how I validate changes and deploy updates to derivationmap.net website

On my local server, I make changes to the local file and then validate using

cd ~/version_controlled/allofphysicsgraph/proofofconcept/v7_pickle_web_interface
docker-compose up --build --remove-orphans

Build time is 10 minutes when layers are not cached.

Check the result in a local web browser by visiting http://localhost If I'm happy with the content,

git add filename
git commit -m "a message"
git push

SSH to the DigitalOcean droplet VPS (virtual private server)

cd ~/proofofconcept/v7_pickle_web_interface
git pull
docker-compose up --build --force-recreate --remove-orphans --detach
