Fluxcd cli autocomplete kubernetes

Question

Is it possible to have the fluxcd cli autocomplete information from the cluster in the current context, similar to how kubectl or helm does?

While flux does provide cli completion via flux completion SHELL, this is only for the flux components for commands. For instance

flux reconcile hr -n some_namespace_start TAB

does not produce a suggestion on namespace. Similar issue with resource name, eg:

flux reconcile hr BEGIN_SOME_HR_NAME TAB

does not provide suggestions for helm releases in the flux-system namespace for instance.

Answer 1

The auto-complete does provide completion of information from the Kubernetes cluster.

Did you load the feature as per the official documentation?

To load completion run

. <(flux completion bash)

To configure your bash shell to load completions for each session add to your bashrc

# ~/.bashrc or ~/.profile
command -v flux >/dev/null && . <(flux completion bash)
