Instance group configuration update
On public image-based VMs, the OS and software are not updated automatically. You can update them on your own.
To do this:
- Describe the appropriate instance template.
- Set the desired deployment policy.
- Run the update operation for the group.
Update with group degradation
Sequential updates of instances in a group.
For example, to update a group by taking one instance out of service at a time, set the following parameters in the
... deploy-policy: max_unavailable: 1 max_expansion: 0 ... ...
Update with additional resources allocated
Update by creating instances with a new configuration. As you add instances with a new configuration to the group, those with the old configuration are deleted.
For example, to update one group instance at a time, set the following parameters in the
... deploy-policy: max_unavailable = 0 max_expansion = 1 ... ...
