aspnet5-dockerfile

Dockerfile which can be used to build fully functional ASP.NET vNext application as a Docker Container.

Usage

1. Put Dockerfile inside of your ASP.NET vNext project where you have Startup.cs and project.json files.
2. Run the command docker build -t yourProjectName .
3. If your project contains dependencies to lots of libraries such as MVC, go get some coffee.
4. To launch the web application execute command docker run -t -d -p [PORT]:5004 yourProjectName
5. You're now live on the specified [PORT].

How to stop the vNext app on linux

1. Execute docker ps and identify your app container id.
2. Execute docker stop [container id]

How to quickly restart vNext app on linux

1. Execute docker ps and identify your app container id.
2. Execute docker restart -t=1 [container id]

Tip

If you want to perform a quick fix inside of the running app, follow the steps:

1. Execute docker ps to see the list of running apps. Identify your app container id.
2. Run docker exec -i -t [container id] /bin/bash
3. You are now in the bash console inside of your container. To exit bash, just exit.
4. Restart the app (see previous paragraph).

Problems with layout and _ViewStart.cshtml ?

I've came accross the problem, where I've finally ran the application, but it has no styling. The issue was the naming of the _ViewStart.cshtml file. Solution?

1. Rename _ViewStart.cshtml from ViewsFolder to _viewstart.cshtml

Command k kestrel not found in the container?

This is another issue which effectively stopped me for a while when I tried to build the app. It was caused by missing command in project.json.

1. Make sure your commands section in project.json looks like this:

"commands": {
        "web": "Microsoft.AspNet.Hosting --server Microsoft.AspNet.Server.WebListener --server.urls http://localhost:5000",
        "gen": "Microsoft.Framework.CodeGeneration",
        "ef":  "EntityFramework.Commands",
        
        /* kestrel command is required when you run app on linux */
        "kestrel": "Microsoft.AspNet.Hosting --server Kestrel --server.urls http://localhost:5004"
        
    },
