Dear programmers, happy year of monkey. I believe many Yuan/ape are attracted by titles. I will explain the title first.

Prompt

This article is a semi-Popular Science article that does not go deep into technical details.

Title explanation ASP. NET Core 1.0 labels ¶

ASP. NET Core 1.0 isCross-platformAndOpen SourceIs used to develop the website/Web API framework, formerly known as ASP. NET 5 (also known as ASP. NET vNext), but not ASP.. NET 4.6 Is an upgraded version from scratch.

ASP. NET Core 1.0 splits all functions and modules and completely decouples them. The source code can be found on Github ASP. NET.

Container ¶

Container technology is a virtualization technology. Unlike virtual machines, container technology does not provide an entire operating system. It can only provide an isolated running environment; container technology consumes much less system resources than virtual machines.

Docker is an open-source application container engine that does not need to change the kernel. It mainly uses the kernel features of the operating system to achieve virtualization, and all containers run in the same kernel.

Annotation

All containers run in the same kernel, which means that all containers must match the Operating System. Windows containers cannot run on Linux directly.

Monkey tips ¶

MonkeyIs a Spanish wordmonoIn Spanish, this word also has a cute meaning.

What I want to express is the Mono Project.

Therefore, this article means: in 2016, create a Docker container containing the Mono runtime environment, and then start two instances so that they can run ASP. NET Core 1.0 programs for you.

Create a home for the monkey ¶

First, you need to install the running environment of Docker (Linux), which is the blue part in the figure.

Prompt

Docker is not only for Linux, but also for Windows (which is currently a preview). That is to say, you can install the following two images.

However, if Windows is used, the complete. NET Framework is generally used insteadmono.

Create Dockerfile

If you useyo aspnetYou already have the Dockerfile. Otherwise, you need to create a file named Dockerfile in the project directory.

FROM microsoft/aspnet:1.0.0-rc1-update1COPY . /appWORKDIR /appRUN ["dnu", "restore"]EXPOSE 5000/tcpENTRYPOINT ["dnx", "-p", "project.json", "web"]

Explain each line.

 
 

  
  
Since the Docker file system is layered, FROM indicates the basis of the current image, followed by a colon;
  
  
COPY Copies local files to Docker,.Indicates the current directory;
  
  
WORKDIR specifies the working directory;
  
  
RUN indicates to RUN a program, followed by parameters;
  
  
EXPOSE indicates exposing a port number of Docker so that the host can communicate with the container;
  
  
ENTRYPOINT specifies the entry point. The first entry is the program, followed by the parameter.
 
 

• Build a project

docker build .

View the built IMAGE. The image id is the identifier of the built IMAGE.

docker images

Name the image

docker tag {IMAGE ID} qinnz/wukong

Tips

An image is equivalent to a container negative. We can use an image to create many identical containers.

Let us run ASP. NET Core program at the same time ¶

Now that you have an image, you need to run it. Of course, you can run multiple instances (but you cannot bind the same port ).

docker run --name monkey_king -d -p 80:5000 qinnz/wukongdocker run --name his_dobule -d -p 81:5000 {IMAGE ID}

We are at the background (-dTwo instances are started (one is the real Monkey King and the other is the fake Monkey King), respectively. These two containers can be identified by Tag or image id) port 5000 of is mapped to port 80 and port 81 of the host machine.

So far, we have created a Docker container that contains the Mono runtime environment and asked it to run the ASP. NET Core 1.0 program for you.
