We added initial support for a kubectl fdb plugin to work with. The plugin can be found in the official FDB operator repo: https://github.com/FoundationDB/fdb-kubernetes-operator/tree/master/kubectl-fdb. There are already some additional ideas what functionality we want to have in the plugin. If you have some additional features you think are useful or you want to see in the plugin feel free to open an GitHub issue and/or implement the feature.
Looking forward to hear from you!
