I have a AWS Cloud9 Instance that starts running at 11:52 PM MST and stops running at 11:59 PM MST. I have a dockerfile within the Instance that when ran with the correct mount will run a set of c++ .cpp files that collect live web data. The ultimate goal of this instance is to be fully automatic so that every night it collects the live web data for that date, hence why the Instance is open at the very end of the day each night. Is it possible to have my AWS Instance run a given command in a terminal window at a certain time, say 11:55 PM or even upon startup. So at the time, or at startup, the command "docker run -it...." is ran within the instance.
Is automating this process possible? I have looked into CloudWatch events and think that might be the best way to go about automating this process but I am not quite sure how I would create a rule to fulfill the job. If it is not possible to automate a certain command within a terminal window, could I automate the dockerfile to run at a certain time?
ofcourse you can automate running of commands not just docker but for the fact any commands using cron daemon. all you need to do is place your command in shell script file say doc.sh in your desired directory.
crontab -ea b c d e /directory/commandwhere a -Minute, b-hour c-day d-month e-day of the week
the /directory/command specifies the location and script you want to run.
