+# Integrating with Confluent Cloud 
+
+DataHub provides the ability to easily leverage Confluent Cloud as your Kafka provider. To do so, you'll need to configure DataHub to talk to a broker and schema registry hosted by Confluent.
+
+Doing this is a matter of configuring the Kafka Producer and Consumers used by DataHub correctly. There are 2 places where Kafka configuration should be provided: the metadata server (GMS) and the frontend server (datahub-frontend). Follow the steps below to configure these components for your deployment.
+
+## **Step 1: Create topics in Confluent Control Center**
+
+First, you'll need to create 4 new topics in the [Confluent Control Center](https://docs.confluent.io/platform/current/control-center/index.html). By default they have the following names:
+
+1. **MetadataChangeEvent_v4**: Metadata change proposal messages
+2. **MetadataAuditEvent_v4**: Metadata change log messages 
+3. **FailedMetadataChangeEvent_v4**: Failed to process #1 event
+4. **DataHubUsageEvent_v1**: User behavior tracking event for UI
+
+To do so, navigate to your **Cluster** and click "Create Topic". Feel free to tweak the default topic configurations to
+match your preferences.
+
+![CreateTopic](../imgs/confluent-create-topic.png)
+
+## Step 2: Configure DataHub Container to use Confluent Cloud Topics
+
+### Docker Compose
+
+If you are deploying DataHub via docker compose, enabling connection to Confluent is a matter of a) creating topics in the Confluent Control Center and b) changing the default container environment variables.
+
+First, configure GMS to connect to Confluent Cloud by changing `docker/gms/env/docker.env`:
+
+```
+KAFKA_BOOTSTRAP_SERVER=pkc-g4ml2.eu-west-2.aws.confluent.cloud:9092
+KAFKA_SCHEMAREGISTRY_URL=https://plrm-qwlpp.us-east-2.aws.confluent.cloud
+
+# Confluent Cloud Configs
+SPRING_KAFKA_PROPERTIES_SECURITY_PROTOCOL=SASL_SSL
+SPRING_KAFKA_PROPERTIES_SASL_JAAS_CONFIG=org.apache.kafka.common.security.plain.PlainLoginModule   required username='XFA45EL1QFUQP4PA' password='ltyf96EvR1YYutsjLB3ZYfrk+yfCXD8sQHCE3EMp57A2jNs4RR7J1bU9k6lM6rU';
+SPRING_KAFKA_PROPERTIES_SASL_MECHANISM=PLAIN
+SPRING_KAFKA_PROPERTIES_CLIENT_DNS_LOOKUP=use_all_dns_ips
+SPRING_KAFKA_PROPERTIES_BASIC_AUTH_CREDENTIALS_SOURCE=USER_INFO
+SPRING_KAFKA_PROPERTIES_BASIC_AUTH_USER_INFO=P2ETAN5QR2LCWL14:RTjqw7AfETDl0RZo/7R0123LhPYs2TGjFKmvMWUFnlJ3uKubFbB1Sfs7aOjjNi1m23
+```
+
+Next, configure datahub-frontend to connect to Confluent Cloud by changing `docker/datahub-frontend/env/docker.env`:
+
+```
+KAFKA_BOOTSTRAP_SERVER=pkc-g4ml2.eu-west-2.aws.confluent.cloud:9092
+
+# Confluent Cloud Configs
+KAFKA_PROPERTIES_SECURITY_PROTOCOL=SASL_SSL
+KAFKA_PROPERTIES_SASL_JAAS_CONFIG=org.apache.kafka.common.security.plain.PlainLoginModule   required username='XFA45EL1QFUQP4PA' password='ltyf96EvR1YYutsjLB3ZYfrk+yfCXD8sQHCE3EMp57A2jNs4RR7J1bU9k6lM6rU';
+KAFKA_PROPERTIES_SASL_MECHANISM=PLAIN
+KAFKA_PROPERTIES_CLIENT_DNS_LOOKUP=use_all_dns_ips
+KAFKA_PROPERTIES_BASIC_AUTH_CREDENTIALS_SOURCE=USER_INFO
+KAFKA_PROPERTIES_BASIC_AUTH_USER_INFO=P2ETAN5QR2LCWL14:RTjqw7AfETDl0RZo/7R0123LhPYs2TGjFKmvMWUFnlJ3uKubFbB1Sfs7aOjjNi1m23
+```
+
+Note that this step is only required if DATAHUB_ANALYTICS_ENABLED is not set to false.
