Aspnetcode与非root用户在Linux中运行

Question

我试图用非root用户在docker映像（继承自microsoft/aspnetcore）内运行一个veery简单的hello world aspnetcore应用程序，并且出现此错误：

crit: Microsoft.AspNetCore.Server.Kestrel[0] Unable to start Kestrel. System.AggregateException: One or more errors occurred. (Error -13 EACCES permission denied) ---> Microsoft.AspNetCore.Server.Kestrel.Internal.Networking.UvException: Error -13 EACCES permission denied at Microsoft.AspNetCore.Server.Kestrel.Internal.Networking.Libuv.ThrowError(Int32 statusCode) at Microsoft.AspNetCore.Server.Kestrel.Internal.Networking.Libuv.tcp_bind(UvTcpHandle handle, SockAddr& addr, Int32 flags) at Microsoft.AspNetCore.Server.Kestrel.Internal.Networking.UvTcpHandle.Bind(ServerAddress address) at Microsoft.AspNetCore.Server.Kestrel.Internal.Http.TcpListenerPrimary.CreateListenSocket() at Microsoft.AspNetCore.Server.Kestrel.Internal.Http.Listener.b__8_0(Object state) --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at Microsoft.AspNetCore.Server.Kestrel.Internal.Http.ListenerPrimary.d__12.MoveNext() --- End of inner exception stack trace --- at System.Threading.Tasks.Task.ThrowIfExceptional(Boolean includeTaskCanceledExceptions) at System.Threading.Tasks.Task.Wait(Int32 millisecondsTimeout, CancellationToken cancellationToken) at Microsoft.AspNetCore.Server.Kestrel.Internal.KestrelEngine.CreateServer(ServerAddress address) at Microsoft.AspNetCore.Server.Kestrel.KestrelServer.Start[TContext](IHttpApplication`1 application) ---> (Inner Exception #0) Microsoft.AspNetCore.Server.Kestrel.Internal.Networking.UvException: Error -13 EACCES permission denied at Microsoft.AspNetCore.Server.Kestrel.Internal.Networking.Libuv.ThrowError(Int32 statusCode) at Microsoft.AspNetCore.Server.Kestrel.Internal.Networking.Libuv.tcp_bind(UvTcpHandle handle, SockAddr& addr, Int32 flags) at Microsoft.AspNetCore.Server.Kestrel.Internal.Networking.UvTcpHandle.Bind(ServerAddress address) at Microsoft.AspNetCore.Server.Kestrel.Internal.Http.TcpListenerPrimary.CreateListenSocket() at Microsoft.AspNetCore.Server.Kestrel.Internal.Http.Listener.b__8_0(Object state) --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at Microsoft.AspNetCore.Server.Kestrel.Internal.Http.ListenerPrimary.d__12.MoveNext()<---

似乎aspnetcore不能没有root权限运行，而且在某些情况下具有非常有限的安全策略root用户不允许运行泊坞窗图像的主要过程。

是否有任何方式在非root用户的Linux中运行aspnetcore应用程序？

由于相同的安全策略，Sudo选项无效。

谢谢，

最后问题是，我试图使用端口80绑定我的应用程序。如果您使用更高的端口，即5000.没有权限问题。
