Question

My application is running with spring-boot:2.3.10.RELEASE and eclipse-temurin:8u392-b08-jdk-alpine, the core code following,

@SpringBootApplication
public class App {

  private static final Logger logger = LoggerFactory.getLogger(App.class);

  public static void main(String[] args) throws Exception {
    SpringApplication.run(App.class, args);

    String[] names = GraphicsEnvironment.getLocalGraphicsEnvironment()
        .getAvailableFontFamilyNames();

    logger.info("Found " + names.length + " fonts:");

    for (String name : names) {
      logger.info(name);
    }
  }
}

my Dockerfile following,

FROM eclipse-temurin:8u392-b08-jdk-alpine
WORKDIR /app/
COPY target/springboot-demo-1.0.jar app.jar
ENV JAVA_OPTS=""
ENV ARGS=""
EXPOSE 8080
ENTRYPOINT ["sh", "-c","java $JAVA_OPTS -Djava.awt.headless=true -Djava.security.egd=file:/dev/./urandom -jar /app/app.jar $ARGS"]

my docker build command is

docker build -t springboot-demo:1.0 -f Dockerfile .

my docker run command is

docker run -d --name springboot-demo -p 8080:8080 springboot-demo:1.0

then the application throwing exception

How should I solve this problem?

Context

@hzfq try adding an install for libfreetype6 as part of your docker file

[hzfq]

thx, I tried the above method, but the problem still exists. End, I resolved the problem through adding libgcc as part of Dockerfile.

In addition, I recommend adding freetype and libgcc to the dockerfile because these two libraries are used frequently.

Finally, in the process of solving the above problem, I discovered a new problem.

# problem position: 
# https://github.com/adoptium/containers/blob/main/8/jdk/alpine/Dockerfile
rm -f /tmp/openjdk.tar.gz ${JAVA_HOME}/lib/src.zip;

Here, the correct absolute path of src.zip is ${JAVA_HOME}/src.zip
