To update the revision of an existing MultiCloud Image of a HEAD ServerTemplate.
Table of Contents
If you are modifying a ServerTemplate, you may want to update its list of MultiCloud Images. There are two main reasons why you would update a ServerTemplate's MCIs.
To help you know when a newer revision of a MultiCloud Image is available, orange notification balls are displayed. If a newer committed revision of an MCI is available within the RightScale account or in the MultiCloud Marketplace (MCM), a yellow-orange sphere icon will appear next to the MCI under the HEAD ServerTemplate's Images tab.
It's your responsibility to determine whether or not you should update the highlighted MCIs.
Orange ball notifications are only displayed if a newer committed revision of an MCI (with the same lineage) is available. If an MCI is cloned, it's a new object with a different lineage. The diagram below demonstrates the most common user scenarios.
Under the Images tab of a HEAD version of a ServerTemplate, you may see yellow sphere icons, which denote that a newer revision of an MCI is available. RightScale will check within your RightScale account for a newer revision as well as in the MultiCloud Marketplace. The yellow sphere icons are only designed to serve as a notification. If an MCI has a yellow sphere icon, it does not mean that you must update its revision. The spheres will only be displayed for HEAD versions of a ServerTemplate and not committed revisions because only HEAD versions are editable.
If you click on the icon, you will perform a differential (diff) between the current revision and the most recently committed revision that's available. Use the diff to compare the differences between the two revisions to determine whether or not you want to update the MCI to a different revision. In the example below, the differences between the revisions are highlighted for your convenience.
Next, you will need to determine whether or not you want to update the current RightScript revision.
Once you have performed a differential between the two RightScripts and determined that you want to update the revision of a RightScript revision, you can follow one of the upgrade procedures below.
Next, click the "Select Revision" icon . The available revisions will be displayed in a drop-down menu. If the newer revision is not listed in the dropdown menu, you will need to import it from the MultiCloud Marketplace. Select the newer revision that you want to use.
Repeat the steps above to manually update another individual MCI.
The orange ball icon will automatically disappear if you update the ServerTemplate to use the latest committed revision of a MultiCloud Image.
If you make any changes to a ServerTemplate's list of MultiCloud Images, you should test the new images in their respective clouds. A user should be able to successfully launch a server with any of the MCI's images.
Once you have tested the ServerTemplate with the new MCIs, you may want to publish it to the MultiCloud Marketplace so that you can share it with other users.
