This is some sample code to create a dotnet core web app, install nginx, configure nginx as a reverse proxy and provide a warmup script so the container is not added to the Azure web app load balancer until the application is warmed up. This application will not have a long warm up since it is just a sample. To understand Azure and site warm-ups please read reference this: https://github.com/AdamPaternostro/Azure-Tomcat-Web-App-Container
Software: Install Docker
Software: Install .NET Core 2.1.5
Create directory: mkdir azure-web-app-nginx-reverse-proxy-dotnet-core-linux
Change directory: cd azure-web-app-nginx-reverse-proxy-dotnet-core-linux
Create directory: mkdir nginxproxy
Change directory: cd nginxproxy
Create .NET code: dotnet new mvc
Restore Packages: dotnet restore
Change file: Add .UseUrls("http://*:5000/") to the Program.cs
WebHost.CreateDefaultBuilder(args)
.UseUrls("http://*:5000/")
.UseStartup<Startup>();
Build: dotnet build
Run locally: dotnet run
Open a browser and view: http://localhost:5000/
Ctrl+C to quit the dotnet run
Publish locally: dotnet publish
Change directory: cd ..
Download Files: By hand or wget these 3 files (Dockerfile, start-server.sh, azurewebsites.net)
wget https://raw.githubusercontent.com/AdamPaternostro/azure-web-app-nginx-reverse-proxy-dotnet-core-linux/master/Dockerfile
wget https://raw.githubusercontent.com/AdamPaternostro/azure-web-app-nginx-reverse-proxy-dotnet-core-linux/master/start-server.sh
wget https://raw.githubusercontent.com/AdamPaternostro/azure-web-app-nginx-reverse-proxy-dotnet-core-linux/master/azurewebsites.net
Build Image: docker build -t nginxreverseproxydotnetcorelinux .
Run Image Locally: docker run --rm -it -p 80:80 nginxreverseproxydotnetcorelinux
Edit Hosts file: When you go to localhost you will see nginx default page
Mac: /private/etc/hosts
Windows: C:\windows\system32\drivers\etc\hosts
ADD: 127.0.0.1 docker.azurewebsites.net
Now load docker.azurewebsites.net and you should see your app
Ctrl+C to stop
Clean Up Docker: docker stop $(docker ps -aq) | docker rm $(docker ps -aq)
Upload to Azure ACR:
Login Registry: docker login REMOVED.azurecr.io --username REMOVED --password <<REMOVED>>
Tag: docker tag nginxreverseproxydotnetcorelinux:latest REMOVED.azurecr.io/nginxreverseproxydotnetcorelinux:latest
Push: docker push REMOVED.azurecr.io/nginxreverseproxydotnetcorelinux:latest
In the file nginxproxy.csproj make sure your Target Framework is 2.1
<PropertyGroup>
<TargetFramework>netcoreapp2.1</TargetFramework>
</PropertyGroup>
In the program.cs make sure you have the UseUrls line:
WebHost.CreateDefaultBuilder(args)
.UseStartup<Startup>()
.UseUrls("http://*:5000/")
.Build();
Since your application name will be different you will mostlikely need to change:
- You will need to change line 4 in start-server.sh
- You will need to change line 10 in start-server.sh
- Publish release mode: (dotnet publish --configuration Release)
- You will probably build in Release mode so you will need to change line 83 in the Dockerfile
