Question

我正在尝试运行JavaFX SparkML应用程序的Docker映像。我可以创建一个映像，但是在运行该映像时，出现与JavaFX相关的错误。

这是我的第一个Docker映像，如果能为我指明正确的方向，我将不胜感激。我已经在线搜索并尝试了几种将JavaFX添加到我的docker镜像中的方法，但是我仍然遇到相同的错误！

我的Dockerfile：

# build
#FROM maven AS build

FROM maven:3.5.3-jdk-8 AS build
WORKDIR /usr/src/app
COPY pom.xml .

RUN apt-get update
RUN apt-get install -y --no-install-recommends openjfx && rm -rf /var/lib/apt/lists/*

# Install apt-utils
RUN apt-get update
RUN apt-get install -y apt-utils
RUN apt-get install -y curl

# Install openjfx
#RUN apt-get update
#RUN apt-get install -y openjfx

RUN mvn -f /usr/src/app/pom.xml clean package

#RUN mvn -B -e -C -T 1C org.apache.maven.plugins:maven-dependency-plugin:3.1.1:go-offline
COPY . .
#RUN mvn -B -e -o -T 1C verify



# package without maven
FROM openjdk

COPY --from=build /usr/src/app/target/*.jar ./bda-1.0.0-SNAPSHOT.jar

RUN chmod 777 *.jar

EXPOSE 8080  
CMD ["java","-jar","./bda-1.0.0-SNAPSHOT.jar"]

以及由此产生的错误：

Answer 1

JDK仍包含JavaFX。您的stacktrace包含JavaFX类。所以我想这不是您的实际问题。

泊坞窗映像不直接支持UI。它只是一个与本地桌面隔离的容器。

但是似乎可以将docker容器配置为使用本地X-Server渲染UI。我找到了以下示例：https://medium.com/@SaravSun/running-gui-applications-inside-docker-containers-83d65c0db110

基本上，您必须将所需的X-Server库安装到容器中并配置显示，网络和卷，以使其正常工作。

从Docker映像运行JavaFX Spark应用程序时发生错误
