synthetic_10lps.yaml

# This pod specification creates an instance of a synthetic logger. The logger
# is simply a program that writes out the hostname of the pod, a count which increments
# by one on each iteration (to help notice missing log enteries) and the date using
# a long format (RFC-3339) to nano-second precision. This program logs at a frequency
# of 0.25 lines per second. The shellscript program is given directly to bash as -c argument
# and could have been written out as:
#   i="0"
#   while true
#   do
#     echo -n "`hostname`: $i: "
#     date --rfc-3339 ns
#     sleep 4
#     i=$[$i+1]
#   done
