In most cases, the ingestion to Kloudfuse data plane from various telemetry agents/collectors is secure (encrypted) due to using HTTPS (TLS) which provides transport layer encryption. More on the TLS handshake conducted between the clients and the server can be found online. This documentation explains how to add authentication to the ingestion in addition to confidentiality provided by HTTPS.

Kloudfuse supports many telemetry agents (choose the steps which are relevant to the agent you are using). To enable authentication for ingestion, follow these steps.

Step 1. Generate AUTH_TOKEN

Generate an auth token (referred to as AUTH_TOKEN) and store this value in a safe location. You will need to use this later in more than one place.

AUTH_TOKEN=`cat /dev/urandom | env LC_ALL=C tr -dc 'a-zA-Z0-9' | fold -w 32 | head -n 1`

Base64 encode the AUTH_TOKEN (referred to as AUTH_TOKEN_ENCODED ) 

AUTH_TOKEN_ENCODED=`echo -n $AUTH_TOKEN | base64`

Step 2. Configure Telemetry agents/sources

Prometheus Remote Write

Update prometheus remote write configuration as shown below:

    prometheus.yml:
      remote_write:
      - url: https://<customer>.kloudfuse.io/ingester/write
        authorization:
          credentials: <AUTH_TOKEN>

Fluent Bit

Update/Add the following Headers field with AUTH_TOKEN replaced with the one generated in step 1, in the HTTP plugin section of the fluent-bit configuration file as shown below:

    [OUTPUT]
        Name http
        Match <match_pattern>
        Host <kfuse_ingress_ip>
        Port 443
        TLS on
        URI /ingester/v1/fluent_bit
        Headers Kf-Api-Key <AUTH_TOKEN>

DD/Kfuse agent

Update/Add the dd-agent configuration file to add the AUTH_TOKEN as the apiKey as shown below:

datadog:
  apiKey: <AUTH_TOKEN>
  ...

AWS CloudWatch metrics & Logs (Kinesis)

When configuring kinesis firehose data stream to send logs/metrics from Cloudwatch, use the AUTH_TOKEN value generated in step 1 as the access token. If the firehose data stream is already setup, then update it to use AUTH_TOKEN value as access token.

AWS Eventbridge Events

When configuring Eventbridge to ingest to Kloudfuse, use AUTH_TOKEN as the value for the Kf_Api_Key.

Step 3: Configure kfuse

Use the base64 encoded value of the AUTH_TOKEN (AUTH_TOKEN_ENCODED) and create a kubernetes secret with the name kfuse-auth-ingest:

apiVersion: v1
kind: Secret
metadata:  
  name: kfuse-auth-ingest
type: Opaque
data:
  authToken: <AUTH_TOKEN_ENCODED>

Update the custom-values.yaml file to include following in the ingester config section:

ingester:
  config:
    authConfig:
      enabled: true
  • No labels
