High Availability

[rduplain]

While qwerty.sh APIs are stable, a v1.0 release depends on first-class support for highly available hosting of https://qwerty.sh.

Pre-v1.0 hosting of qwerty.sh is a single server on DigitalOcean. High availability through GitHub's raw hosting is a configuration option.

To achieve first-class support for high availability:

• At least, add a Dockerfile to enable self-hosting options for high availability.
• At most, load-balance public hosting of qwerty.sh across multiple availability zones.

The script-as-as-service design of qwerty.sh makes it a read-only service, amenable to hosting by ephemeral servers. It's helpful to support git fetch on production servers in order to make pre-release versions available at https://qwerty.sh/master.
