I am using fabric8 maven plugin to deploy a vertx application into Openshift. My application is running with Java 11.
However, by default, the fabric8 maven plugin uses a Java 8 Docker image to create my vertx application image.
How is it possible to configure fabric8 maven plugin to use a Java 11 image ? Does it provide other images for Java > 8 ?
I fixed it for my Spring Boot application by adding from configuration to the generator. For vert.x the solution could look like this:
<plugin>
<groupId>io.fabric8</groupId>
<artifactId>fabric8-maven-plugin</artifactId>
<version>3.5.42</version>
<configuration>
<generator>
<config>
<vertx>
<from>fabric8/s2i-java:3.0-java11</from>
</vertx>
</config>
</generator>
</configuration>
</plugin>
Which tags are available for the s2i image can be looked up at the Docker Hub page: https://hub.docker.com/r/fabric8/s2i-java/tags
