Centos VEGL Snapshot

Current Snapshot

For the past, images have been created in NCI/NeCTAR for VGL Portal. Things had changed since NeCTAR loaded a new CentOS 6.5 x86_64 image, instance created based on this image doesn't have aki_id and ari_id anymore and thus the command used to create image as specified in VGLSingleJobImage has become obsolete.

The following steps are the normal and easiest way suggested by technical support team from NeCTAR to create snapshot for VGL:
  1. choose an existing NeCATR public image as a base image,
  2. launch an instance from it and log in
  3. make necessary changes accordingly
  4. and then make a snapshot of the instance
  5. future changes, boot new instances from the snapshot (you changes will be in that snapshot)

Choosing image and create new instance:

From nectar dashboard:
  • choose the GeophysicsVL project
  • go to Images & Snapshot from the left menu
  • chose the NeCTAR offical tab from the top menu
  • select the image you want from the list
  • create a new instance based on the selected image

Note: Ensure that you have registered your public key on your user account from the access and security menu on the left so that when you create the instance from the image, you can select the keypair to use for ssh.

Setting up new intance for AEM Inversion

Install Puppet and VGL custom modules:

yum install -y wget
wget https://svn.auscope.org/subversion/AuScopePortal/VEGL-Portal/trunk/vm/puppet/installPuppet-centos.sh
chmod +x installPuppet-centos.sh

Install modules required by AEM Inversion

wget https://svn.auscope.org/subversion/AuScopePortal/VEGL-Portal/trunk/vm/puppet/aem.pp
puppet apply aem.pp

Note: Until the paperwork to make GA AEM code public, the AEM code provided from GA will have to be intalled and build manually - refer to JIRA task VGL-161.

Creating new snapshot from the new instance

From nectar dashboard, goto Instances on the left menu. Select the instance which you want to create a new snapshot and click the Create Snapshot button at the far right. Enter the new snapshot name and click Create Snapshot button. The newly created snapshot will be listed under Images & Snapshots page.
