Golang : Configure crontab to poll every two minutes 8am to 6pm Monday to Friday




Was very busy lately working on a new project for a client. One of the key requirements in the project is to create a micro service to poll from external data sources for every two minutes, from 8am to 6pm, Monday to Friday and update the database with the latest data.

After testing out my Go program. I need to put in a crontab to start polling the data.

From the Linux Crontab configuration, the parameters are in such order :

 MIN HOUR DOM MON DOW CMD

Explanation:

MIN - Minute field and can be 0 to 59

HOUR - Hour field and can be 0 to 23

DOM - Day of Month and can be 1-31

MON - Month field and can be 1-12

DOW - Day Of Week and can be 0-6

CMD - Comman to be executed.

Therefore, to achieve my objective, the final crontab configuration should look like this :

 */2 08-18 * * 1-5 /microservices/go-poll-and-update-summary-data

Hope this helps!
