Working with Codes

This tutorial talks about how to work inside container

Update Docker Compose for dev need
Entering dev container using docker compose
Create source codes in dev container
Installing dependencies
- C# nuget
- Golang go get
- Nodejs npm install
- Python pip install
Compile and Run code

Benefit of dev with docker: decouple machine from dev environment, make host clean, and dev everywhere

Docker compose file is basically script version of docker run

Create C# website and run webapp

Adding following to services:

    working_dir: /work
    entrypoint: /bin/sh
    stdin_open: true
    tty: true
    volumes: 
      - ./c#/src/:/work
    ports:
      - 5000:5000

where:

working_dir set working directory in container
volumes set for mounting volume, which we directly mount source code into container working directory
5000:5000, 1st one is the port on host, 2nd one is the exposed port in container

docker-compose csharp, where csharp is the service name defined in docker-compose file
docker-compose run -d csharp to start container
In VScode, select the running container and click Attach Visual Studio Code, otherwise the normal vscode don't have privilege to run it later

In new created attached VSCode window dotnet new webapp to create .NET app source code, these source code are all root based
Modify the source code by adding .UseUrl("http://*:5000") to create a simple website in Program.cs
Build the webapp by dotnet build in attached VSCode
Run webapp by dotnet run in attached VSCode, we can now view the web in host via localhost:5000
