I have a console application with Dotnet 6.0. My dockerfile script built successfully however, it failed at runtime when deploying to the server with Error : /bin/sh: [./Filename]: not found

my image ran fine when it's dotnetcore 3.1 and with script runtime-deps:3.1-alpine AS base. So why does it require /bin/sh: when it's in dotnet 6.0. How do you fix this issue? Any help is greatly appreciated.

CodePudding user response：

Change the entrypoint at the end of your dockerfile:

ENTRYPOINT ["./Filename"]
