Docker 19.x is not recognized

[mwvaughn]

The abaco deploy workflow checks the major version reported by docker --version to detect a workable Docker installation. The CLI is intended for use with Docker CE 17+. However, the Docker Desktop is shipping Docker version 19.03 as of 8/1/2019 and that is not interpreted correctly by abaco deploy

Resolved in 893bbac - as an aside, there has to be a smarter pure-Bash way of interpreting version strings than what we have written.

Reopening to test

@mwes and @georgebzheng are seeing issues with the latest docker build (~version 20), we'll workaround for now locally. This will likely affect others as they upgrade to Docker engine 20.10.0+

Fixed in master and v1.3.1 in commit 2217e3a
