k8s-logger v1.4

Changes

• Update usage with new option, -c
• Add debug option, -d to log to stderr as well
• Add -p file.pid to allow overriding default PID file

Fixes

• Close and reopen FIFO on POLLHUP, i.e., when the other end
  closes its file descriptor. This fixes a 100% CPU load issue
  seen in Infix when stopping containers
