Docker：入口点未执行

Question

我有以下DockerFile：

# Build runtime image
FROM microsoft/aspnetcore:2.0
WORKDIR /app
COPY ./entrypoint.sh ./app/
RUN chmod +x ./app/entrypoint.sh
CMD /bin/bash ./app/entrypoint.sh
ENTRYPOINT ["dotnet", "test.dll"]

Unhandled Exception: System.FormatException: Value for switch '/bin/bash ./app/entrypoint.sh' is missing.
Test          |    at Microsoft.Extensions.Configuration.CommandLine.CommandLineConfigurationProvider.Load()
Test          |    at Microsoft.Extensions.Configuration.ConfigurationRoot..ctor(IList`1 providers)
Test          |    at Microsoft.Extensions.Configuration.ConfigurationBuilder.Build()
Test          |    at Microsoft.AspNetCore.Hosting.WebHostBuilder.BuildCommonServices(AggregateException& hostingStartupErrors)
Test          |    at Microsoft.AspNetCore.Hosting.WebHostBuilder.Build()
Test          |    at Test.Program.Main(String[] args) in /app/Program.cs:line 19
Identity exited with code 139

这是什么意思：switch的值丢失了，我如何运行它？谢谢你的帮助

更新

请参阅此处：docker ASP.NET核心容器在mysql容器之后启动以获取更多信息。很抱歉有类似的第二个线程。请删除此线程

#!/bin/bash

echo -e "\nWaiting for the Database-Service..."

until dotnet ef database update; do
>&2 echo "SQL Server is starting up"
sleep 1
done

>&2 echo "SQL Server is up - executing command"
exec $run_cmd

Answer 1

正在发生的情况是，使用参数/bin/bash./app/entrypoint.sh启动dotnet test.dll。则test程序尝试解析这些参数并失败。这就是例外的意义所在。

您可能必须根据要实现的目标删除cmd或entrypoint。如果entrypoint.sh要接收dotnet test.dll作为参数，则还可以交换cmd和entrypoint参数。
