This page shows you how to deploy Kf Cloud Service Broker for Google Cloud and use it to provision or deprovision backing resources. Read about the concepts and architecture to learn more about the Kf Cloud Service Broker.
Set up a Google Service Account (GSA) for Kf Cloud Service Broker
Create a Google Service Account.
gcloud iam service-accounts create csb-${CLUSTER_NAME}-sa \
--project=${CLUSTER_PROJECT_ID} \
--description="GSA for CSB at ${CLUSTER_NAME}" \
--display-name="csb-${CLUSTER_NAME}"
Grant roles/cloudsql.client permissions to the Service Account. This is required to connect the Kf Cloud Service Broker pod to the Cloud SQL for MySQL instance through Cloud SQL Auth proxy.
If everything is installed and configured correctly, you should see the following:

Read about the [concepts and architecture](/migrate/kf/docs/2.4/concepts/cloud-sb-overview) to learn more about the Kf Cloud Service Broker.\n\nCreate environment variables\n----------------------------\n\n### Linux\n\n```\nexport PROJECT_ID=YOUR_PROJECT_ID\nexport CLUSTER_PROJECT_ID=YOUR_PROJECT_ID\nexport CLUSTER_NAME=kf-cluster\nexport INSTANCE_NAME=cloud-service-broker\nexport COMPUTE_REGION=us-central1\n```\n\n### Windows Powershell\n\n```\nSet-Variable -Name PROJECT_ID -Value YOUR_PROJECT_ID\nSet-Variable -Name CLUSTER_PROJECT_ID -Value YOUR_PROJECT_ID\nSet-Variable -Name CLUSTER_NAME -Value kf-cluster\nSet-Variable -Name INSTANCE_NAME -Value cloud-service-broker\nSet-Variable -Name COMPUTE_REGION -Value us-central1\n```\n\nSet up the Kf Cloud Service Broker database\n-------------------------------------------\n\n1. Create a Cloud SQL for MySQL instance.\n\n **Note:** Read [Creating and managing MySQL users](/sql/docs/mysql/create-manage-users) for Cloud SQL for MySQL and set a secure password for the default `root` user. \n\n gcloud sql instances create ${INSTANCE_NAME} --cpu=2 --memory=7680MB --require-ssl --region=${COMPUTE_REGION}\n\n2. Create a database named `servicebroker` in the Cloud SQL for MySQL instance.\n\n **Note:** Document the database name since it is used in later steps. \n\n ```\n gcloud sql databases create servicebroker -i ${INSTANCE_NAME}\n ```\n3. Create a username and password to be used by Kf Cloud Service Broker.\n\n **Note:** Document these values since they will be used in later steps. \n\n ```\n gcloud sql users create csbuser -i ${INSTANCE_NAME} --password=csbpassword\n ```\n\nSet up a Google Service Account (GSA) for Kf Cloud Service Broker\n-----------------------------------------------------------------\n\n1. Create a Google Service Account.\n\n ```\n gcloud iam service-accounts create csb-${CLUSTER_NAME}-sa \\\n --project=${CLUSTER_PROJECT_ID} \\\n --description=\"GSA for CSB at ${CLUSTER_NAME}\" \\\n --display-name=\"csb-${CLUSTER_NAME}\"\n ```\n2. Grant `roles/cloudsql.client` permissions to the Service Account. This is required to connect the Kf Cloud Service Broker pod to the Cloud SQL for MySQL instance through Cloud SQL Auth proxy.\n\n ```\n gcloud projects add-iam-policy-binding ${CLUSTER_PROJECT_ID} \\\n --member=\"serviceAccount:csb-${CLUSTER_NAME}-sa@${CLUSTER_PROJECT_ID}.iam.gserviceaccount.com\" \\\n --role=\"roles/cloudsql.client\"\n ```\n3. Grant additional Google Cloud permissions to the Service Account.