DevDock

DevDock is a VS Code extension for managing Docker-based development environments.

Features

• Create and manage Docker containers for development.
• Simplified workflows for building, running, and debugging code in isolated environments.

Installation

1. Download the extension from the VS Code Marketplace.
2. Install using the Extensions view in Visual Studio Code.

Usages

How to Use the VSCode Extension

1. Create an Empty Directory and Open It in VSCode

   • Start by creating a new empty directory.
   • Open the directory in VSCode.

2. Create a File with Your Desired Programming Language Extension

   • Example: main.py for Python.

3. Select the File in the Sidebar and Run devdock.run

   • Use the shortcut: Cmd (Ctrl) + Shift + Alt + R.

4. A {language}.Dockerfile is Automatically Generated

   • For Python, this would be python.Dockerfile:

     FROM python:3.12-alpine
     
     COPY . /app
     COPY requirements.txt /app
     
     WORKDIR /app
     
     RUN pip install --no-cache-dir -r requirements.txt
     
     EXPOSE 8080 80
     EXPOSE 443
     
     VOLUME /data
     VOLUME /data /tmp  # The second "/data" will be ignored as it's duplicated
     VOLUME [ "/data" ] # This "/data" will also be ignored due to duplication
     VOLUME [ "/data", "/tmp2" ] # Only "/tmp2" is added as "/data" is redundant
     
     CMD ["python3", "main.py"]
     

5. Modify the Generated Files as Needed for Your Development Environment

   • When using the EXPOSE keyword, ports will be automatically mapped to random ports during execution:

     -p 8080:{random_port} -p 80:{random_port} -p 443:{random_port}
     

   • When using the VOLUME keyword, a python.Dockerfile.mount.json file is generated to define host-directory mappings.

   • Example python.Dockerfile.mount.json:

     {
        "volumes": {
        	"/host/path": "/container/path",
        	"/data": "/app/data",
        	"/tmp": "/app/tmp",
        	"/tmp2": "/app/tmp2"
        }
     }
     

6. Check Container Logs with devdock.logs

   • Use this command to view the output inside the running container.

7. Open the Configuration File with devdock.openConfig

   • This command opens the configuration file, where you can:
     • Edit the default Dockerfile template.
     • Add support for additional programming languages.
     • Even if the extension is uninstalled, this configuration file remains.
     • When updating the extension, existing configurations take precedence and are merged with the latest version.
     • If you want to remove it, you must manually delete the configuration file from its directory.
