When the Agent runs as a container, it tries by default to Autodiscover other containers around it based on default Autodiscovery configuration files named auto_conf.yaml. You can find these files in the corresponding conf.d/<INTEGRATION>.d/ folders for the following integrations:
The auto_conf.yaml configuration files cover all required parameters to set up a specific integration, with their corresponding Autodiscovery Templates Variables in place to take into account the containerized environment.
The auto configuration logic only supports the default configuration for any integration above. If you want to customize your Datadog integration configuration, see the Integrations Templates documentation to learn how to configure your Agent Autodiscovery. Any configuration discovered through Kubernetes Annotations or Docker Labels for a given container takes precedence over the auto_conf.yaml file.
To disable the Agent from using the auto_conf.yaml configuration you can add the environment variable DD_IGNORE_AUTOCONF for the desired integration(s) to disable. The environment variable:
DD_IGNORE_AUTOCONF="redisdb istio"
would have the Agent ignore the redisdb.d/auto_conf.yaml and istio.d/auto_conf.yaml file and avoid automatically setting up these integrations.
