#4869 Export /mnt/koji/vol/ on staging Koji through HTTP
Closed: Fixed None Opened 4 years ago by mizdebsk.

= bug description =
Scratch builds on staging Koji submitted by staging Koschei fail with traceback: "HTTPError: HTTP Error 404: Not Found", for example see http://koji.stg.fedoraproject.org/koji/taskinfo?taskID=90001370

= bug analysis =
Koschei runs scratch builds from existing SRPMs, which in most cases are located in production Koji volume at /mnt/koji/vol/prod/. The problem is that this location is not exported through HTTP, so kojid on builders fails with HTTP 404 error.

= fix recommendation =
Either of the following two solutions:

  1. Add rewrite rule to kojiweb.conf
    RewriteRule ^/vol/prod/(.+) https://koji.fedoraproject.org/$1 [R=301,L]
    RewriteRule ^/vol/prod/packages/(.+) https://kojipkgs.fedoraproject.org/packages/$1 [R=301,L]
    Pros: it should be faster - packages will be coming from squid cache at kojipkgs
    Cons: extra hosts entries may need to be added on some staging hosts so that they know how to connect to production koji and kojipkgs

  2. Export contents of vol directory:
    Alias /work "/mnt/koji/vol/"

<directory "="" mnt="" koji="" vol="" "="">
Options Indexes FollowSymLinks
Require all granted
Pros: simple configuration
Cons: data is read directly from production NFS, which apparently is already under high load

I'd vote for option number 2, since it maintains more of the symmetry with the existing setup (i.e., it looks like staging koji has all of the real data). Although, I don't have a good sense of just how loaded our NFS setup is.

Proposed patch for option nr 2 added.
