[GitHub] dgrove-oss opened a new pull request #4052: Switch from alpine to jessie-slim for runner utility images

dgrove-oss opened a new pull request #4052: Switch from alpine to jessie-slim for runner utility images
URL: https://github.com/apache/incubator-openwhisk/pull/4052
 
 
   The Alpine based images have a nasty problem with DNS failures that
   tends to surface when running them in Kubernetes.  After a fair amount
   of poking around, it seems like the only reliable fix is to not use
   Alpine images on Kubernetes until upstream bug fixes in various layers
   of the software stack, including the Linux kernel propagate to the
   Alpine releases.  For more context,
   see:
