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 $DEVSHELL_PROJECT_IDSo now , For building the docker file -> goto the templete folder , where your docker file is present
gcloud builds submit --tag gcr.io/$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
