Pushing your asp.net core application to under docker

Step1 create dotnet core application as structure below by name Myapp2

step 2 Now create the docker file under the project without any  extension and also create the .dockerignore file 

step 3  now our project working directory would be like the below ,where we put docker file and .dockerignore file

step 4 now under the dockerfile write the below code so that required things install  in docker container

FROM mcr.microsoft.com/dotnet/core/sdk:3.1 AS build

WORKDIR /Myapp2

# copy csproj and restore as distinct layers

COPY *.sln .

COPY Myapp2/*.csproj ./Myapp2/

RUN dotnet restore

# copy everything else and build app

COPY Myapp2/. ./Myapp2/

RUN dotnet publish -c Release -o out

FROM mcr.microsoft.com/dotnet/core/aspnet:3.1 AS runtime

WORKDIR /Myapp2/Myapp2

COPY --from=build /Myapp2/out ./

ENTRYPOINT ["dotnet", "Myapp2.dll"]

step 5 now use the .dockerignore file mentioned the below code under it so that those folders get ignore 

# directories

**/bin/

**/obj/

step 6 now come to the working directory Myapp2 on cmd  and run the build command 

docker build -t myapp2:v1 .

now you can see our docker build command success and image has created 

step 7 Now create the container by using the below command as per our application

docker run -d -p 8080:80 --name mycoreconatiner myaap2:v2

step 8 use this command to find the ip of running container means ip address ,

docker inspect mycoreconatiner

now you can see our application running on the below ip address

now do the request of this url(http://172.27.59.53/weatherforecast) on browser then our application will run as below
