Automated Deployment with EXRPROXY-ENV

Best suitable to be used with EXRPROXY-ENV autobuild

• Runs indexer, DB, and hasura API endpoint
• requires at least 2vCPU

Autobuild steps

Requirements

• Port 80 must be opened on the host

Follow the Service Node Setup Guide. That guide employs the autobuild tools in the EXR ENV repo to deploy XQuery within an EXR Environment.

Once the XQuery stack has been deployed in the EXR ENV, you can create a project and test the XQuery deployment by following the Project API and the XQuery API.

NOTE: If you want to create a project in the EXR ENV for testing, and you want to avoid making a payment to create the project, check out the projects.py tool in your EXR ENV, located at exrproxy-env/cli/projects.py. Issue projects.py -h for help in using it.
