When launching a new Perf instance, first determine whether you are creating a Googler-only or a publicly available instance. Based on that, all resources except the GCS bucket will be created in the respective projects mentioned below.
| Instance Type | GCP Project |
|---|---|
| Googlers-only | skia-infra-corp |
| Public | skia-infra-public |
This is the bucket where Skia formatted JSONs are to be uploaded to trigger their ingestion. These buckets live in the skia-public project. To create a new bucket, update this terraform file
Determine which service account will be writing the input files into this bucket and provide that account with objectAdmins permission.
Once created, it's recommended to create a folder specifically for ingestion e.g. gs://flutter-skia-perf-prod/ingest.
This needs to be done from a machine on corp and also requires breakglass to the skia-infra-breakglass-policy group. Note that there is a different connect script for each cluster.
Note: if you're creating a Googler-only instance, use skia-infra-corp instead of skia-infra-public.
Port-forward the database:
$ ./kube/attach.sh skia-infra-public kubectl port-forward --namespace=perf perf-cockroachdb-0 25000:26257
From another shell on the same computer connect to the database:
cockroach sql --insecure --host=127.0.0.1:25000
Create the database:
root@perf-cockroachdb-public:26257/defaultdb> CREATE DATABASE flutter_flutter2; CREATE DATABASE Time: 24.075052ms
Use the newly created database:
root@perf-cockroachdb-public:26257/defaultdb> use flutter_flutter2;
Apply the schema to the database. The schema is found in //perf/go/sql/schema.go.
root@perf-cockroachdb-public:26257/defaultdb> CREATE TABLE ...
./backup/backup.sh.perf-cockroachdb-backup.Run the below cmd from the perf directory.
make push_backup
This creates the topic and subscription.
perf-tool config create-pubsub-topics-and-subscriptions --config_filename=./configs/angle.json
This configures the GCS bucket/directory to send PubSub events to that topic when new files arrive. Update the variable values based on the output of the above step:
#/bin/bash
# Creates the PubSub topic for Android Perf files and then ties it to GCS
# notifications.
set -e -x
PROJECT_ID=skia-public
TOPIC=perf-ingestion-flutter-flutter2
DIRECTORY=flutter-flutter
BUCKET=gs://flutter-skia-perf-prod
gsutil notification create -f json -e OBJECT_FINALIZE -t projects/${PROJECT_ID}/topics/${TOPIC}
-p ${DIRECTORY} ${BUCKET}
Note that for buckets not owned by the Skia Infra team this command needs to be run by someone with admin rights on the bucket and also the ability to create the link to the pubsub receiver in the skia-public project. For non-Skia Infra buckets I've found the easiest thing to do is give the requester privileges to the skia-public project (for an hour) and have them run the above command.
Create a CL like this one to create a service account. Make sure it's in the correct project.
Give this service account read access to the bucket created in step 1 and Pub/Sub Editor role to both the topic and subscription created in step 5.
If you are creating a Googlers-only instance, the service accounts needs to be added to the auth-proxy roster so that it can access secrets in the GCP project. Create a CL like this one to do the same.
In k8s-config repo, create a CL with a *-sa.yaml file which points to the service account created in step 7:
apiVersion: v1
kind: ServiceAccount
metadata:
annotations:
iam.gke.io/gcp-service-account: perf-<XXXX>@<CLUSTER>.iam.gserviceaccount.com
name: perf-<XXXX>-internal
namespace: perf
See this file as an example.
In k8s-config repo, create a CL like this one, where you create a *-maintenance-*.yaml file where you define the maintenance task for your perf instance.
In k8s-config repo, create a CL like this one, where you create a *-sa.yaml file which points to the service account created in step 7, and a *-ingest-*.yaml file where you define the ingestor specs for your perf instance. In the ingest file, make sure to add the appropriate values for app, serviceAccountName and --config_filename.
perf-tool ingest force-reingest --config_filename=./configs/flutter-flutter2.json
In k8s-config repo, create a CL like this one, where you create a *-fe-*.yaml file. Ensure to have appropriate values for app, serviceAccountName, name and --config_filename flags.
Then run skfe/generate.sh. This will create the envoy config to route traffic to the instance.
For skia-infra-public:
For skia-infra-corp:
In k8s-config repo, create a CL like this one. Modify perf.json to include your instance's URL. Then run prober/generate.sh to update allprobersk.json file.
