In addition to these pluggable add-ons, you can specify an add-on that you want deployed after the cluster deployment is complete.
As of v0.1.8, RKE will update an add-on if it is the same name.
As of version v0.1.7, add-ons are split into two categories:
- Critical add-ons: If these add-ons fail to deploy for any reason, RKE will error out.
- Non-critical add-ons: If these add-ons fail to deploy, RKE will only log a warning and continue deploying any other add-ons.Currently, only the network plug-in is considered critical. KubeDNS, and user-defined add-ons are considered non-critical.
