How to develop using devcontainers in VSCode

You can develop using the vscode remote containers extension. In this approach you need to:

  • Install the extension in your vscode: ms-vscode-remote.remote-containers

  • On your command pallet, select: “Remote-Containers: Reopen in Container”

  • If it’s the first time, vscode will take care of building the images. This might take some time.

  • Then a new vscode window will open, and it’ll be connected to your docker container.

  • The message “Dev Container: Debug Docker Compose” will appear in the bottom-left corner of that window.

  • In the vscode terminal, you’re going to see something similar to root@77e80acc89b8:/usr/src/geonode#.

  • To run your application, you can use the integrated terminal (./manage.py runserver 0.0.0.0:8000) or the vscode “Run and Debug” option. For launching with “Run and Debug”, generate the following files in the .vscode folder inside the .devcontainer folder

launch.json

{
    "version": "0.2.0",
    "configurations": [
        
        {
            "name": "Python Debugger: Django",
            "type": "debugpy",
            "request": "launch",
            "args": [
                "runserver",
                "0.0.0.0:8000"
            ],
            "django": true,
            "autoStartBrowser": false,
            "justMyCode": false,
            "program": "/usr/src/geonode/manage.py"
        }
    ]
}

The .devcontainer folder should look like this

.devcontainer
├── .env
├── .vscode
│   └── launch.json
├── devcontainer.json
├── docker-compose.yml
