockerDirectory>docker/image2</dockerDirectory>
                            <imageTags>
                                <imageTag>${project.version}</imageTag>
                                <imageTag>latest</imageTag>
                            </imageTags>
                        </configuration>
                    </execution>
                </executions>

            </plugin>

What do you expect

I expect it to build two images (image1 and image2) using the two different dockerfiles (docker/image1/Dockerfile and docker/image2/Dockerfile).

What happened instead

Exception caught: Must specify baseImage if dockerDirectory is null

It expects configuration outside of the executions and if I do this for one image and leave the other in the executions, it doesn't execute both - only the one outside executions.

Should this be possible? Any other ways to do this? I can include multiple plugin definitions but maven warns about them being duplicated: [WARNING] 'build.plugins.plugin.(groupId:artifactId)' must be unique but found duplicate declaration of plugin com.spotify:docker-maven-plugin

Software:

• docker version: 17.03.1-ce-mac12 (17661)
• docker-maven-plugin version: 0.4.13
• maven version: 3.5.0

Is there any update on this? I am looking for similar functionality.

I think this is because there is a default execution of docker:build added to the package phase, if you name one of your <executions> with <id>default</id> then I believe it would be supplying the configuration for the default execution.

Any news on this?
