In the development environment for helixml/aispec, Docker is utilized to ensure a consistent and reproducible setup. This is a detailed guide addressing the Docker configuration specific to the development phase.

Prerequisites

Ensure that Docker is installed on your system. Verify the installation with:

docker --version

Dockerfile Setup

The Dockerfile is essential for building your development environment. Below is an example of a simple Dockerfile you might use:

# Use an official Node.js runtime as a parent image
FROM node:14

# Set the working directory in the container
WORKDIR /usr/src/app

# Copy package.json and package-lock.json
COPY package*.json ./

# Install dependencies
RUN npm install

# Copy the rest of your application
COPY . .

# Expose the desired port
EXPOSE 3000

# Run the application
CMD [ "npm", "start" ]

This example uses Node.js as a base. Modify the base image according to the specific requirements of your project, if necessary.

Building the Docker Image

Once the Dockerfile is in place, build the Docker image with the following command:

docker build -t aispec-dev .

This command tags the built image as aispec-dev.

Running the Docker Container

After building the image, you can run the container with the command:

docker run -it -p 3000:3000 --name aispec-dev-container aispec-dev

• -it allows you to interact with the container’s shell.
• -p 3000:3000 maps port 3000 of the host to port 3000 of the container.
• --name aispec-dev-container names your running container for easier reference.

Volume Mounting for Development

To enable live reloading and facilitate easier development, mount your project directory into the container:

docker run -it -p 3000:3000 -v $(pwd):/usr/src/app --name aispec-dev-container aispec-dev

The -v $(pwd):/usr/src/app option mounts the current directory to /usr/src/app in the container, ensuring that any code changes are reflected immediately.

Docker Compose Configuration

For more complex environments, consider using Docker Compose. Here’s an example docker-compose.yml configuration:

version: '3'

services:
  aispec:
    build:
      context: .
      dockerfile: Dockerfile
    ports:
      - "3000:3000"
    volumes:
      - .:/usr/src/app
    environment:
      - NODE_ENV=development

With this docker-compose.yml, you can start your development environment with:

docker-compose up

Stopping the Container

Once development is complete, you can stop the running container using:

docker stop aispec-dev-container

If using Docker Compose, stop the services with:

docker-compose down

Conclusion

This comprehensive Docker configuration ensures that the development environment for helixml/aispec is optimized for productivity and ease of use. Advanced configurations can be tailored as necessary, but the above steps provide a solid foundation for development.
