Cloud Scheduler - Terrafrom - How to pass current date in CloudSheduler body

Question

Am using cloudScheduler to schedule the dataflow job. Where i need to pass the rundate/runtime/current date dynamically to dataflow job using cloudsheduler body. Am reading the body parameters using Java Options in Dataflow job code.

Looking for syntax to read header X-CloudScheduler-ScheduleTime in cloudschduler body

body = base64encode(<<-EOT { "jobName": "${each.value.name}_${http_target.h}", "parameters": { "bigtableInstanceId": "${var.cloudscheduler_bigtable_instanceid}", "bigtableProjectId": "${var.project_id}", "bigtableTableId": "${each.value.bigtableTableId}", "inputFilePattern": "${each.value.inputFilePattern}", "runningdate":????????
"region": "${var.cloudscheduler_region}", }, "environment": { "numWorkers": "2", "tempLocation": "gs://gcslocation/temp2", "zone": "${var.cloudscheduler_region}-a" } } EOT ) }

How to pass the scheduled date/rundate in the body "runningdate":???????? of cloudscheduler which we read in dataflow job code.

Answer 1

(Simple Approach) Try using Cloud Functions rather than Cloud Scheduler .

Cloud Scheduler is supposed work like a unix cron job, to schedule and run jobs.

Cloud Functions are mainly useful for uses cases where arguments need to be parsed & dynamic decision to be made like should I run Dataflow job or any as such.

If you have requirement/such use case to use Cloud Scheduler , then what you can do is

• Use Cloud Functions to record your arguments and store in commonly accessible locations like DB or Bucket
• Use Cloud Scheduler to do the required step after that.

If I misunderstood, your question, please do elaborate with more details & examples.
