IP whitelist (FREE SELF)

GitLab provides some monitoring endpoints that provide health check information when probed.

To control access to those endpoints via IP whitelisting, you can add single hosts or use IP ranges:

::Tabs

:::TabTitle Linux package (Omnibus)

Open /etc/gitlab/gitlab.rb and add or uncomment the following:

gitlab_rails['monitoring_whitelist'] = ['127.0.0.0/8', '192.168.0.1']

:::TabTitle Helm chart (Kubernetes)

You can set the required IPs under the gitlab.webservice.monitoring.ipWhitelist key. For example:

gitlab:
   webservice:
      monitoring:
         # Monitoring IP whitelist
         ipWhitelist:
         - 0.0.0.0/0 # Default

:::TabTitle Self-compiled (source)

Edit config/gitlab.yml:

monitoring:
  # by default only local IPs are allowed to access monitoring resources
  ip_whitelist:
    - 127.0.0.0/8
    - 192.168.0.1

::EndTabs
