AgroSmart-Top

The top-level repository for the AgroSmart/DroneApp web application.

This repository aims to simplify the deployment of the application, by including some top-level files which must be included one level above the source code which is on IS-AgroSmart/AgroSmart-Web.

Pre-install steps

1. Update the OS.
2. Install Git, Docker, Docker Compose and NPM.

First-time usage

1. Clone this repo with git clone --recurse-submodules https://github.com/IS-AgroSmart/AgroSmart-Top ~/AgroSmart.

2. Change to the deploy branch: cd ~/AgroSmart; git checkout deploy.

3. Install all NPM dependencies on the app/frontend directory by running cd ~/AgroSmart/app/frontend; npm install.

4. Create the file ~/AgroSmart/.env and fill it with the required secrets. Only The Chosen Ones should will have access to the file.

5. To run the app, cd into the ~/AgroSmart directory, and run docker-compose up. Repeat any time the app must be started.

6. Create a starting admin user: run docker exec -it container-django /bin/sh. On the container console:

   • Run python3 manage.py migrate

   • Run python3 manage.py collectstatic

   • Run python3 manage.py createsuperuser and provide the required credentials (username admin, email and password shall be determined by use of rational thought)

7. Set up the gradient style on Geoserver, to be used by the indices. To do so:

   1. Visit <ip>/geoserver/geoserver/web, log in to Geoserver, click on "Styles" on the left bar.
   2. Create a new style, which must be called exactly gradient. Leave the workspace blank and the format as SLD, as default.
   3. Enter the contents of gradient.xml in the text box.
   4. Click the Save button at the bottom of the form.

8. Upload the gradient legend to the Geoserver container: run docker cp gradient.png container-geoserver:/opt/geoserver/data_dir/styles/gradient.png

Not-first-time usage

1. cd ~/AgroSmart
2. docker-compose up

Updating the source code

1. Stop the containers by attaching to their terminal session and pressing Ctrl+C.
2. Make sure that you are in the ~/AgroSmart directory (which you should be, if you are in the same terminal that was running the app).
3. Run git pull --recurse-submodules.
4. Run the server again with PREFIX=$(pwd) docker-compose up.

// TODO

• Verify setup steps.
• Maybe add a Bash script that can be run from a clean install of Ubuntu Server. It should automatically install any required programs and get the app ready for launch. Bonus: use https://www.digitalocean.com/community/tutorials/automating-initial-server-setup-with-ubuntu-18-04 and OVH Horizon's "Script Data" (https://docs.ovh.com/gb/en/public-cloud/create-an-instance-in-horizon/) to execute the Bash script when creating the image.
• Do something about automatically running the app on boot, and separating its stdin/stdout from any specific shell.
