Objectives : In this lab, you will:

1. Build and deploy a simple guestbook application
2. Use OpenShift image streams to roll out an update
3. Deploy a multi-tier version of the guestbook application
4. Create a Watson Tone Analyzer service instance on IBM Cloud
5. Bind the Tone Analyzer service instance to your application
6. Autoscale the guestbook app

Step 1) Click on Terminal

• Terminal > New Terminal. New terminal
• cd /home/project
• git clone https://github.com/ajp-io/guestbook.git
• cd guestbook
• ls
• cd v1/guestbook
• cat Dockerfile
• export MY_NAMESPACE=sn-labs-$USERNAME
• export MY_NAMESPACE=sn-labs-staging-$USERNAME

Build the guestbook app.

• docker build . -t us.icr.io/$MY_NAMESPACE/guestbook:v1
• docker push us.icr.io/$MY_NAMESPACE/guestbook:v1
• ibmcloud cr images
• oc tag us.icr.io/$MY_NAMESPACE/guestbook:v1 guestbook:v1 –reference-policy=local –scheduled

Step 2) its time to do Some work in OpenShift

• Open OpenShift
• Switch to develpoper Mode..
• Click the +Add button
• Select container image
• Select
• name / image / version
• and all things leave default —– click create
• Click on Topology.

Then click the guestbook right menu open drag down you can get your website link.
click and open in new tab.

• take #Screenshot 1

On The URL bar at last add this /info your guestbook website and

• take #Screenshot 2

//example = http:// kugdcbio58asdc5154dscuhioad54584a54/info

Step 3) Now updating a guestbook

• Update the guestbook
• In IBM virtual lab open File explorer.
• The path to this file is
• guestbook/v1/guestbook/public/index.html.

Let’s edit the title Guestbook – v1,
change it to include your name. <h1>Lovelake4u Guestbook – v1.
and Save File…

Build and push the app again using the same tag. This will overwrite the previous image.

• docker build . -t us.icr.io/$MY_NAMESPACE/guestbook:v1 && docker push us.icr.io/$MY_NAMESPACE/guestbook:v1
• oc import-image guestbook:v1 –from=us.icr.io/$MY_NAMESPACE/guestbook:v1 –confirm

Wait Few Minutes…your website is updating..
Refresh your website… Now your name appear on it.
take #Screenshot 3

Switch to the Administrator perspective so that you can view image streams.

• Click Builds > Image Streams in the navigation.
• Click the guestbook image stream.
• Click on History
• take #Screenshot 4

Return to the Developer perspective.

• Click on Topology
• then click on guestbook
• take #Screenshot 5

Step 4) its time to Delete the guestbook

Delete the guestbook

• Topology
• click the guestbook-app application.
• This is the light gray circle that surrounds the guestbook Deployment.
• Click Actions > Delete Application.
• Type in the application name and click Delete.

Step 5) its time to Deploy Redis

Deploy Redis master and slave

• cd ../../v2
• cat redis-master-deployment.yaml
• oc apply -f redis-master-deployment.yaml
• oc get deployments
• oc get pods

• cat redis-master-service.yaml
• oc apply -f redis-master-service.yaml
• cat redis-slave-deployment.yaml
• oc apply -f redis-slave-deployment.yaml
• oc get deployments
• oc get pods

• cat redis-slave-service.yaml
• oc apply -f redis-slave-service.yaml

Deploy v2 guestbook app

• Click the +Add button

• Select Dockerfile option.

Paste this in URL

• https://github.com/ajp-io/guestbook

• Click Show Advanced Git Options.

Context Dir box add this

• /v2/guestbook

Under Container Port, enter

• 3000
• leave all things default.
• Click Create.

Topology view,

• take #Screenshot 6
• click the guestbook Deployment. I
• Route location to load the guestbook in the browser.
• Notice that the header says “Guestbook – v2.

// when you put some data it will throw error..

//do not take tension…

Step 6) Now we are Creating Tone Analyzer service
Create a Tone Analyzer service instance

• Go to the IBM Cloud catalog. Click Here
• login with your ibm account.
• Search Tone Analyzer
• Click on it …. select lite version click create..

Get Back to Virtual Lab…

• ibmcloud login -u [your id]
• it will ask your password ttpe and verify it
• after this Set organizatrion
• ibmcloud target -o [org_name]
• after this Set space name
• ibmcloud target -s [space_name]

Run this to get your id name

oc project

//Copy id and paste it on <resource_group> it look like 55417815442sdas1asd4

• ibmcloud target -g <resource_group>

Use the Explorer to edit binding-hack.sh.

The path to this file is

• guestbook/v2/binding-hack.sh.
• You need to insert your OpenShift project where it says <my_project>.

After Run This..

• ./binding-hack.sh

Log back into the lab account.

• ibmcloud login –apikey $IBMCLOUD_API_KEY

• cd analyzer
• docker build . -t us.icr.io/$MY_NAMESPACE/analyzer:v1 && docker push us.icr.io/$MY_NAMESPACE/analyzer:v1
• cd ..

echo $MY_NAMESPACE
// Copy your namespace…

Use the Explorer to edit this file ( analyzer-deployment.yaml )

file path: guestbook/v2/analyzer-deployment.yaml
You need to insert your Container Registry namespace where it says <my_namespace>

Step 7) analyzer Deployment.
Create the analyzer Deployment.

• oc apply -f analyzer-deployment.yaml

• oc apply -f analyzer-service.yaml

Return to the guestbook in the browser,

refresh the page,
and submit a new entry.

• #Screenshot 7

add /info at the last of url and take

• #Screenshot 8

You should see your entry appear along with a tone analysis.

Autoscale guestbook

• ckick on Topology
• click the guestbook Deployment.
• Then click Actions > Edit Deployment.
• In the template.spec.containers section,
• find resources: {}. Replace that with the following text. Make sure the spacing is correct as YAML uses strict indentation.

resources:

• limits:
• cpu: 30m
• memory: 100Mi
• requests:
• cpu: 3m
• memory: 40Mi
• Click Save.

Switch to the Administrator perspective.

Switch to Administrator perspective.

• Select Workloads > Horizontal Pod Autoscalers

• Click Create Horizontal Pod Autoscaler.
• Paste the following YAML into the editor.

• apiVersion: autoscaling/v2beta1
• kind: HorizontalPodAutoscaler
• metadata:
• name: guestbook-hpa
• spec:
• scaleTargetRef:
• apiVersion: apps/v1
• kind: Deployment
• name: guestbook
• minReplicas: 1
• maxReplicas: 3
• metrics:
• – type: Resource
• resource:
• name: cpu
• targetAverageUtilization: 1

Click Create.

Switch to the Administrator perspective so that you can view image streams.

• Click on Workloads
• Then Click the Horizontal Pod Autoscalers
• Click on Overview

• take #Screenshot 9
