Use labels on Cloud Run services for a billing breakdown#

Thanks to @glasnt for the tip on this one. If you want a per-service breakdown of pricing on your Google Cloud Run services within a project (each service is a different deployed application) the easiest way to do it is to apply labels to those services, then request a by-label pricing breakdown.

This command will update a service (restarting it) with a new label:

1
gcloud run services update csvconf --region=us-central1 --platform=managed --update-labels service=csvconf

I found it needed the --platform=managed and --region=X options to avoid it asking interactive questions.

Here’s a bash script which loops through all of the services that do NOT have a service label and applies one:

1
#!/bin/bash
2
for line in $(
3
  gcloud run services list --platform=managed \
4
    --format="csv(SERVICE,REGION)" \
5
    --filter "NOT metadata.labels.service:*" \
6
  | tail -n +2)
7
do
8
  IFS=$','; service_and_region=($line); unset IFS;
9
  service=${service_and_region[0]}
10
  region=${service_and_region[1]}
11
  echo "service: $service    region: $region"
12
  gcloud run services update $service \
13
    --region=$region --platform=managed \
14
    --update-labels service=$service
15
  echo
16
done

It runs the equivalent of this for each service:

1
gcloud run services update asgi-log-demo --region=us-central1 --platform=managed --update-labels service=asgi-log-demo

I saved that as a runme.sh script, run chmod 755 runme.sh and then ./runme.sh to run it.

The output of the script looked like this (one entry for each service) - each one took ~30s to run.

1
Service [covid-19] revision [covid-19-00122-zod] has been deployed and is serving 100 percent of traffic at https://covid-19-j7hipcg4aq-uc.a.run.app
2
✓ Deploying... Done.
3
  ✓ Creating Revision...
4
  ✓ Routing traffic...
5
Done.

I had to wait a couple of days for this to take effect, but once it did I could get results by visiting Billing -> Reports, then selecting service from the group by menu here:

The graph (I picked bar chart over line chart) looked like this:

Using the metrics explorer#

Even without setting up these extra service labels the Metrics explorer can show you breakdowns of billing time against different services.

Here’s how to configure that:
