Buildpack Builder config example

Example of a java project able to build a Quarkus, Spring Boot, ... project using the DSL BuildConfig.builder()

To use it, configure the following mandatory environment variables pointing to a project (example: hello-quarkus, hello-spring) to be built as a container image

export PROJECT_PATH=<JAVA_PROJECT>
export IMAGE_REF=<IMAGE_REF> // <IMAGE_NAME> without registry or <REGISTRY_SERVER>/<REGISTRY_ORG>/<IMAGE_NAME>

Important: To avoid the docker rate limit problem, then set this CNB_ environment variable to let lifecycle to get rid of the limit:

export CNB_REGISTRY_AUTH="'{"index.docker.io":"Basic <BASE64_OF_USERNAME:PASSWORD>"}'"

// Replace `<BASE64_OF_USERNAME:PASSWORD> text with
echo -n "username:password" | base64

If you plan to push your image to a registry, then set your registry credential using these variables:

export REGISTRY_USERNAME="<REGISTRY_USERNAME>"
export REGISTRY_PASSWORD="<REGISTRY_PASSWORD>"
export REGISTRY_SERVER="docker.io"

Execute this command in a terminal:

mvn compile exec:java

You can also pass the BP_ or CNB_ environment variables:

export BP_JVM_VERSION="21"
export BP_MAVEN_BUILT_ARTIFACT="target/quarkus-app/lib/ target/quarkus-app/*.jar target/quarkus-app/app/ target/quarkus-app/quarkus"
export CNB_LOG_LEVEL=debug
etc
