OpenShift S2I Builder for Java

This Source-to-Image Builder let’s you create projects targetting Java OpenJDK 8 and built with:

• maven

• gradle

Note	If a project has a pom.xml and a build.gradle, maven will take precedence

This builder/runtime s2i image can be used with SpringBoot, Vert.X, Wildfly Swarm, DropWizard and many other microservices frameworks.

BUILD ENV Options

• APP_SUFFIX: Jar file suffix to use to locate the generated artifact to use (e.g. xxxxx${APP_SUFFIX}.jar)

• BUILDER_ARGS: Allows you to specify options to pass to maven or gradle

RUN ENV Options

• APP_OPTIONS: Options to pass to java -jar app.jar ${APP_OPTIONS}

Defaults

If you do not specify any BUILDER_ARGS, by default the s2i image will use the following:

• Maven

BUILDER_ARGS="package -Popenshift -DskipTests -Dcom.redhat.xpaas.repo.redhatga"

• Gradle

BUILDER_ARGS="build -x test"

Test in OpenShift

• First load all the needed resources in a project.

oc create -f https://raw.githubusercontent.com/raghuraman1/s2i-java/master/ose3/s2i-java-imagestream.json

• Once the builder s2i-java has been registered, you can create an app with:

  • Instant app already provided as template

  • Using the s2i-java builder image using a regular Git repository

Samples

There is a lot of example SpringBoot applications here
