Upgrading Templates in Containers
To upgrade a application/OS template:
- Select Service Director - Virtuozzo Manager Containers. Choose a Container, click on it and on the opened screen select the Applications tab. On the opened screen there is a list of installed application templates. Please note that templates versions are specified only for non-EZ templates. EZ templates versions are not passed to Parallels Business Automation - Standard and thus, the Version field is filled with zeros for this type of templates.
- Click the Upgrade Applications button above the templates list.
Note: No Upgrade Applications button on the Applications screen means that no upgrades are available.
The set of upgrade options at the screen differs depending on the type of the template:
- For non-EZ templates.
- Choose the template(s) you wish to upgrade, select the target version in the New version drop-down menu. The template current version is provided under the Current version heading.
- To ignore any dependencies for the upgrade installation, check the Force upgrade box. To suspend upgrade in case a new version is not compatible with the existing applications clear this box.
- Jump over several upgrades instead of adding them sequentially. This is the Virtuozzo option
force jump
used to skip application previous versions (if any) when upgrading an application to a given version. For example, you want to upgrade an application to a newer version. But the version you want to upgrade to is not the next in respect to a current one, i.e., some other versions of this application were released (and are available) before the newest version. Probably it is better to install previous upgrades and then upgrade an application to the newest version, but if you are sure that it is safe to install the latest upgrade, you can enable the jump option for this application. - To start upgrade, click the Upgrade button.
- For EZ templates.
- Check the boxes next to the names of templates you wish to upgrade and click the Test Upgrade button under the template properties to check for available upgrades. After the check is complete, you will see a message telling you about the possible upgrades.
- The Force upgrade option works in the same way as for non-EZ templates (see above).
- Use packages cached locally on Hardware Node. Check this box to install upgrade from the RPMs repository located on a Hardware Node that hosts the Container.
- Press Upgrade to initiate the upgrade operation.
You can start upgrading to the latest versions straight away, without prior testing. In this case the system will check for newer RPM packages in the repository and upgrade to them if there are any. If there are no newer versions, the upgrade will not take place. You can also effect the upgrade on the template properties page. To do this click on the template you wish to upgrade in the templates list, on the opened screen press Test Upgrade and if there are available upgrades click on Upgrade.
Note: It is recommended that you do mass upgrade on the Applications page rather than an independent update for a separate template as the system is in this case less prompt to errors and besides you are able to upgrade your OS template among other templates.
