FOG is in use in the Sepia lab. It enables us to reimage baremetal testnodes before every job.

Our instance is currently hosted at http://fog.front.sepia.ceph.com/fog.

Username: fog
Password: Standard root password

This can be done manually by basically deciphering the bash monster in https://github.com/ceph/ceph-build/tree/master/sepia-fog-images

1. Navigate to https://jenkins.ceph.com/job/sepia-fog-images/build?delay=0sec
2. Choose which machine types and distros you want to capture images for
3. Click Build
4. …
5. Profit

If capturing any image fails, the job is configured to cancel the OS capture and will leave the testnodes locked so you can debug/investigate.

1. Update the friendly distro names in the parameters dictionary in sepia-fog-images.yml
2. Update the Cobbler and FOG image names at the top of the build script
3. Create an Image in FOG for each machine type
   1. Navigate to http://fog.front.sepia.ceph.com/fog/management/index.php?node=image
   2. Click Create New Image
   3. Set Image Name to MACHINETYPE_DISTRO_DISTROVERSION. (e.g., mira_centos_7.5)
   4. Set Image Path to the image's name (e.g., /images/mira_centos_7.5)
   5. Set Operating System to Linux (I'd hope)
   6. Click Add
   7. Repeat for each machine type!