\n\n **Note:** In the example below, we grant IAM roles required to provision an instance of Cloud SQL for MySQL and [Memorystore](/memorystore). You must grant this service account the appropriate roles to provision instances of other Google Cloud managed services listed in `kf marketplace`. \n\n ```\n gcloud projects add-iam-policy-binding ${CLUSTER_PROJECT_ID} \\\n --member=\"serviceAccount:csb-${CLUSTER_NAME}-sa@${CLUSTER_PROJECT_ID}.iam.gserviceaccount.com\" \\\n --role=\"roles/compute.networkUser\"\n ``` \n\n ```\n gcloud projects add-iam-policy-binding ${CLUSTER_PROJECT_ID} \\\n --member=\"serviceAccount:csb-${CLUSTER_NAME}-sa@${CLUSTER_PROJECT_ID}.iam.gserviceaccount.com\" \\\n --role=\"roles/cloudsql.admin\"\n ``` \n\n ```\n gcloud projects add-iam-policy-binding ${CLUSTER_PROJECT_ID} \\\n --member=\"serviceAccount:csb-${CLUSTER_NAME}-sa@${CLUSTER_PROJECT_ID}.iam.gserviceaccount.com\" \\\n --role=\"roles/redis.admin\"\n ```\n4. Verify the permissions.\n\n **Warning:** Replace the `CSB_SERVICE_ACCOUNT_NAME` variable in the YAML below with the full service account resolved from `csb-${CLUSTER_NAME}-sa@${CLUSTER_PROJECT_ID}.iam.gserviceaccount.com` \n\n ```\n gcloud projects get-iam-policy ${CLUSTER_PROJECT_ID} \\\n --filter='bindings.members:serviceAccount:\"CSB_SERVICE_ACCOUNT_NAME\"' \\\n --flatten=\"bindings[].members\"\n ```\n\nSet up Workload Identity for Kf Cloud Service Broker\n----------------------------------------------------\n\n1. Bind the Google Service Account with the Kubernetes Service Account.\n\n ```\n gcloud iam service-accounts add-iam-policy-binding \"csb-${CLUSTER_NAME}-sa@${CLUSTER_PROJECT_ID}.iam.gserviceaccount.com\" \\\n --project=${CLUSTER_PROJECT_ID} \\\n --role=\"roles/iam.workloadIdentityUser\" \\\n --member=\"serviceAccount:${CLUSTER_PROJECT_ID}.svc.id.goog[kf-csb/csb-user]\"\n ```\n2. Verify the binding.\n\n ```\n gcloud iam service-accounts get-iam-policy \"csb-${CLUSTER_NAME}-sa@${CLUSTER_PROJECT_ID}.iam.gserviceaccount.com\" \\\n --project=${CLUSTER_PROJECT_ID}\n ```\n\nSet up a Kubernete Secret to share configuration with Kf Cloud Service Broker\n-----------------------------------------------------------------------------\n\n1. Create a config.yml file.\n\n **Note:** Replace the default user/password if desired. Ensure you have set the `CLUSTER_PROJECT_ID` in the [Create environment variables](#create_env_variables) step. \n\n cat \u003c\u003c EOF \u003e\u003e ./config.yml\n gcp:\n credentials: \"\"\n project: ${CLUSTER_PROJECT_ID}\n db:\n host: 127.0.0.1\n password: \u003cvar translate=\"no\"\u003ecsbpassword\u003c/var\u003e\n user: \u003cvar translate=\"no\"\u003ecsbuser\u003c/var\u003e\n tls: false\n api:\n user: \u003cvar translate=\"no\"\u003eservicebroker\u003c/var\u003e\n password: \u003cvar translate=\"no\"\u003epassword\u003c/var\u003e\n EOF\n\n2. Create the `kf-csb` namespace.\n\n kubectl create ns kf-csb\n\n3. Create the Kubernetes Secret.\n\n kubectl create secret generic csb-secret --from-file=config.yml -n kf-csb\n\nInstall Kf Cloud Service Broker\n-------------------------------\n\n1. Download the `kf-csb.yml`.\n\n gcloud storage cp gs://kf-releases/csb/v1.0.0/kf-csb.yaml /tmp/kf-csb.yaml\n\n2. Edit `/tmp/kf-csb.yaml` and replace placeholders with final values. In the example below, `sed` is used.