  • oc get deployments
  • oc get pods

ย 

  • 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

  • after this Set organizatrion
  • ibmcloud target -o [org_name]
  • after this Set space name
  • ibmcloud target -s [space_name]

ย 

ย 

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

ย 

After Run This..

./binding-hack.sh

  • Log back into the lab account.
  • ibmcloud login –apikey $IBMCLOUD_API_KEY

ย 

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…

  • memory: 40Mi
  • Click Save.

Switch to the Administrator perspective.

  • Switch to Administrator perspective.
