Build And Deploy ASP.NET Core WebAPI Using Docker

15. Enable rh-dotnet21 so that we can run dotnet from bash . "scl enable rh-dotnet21 bash".

16. Check if dotnet is installed properly or not. Run the command "dotnet --version". If dotnet is successfully installed you will get the version number.

17. Make a folder called services and clone your repository inside it. ( command : "mkdir Services" )
    
    
    

18. Once your repository is cloned, build your project using the command: "dotnet build". Make sure you are in the solution folder.
    
    In my case, the project name is DockerDemo.
    
    
    
    
    
    

19. In this path, create a Dockerfile using the command: "vi Dockerfile".
    
    Copy and paste the below code in this Dockerfile.
    
    1. FROM microsoft / dotnet: 2.1 - sdk
    2. WORKDIR / app
    3. # Copy csproj and restore as distinct layers
    4. COPY.. / RUN dotnet restore
    5. # Copy everything else and build
    6. COPY.. /
    7. #WORKDIR / app / DockerDemo
    8. RUN dotnet publish - c Release - o out
    9. WORKDIR / app / ToDoWebApi / out
    10. ENTRYPOINT["dotnet", "ToDoWebApi.dll"]

20. Next, we need to execute following commands to setup our Docker.

Installing Docker using command	yum install docker
Start Docker service so we can use it	service docker start

• Once we have installed docker, let's use Docker to build our project.
  
  Command: "docker build -t dockerdemo."
  
  If your project is successfully built, docker will create an image for it.

21. Now, let's run our image using the command: docker run -d -p 8080:80 --name myapp dockerdemo.
    
    Here we are saying docker that run our dockerdemo image at port 8080 with container name myapp.
    
    
    

22. If you want to see all the running containers, "docker ps",
    
    "docker ps -a" will show you all the container which ran earlier.

23. So now your WebApi is UP and Running. Let check whether APIs are working as expected or not. Type "curl <port>/api/values". In my case, "curl 0.0.0.0:8080/api/values"
    
    
    

This is too much manual work, in the next blog, we will try to automate things.
