NS8 has an HTTP API, so it is possible to write a Bash script that updates multiple clusters, if desired.
However, applying updates blindly is bad practice. As mentioned in other threads:
- Nethbot will notify the forum about NS8 updates, just like it does for NS7.
- The Software Center will display a link to the release information or show the release changelog directly.
- Automatic updates are already available if a subscription is active.
