Google Cloud Run Services¶

Step-01: Introduction¶

Create a Cloud Run Service
Update Applications
Revision URLs
Traffic Splitting
Autoscaling
Implement all the above features using gcloud run

Step-02: Create Service and Access it¶

Go to Cloud Run -> Create Service
Deploy one revision from an existing container image: stacksimplify/google-cloud-run:v1
Service Name: myservice1
Authentication: Allow unauthenticated invocations
Container port: 80
REST ALL LEAVE TO DEFAULTS

Click on CREATE

# Docker Image used
stacksimplify/google-cloud-run:v1

# Access Application on Browser
https://myservice1-czbx2i66ca-uc.a.run.app

Step-03: Update Application - v2¶

Go to Cloud Run -> myservice1 -> EDIT & DEPLOY NEW REVISION
Deploy one revision from an existing container image: stacksimplify/google-cloud-run:v2
Serve this revision immediately: CHECKED

Click on DEPLOY

# Docker Image used
stacksimplify/google-cloud-run:v2

# Access Application on Browser
https://myservice1-czbx2i66ca-uc.a.run.app

Step-04: Cloud Run Revisions and Traffic Splitting¶

Split Traffic between version 1 and version 2
version-1: 50%

version-2: 50%

# Access Application on Browser
https://myservice1-czbx2i66ca-uc.a.run.app

Step-05: Add Revision URLs¶

Add Revision URLs
version-1: myappv1

version-2: myappv2

# myappv1 Revision URL
https://myappv1---myservice1-czbx2i66ca-uc.a.run.app/

# myappv2 Revision URL
https://myappv2---myservice1-czbx2i66ca-uc.a.run.app/

Step-06: Deploy V3 Application with Serve this revision immediately UNCHECKED¶

Go to Cloud Run -> myservice1 -> EDIT & DEPLOY NEW REVISION
Deploy one revision from an existing container image: stacksimplify/google-cloud-run:v3
Serve this revision immediately: UNCHECKED

Click on DEPLOY

# Docker Image used
stacksimplify/google-cloud-run:v3

# Access Application on Browser 
https://myservice1-czbx2i66ca-uc.a.run.app
Observation: V2 version will be still serving

Add Revision URL for V3¶

version-3: myappv3

# Access Application on Browser using Revision URL
https://myappv3---myservice1-czbx2i66ca-uc.a.run.app/
Observation: 
1. V2 version will be still serving
2. V3 is not live, can be tested using revision URL.

Traffic Split to V3: 10%¶

# Access Application on Browser using Revision URL
https://myservice1-czbx2i66ca-uc.a.run.app/
Observation: 
1. V2 version will be serving 90%
2. V3 version will be serving 10% - Gradual Rollout

Step-07: Traffic Splitting¶

version-1: 33%
version-2: 33%

version-3: 34%

# Access Application on Browser using Revision URL
https://myservice1-czbx2i66ca-uc.a.run.app/
Observation: Traffic splits between 3 versions

Step-08: Verify Additional Tabs¶

Verify Logs Tabs
Verify Metrics Tabs
Verify Security Tabs

Step-09: Cloud Run Autoscaling¶

Cloud Run Autoscaling
Discuss about the concepts
Minimum number of instances
Maximum number of instances
Cold Starts

Step-10: gcloud: Create Google Cloud Run Service¶

# gcloud Project Settings
gcloud config list
PROJECT_ID=[YOUR-PROJECT-ID]
PROJECT_ID=kdaida123
REGION=us-central1
gcloud config set core/project $PROJECT_ID
gcloud config set run/region $REGION
gcloud config list

# Help
gcloud run services --help
gcloud run deploy --help

# List Cloud Run Services
gcloud run services list

# Create Google Cloud Run Service
gcloud run deploy myservice102 \
--image=stacksimplify/google-cloud-run:v1 \
--allow-unauthenticated \
--port=80 

# List Cloud Run Services
gcloud run services list

# Describe Cloud Run Service
gcloud run services describe myservice102

Step-11: gcloud: List and Describe Revisions¶

# Help 
gcloud run revisions --help

# List Revisions
gcloud run revisions list

# Describe Revision
gcloud run revisions describe <Revision-Name> 
gcloud run revisions describe myservice102-00001-2rk

Step-12: gcloud: Update Application¶

# Update Application 
gcloud run services update
gcloud run services update --help 

# Update Application 
gcloud run services update myservice102 --image=stacksimplify/google-cloud-run:v2

# List Revisions
gcloud run revisions list 

# Describe Revision
gcloud run revisions describe <Revision-Name> 
gcloud run revisions describe myservice102-00001-2rk

Step-13: gcloud: Update Traffic¶

# Help
gcloud run services update-traffic --help

# List Revisions
gcloud run revisions list 

# Set Tags (Add Revision URLs)
gcloud run services update-traffic myservice102 \
--set-tags=myappv1=myservice102-00001-2rk,myappv2=myservice102-00002-xgl 

# Update Traffic - V1-50%, V2-50%
gcloud run services update-traffic myservice102 \
--to-revisions=myservice102-00001-2rk=50,myservice102-00002-xgl=50 

## 1. You can also refer to the current or future LATEST revision in --to-revisions by the string "LATEST". 
## 2. To set 10% of traffic to always float to the latest revision:
gcloud run services update-traffic myservice102 \
--to-revisions=myservice102-00001-2rk=100,myservice102-00002-xgl=0 
gcloud run services update-traffic myservice102 --to-revisions=LATEST=10 

# To assign 100% of traffic to the current or future LATEST revision run
gcloud run services update-traffic myservice102 --to-latest

Step-14: gcloud: Delete Cloud Run Service¶

# List Cloudn Run Services
gcloud run services list 

# Delete Cloud Run Service
gcloud run services delete myservice102 
gcloud run services delete myservice1
