Getting Started: IBM Code Engine Tutorial

In the fast-evolving landscape of cloud computing, IBM Cloud Code Engine emerges as a transformative force, providing a fully managed, serverless platform for a diverse range of containerized workloads. From web applications to microservices, event-driven functions, and batch jobs, Code Engine simplifies the deployment process by automatically building container images from your source code. The seamless integration within the Kubernetes infrastructure ensures that all workloads function harmoniously. This analysis will delve into key terms, deployment options, and practical steps to harness the potential of IBM Cloud Code Engine.

Key Terms: Understanding the Foundation:

Before delving into deployment strategies, let’s familiarize ourselves with key terms that form the foundation of Code Engine.

  • Project: A project serves as a vital organizational unit, grouping Code Engine entities such as applications, jobs, and builds. It streamlines resource management and grants access to its associated entities.
  • Application: An application, or app, executes your code to handle HTTP requests. The auto-scaling feature adjusts the number of running instances based on incoming workloads, ensuring optimal performance.
  • Build: The build process creates container images from your source code. Code Engine supports building from a Dockerfile or Cloud Native Buildpacks, providing flexibility in image creation.
  • Function: A Function represents a stateless code snippet designed to execute tasks in response to an HTTP request, offering a lightweight and efficient approach to handling specific functionalities.
  • Job: Unlike applications, jobs are intended to run one time and exit. They execute one or more instances of your executable code, making them suitable for tasks that don’t require continuous server presence.

Deployment Options: From Apps to Functions:

1. Deploying Your First Code Engine App:

Creating and deploying a Code Engine application is a straightforward process:a. Open the Code Engine console.

b. Select or create a project.

c. Choose “Application” and provide a unique name.

d. Specify the container image (e.g., icr.io/codeengine/helloworld).

e. Click “Create” and, once the application is ready, test it using the provided URL.

Sample: 

# 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 to the working directory
COPY package*.json ./

# Install app dependencies
RUN npm install

# Copy the application files to the working directory
COPY . .

# Expose the port on which the app runs
EXPOSE 3000

# Define the command to run your application
CMD [“node”, “app.js”]

2. Running Your First Code Engine Job:

Executing a Code Engine job involves the following steps:

a. Open the Code Engine console.

b. Select or create a project.

c. Choose “Job” and provide a unique name.

d. Specify the container image (e.g., icr.io/codeengine/helloworld).

e. Click “Create” and then submit the job with default values.

Sample:

# Use an official lightweight Alpine image
FROM alpine:3.14

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

# Copy the script to the working directory
COPY myscript.sh .

# Set the script as executable
RUN chmod +x myscript.sh

# Define the command to run your script
CMD [“./myscript.sh”]

3. Running Your First Function:

Developing and running a Code Engine function includes these steps:

a. Open the Code Engine console.

b. Select or create a project.

c. Choose “Function” and provide a unique name.

d. Select the runtime environment (e.g., Node.js 18).

e. Click “Create” and test the function using the provided URL.

4. Building Your First Container Image:

Creating and deploying a container image involves:

a. Open the Code Engine console.

b. Select or create a project.

c. Choose “Application” and provide a unique name.

d. Specify the container image reference (e.g., icr.io/codeengine/helloworld).
