Aqui eu estava pensando no seguinte esquema: ter uma hora base a noite e variar a hora e minuto a partir do qual a atualização do índice vai ocorrer todo dia. Isso pode ser resolvido conforme o script em bash abaixo:


BASE_HOUR=20

random_time() {
  RANDOM_HOUR=$((RANDOM % 4))
  RANDOM_MIN=$(printf "%02d" $((RANDOM % 60)))
  RANDOM_TIME=$((BASE_HOUR + RANDOM_HOUR))":"$RANDOM_MIN
  echo $RANDOM_TIME
}

# gera sequencia de 10 horários aleatórios para teste
for i in {1..10}; do
  echo `random_time`
done

Neste caso, a partir das 20h ele vai gerar um horário aleatório pro cronjob rodar. Pode ser criada duas funções uma pra retornar a hora e houra pra retornar o minuto.


# Add the cronjob to the crontab
echo "$RANDOM_MINUTE $RANDOM_HOUR * * * python3 solr_cli.py -u $SOLR_URL -c $SOLR_COLLECTION --update-index" >> /etc/cron.daily/update_solr_index

# Start the cron daemon
crond -f -L /dev/stdout
else
echo "Solr is offline, not possible to connect."
