I am trying to deploy a dataflow job using google's predefined template using python api
I do not want my dataflow compute instance to have a public ip, so I use something like this:
GCSPATH="gs://dataflow-templates/latest/Cloud_PubSub_to_GCS_Text"
BODY = {
"jobName": "{jobname}".format(jobname=JOBNAME),
"parameters": {
"inputTopic" : "projects/{project}/topics/{topic}".format(project=PROJECT, topic=TOPIC),
"outputDirectory": "gs://{bucket}/pubsub-backup-v2/{topic}/".format(bucket=BUCKET, topic=TOPIC),
"outputFilenamePrefix": "{topic}-".format(topic=TOPIC),
"outputFilenameSuffix": ".txt"
},
"environment": {
"machineType": "n1-standard-1",
"usePublicIps": False,
"subnetwork": SUBNETWORK,
}
}
request = service.projects().templates().launch(projectId=PROJECT, gcsPath=GCSPATH, body=BODY)
response = request.execute()
but I get this error:
raise HttpError(resp, content, uri=self.uri)
googleapiclient.errors.HttpError: <HttpError 400 when requesting https://dataflow.googleapis.com/v1b3/projects/ABC/templates:launch?alt=json&gcsPath=gs%3A%2F%2Fdataflow-templates%2Flatest%2FCloud_PubSub_to_GCS_Text returned "Invalid JSON payload received. Unknown name "use_public_ips" at 'launch_parameters.environment': Cannot find field.">
If I remove the usePublicIps, it goes through, but my compute instance gets deployed with public ip.
I found one way to make this work
Clone Google Defined Templates
Run the template with custom parameters
mvn compile exec:java \
-Dexec.mainClass=com.google.cloud.teleport.templates.PubsubToText \
-Dexec.cleanupDaemonThreads=false \
-Dexec.args=" \
--project=${PROJECT_ID} \
--stagingLocation=gs://${BUCKET}/dataflow/pipelines/${PIPELINE_FOLDER}/staging \
--tempLocation=gs://${BUCKET}/dataflow/pipelines/${PIPELINE_FOLDER}/temp \
--runner=DataflowRunner \
--windowDuration=2m \
--numShards=1 \
--inputTopic=projects/${PROJECT_ID}/topics/$TOPIC \
--outputDirectory=gs://${BUCKET}/temp/ \
--outputFilenamePrefix=windowed-file \
--outputFilenameSuffix=.txt \
--workerMachineType=n1-standard-1 \
--subnetwork=${SUBNET} \
--usePublicIps=false"
