Ceph » mgr » Dashboard

If you set a URL prefix for the Ceph dashboard, the default login page will not load unless the requested URL contains a forward slash at the end.

Environment¶

• ceph version string: Confirmed issue exists with 15.2.4, test builds of 15.2.7 and 16.0.0
• Platform (OS/distro/release): All platforms affected, but tested on Linux
• Cluster details (nodes, monitors, OSDs): Tested with 3 node rook based cluster in Kubernetes and a local devel cluster using make vstart
• Browser used (e.g.: Version 86.0.4240.198 (Official Build) (64-bit)): Tested with Chrome 87.0.4280.88 (Official Build) (x86_64)

How reproducible¶

1) Set a dashboard URL prefix:

$ ceph config set mgr mgr/dashboard/url_prefix /ceph

2) Visit dashboard url without a forward slash at the end:

https://localhost:41409/ceph

Actual results¶

Instead of the login page, an 404 error message in json is displayed:

{"status": "404 Not Found", "detail": "The path '/ceph' was not found.", "request_id": "da796597-e50e-4994-987b-c19c34934623"}

However, if you add a forward slash to the end, the login page loads correctly.

https://localhost:41409/ceph/

Expected results¶

The login page should be shown regardless of the presence of a forward slash at the end of the URL.
