Create Fluentd Certificate

To create an SSL certificate for the splunk-forwarder use this command and answer the questions like in the example below.

export INSTANCE_NAME=splunk-forwarder-customer-a (1)
openssl req  -nodes -new -x509 -days 3650 -keyout server.key -out server.cert -subj /name=${INSTANCE_NAME}.openshift-logging.svc

1	Set `INSTANCE_NAME` to the name you’re instantiating the component with.

Upload Private Key to Vault

Create or update the secret in Vault.

You need to be logged in to Vault for the commands to work.

# Adjust to your environment
instance=#INSTANCE_NAME
key="clusters/kv/${TENANT_ID}/${CLUSTER_ID}/openshift4-splunk-forwarder/${instance}/fluentd"

# Query for existing secrets first
vault kv get "${key}"

# If there are existing secrets, add your instance secrets:
vault kv patch "${key}" privatekey=$(cat server.key)

# If there is no pre-existing secret, create new:
vault kv put "${key}" privatekey=$(cat server.key)
