This action packages and pushes a Spring Boot app to Google Container Registry. In order to update the running deployment to the latest image, please use the update GKE deployment action.

Setting up your Spring Boot Application

Java Version

This action allows you to specify the java version you want by providing an option. By default it runs on JDK 17.

Environment Variables

Before you use this action in your workflow please make sure to evaluate if you need to pass in environment variables to your application. Under the hood, this custom action uses the bootBuildImage command to dockerize your application. In order to pass in environment variables (if any), make sure to update and add the following block to code to your build.gradle file:

bootBuildImage {
    environment = [
            "BPE_DELIM_JAVA_TOOL_OPTIONS" : " ",
            "BPE_APPEND_JAVA_TOOL_OPTIONS" : "-Denvironment_variable_key_1=environment_variable_value_1 -Denvironment_variable_key_2=environment_variable_value_2"
    ]
}

For a full list of other options to customize your docker image please refer to this documentation.

To set the version of Java, please use the following code block and update the version of Java to the one you would like to use:

bootBuildImage {
    targetJavaVersion = JavaVersion.VERSION_17
}
