HNC v1.1.0 Latest
Latest

HNC v1.1.0 introduces beta support for Hierarchical Resource Quotas (HRQ), opt-in propagation, and better support for K8s-based platforms such as Rancher.

New: please sign up for low-volume announcements of new versions, proposed changes, and critical issues at kubernetes-hnc-announce.

Installing

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

# Select the latest version of HNC
HNC_VERSION=v1.1.0

# Select the variant of HNC you like. Other than 'default', options include:
# 'hrq': Like default, but with hierarchical quotas.
# 'ha': Like default, but with two deployments: one single-pod for the controller, and one three-pod for the webhooks
# 'default-cm': Like default, but without the built-in cert rotator, and with support for cert-manager
HNC_VARIANT=default

# 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_VARIANT}.yaml

WARNING: if your cluster already has HNC installed, please ensure you are using HNC v1.0.0 or later before trying to upgrade to v1.1.0.

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 update && kubectl krew install hns.

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

    # Ensure HNC_VERSION is set as above
HNC_PLATFORM=linux_amd64 # also supported: linux_arm64, darwin_amd64, darwin_arm64, windows_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

For more instructions, see the user guide.

What's changed since HNC v1.0

  • Beta - Hierarchical Resource Quotas (HRQ): Drop-in replacement for many regular ResourceQuota use-cases, but across related namespaces.
  • Beta - Opt-in propagation: Allow propagation for a certain type, but disable it by default. Objects are propagated case-by-case based on annotations.
  • Move built-in propagation exceptions to the command line: the new --nopropagation-label command-line flag gives admins more flexible option to control propagation on objects you don't create.

HNC v0.9.0

HNC v0.9.0 is our first release from our new repo, and includes many feature and usability improvements to object propagation and cluster control.

Installing

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

# 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

WARNING: if your cluster already has HNC installed, please ensure you are using HNC v0.8.0 or later before trying to upgrade to v0.9.0.

If you previously annotated your system namespaces with hnc.x-k8s.io/excluded-namespace (as described here), you may remove these annotations after HNC v0.9 is installed. This annotation is no longer necessary and is ignored.

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.

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

chmod +x ./kubectl-hns

# Ensure the plugin is working
kubectl hns
# The help text should be displayed

For more instructions, see the user guide.

Known issues

  • Tree labels can be briefly modified before HNC resets them (#12)
  • Annotations can be added to propagated objects (#10)

What's Changed since HNC v0.8.0

  • Simplify administration of managed namespaces by adding --included-namespace-regex (#89) and simplifying labels for webhooks (#36, #39)
  • Unbreak HNC on K8s 1.22 (#86)
  • Allow HNC to propagate changes to CRDs (#59)
  • Disable kube-rbac-proxy by default (#50)
  • Don't panic on cluster-scoped resources (#72)
  • Disable stackdriver by default (#77)
  • Include Windows CLI to releases (#78)

HNC v0.9.0 RC1 Pre-release
Pre-release

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

For more instructions, see the user guide.
