Running Geo Django on ElasticBeanstalk

I want to tell you this story because I wasted about 14 hours to realize how to achieve it correctly...
Sometimes working with Elastic Beanstalk can be like this:

Long story short

To successfully run GeoDjango on Elasticbeanstalk container using Python 3.6 you need to follow these steps:
  1. Launch EC2 instance from ElasticBeanstalk image ami-0a2fbeb2675c47493. NB! Do not use EC2 instances under the control of ElasticBeanstalk for that purpose. Launch an instance from the source image used by Beanstalk;
  2. Install GDAL 2;
  3. Create a custom AMI;
  4. Run your Django app using this AMI.

The road so far

We have been using ElasticBeanstalk for 2 years to deploy our Django application in one of our projects. However, we weren’t using Geocoding features for our Django app. In one of our services, we decided to use Geo features of Django and enable PostGIS support for the project.
The problem was with missing GDAL 2 library, required for Django. There is GDAL 1 in Amazon Linux’s repositories, but it’s outdated dependency to make Django enable its GeoSpatial features.
I tried to build it from sources, installed on running instance and deployed code. Everything was fine, but I wanted to make it more reliable and be sure that it would work constantly because my changes would be deleted by autoscaling. Hence, I wanted to build a custom AMI image with required libraries (I needed two more, that didn't exist in repositories).
Okay. I ran a clean configuration of the Elastic Beanstalk environment, installed everything, and created a custom AMI from EC2 instance I created using ElasticBeanstalk.
Seems pretty easy, I thought. I tried to create a new environment using this image and I found a problem with environment variables. For an unknown reason, Python container didn’t see the variables I set in the web interface.
I tried to set them using ebcommand and tried to set them using .ebextensions. Finally, I set them manually and had luck running the Django app, but it was unable to deploy it using eb deploycommand.
In the next step I tried to use an updated image with Python 3.7 and Amazon Linux 2, but there were a lot of differences between Amazon Linux and Amazon Linux 2 that required a lot of changes in my deployment configuration.
I started thinking about what’s wrong with my configuration and why it didn't work. I made a suggestion, that I built custom AMI wrong way and I started from the beginning.

Creating Custom AMI

  1. Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/;
  2. Choose Launch Instance;
  3. Choose Community AMIs;
  4. Insert ami-0a2fbeb2675c47493 to a search bar;
  5. Choose Select to select the AMI;
  6. Launch instance;
  7. Connect with SSH.
Building GDAL
sudo yum -y update
sudo yum-config-manager --enable peel
sudo yum -y install make automake gcc gcc-c++ libcurl-devel proj-devel geos-devel
cd /tmp
curl -L http://download.osgeo.org/gdal/2.0.0/gdal-2.0.0.tar.gz | tar zxf - cd gdal-2.0.0/ ./configure --prefix=/uslocal --without-python make -j4 sudo make install

  1. Go to EC2 Instances page;
  2. Select created instance;
  3. Go to Actions -> Images -> Create image.

Running ElasticBeanstalk using newly created image

Create an EB environment as you got used to it, you need to do the following steps:
  1. Go to “Configure More options”;
  2. Go to Capacity;
  3. Click Edit;
  4. Paste ID of a new image in AMI ID field;
  5. Press save;
  6. Configure rest parameters;
  7. Launch application.
Deploy your Django application and enjoy it!
P. S. Try to move to EKS, sometimes Beanstalk can get you some problems:
  1. Elastic Beanstalk is a wrapper around Amazon Elastic Container Service and it already has some automation (by choosing actions in the UI interface). Thus you can’t well describe your Infrastructure using the IaaC approach.
  2. The instances in each environment run the same set of containers. For instance, you have one frontend application and one backend application. You can’t scale them independently from each other.
  3. It has a hard limit of 4KB to store all key-value pairs, thus you can’t set as many env variables as you want.
  4. One Elastic Beanstalk task is one ECS cluster (EC2 mode).
But it has the following pros:
  1. It’s one of the easiest ways to deploy a simple application to AWS;
  2. AWS Elastic Beanstalk is a good choice for a newly started application on a staging environment;
  3. It offers multi-container Docker;
  4. Has a user-friendly UI.
And, it also has some cons:
  1. It loses independently schedule a replicated set of apps on the cluster;
  2. One Elastic Beanstalk task is one ECS cluster (EC2 mode).


I hope my experience safe your time and you run successfully GeoDjango on Elasticbeanstalk container. Good luck with your next Beanstalk deployment.

Extracting a CFN template from an existing architecture

So I've made a bit of research to try to avoid writing down a CFN template for an architecture I had already set up and which I want to reproduce elsewhere. Here are my findings:
Alternatively, in a similar spirit, there is also (but you have to manually recreate your whole architecture in the Console while it's recording your actions):
I do, however, want the result to be reusable by other people.
Are you guys aware of whether or not there will be a layer of abstraction for the location of the deployment, for example? Something that would allow, say, a us-west-1 parameter rather than directly using the ca-central-1 being used by my stack.
Considering that the CloudFormer warns about the fact that it'll temporarily create resources, and because I'm running on a Free Tier that is already maxed out, I'm kind of on the hold for trying this stuff.
Both Former2 and Console Recorder avoid mentioning whether or not they create resources in order to generate a template.
... so for now I'm trying to avoid running anything, and would love to get some community insight. :)
EDIT: Because someone asked for it, you can understand a bit better where I'm coming from with this reddit post I made yesterday.
The actual stack is:

My setup:

  • ECS (for EC2, not Fargate)
    • Cluster
    • Service
    • Task Definition
    • IAM Role (created automatically by ECS)
  • EC2 (On-Demand, t2.micro, AMI: ECS-Optimized Amazon Linux 2) : mostly managed by the ECS Cluster
    • Auto-Scaling Group (desired 1, min 0, max 1)
    • EBS Volume (Prevent deletion, 30GB, gp2)
    • Key Pair
    • Security Group
    • Launch Configuration
    • Elastic IP (on re-create if your instance dies, configured to be associated automatically!)
  • Cost Explorer -> Budget Alarm

ECS configuration

Initial set up was done through following this tutorial.
Then, to customize the set up to work with GitHub Actions, the following changes were made:
  1. Changed the containerPort of PortMapping from 80 to 80.
  2. Removed the commands that was setting up a default HTML page to land on.
  3. Updated the entryPoint to match a jar execution: java, -jar, /app.jar.
  4. Edit the build.gradle file so that jars do not include version numbers and include Shadow plugin.
  5. Add a Dockerfile which extends our JDK (alpine version) and copies the generated jar.
  6. Added a workingDirectory value of /.
  7. Changed the image to point toward our Docker Hub repository.
  8. Enforced the requiresCompatibilities to be EC2.
  9. The minimum healthy percentage modified from 100% to 0%, and maximum from 200% to 100%: this is to ensure that we can kill a running task and then start a new one, and never have more than 1 task in the Container. See this SO answer to understand better.