+
+If you're deploying with Docker Compose, you do not need to deploy the Zookeeper, Kafka Broker, or Schema Registry containers that ship by default.
+
+### Helm
+
+If you're deploying to K8s using Helm, you can simply change the `datahub-helm` values.yml to point to Confluent Cloud and disable some default containers:
+
+First, disable the `cp-schema-registry` service:
+
+```
+cp-schema-registry:
+  enabled: false 
+```
+
+Next, disable the `kafkaSetupJob` service:
+
+```
+kafkaSetupJob:
+    enabled: false
+```
+
+Then, update the `kafka` configurations to point to your Confluent Cloud broker and schema registry instance, along with the topics you've created in Step 1:
+
+```
+kafka:
+      bootstrap:
+        server: pkc-g4ml2.eu-west-2.aws.confluent.cloud:9092
+      schemaregistry:
+        url: https://plrm-qwlpp.us-east-2.aws.confluent.cloud
+```
+
+Next, you'll want to create 2 new Kubernetes secrets, one for the JaaS configuration which contains the username and password for Confluent,
+and another for the user info used for connecting to the schema registry. You'll find the values for each within the Confluent Control Center. Specifically,
+select "Clients" -> "Configure new Java Client". You should see a page like the following:
+
+
+![Config](../imgs/confluent-cloud-config.png)
+
+You'll want to generate both a Kafka Cluster API Key & a Schema Registry key. Once you do so,you should see the config
+automatically populate with your new secrets:
+
+![Config](../imgs/confluent-cloud-config-2.png)
+
+You'll need to copy the values of `sasl.jaas.config` and `basic.auth.user.info`
+for the next step.
+
+The next step is to create K8s secrets containing the config values you've just generated. Specifically, you'll run the following commands:
+
+```shell
+kubectl create secret generic confluent-secrets --from-literal=sasl_jaas_config="<your-sasl.jaas.config>"
+kubectl create secret generic confluent-secrets --from-literal=basic_auth_user_info="<your-basic.auth.user.info>"
+```
+
+With your config values substituted as appropriate. For example, in our case we'd run:
+
+```shell
+kubectl create secret generic confluent-secrets --from-literal=sasl_jaas_config="org.apache.kafka.common.security.plain.PlainLoginModule   required username='XFA45EL1QFUQP4PA' password='ltyf96EvR1YYutsjLB3ZYfrk+yfCXD8sQHCE3EMp57A2jNs4RR7J1bU9k6lM6rU';"
+kubectl create secret generic confluent-secrets --from-literal=basic_auth_user_info="P2ETAN5QR2LCWL14:RTjqw7AfETDl0RZo/7R0123LhPYs2TGjFKmvMWUFnlJ3uKubFbB1Sfs7aOjjNi1m23"
+```
+
+Finally, we'll configure our containers to pick up the Confluent Kafka Configs by changing two config blocks in our values.yaml file. You
+should see these blocks commented at the bottom of the template. You'll want to uncomment them and set them to the following values: 
+
+```
+credentialsAndCertsSecrets:
+  name: confluent-secrets
+  secureEnv:
+    sasl.jaas.config: sasl_jaas_config
+    basic.auth.user.info: basic_auth_user_info
+
+
+springKafkaConfigurationOverrides:
+      security.protocol: SASL
+      sasl.mechanism: PLAIN
+      client.dns.lookup: use_all_dns_ips
+      basic.auth.credentials.source: USER_INFO
+```
+
+Then simply apply the updated `values.yaml` to your K8s cluster via `kubectl apply`. 
+
+## Contribution
+Accepting contributions for a setup script compatible with Confluent Cloud!
+
+Currently the kafka-setup-job container we ship with is only compatible with a distribution of Kafka wherein ZooKeeper
+is exposed and available. A version of the job using the [Confluent CLI](https://docs.confluent.io/confluent-cli/current/command-reference/kafka/topic/confluent_kafka_topic_create.html) 
+would be very useful for the broader community.
