# GCP DevOps - HandsOn | Cloud Build , Cloud Build Trigger , Container Registry |
In this lab, you built a continuous integration pipeline using the Google Cloud tools Cloud Source Repositories, Cloud Build, build triggers, and Container Registry.
**Cloud Source Repositories , Cloud Build, Cloud Build Trigger , Container Registry ,**
## DevOpsProjectWithGCP
In this project, you will build a continuous integration pipeline using Cloud Source Repositories, Cloud Build, build triggers, and Container Registry.
### **Prerequisites**
1. Google Cloud tools Cloud Source Repositories.
2. Cloud Build.
3. Build triggers.
4. Container Registry.
And, a bit of familiarity with GCP.
### **Objectives - In this lab, you will learn how to perform the following tasks:**
1. Create a Git repository
2. Create a simple Python application
3. Test Your web application in Cloud Shell
4. Define a Docker build
5. Manage Docker images with Cloud Build and Container Registry
6. Automate builds with triggers
7. Test your build changes
8. 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 -
```
{{model.title}}
{% block content %}{% endblock %}
```
### Create a index.html file in the tempplete folder
```
{% extends "layout.html" %}
{% block content %}
{{model.title}}
{% 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
