Elastic Agent environment variables

edit

Elastic Agent environment variables

edit

Use environment variables to configure Elastic Agent when running in a containerized environment. Variables on this page are grouped by action type:

Common variables
edit

To limit the number of environment variables that need to be set, the following common variables are available. These variables can be used across all Elastic Agent actions, but have a lower precedence than action-specific environment variables.

These common variables are useful, for example, when using the same Elasticsearch and Kibana credentials to prepare the Fleet plugin in Kibana, configure Fleet Server, and enroll an Elastic Agent.
