Bash : fail the build after 5 minutes-CodePudding

Idea is to get the status of the deployment after the deployment command is run, If the status says Pending, sleep for 30 seconds and check again untill the status is Completed, catch here being, timeout is 300 seconds. (if the deployment is not Completed within 300 seconds, exit with return code 1.)

service_ui_staus=$(command to check the deployment of UI service)
service_db_staus=$((command to check the deployment of DB service)

    for i in $(seq 1 5); do 
        if [[ "${service_ui_staus}" =~ "Completed" && "${service_db_staus}" =~ "Completed" ]]; then echo "Deployments done..."
            break
        else 
            sleep 30
    done

Above logic is not elegant and I've to add few more validations in the else part to fail the build, if the deployment is not completed within 300 seconds.

Any help in handling this scenario in more generic and elegantly, thanks.

I don't think that you can do it "generically" in a different manner.

#!/bin/bash

time_limit=300
sleep_time=30

for (( i = time_limit; i > 0 ; i -= sleep_time ))
do
    service_ui_staus=$(command to check the deployment of UI service)
    service_db_staus=$((command to check the deployment of DB service)
 
    [[ "${service_ui_staus}" =~ "Completed" && "${service_db_staus}" =~ "Completed" ]] && break

    sleep "$sleep_time"
done

if (( i > 0 ))
then
    echo "Deployments done..."
else
    commands to kill the deployment processes
    exit 1
fi

    if  [ "$counter" -eq "$maxcount" ]; then

        break 
    else

        sleep "$waittime"

done

$ ./script.sh
