jonpspri opened a new pull request #4204: Update Travis build/test to use Xenial and Docker 18
URL: https://github.com/apache/incubator-openwhisk/pull/4204
 
 
   <!--- Provide a concise summary of your changes in the Title -->
   
   ## Description
   <!--- Provide a detailed description of your changes. -->
   <!--- Include details of what problem you are solving and how your changes are tested. -->
   The legacy Travis build for OpenWhisk uses a depricated Travis engine and Docker 12.  While I know there are conversations around Docker 12 vs a later version, the use of the old Docker prevents use of certain good build features, namely Build Args for image selection and multi-stage builds.
   
   This PR makes these changes:
   
   - Bumps the Travis build to Xenial Ubuntu (the latest supported), which includes Docker 18.
   - Patches Docker 18 service to listen on Port 4243 (TODO: let's get to shared sockets for everything)
   - Adds parameterization for limits.invocations.per.minute to reduce spurious system test failures - separate PR pending
   - Upgrades ephemeral CouchDB to `apache/couchdb:2.3` (to avoid a shared-storage bug) - see also PR #4202 
   - Changes how Ansible detects ansible uptime to use the ansible-cli in the ansible Docker image, rather than make assumptions about the ansible network protocol - separate PR pending
   - Uses the new Box upload proxy (and makes a few tinkers to logging) - see also PR #4200 
   
   I will track other PRs and rebase if they're committed.
