. NET Core for Docker

This article describes how to play the. NET core in Docker

First pull the image in the official document

Docker Pull Microsoft/dotnet:latest

And then there's dotnet this runtime, here's a Web project to create a Web-type project

dotnet NEW-T Web

If you do not have a local dotnet runtime, you can Docker run a

Docker run-rm -it-v/home/hello_dotnet/:/home/hello_dotnet/  microsoft/dotnet:latest

The above command means letting Docker runa dotnet:latest image (microsoft/dotnet:latest) and putting the local/home/hello_ The dotnet volume path is mounted under the container's/home/hello_dotnet (-v/home/hello_dotnet/:/home/hello_dotnet/) and then provides interactive mode for the input output (-it ) automatically delete containers after exiting (--rm)

And then into the container to generate something like this

 [[Email protected]172 -16 - Span style= "color: #800080;" >0 -rm -it-v /home/hello_dotnet/:/home/hello_dotnet/microsoft/dotnet:latest[email  Protected]: /# cd/home/hello_dotnet/[email protected]: /home/ hello_dotnet# dotnet New-t webcreated new C # project  in /home/hello_dotnet.[ Email protected]: /home/hello_dotnet# ls  controllers Data Models Program.cs readme.md Services Startup.cs views APPSETTINGS.J Son Bower.json gulpfile.js package.json project.json Web. config wwwroot[email protected]: /home/hello_dot net# 

Then update the next package dependency

dotnet Restore

Run directly

Dotnet Run

Modify the default listening port by default localhost:5000 is not good proxy, modify it to 0.0.0.0

usingSystem;usingSystem.Collections.Generic;usingSystem.IO;usingSystem.Linq;usingSystem.Threading.Tasks;usingMicrosoft.AspNetCore.Hosting;namespacewebapplication{ Public classProgram { Public Static voidMain (string[] args) {            varHost =NewWebhostbuilder (). Useurls ("http://0.0.0.0:5000")//Add this line                . Usekestrel (). Usecontentroot (Directory.GetCurrentDirectory ()). Useiisintegration (). Usestartup<Startup>()                .             Build (); Host.        Run (); }    }}

OK, no problem, publish.

[Email protected]:/home/ for. Netcoreapp,version=v1. 0  "npm"

Well, it is not possible to publish a hint to find NPM, NPM This is not node's package dependency tool. After viewing the web that generated this build relies on gulp so it hurts. The default container is only the runtime environment (which may be primarily for thin mirroring) and it needs to install node

You can install node in the container or go to other machines publish

Install NPM

and installing NPM is not enough to install Bower Gulp

No executable found matching command "bower"

No executable found matching command "gulp"

NPM Install Bower-g

NPM Install Gulp-g

OK it's over ...

Project hello_dotnet (. netcoreapp,version=v1.0) was previously compiled. Skipping compilation.

Configuring the following project for use with IIS: '/home/hello_dotnet/bin/debug/netcoreapp1.0/publish '

Publish:published To/home/hello_dotnet/bin/debug/netcoreapp1.0/publish

Exit the container back to the server

The code is already created, so just find a runtime dotnet Hello_dotnet.dll to start the web.

Pack an image, write a dockerfile.

Create a new working directory to organize the structure

OK, everything's fine.

Of course, you can also run in daemon mode.
