我正在带有Linux容器的Windows上运行docker，并尝试将带有docker文件的spring boot项目推送到heroku。
Docker文件：
FROM openjdk:8-jdk-alpine
VOLUME /tmp
ARG JAR_FILE
ADD ${JAR_FILE} forceCI-0.0.1-SNAPSHOT.jar
ENTRYPOINT [“java”,”-Djava.security.egd=file:/dev/./urandom”,”-jar”,”/forceCI-0.0.1-SNAPSHOT.jar”]

现在来自cli，我输入了以下内容。
heroku login
heroku container:login
heroku create forceci
docker build -t force_ci:v1 .

现在我做了heroku container:push web --app forceci：
C:\ForceCI\forceCI\forceCI>heroku container:push web --app forceci

=== Pushing web (C:\ForceCI\forceCI\forceCI\Dockerfile)
The push refers to repository [registry.heroku.com/forceci/web]

! Error: docker push exited with 1
我得到了不支持的错误。
现在我做了docker镜像来检查已经构建了哪些镜像，我明白了：
C:\ForceCI\forceCI\forceCI>docker images
REPOSITORY TAG IMAGE ID CREATED SIZE

然后我想将已经构建的图像推送到heroku，但是仍然收到不支持的消息。
C:\ForceCI\forceCI\forceCI>docker tag force_ci:v1 registry.heroku.com/forceci/web
C:\ForceCI\forceCI\forceCI>docker push registry.heroku.com/forceci/web

有人可以在这里帮忙吗？

答案 0 :(得分：4)
我通过更改Dockerfile的最后一行来解决此问题。
最初，Visual Studio模板提供的文件使用以下内容在容器中启动Webapp：
ENTRYPOINT ["dotnet", "YourAppName.dll"]
相反，根据Heroku文档，您应该使用以下内容：
CMD ASPNETCORE_URLS=http://*:$PORT dotnet YourAppName.dll
现在，它就像一种魅力。
答案 1 :(得分：0)
您应将Dockerfile中的ENTRYPOINT替换为CMD。参见heroku docs：
CMD是必需的。如果缺少CMD，注册表将返回错误 CMD将始终由外壳执行，以便使配置var可用于您的进程。要执行单个二进制文件或使用没有外壳的图像，请使用ENTRYPOINT
