Before we dive deeper into how to deploy your application on Google Cloud Platform, let's take a quick look at what Google Cloud Platform (GCP) is.

What is Google Cloud Platform?

Google Cloud Platform is a suite of cloud computing services provided by Google. It offers a wide range of infrastructure, platform, and software services to help you build, manage, and scale your applications on a global scale.

Some of the popular services that come under Google Cloud Platform are:

• Compute Engine
• App Engine
• Kubernetes Engine
• Cloud Storage
• BigQuery
• Cloud SQL
• Cloud Pub/Sub
• Cloud Functions

Each service offers unique features and capabilities to help you manage your application effectively.

Getting started with Google Cloud Platform

To get started with Google Cloud Platform, you need a Google Cloud account. If you don't have one, you can create one for free. Once you have your account, you can go to the Google Cloud Console, where you can create and manage your projects, resources, and services.

Creating a Project

The first step is to create a project.

1. Go to the Google Cloud Console
2. Click on the project drop-down menu
3. Click on the "New Project" button
4. Enter a name for your project
5. Click on the "Create" button

Once you have created your project, you can select it from the project drop-down menu, and you will be redirected to your project dashboard.

Creating a Billing account

To use Google Cloud Platform, you will need to create a billing account. You can do this by following these simple steps:

1. Go to the Google Cloud Console
2. Click on the project drop-down menu
3. Click on "Billing"
4. Click on "Link a billing account"
5. Follow the prompts to create a new billing account or link an existing billing account

Once you have created your billing account, you can start using Google Cloud Platform.

Deploying your application on Google Cloud Platform

Now that we have our Google Cloud account set up let's dive into the exciting part of deploying an application on Google Cloud Platform.

Here's the process of deploying your application on Google Cloud Platform:

1. Choosing a deployment strategy

Before we deploy our application, we need to decide on a deployment strategy that suits our application's needs.

There are several deployment strategies such as:

• Manual Deployment
• Continuous Deployment
• Blue-Green Deployment
• Rolling Deployment

Each strategy has its pros and cons, based on the requirements of your application choose a deployment strategy that suits your application.

2. Configuring your application

The next step is to configure your application for deployment on Google Cloud Platform.

Here's what you need to do:

Create a Dockerfile

A Dockerfile is a text file that contains instructions for building and deploying a Docker image. It's an essential file that you need to create to deploy your application on Google Cloud Platform.

Here's an example of a basic Dockerfile:

# Use an official Python runtime as a parent image
FROM python:3.8-slim-buster

# Set the working directory to /app
WORKDIR /app

# Copy the current directory contents into /app
COPY . /app

# Install any needed packages specified in requirements.txt
RUN pip install --trusted-host pypi.python.org -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"]

This Dockerfile installs Python and its dependencies and sets up the command to run when the container launches. Make sure that the Dockerfile contains all the necessary configurations for your application.

Create a YAML file for Kubernetes deployment

If you're deploying your application on Kubernetes, you need to create a YAML file that describes how to deploy and scale your application.

Here's an example YAML file that deploys a Docker image to a Kubernetes Pod:

apiVersion: v1
kind: Pod
metadata:
  name: myapp
spec:
  containers:
  - name: myapp
    image: gcr.io/[PROJECT_ID]/my-docker-image
    ports:
    - containerPort: 80

This YAML file sets up a Pod that runs a Docker container with the specified image.

Create a docker-compose.yml file

If you're deploying your application using Docker Compose, you need to create a docker-compose.yml file that describes how to launch and run your application.

Here's an example of a simple docker-compose.yml file:

version: '3'
services:
  web:
    build: .
    ports:
      - "5000:5000"
  redis:
    image: "redis:alpine"

This docker-compose.yml file sets up two services: a web service that builds the Docker image and exposes it on port 5000, and a Redis service using an existing Redis Docker image.

3. Building the Docker image

Once you have configured your application, the next step is to build the Docker image. The Docker image is a packaged version of your application that contains all the necessary dependencies and configurations needed to run your application.

To build your Docker image, open the command line and navigate to the directory that contains your Dockerfile.

Here's the command to build your Docker image:

docker build -t [IMAGE_NAME]:[TAG] .

Replace [IMAGE_NAME] with the name that you want to give to your Docker image and [TAG] with the version of your application.

Once the Docker image is built, you can use it to run your application on Google Cloud Platform.

4. Pushing the Docker image to Google Container Registry

Once you have built your Docker image, you need to push it to Google Container Registry (GCR), a storage solution for your Docker images.

Here's the command to push your Docker image to GCR:

docker push gcr.io/[PROJECT_ID]/[IMAGE_NAME]:[TAG]

Replace [PROJECT_ID] with your Google Cloud project ID, [IMAGE_NAME] with the name of your Docker image, and [TAG] with the version of your application.

5. Deploying your application

Now that you have your Docker image in GCR, you can deploy your application using Google Cloud Platform.
