DevOpsProjectWithGCP

In this project, you will build a continuous integration pipeline using Cloud Source Repositories, Cloud Build, build triggers, and Container Registry.

Prerequisites

Google Cloud tools Cloud Source Repositories.
Cloud Build.
Build triggers.
Container Registry.

And, a bit of familiarity with GCP.

Objectives - In this lab, you will learn how to perform the following tasks:

Create a Git repository
Create a simple Python application
Test Your web application in Cloud Shell
Define a Docker build
Manage Docker images with Cloud Build and Container Registry
Automate builds with triggers
Test your build changes
You have done a great job! Pat ya back!

Task 1 : Create a Repository

After creating this repo -> got Cloud Console -> Activate Cloud shell

mkdir gcp-course                                     #creating the folder
ls
cd gcp-course
gcloud repos clone DevOps-repo                      #cloning the repo in our folder

Task 2: Create a Simple python application

open the editor on gcp -> click on new window -> select the folder or file of you repo

main.py


from flask import Flask, render_template, request
app = Flask(__name__)
@app.route("/")
def main():
    model = {"title": "Hello! Welcome to the GCP DevOps Project!!"}
    return render_template('index.html', model=model)
if __name__ == "__main__":
    app.run(host='0.0.0.0', port=8080, debug=True, threaded=True)

Save this file cntrl+S

Create a new folder in the gcp-course/DevOps-repo folder "templetes"

Afte that -

Create a new file "layout.html" inside the templetes folder

paste the htm code here -

<!doctype html>
<html lang="en">
<head>
    <title>{{model.title}}</title>
    <!-- Bootstrap CSS -->
    <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css">
</head>
<body>
    <div class="container">
        {% block content %}{% endblock %}
        <footer></footer>
    </div>
</body>
</html>

Create a index.html file in the tempplete folder

{% extends "layout.html" %}
{% block content %}
<div class="jumbotron">
    <div class="container">
        <h1>{{model.title}}</h1>
    </div>
</div>
{% endblock %}

Create a requriements.txt in the templete folder

Flask==2.0.3

goto on the Cloud shell

git config --global user.name "Your Name"
git config --global user.email "your@email.com"
git status

git add --all
git status
git commit -a -m "Message"
git push origin master

Task 3. Define a Docker build

Create a dockerfile in templete folder and push it on th repo

Dockerfile-

FROM python:3.7
WORKDIR /app
COPY . .
RUN pip install gunicorn
RUN pip install -r requirements.txt
ENV PORT=80
CMD exec gunicorn --bind :$PORT --workers 1 --threads 8 main:app

git add --all
git status
git commit -a -m "Message"
git push origin master

Task 4. Manage Docker images with Cloud Build and Container Registry

For checking the project id Commands-

 echo $DEVSHELL_PROJECT_ID

So now , For building the docker file -> goto the templete folder , where your docker file is present

gcloud builds submit --tag gcr.io/$DEVSHELL_PROJECT_ID/devops-image:v0.

IMAGE CREATE

Container Ragistry - images

Create a Trigger -

Cloud Build -

for building the code crreate an virtusl machine - Compute Engine & allow the HTTP traffic

pushing all the files on the repo -

Task 5. Automate builds with triggers

Create a Trigger -

Cloud Build -> Trigger -> Create Trigger -> Follow Below images
