how to upgrade ressources from a node without restarting it (open stack)

agahkarakuzu commented 5 years ago

I was doing some reading about K8 and remember that this post was talking about strategies to upgrade a node without downtime. This somewhat remains low level to what we may need to deal with tho.

By upgrading resources, if you mean switching to the latest available version of the BinderHub made available in Helm, I don't know if a similar zero downtown strategy is inherently adopted in the case of Helm.

To upgrade to the latest revision, this can be done pretty easily without shutting down the servers. I am talking about changing the ressources via a command line on the server, without shutting it down. Because now I allocated some ressources quite randomly (based on our ressources and this post).

something like : openstack add-node 1

Related to #7 too. This issue will become more of a priority as we get more users.
