A way to setup Geodjango for Django 3.2.5 and MySQL 5.7 on Amazon Linux AMI (EC2).

3. Build GDAL and push it to S3
4. Loading and running in ElasticBeanstalk

Setup Elasticbeanstalk

When you create an Eb environment, make sure to se the EC2 keypair (Configure -> Security -> Virtual Machine Key Pair) and note the IAM instance profile that you select. This IAM instance will be used in the next step.

Setup S3

Create (or reuse) an S3 bucket (eg: s3-bucket-name) and folder (eg: path/to/empty/folder) to hold the built GDAL libraries. Configure the Bucket Policy permissions so that your IAM role can do PUT actions to that folder:

  {
      "Principal": {
          "AWS": "__Full ARN of the above IAM role__"
      },
      "Action": [
          "s3:PutObject",
          "s3:PutObjectAcl"
      ],
      "Resource": "arn:aws:s3:::__s3-bucket-name/path/to/empty/folder__/*"
  }

Building GDAL

SSH into EC2 machine and build gdal by copy-pasta the gdal-build-script.sh. The script uses s3 cp to transfer the builds onto the S3 above.

Running in EB

Finally, .ebextension scripts will pull the libs from S3 and simply run them. Use the example implementation in .ebextensions/ folder here.
