java - Docker - "image operating system "linux“无法在此平台上使用”尝试构建镜像时

Question

我按照此链接使用 Spring Boot 项目创建 docker 镜像 https://dzone.com/articles/deploying-spring-boot-on-docker

已经切换到 Windows 容器

操作系统:Windows 10 专业版

Docker版本:2.1.0.1

引擎:19.03.1

当我尝试构建图像时，我收到此错误:

  A:\Projects\Docker\dockerDemo>docker build -f DockerFile -t dockerdemo .
  Sending build context to Docker daemon  99.84kB
  Step 1/4 : FROM java:8
  8: Pulling from library/java
  image operating system "linux" cannot be used on this platform

Docker 文件

  FROM java:8
  EXPOSE 8080
  ADD /target/dockerdemo.jar dockerdemo.jar
  ENTRYPOINT ["java", "-jar", "dockerdemo.jar"]

提前致谢!!!

Answer 1

您需要“openjdk”而不是“java”

https://hub.docker.com/_/openjdk

这将是您的 Dockerfile:

FROM openjdk:[some_tag]
EXPOSE 8080
ADD /target/dockerdemo.jar dockerdemo.jar
ENTRYPOINT ["java", "-jar", "dockerdemo.jar"]

这是我通过 java 查询发现的:
