How to Create Linux Images

How to create a VCL Linux image environment.

  1. Select "Make a Reservation" from the main VCL site.
     
  2. Select "Manage Images"
     
  3. Select "Create / Update an Image" -> submit
     
  4. From the pull-down menu, select the base image you would like to start with
     
  5. select the Now button
     
  6. click Create Imaging Reservation
     
  7. If the image you have choosen is preloaded wait time will be less than a minute, else you may wait 10-15 minutes while the remote node is being loaded.
     
  8. click the "Connect" button when it appears. Information on how to connect will be displayed
     
  9. Use sudo bash to get a root shell.

  10. You'll have a set amount of time, usually 12 hours, to complete before the reservation expires and the node is wiped clean.
     
  11. To start the imaging process, revisit the VCL site and select Current Reservations.
     
  12. Select the "Create Image" button
     
  13. Enter an image name.  Something simple related to the applications you installed is fine. The image name is displayed when a user makes a reservation and can be changed later if needed.
     
  14. The minimum specs can be left at the defaults
     
  15. click submit and then confirm your settings.
     
  16. After about 20-25 minutes, you will receive an email saying your image ready for testing when the image creation process is done (occasionally, if there is a lot of software installed in the image or if the system is extremely busy, this can take as long as 90 minutes).
