# Docker Deployment Commands for FastAPI Backend

## 1. Install Docker on Your GCP VM

sudo apt update


sudo apt install -y docker.io
sudo systemctl start docker
sudo systemctl enable docker
sudo usermod -aG docker $USER
# Log out and log back in, or run:
newgrp docker

## 2. Create a Dockerfile in Your Project Directory

cat > Dockerfile <<EOF


FROM python:3.12-slim

WORKDIR /app

RUN apt-get update && apt-get install -y gcc

COPY requirements.txt .
RUN pip install --upgrade pip && pip install -r requirements.txt

COPY . .

EXPOSE 8000

CMD ["uvicorn", "main:app", "--host", "0.0.0.0", "--port", "8000"]


EOF

## 3. Build the Docker Image

docker build -t workbee-back .

## 4. Run the Docker Container

docker run -d --name workbee-back -p 8000:8000 workbee-back


# App will be available at http://<VM_EXTERNAL_IP>:8000/ or /docs

## 5. (Optional) Use HTTPS with Nginx Reverse Proxy


# Set up Nginx as before, proxying to localhost:8000 (the Docker container).

## 6. (Optional) Push to Google Container Registry (GCR)

# Authenticate Docker to GCR


gcloud auth configure-docker

# Tag your image


docker tag workbee-back gcr.io/<YOUR_PROJECT_ID>/workbee-back:latest

# Push to GCR
docker push gcr.io/<YOUR_PROJECT_ID>/workbee-back:latest

## 7. (Optional) Pull and Run from GCR on Any VM

docker pull gcr.io/<YOUR_PROJECT_ID>/workbee-back:latest


docker run -d --name workbee-back -p 8000:8000 gcr.io/<YOUR_PROJECT_ID>/workbee-
back:latest
## 8. (Optional) Example GitHub Actions Workflow
# If you want a ready-to-use GitHub Actions workflow for CI/CD, just ask!
