Lenses requires two configuration files
This file contains the main configuration options, such as the connection details for your brokers, or the port Lenses uses. You have to create this file before Lenses can work. For a complete list of configuration options please refer to Options reference .
security.conf contains sensitive authentication configuration options.
The Lenses docker image and helm charts create these files automatically at start up.
A quick start example of
lenses.conf looks like:
lenses.ip = 0.0.0.0 lenses.port = 9991 # License file lenses.license.file = "/etc/lenses/license.json" # Directory for local storage (write access needed) - preserve between upgrades lenses.storage.directory = "/var/lib/lenses/storage" # Bootstrap brokers lenses.kafka.brokers = "PLAINTEXT://host1:9092,PLAINTEXT://host2:9092,PLAINTEXT://host3:9092"
A quick start example
security.conf looks like:
# A single admin user lenses.security.user = "admin" lenses.security.password = "admin"
# Relative or absolute path for a readable license file lenses.license.file = "license.json"
A license can be updated via the Lenses CLI following this command:
$ lenses-cli license update ./lenses.lic
The user applying the change, requires Manage License permission set up in Lenses.
Lenses will store its internal state in the
storage folder. We advise to explicitly
set this location, ensure the Lenses process has permission to read and write files in this
directory and have an upgrade and backup policy in place.
lenses.storage.directory = "/path/to/persistent/data/directory"
