When sending data to a secured cluster through the
output, Functionbeat must either provide basic authentication credentials
or present a client certificate.
Before you begin: Grant users access to secured resources.
You specify authentication credentials in the Functionbeat configuration file:
To use basic authentication, specify the
output.elasticsearch. For example:
Let’s assume this user has the privileges required to publish events to Elasticsearch.
The example shows a hard-coded password, but you should store sensitive values in the secrets keystore.
If you’ve configured the Kibana endpoint, also specify credentials for authenticating with Kibana. For example:
To use Public Key Infrastructure (PKI) certificates to authenticate users, configure the
keysettings. These settings assume that the distinguished name (DN) in the certificate is mapped to the appropriate roles in the
role_mapping.ymlfile on each node in the Elasticsearch cluster. For more information, see Using Role Mapping Files.
output.elasticsearch: hosts: ["localhost:9200"] ssl.certificate: "/etc/pki/client/cert.pem" ssl.key: "/etc/pki/client/cert.key"
