SSL example

Implement ssl for kafbat-ui

To implement SSL for kafbat-ui you need to provide JKS files into the pod. Here is the instruction on how to do that.

Create config map with content from kafka.truststore.jks and kafka.keystore.jks.

To create configmap use following command.

kubectl create configmap ssl-files --from-file=kafka.truststore.jks --from-file=kafka.keystore.jks

If you have specified namespace use command.

kubectl create configmap ssl-files --from-file=kafka.truststore.jks --from-file=kafka.keystore.jks -n {{namespace}

Create secret.

Encode secret with base64(You can use this tool (https://www.base64encode.org/). Create secret.yaml file with the following content

apiVersion: v1
kind: Secret
metadata:
 name: ssl-secret
 # Specify namespace if needed, uncomment next line and provide namespace
 #namespace: {namespace}
type: Opaque
data:
 KAFKA_CLUSTERS_0_PROPERTIES_SSL_TRUSTSTORE_PASSWORD: ##Base 64 encoded secret
 KAFKA_CLUSTERS_0_PROPERTIES_SSL_KEYSTORE_PASSWORD: ##Base 64 encoded secret

Create ssl-values.yaml file with the following content.

existingSecret: "ssl-secret"


env:
- name:  KAFKA_CLUSTERS_0_PROPERTIES_SSL_TRUSTSTORE_LOCATION 
  value:  /ssl/kafka.truststore.jks
- name: KAFKA_CLUSTERS_0_PROPERTIES_SSL_KEYSTORE_LOCATION
  value: /ssl/kafka.keystore.jks


volumeMounts:
 - name: config-volume
   mountPath: /ssl

volumes:
 - name: config-volume
   configMap:
     name: ssl-files

Install chart with command

helm install kafbat-ui kafbat-ui/helm-charts -f ssl-values.yaml

If you have specified namespace for configmap and secret please use this command

helm install kafbat-ui kafbat-ui/helm-charts -f ssl-values.yaml -n {namespace}
