Esegui il deployment del service broker Kf Cloud

Questa pagina mostra come eseguire il deployment di Cloud Service Broker Kf per Google Cloud e utilizzarlo per eseguire il provisioning o il deprovisioning delle risorse di supporto. Per saperne di più su Kf Cloud Service Broker, consulta i concetti e l'architettura.

Creare variabili di ambiente

Linux

export PROJECT_ID=YOUR_PROJECT_ID
export CLUSTER_PROJECT_ID=YOUR_PROJECT_ID
export CLUSTER_NAME=kf-cluster
export INSTANCE_NAME=cloud-service-broker
export COMPUTE_REGION=us-central1

Windows PowerShell

Set-Variable -Name PROJECT_ID -Value YOUR_PROJECT_ID
Set-Variable -Name CLUSTER_PROJECT_ID -Value YOUR_PROJECT_ID
Set-Variable -Name CLUSTER_NAME -Value kf-cluster
Set-Variable -Name INSTANCE_NAME -Value cloud-service-broker
Set-Variable -Name COMPUTE_REGION -Value us-central1

configura il database Kf Cloud Service Broker

  1. Crea un'istanza Cloud SQL per MySQL.

    gcloud sql instances create ${INSTANCE_NAME} --cpu=2 --memory=7680MB --require-ssl --region=${COMPUTE_REGION}
  2. Crea un database denominato servicebroker nell'istanza Cloud SQL per MySQL.

    gcloud sql databases create servicebroker -i ${INSTANCE_NAME}
  3. Crea un nome utente e una password da utilizzare da Cloud Service Broker Kf.

    gcloud sql users create csbuser -i ${INSTANCE_NAME} --password=csbpassword

Configurare un account di servizio Google (GSA) per il service broker Kf Cloud

  1. Crea un account di servizio Google.

    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}"
  2. Concedi le autorizzazioni roles/cloudsql.client all'account di servizio. Questo è necessario per connettere il pod Kf Cloud Service Broker all'istanza Cloud SQL per MySQL tramite il proxy di autenticazione Cloud SQL.

    gcloud projects add-iam-policy-binding ${CLUSTER_PROJECT_ID} \
      --member="serviceAccount:csb-${CLUSTER_NAME}-sa@${CLUSTER_PROJECT_ID}.iam.gserviceaccount.com" \
      --role="roles/cloudsql.client"
  3. Concedi autorizzazioni Google Cloud aggiuntive all'account di servizio.

    gcloud projects add-iam-policy-binding ${CLUSTER_PROJECT_ID} \
      --member="serviceAccount:csb-${CLUSTER_NAME}-sa@${CLUSTER_PROJECT_ID}.iam.gserviceaccount.com" \
      --role="roles/compute.networkUser"
    gcloud projects add-iam-policy-binding ${CLUSTER_PROJECT_ID} \
      --member="serviceAccount:csb-${CLUSTER_NAME}-sa@${CLUSTER_PROJECT_ID}.iam.gserviceaccount.com" \
      --role="roles/cloudsql.admin"
    gcloud projects add-iam-policy-binding ${CLUSTER_PROJECT_ID} \
      --member="serviceAccount:csb-${CLUSTER_NAME}-sa@${CLUSTER_PROJECT_ID}.iam.gserviceaccount.com" \
      --role="roles/redis.admin"
  4. Verifica le autorizzazioni.

    gcloud projects get-iam-policy ${CLUSTER_PROJECT_ID} \
      --filter='bindings.members:serviceAccount:"CSB_SERVICE_ACCOUNT_NAME"' \
      --flatten="bindings[].members"

Configurazione di Workload Identity per il service broker Kf Cloud

  1. Associa l'account di servizio Google all'account di servizio Kubernetes.

    gcloud iam service-accounts add-iam-policy-binding "csb-${CLUSTER_NAME}-sa@${CLUSTER_PROJECT_ID}.iam.gserviceaccount.com" \
      --project=${CLUSTER_PROJECT_ID} \
      --role="roles/iam.workloadIdentityUser" \
      --member="serviceAccount:${CLUSTER_PROJECT_ID}.svc.id.goog[kf-csb/csb-user]"
  2. Verifica il vincolo.

    gcloud iam service-accounts get-iam-policy "csb-${CLUSTER_NAME}-sa@${CLUSTER_PROJECT_ID}.iam.gserviceaccount.com" \
      --project=${CLUSTER_PROJECT_ID}

Configura un secret Kubernetes per condividere la configurazione con Cloud Service Broker Kf

  1. Crea un file config.yml.

    cat << EOF >> ./config.yml
    gcp:
      credentials: ""
      project: ${CLUSTER_PROJECT_ID}
    db:
      host: 127.0.0.1
      password: csbpassword
      user: csbuser
      tls: false
    api:
      user: servicebroker
      password: password
    EOF
  2. Crea lo spazio dei nomi kf-csb.

    kubectl create ns kf-csb
  3. Crea il secret di Kubernetes.

    kubectl create secret generic csb-secret --from-file=config.yml -n kf-csb

Installare Kf Cloud Service Broker

  1. Scarica il kf-csb.yml.

    gcloud storage cp gs://kf-releases/csb/v1.0.0/kf-csb.yaml /tmp/kf-csb.yaml
  2. Modifica /tmp/kf-csb.yaml e sostituisci i segnaposto con i valori finali. Nell'esempio seguente viene utilizzato sed.

    sed -i "s|<GSA_NAME>|csb-${CLUSTER_NAME}-sa@${CLUSTER_PROJECT_ID}.iam.gserviceaccount.com|g" /tmp/kf-csb.yaml
    sed -i "s|<INSTANCE_CONNECTION_NAME>|${CLUSTER_PROJECT_ID}:${COMPUTE_REGION}:${INSTANCE_NAME}|g" /tmp/kf-csb.yaml
    sed -i "s|<DB_PORT>|3306|g" /tmp/kf-csb.yaml
  3. Applica YAML per Kf Cloud Service Broker.

    kubectl apply -f /tmp/kf-csb.yaml
  4. Verifica lo stato di installazione di Cloud Service Broker Kf.

    kubectl get pods -n kf-csb

Creare un Service Broker

  kf create-service-broker cloud-service-broker servicebroker password http://csb-controller.kf-csb/

Convalida l'installazione