\n\n sed -i \"s|\u003cGSA_NAME\u003e|csb-${CLUSTER_NAME}-sa@${CLUSTER_PROJECT_ID}.iam.gserviceaccount.com|g\" /tmp/kf-csb.yaml\n sed -i \"s|\u003cINSTANCE_CONNECTION_NAME\u003e|${CLUSTER_PROJECT_ID}:${COMPUTE_REGION}:${INSTANCE_NAME}|g\" /tmp/kf-csb.yaml\n sed -i \"s|\u003cDB_PORT\u003e|3306|g\" /tmp/kf-csb.yaml\n\n3. Apply yaml for Kf Cloud Service Broker.\n\n kubectl apply -f /tmp/kf-csb.yaml\n\n4. Verify the Kf Cloud Service Broker installation status.\n\n kubectl get pods -n kf-csb\n\nCreate a Service Broker\n-----------------------\n\n**Note:** The user/password must match what you entered in the [Kubernetes secret](#kubernetes_secret) step earlier. \n\n kf create-service-broker cloud-service-broker \u003cvar translate=\"no\"\u003eservicebroker\u003c/var\u003e \u003cvar translate=\"no\"\u003epassword\u003c/var\u003e http://csb-controller.kf-csb/\n\nValidate installation\n---------------------\n\nCheck for available services in the marketplace. \n\n kf marketplace\n\nIf everything is installed and configured correctly, you should see the following: \n\n $ kf marketplace\n\n Broker Name Namespace Description\n cloud-service-broker csb-google-bigquery A fast, economical and fully managed data warehouse for large-scale data analytics.\n cloud-service-broker csb-google-dataproc Dataproc is a fully-managed service for running Apache Spark and Apache Hadoop clusters in a simpler, more cost-efficient way.\n cloud-service-broker csb-google-mysql Mysql is a fully managed service for the Google Cloud Platform.\n cloud-service-broker csb-google-postgres PostgreSQL is a fully managed service for the Google Cloud Platform.\n cloud-service-broker csb-google-redis Cloud Memorystore for Redis is a fully managed Redis service for the Google Cloud Platform.\n cloud-service-broker csb-google-spanner Fully managed, scalable, relational database service for regional and global application data.\n cloud-service-broker csb-google-stackdriver-trace Distributed tracing service\n cloud-service-broker csb-google-storage-bucket Google Cloud Storage that uses the Terraform back-end and grants service accounts IAM permissions directly on the bucket.\n\nWhat's next?\n------------\n\n- Test Kf Cloud Service Broker with our [Spring Music guide](/migrate/kf/docs/2.4/how-to/spring-music).\n\nClean up\n--------\n\n1. Delete cloud-service-broker.\n\n kf delete-service-broker cloud-service-broker\n\n2. Delete CSB components.\n\n kubectl delete ns kf-csb\n\n3. Delete the Kf Cloud Service Broker Cloud SQL for MySQL instance.\n\n ```\n gcloud sql instances delete ${INSTANCE_NAME} --project=${CLUSTER_PROJECT_ID}\n ```\n4. Remove the IAM policy bindings.\n\n ```\n gcloud projects remove-iam-policy-binding ${CLUSTER_PROJECT_ID} \\\n --member='serviceAccount:csb-${CLUSTER_NAME}-sa@${CLUSTER_PROJECT_ID}.iam.gserviceaccount.com' \\\n --role=roles/cloudsql.client\n ``` \n\n ```\n gcloud projects remove-iam-policy-binding ${CLUSTER_PROJECT_ID} \\\n --member='serviceAccount:csb-${CLUSTER_NAME}-sa@${CLUSTER_PROJECT_ID}.iam.gserviceaccount.com' \\\n --role=roles/compute.networkUser\n ``` \n\n ```\n gcloud projects remove-iam-policy-binding ${CLUSTER_PROJECT_ID} \\\n --member='serviceAccount:csb-${CLUSTER_NAME}-sa@${CLUSTER_PROJECT_ID}.iam.gserviceaccount.com' \\\n --role=roles/redis.admin\n ```\n5.
