FastX 5: Job Scheduling Migration Cheat Sheet

This is a summary of the changes discussed in job scheduling reimagined.

Migrate Apps

mkdir -p /etc/fastx/schedule

foreach app in /etc/fastx/apps
    if there is a parameter named scheduleDir
        Copy the scheduleDir directory into /etc/fastx/schedule

    #update the app 
    # scheduleDir=/path/to/my_scheduler
    [schedule]
       dir=my_scheduler

 
    # if there is a parameter named [nodeMetadataFilter]
    [schedule.data]
    metaKey1=metaVal1
    metaKey2=metaVal2

Migrate Forms

foreach file in /etc/fastx/forms
   extract the html field and put it into a file formid.html

foreach app  in /etc/fastx/apps
if it has a forms array
   find the form id
   find the [schedule.dir] in the app
   cp formid.html /etc/fastx/schedule/[schedule.dir]/form.html

   if the formid was actually using a script, copy the script into /etc/fastx/schedule/[schedule.dir]/form_script
 
delete the forms parameter as it is no longer used
delete the overrideDefaultForms as it is no longer used
