Droplet support

UPDATE: please test the current script at https://github.com/ProxeusApp/proxeus-core/tree/main/deploy/digitalocean

Please document how to deploy Proxeus into Digital Ocean, in a few words like we did with Linode here: https://github.com/ProxeusApp/proxeus-core/tree/master/deploy/linode

Ideally also include a Droplet configuration file: https://docs.digitalocean.com/tutorials/recommended-droplet-setup/

This would allow Proxeus users to easily deploy to another popular hosting platform.

@tafonina please close once this is done

Currently Docker builds - e.g. the latest tag here - are failing with an error like this:

Step 6/10 : COPY artifacts/proxeus-docker /app/proxeus
ERROR: Service 'platform' failed to build: COPY failed: file not found in build context or excluded by .dockerignore: stat artifacts/proxeus-docker: file does not exist

Please check that changes on this branch did not affect the inclusion of build artifacts (binaries) in the Docker image.

@tafonina let's retest this, new release should work better.

Please test and close while deploying demo server.

The server is up and running as expected in DigitalOcean. I will do a bit of additional testing.

My main concern is that it still takes knowledge of Unix shell to follow the instructions. We need to simplify the instructions more, or look another option in a further issue.

Use a custom image (note that it is limited to a specific geographic cloud)

Instruct users to paste the init script into Advanced options:

Go through approval process to get Proxeus into the Marketplace
