[Spacewalk-list] server says client should be updated, but nothing happens

[Bill Howe]

We use cron to run a "date checker" type script. The date checker script
can add the functionality you describe (first Monday).
The script will determine whether or not to execute a python scheduler
script. (this uses the python API to schedule updates)

The example below executes a date checker script every Monday.
The date checker script then determines if the next day is the first,
second, or third Tuesday of the month.
If so, it runs the scheduler python script to actually schedule the updates
in either Dev, Test, or Prod.

*---- Cron Job ----*
/etc/cron.d/os-updates-checker

#-Target: Run on the Mon before 1st,2nd,3rd Tues of month (Dev,Test,Prod
Patch Days)
00 08 * * mon  root  /scripts/os-updates/schedule-updates-check.sh

--* Date Check Script: schedule-updates-check.sh* --

#!/bin/bash
# Title: schedule-updates-check.sh
# Description: Determine if Schedule Updates should be run
#   The scheduler should run on the Monday before each environment patch
day.
#   The updates should be scheduled to deploy on Tuesday at 0800.

# Script to execute (environment is filled in during the if block)
script="/scripts/os-updates/schedule-updates.py --days 1 --group all_"

# Log file
log_file="/var/log/os-updates/schedule-updates-check.log"

echo "==== Log Started: $(date) ====" >> ${log_file}

# If today is Monday AND 1 day from now is >=1 and <=21(1st,2nd,3rd Tue)
if [[ "$(date '+%a')" == "Mon" ]] && [[ $(date +%-d -d "+1 day") -ge 1 ]];
then
  # First Tue: Development
  if [[ $(date +%-d -d "+1 day") -le 7 ]]; then
    echo ">> OK: One day from now is the first Tue of the Month; execute
script(${script}dev)." >> ${log_file}
    ${script}dev 2>&1 >> ${log_file}

  # Second Tue: System Test
  elif [[ $(date +%-d -d "+1 day") -le 14 ]]; then
    echo ">> OK: One day from now is the second Tue of the Month; execute
script(${script}test)." >> ${log_file}
    ${script}systest 2>&1 >> ${log_file}

  # Third Tue: Production
  elif [[ $(date +%-d -d "+1 day") -le 21 ]]; then
    echo ">> OK: One day from now is the third Tue of the Month; execute
script(${script}prod)." >> ${log_file}
    ${script}prod 2>&1 >> ${log_file}

  else
    echo ">> NO-EXEC: One day from now is NOT the first,second, or third
Tue of the Month. Will NOT execute script(${script})." >> ${log_file}
  fi
else
  echo ">> NO-EXEC: One day from now is NOT the first,second, or third Tue
of the Month. Will NOT execute script(${script})." >> ${log_file}
fi

echo -e "==== Log Ended: $(date) ====\n" >> ${log_file}
