VariablePUBLIC_URL
DescriptionPUBLIC_URL Environment Variable

The PUBLIC_URL is the URL where the Humio instance is reachable from a browser. Trailing slashes in the URL are discarded.

This property is only important if you plan to use OAuth Federated Login, Auth0 Login, or if you want to be able to have messages from Actions have consistent links back to the Humio User Interface. For the latter, you can also use ACTION_LINK_BASE_URL.

PUBLIC_URL=https://humio.mycompany.com

Users or browsers will use this URL to reach the server. It's used to create links to the server. It's important to set this property when using OAuth authentication or alerts.

It's not a problem if the URL is only reachable behind a VPN, as the user's browser can still access it.
