Upgrade
-------
*Upgrade of Kubernetes Cluster components*: In current implementation of
Kubernetes Cluster deployed by Murano, which uses binaries and hyperkube,
we do not provide a scenario to upgrade Kubernetes Cluster from a previous
version to a newer one. However, we are planning to introduce upgrade
capability in the coming releases of Murano Kubernetes application, by
introducing self-hosted architecture of the Kubernetes Cluster. This will
allow to perform Rolling Update of Kubernetes Cluster itself to the new version.
In current implementation of Kubernetes Cluster deployed by Murano it is not
possible to upgrade Kubernetes Cluster from previous version to newer.
*Framework to Update Murano Kubernetes Application to the new version:*
Currently, Murano doesn't support versioning of application as well as not
having a well-defined framework on how to perform an Upgrade of Murano
Applications. This also affects the possibility to enable Kubernetes Upgrades
via Murano. This is planned to be addressed in the coming release of Murano.
*Rolling updates of application running inside of Kubernetes Cluster:*
The Kubernetes Cluster deployed by Murano supports rolling updates with the
use of “Deployments” and “Replication Controllers (RC)” abstractions.
Please refer to the `Rolling updates`_ section of the Kubernetes application
for more details.
