Right now. I try to find decision how to add nginx and kestrel ?

you suppose to build it in docker container not just to copy... — Oleg Butuzov
Can you please share the container logs? (docs.docker.com/engine/reference/commandline/logs) Also, the entry point is "BASH", are you trying to use this container as builder? If so, your build process is not correct (docs.docker.com/develop/develop-images/multistage-build). — Armando Cuevas
Sorry I didn't write. But I am recently started to study docker and how to deploy and I don't know how will be right. But i want just to deploy .net assembly in docker. No I don't want to build process because it is ready assembly. — noute
Sorry but when I try to run container without ENTRYPOINT ["bash"] I had error Error response from daemon: OCI runtime create failed: container_linux.go:345: starting container process caused "exec: \"build1\": executable file not found in $PATH": unknown docker logs — noute
Hello thx for your help. I resolve my problem. Right now. I try to find decision how to add nginx and kestrel ? — noute

Microsoft suggests to use NGINX as a reverse proxy to .NET Core applications. You need to build the image and install NGINX in your dockerfile.

For example:

FROM mcr.microsoft.com/dotnet/core/aspnet:2.2-stretch-slim AS final

# Nginx
RUN apt update && \
    apt install -y --no-install-recommends nginx && \
    rm -rf /var/lib/apt/lists/* && \
    apt clean && \
    rm /etc/nginx/nginx.conf
COPY MyProject/docker/nginx.conf /etc/nginx/nginx.conf

WORKDIR /app
ENV ASPNETCORE_URLS http://+:4000
EXPOSE 4000 80

As you can see I'm installing NGINX in my dockerfile and exposing 4000 and 80 port numbers. In the nginx.conf file NGINX listens for port 80 and pass requests to 4000 which is the port my .NET Core application listens.
