quarkus

example:

• index
  
• quirkus (folder: integration-tests)
  
• quarkus-quickstarts
  

log:

• how to use
• LOG.level("string");  (ex: LOG.debug("小寫"))

• $ ./mvnw compile quarkus:dev -Dquarkus.log.file.enable=true -Dquarkus.log.file.rotation.max-file-size=10M -Dquarkus.log.file.rotation.max-backup-index=20

• it will save in "target" folder

DataBase:

• quarkus.hibernate-orm.database.generation=drop-and-create | update | none 

編譯成Native Image執行檔:

• $ ./mvnw package -Pnative -Dquarkus.native.container-runtime=docker
  (可以在「target」目錄下看到XXX-runner的執行檔)

GraalVM Native Image:

• 承上
  $ docker build -f src/main/docker/Dockerfile.native -t REPOSITORY_name .
  $ docker run -d -p 8080:8080 REPOSITORY_name
  (可用「docker stats」查看其使用之記憶體空間)
  

Dockerfile and run.sh:

• FROM registry.access.redhat.com/ubi8/ubi-minimal
  WORKDIR /work/
  COPY target/*-runner /work/application
  RUN chmod 775 /work
  EXPOSE 8080
  CMD ["./application", "-Dquarkus.http.host=0.0.0.0", \
                        "-Dquarkus.log.file.enable=true", \
                        "-Dquarkus.log.file.rotation.max-file-size=10M", \
                        "-Dquarkus.log.file.rotation.max-backup-index=20"]    

• #!/bin/bash
  
  docker run -it  \
          --privileged \
          -v $HOME/hello/:/work \  (如果word是執行檔，要將word執行檔放在host端)
          -p 8080:8080 \
          hello:word
