HNC v0.9.0-rc1 includes many minor fixes for object propagation and cluster control.

Installing

WARNING: if your cluster already has HNC installed, please ensure you are using HNC v0.8.0 or later.

You can install or upgrade HNC on your cluster using the following commands (admin privileges required):

# Select the latest version of HNC
HNC_VERSION=v0.9.0-rc1

# Install HNC. Afterwards, wait up to 30s for HNC to refresh the certificates on its webhooks.
kubectl apply -f https://github.com/kubernetes-sigs/hierarchical-namespaces/releases/download/${HNC_VERSION}/hnc-manager.yaml 

To install the kubectl plugin on your workstation, either use Krew or install manually:

• Via Krew: Install Krew if you don't have it already, then run the command kubectl krew install hns.

  • WILL NOT WORK UNTIL HNC v0.9.0 IS FULLY RELEASED

• Manually: Switch to any directory in your PATH (e.g. ~/bin) and run the following commands:

  HNC_VERSION=v0.9.0-rc1
  HNC_PLATFORM=linux_amd64 # also supported: darwin_amd64
  curl -L https://github.com/kubernetes-sigs/hierarchical-namespaces/releases/download/${HNC_VERSION}/kubectl-hns_${HNC_PLATFORM} -o ./kubectl-hns
  chmod +x ./kubectl-hns
  
  # Ensure the plugin is working
  kubectl hns
  # The help text should be displayed
