This page provides an overview of how to integrate Docker with Alibaba Cloud Server Less Service (SLS). Docker integration allows you to containerize your applications and deploy them on SLS, making it easier to manage and scale your applications.

Prerequisites

Quick Start

  1. Create a Dockerfile: Define your application's environment and dependencies in a Dockerfile.
  2. Build and Push Docker Image: Build your Docker image and push it to a container registry.
  3. Deploy to SLS: Use the SLS console or SDK to deploy your Docker image to an SLS instance.

Step-by-Step Guide

1. Create a Dockerfile

Create a Dockerfile in the root directory of your application. Here's an example:

# Use an official Python runtime as a parent image
FROM python:3.7-slim

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

# Copy the current directory contents into the container at /usr/src/app
COPY . .

# Install any needed packages specified in requirements.txt
RUN pip install --no-cache-dir -r requirements.txt

# Make port 80 available to the world outside this container
EXPOSE 80

# Define environment variable
ENV NAME World

# Run app.py when the container launches
CMD ["python", "app.py"]

2. Build and Push Docker Image

Build the Docker image using the following command:

docker build -t my-app .

Push the image to a container registry:

docker push my-app:latest

3. Deploy to SLS

Use the SLS console or SDK to deploy your Docker image to an SLS instance.

Using the SLS Console:

  1. Log in to the SLS console.
  2. Create a new application or select an existing one.
  3. Click on "Deploy" and choose "Docker Image".
  4. Enter the image URL and configure other settings as needed.
  5. Click "Deploy" to start the deployment process.

Using the SLS SDK:

from sls import SLSClient

# Initialize SLS client
client = SLSClient(access_key_id='your_access_key_id', access_key_secret='your_access_key_secret', endpoint='your_endpoint')

# Deploy Docker image
response = client.deploy_docker_image(image_url='my-app:latest', region='your_region', namespace='your_namespace', app_name='your_app_name')
print(response)
