I'm trying to set up my dotnet core app to run through docker on my mac. My Dockerfile looks like this:
FROM microsoft/dotnet:sdk AS build-env
WORKDIR /app
# copy csproj and restore as distinct layers
COPY *.csproj ./
RUN dotnet restore
# copy everything else and build
COPY . ./
RUN dotnet publish -c Release -o out
# build runtime image
FROM microsoft/dotnet:runtime
WORKDIR /app
COPY --from=build-env /app/out ./
ENTRYPOINT ["dotnet", "backend.dll"]
When I run: docker build -t backend .
I get :
Sending build context to Docker daemon 1.133MB
Step 1/10 : FROM microsoft/dotnet:sdk AS build-env

Step 4/10 : RUN dotnet restore
---> Running in 46f3843faad7
Aborted
The command '/bin/sh -c dotnet restore' returned a non-zero code: 134
I did some debugging and noticed when I ran any command of dotnet it bombs. I ran dotnet --info and it showed the information but also Aborted. Any suggestions would be greatly appreciated.

I have a VS 2019 Solution with 2 projects: P1 (Standard lib) & P2 (ASP.NET Core exe).
P2 contains a Dockerfile.
I have copied the Docker file to up folder, tried to build the docker running the cmd :
>docker build -f Dockerfile ..

I am trying to build a docker image for an ASP.NET Core 3.1 application and I fail to restore the packages. My solution has multiple projects and after copying all the project files, I am trying to create a layer which contains restored dependencies only.

I am running without cache to be able to output all the csproj files within the container for each run (otherwise it gets cached and the files are not longer displayed).
docker build --no-cache -f ExampleApi/Dockerfile .

This is my first time using docker so I am probably doing some things wrong. I am trying to dockerize my asp.net core microservice. I was following this tutorial: https://docs.docker.com/engine/examples/dotnetcore/. There I found this dockerfile:
FROM mcr.microsoft.com/dotnet/core/sdk:2.2 AS build-env
WORKDIR /app
# Copy csproj and restore as distinct layers
COPY FlightManagement.csproj ./
RUN dotnet restore
# Copy everything else and build
COPY . ./
RUN dotnet publish -c Release -o out
# Build runtime image
FROM mcr.microsoft.com/dotnet/core/aspnet:2.2
WORKDIR /app
COPY --from=build-env /app/out .
ENTRYPOINT ["dotnet", "FlightManagement.dll"]
When I try the following command:
docker build -t flightmanagement .
I get the following output:

I tried multiple tutorials on dockerizing an asp.net core application but they al seem to give the same error. I hope someone is ably to help me.
Thanks.
For mcr.microsoft.com/dotnet/core/sdk:2.2, it default .net core sdk is 2.2.300.
But, you create a project with specifying the sdk is 2.2.106 by global.json.
Change your global.json like below:
{
"sdk": {
"version": "2.2.300"
}
}
I have a vanilla .NET Core 2 web app that I setup in JetBrains Rider and I immediately started working on a Docker environment for it. I followed this guide to get started:
https://docs.docker.com/engine/examples/dotnetcore/
I altered it slightly to come up with this:
FROM microsoft/dotnet:latest AS packager
RUN mkdir -p /opt/build
WORKDIR /opt/build
# Copy csproj and restore as distinct layers
COPY *.csproj .
RUN dotnet restore
# Copy everything else and build
COPY . .
RUN dotnet publish -c Release -o bin
# --
# Build runtime image
FROM microsoft/dotnet:runtime AS runtime
RUN mkdir -p /opt/app
WORKDIR /opt/app
COPY --from=packager /opt/build/bin/. .
ENTRYPOINT ["dotnet", "/opt/app/aspnetapp.dll"]
The image builds and when I go to run the container I get the following output:
dan#mycomputer ~/Desktop/coreapi (master)
$ docker build -t myapp .

The app doesn't run and I get a message that says I need to install the SDK. What's up with that? Shouldn't the runtime Docker image have everything neede to run the app?
I was able to find the solution by modifying the ENTRYPOINT to run tail -f /dev/null. From there, I entered the container and saw that the name of the binary adjusts based on your project name which the Docker documentation didn't make clear to me.
I also updated my base images and this solved my problem. Here is my latest Dockerfile below:
FROM microsoft/dotnet:2.1-sdk AS packager
RUN mkdir -p /opt/build
WORKDIR /opt/build
# Copy csproj and restore as distinct layers
COPY *.csproj .
RUN dotnet restore
# Copy everything else and build

you're using microsoft/dotnet:2.1-aspnetcore-runtime instead microsoft/dotnet:2.1-sdk. change the base image.
