Docker:消息仅显示不受支持

Question

我正在使用 linux 容器在 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”]

现在从 cli 中，我输入了以下内容。

heroku login
heroku container:login
heroku create forceci
docker build -t force_ci:v1 .

C:\ForceCI\forceCI\forceCI>docker images

openjdk             8-jdk-alpine        54ae553cb104        5 weeks ago         103MB

现在我做了 heroku container:push web --app forceci :

C:\ForceCI\forceCI\forceCI>heroku container:push web --app forceci

我得到不支持的错误。

现在我做了 docker 图像来检查已经构建了哪些图像，我得到了这个:

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？

Answer 1

我通过更改 Dockerfile 的最后一行解决了这个问题.

最初，Visual Studio 模板提供的文件使用以下内容在容器内启动 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
现在它就像一个魅力。
