docker compose-up-没有设置X11 DISPLAY变量，但这个程序执行了一个需要它的操作

Question

我有以下Dockerfile：

FROM adoptopenjdk/openjdk11
COPY target/VanatoareaDeDiamante.jar VanatoareaDeDiamante.jar
ENTRYPOINT ["java", "-jar", "/VanatoareaDeDiamante.jar"]

和docker-compose.yml:

services:
game:
image: 'game'
build:
context: .
ports:
- 5000:5000
container_name: game
depends_on:
- postgresdb
postgresdb:
image: postgres:14
container_name: database
restart: always
command:
-p 5433
environment:
POSTGRES_DB: piu_project
POSTGRES_USER: ${POSTGRES_USER}
POSTGRES_PASSWORD: ${POSTGRES_PASSWORD}
ports:
- 5433:5433

它是一个java GUI应用程序，我想在容器上运行它。当我写下这篇文章时，我得到了：

game          | Exception in thread "Thread-0" java.awt.HeadlessException:
game          | No X11 DISPLAY variable was set, but this program performed an operation which requires it.

一些想法？

您需要使用一个支持GUI(X11(的基本映像来构建映像，如下图所示。
