How to deploy a Django Docker container to Elastic Beanstalk

realninety5 — Tue, 21 Feb 2023 13:44:28 +0000

You can easily deploy your Django application to Elasticbeastlk (EB) by following these simple steps.

Note, while creating your application, add
Also ensure you have the Elastic Beanstalk cli 'eb' installed on your local machine.

0.0.0.0

to your ALLOWED_HOSTS in your application settings.py, also add this line

import os
live = os.getenv("LIVE")

Add "live" to your ALLOWED_HOSTS too, we will update it with the URL elastic beanstalk will provide us later.

Create a file with the list of requirements for the application to run by running

pip freeze > requirements.txt

Create your Dockerfile


# the base image to run your application
FROM python:3.8.10-slim

# setup environment variable
ENV DockerHOME=/home/app/webapp

# set work directory
RUN mkdir -p $DockerHOME

# where your code lives
WORKDIR $DockerHOME

# set environment variables

# this ensures that the Python interpreter doesn’t generate .pyc files, we don't need them
ENV PYTHONDONTWRITEBYTECODE 1
# this will send python output straight to the terminal(standard output) without being buffered
ENV PYTHONUNBUFFERED 1

# install dependencies
RUN pip install --upgrade pip

# copy the whole project to your docker home directory.
COPY . $DockerHOME
# run this command to install all dependencies
RUN pip install -r requirements.txt
# port where the Django app runs
EXPOSE 5000
# start the server on port 5000, this is what EB listens for
CMD ["python", "manage.py", "runserver", "0.0.0.0:5000"]

On your local machine, you can test your EB deployment by running

eb inti -p docker _application_name_

and run it with

eb local run --port 5000

To deploy the application, run

eb create _environment_name_

and follow the prompts

When you are done, use

eb open

to open the application

If this tells you to add the URL to ALLOWED_HOSTS, copy the URL and add it to "software" with the name "live" (as we mentioned above) in "configuration" under the environment tab like so.

How to deploy a Spring-boot jar file to ElasticBeanstalk

Cloud has made procuring environments and deploying applications to them a lot easier than it used to be, providing us with different cloud deployments models like IaaS, Paas and Saas. Today we will look at the AWS ElasticBeanstalk, a PaaS (Platform as a Service) that provides us with a ready environment to deploy our applications.

Elastic beanstalk nginx listens on port 5000 so, ensure to make your application listen on port 5000 by adding

server:
   port: 5000

to your application.yaml file or by adding the key "SERVER_PORT" and the value "5000" to the software tab in the configuration tab of your environment on the elastic beanstalk.

After developing your Spring-boot applications, run

mvn install

Go to aws' elastic beanstalk website and create a new application

enter the application’s name
choose "java" as the platform and choose the java version your application is running on.
click on "Upload your code" to select your packaged jar file and wait for the application to be deployed.

You can now click on the application URL provided by elastic beanstalk to access your application

How to install Minikube on Ubuntu

If you tried surfing the internet with the hope of finding how you can install minikube so you could run kubernetes locally, you might not find a complete approach on how to do that. This post guides you through what you need installed before you finally install minikube.

You will need to update and grade your system.

sudo apt-get update && sudo apt-get upgrade -y

The -y allows the update without your prompt.

Install socat, conntrack and apt-transport-https for networking between clusters

sudo apt-get install socat apt-transport-https conntrack

Install curl if you don't have it

sudo apt-get install curl

Minikube needs a driver to run your cluster, it might be docker engine (container-based) or a virtualbox (Vm-based). This guide tells you how to install virtual box. You would still need to install docker engine as the runtime for your clusters anyway, so you might just want to install only docker engine using this link.

sudo apt install virtualbox virtualbox-ext-pack

Follow through and complete the installation of virtual box.

Finally, install minikube

curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
sudo install minikube-linux-amd64 /usr/local/bin/minikube

Test your installation.
