As software updates become available, the Dashboard is able to perform the update procedure for you, and update the components on each node. To do this:
The system will search for updates and perform any required actions automatically. The process can take a while, depending on cluster size, but will continue even if the page is left or refreshed. Revisiting the page will show the current progress. The log will show you what step the system is currently on. Once the update is complete, refresh the page and accept the new SSL certificate warning (if shown).
