Using the GitLab-Exporter chart

The gitlab-exporter sub-chart provides Prometheus metrics for GitLab application-specific data. It talks to PostgreSQL directly to perform queries to retrieve data for CI builds, pull mirrors, etc. In addition, it uses the Sidekiq API, which talks to Redis to gather different metrics around the state of the Sidekiq queues (e.g. number of jobs).


This chart depends on Redis and PostgreSQL services, either as part of the complete GitLab chart or provided as external services reachable from the Kubernetes cluster on which this chart is deployed.


The gitlab-exporter chart is configured as follows: Global Settings and Chart Settings.

Chart configuration examples


pullSecrets allows you to authenticate to a private registry to pull images for a pod.

Additional details about private registries and their authentication methods can be found in the Kubernetes documentation.

Below is an example use of pullSecrets:

  repository: my.unicorn.repository
  pullPolicy: Always
  - name: my-secret-name
  - name: my-secondary-secret-name


annotations allows you to add annotations to the GitLab Exporter pods. For example:

annotations: annotation-value

Global Settings

We share some common global settings among our charts. See the Globals Documentation for common configuration options, such as GitLab and Registry hostnames.

Chart Settings

The following values are used to configure the GitLab Exporter pod.


By default, the pod exposes a metrics endpoint at /metrics. When metrics are enabled, annotations are added to each pod allowing a Prometheus server to discover and scrape the exposed metrics.
