@hchenxa Which version of kustomize are you using? We only support kustomize 1.0 so far.
See https://github.com/kubernetes-sigs/cluster-api-provider-openstack/blob/db10967a3e1b057a35ab738edd0e513bcf6a05f4/README.md#cluster-creation

[jichenjc]

@chrigl seems @hchenxa provided the version as 2.0.3 above...

[chrigl]

Ah thanks @jichenjc ... Haven't seen that. So @hchenxa could you please retest with kustomize 1.0.11?

[hchenxa]

the 1.0.11 worked for me.

@hchenxa Please check if yq is installed or not. Besides, you can also update generate-yaml.sh by adding set -x to get more error messages.
