I am running dotnet core 2.0 console project. Ran into the following error when trying to run it from Docker.

A fatal error was encountered. The library 'libhostpolicy.so' required to execute the application was not found in '/app'.

解决方案

After some googleing I found this:
https://github.com/aspnet/aspnet-docker/issues/301

I'm not certain what caused it but it seems to have gone away. It's probably because I had a case mismatch of appSettings.json instead of appsettings.json which meant that the file was not being loaded. Terrible error though.

In my case it was that I had forgot to put appsettings.json to copy on builds.

Hope this helps someone else and get's higher on google searches.
