15-Docker-Flask-Template
Adding Render Template to Flask App
Templates are files that display static and dynamic content to users who visit your application.
#So, first let's create home.html
sudo nano app/templates/home.html
#which contains
<!doctype html>
<html lang="en-us">
<head>
<meta charset="utf-8">
<meta http-equiv="x-ua-compatible" content="ie=edge">
<title>Welcome home</title>
</head>
<body>
<h1>Home Page</h1>
<p>This is the home page of our application.</p>
</body>
</html>
#Next, modify app/views.py file so that users are served the contents of the home.html file whenever they visit the /template route on your application.
sudo nano app/views.py
#which contains
from flask import render_template
from app import app
@app.route('/')
def home():
return "Hello world!"
@app.route('/template')
def template():
return render_template('home.html')
#As we created a new project in our local directory and named it
15-Docker-Flask-Template
#then we have to change our PATH in
Dockerfile
#wich will contain
FROM tiangolo/uwsgi-nginx-flask:python3.8-alpine
RUN apk --update add bash nano
ENV STATIC_URL /static
ENV STATIC_PATH /home/vit/Desktop/15-Docker-Flask-Template/app/static
COPY ./requirements.txt /home/vit/Desktop/15-Docker-Flask-Template/requirements.txt
RUN pip install -r /home/vit/Desktop/15-Docker-Flask-Template/requirements.txt
#as well as we need to change the name of our app to "docker.test15"
start.sh
#which contains
#!/bin/bash
app="docker.test15"
docker build -t ${app} .
docker run -d -p 56733:80 \
--name=${app} \
-v $PWD:/app ${app}
#and finally, to create and start new container "docker.test15"
cd 15-Docker-Flask-Template
sudo bash start.sh
#to verify that docker is running
sudo docker ps
#if nor running, start it
sudo docker start docker.test15
#To verify visit browser page
localhost:56733/template
#If we were developed our app withing the same local directory, we would have just stop and restart the Docker containers
sudo docker stop docker.test15 && sudo docker start docker.test15
