HNC v1.0.0 RC2
Pre-releaseHNC v1.0.0 RC2 is a candidate for our first production release. Based on the lack of stability issues reported against HNC v0.9, we believe that HNC is now suitable for use in production. It also introduces several new features including managed labels and annotations (beta) and HA support (experimental).
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=v1.0.0-rc2
# 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}/default.yaml
WARNING: if your cluster already has HNC installed, please ensure you are using HNC v0.9.0 or later before trying to upgrade to v1.0.0.
To install the kubectl plugin on your workstation, either use Krew or install manually:
-
