Node feature discovery for Kubernetes
f64c23968a
Update node status before node metadata. This fixes a problem where we lose track of NFD-managed extended resources in case patching node status fails. Previously we removed all labels and annotations (including the one listing our ERs) and only after that updated node status. If node status update failed we had lost the annotation but extended resources were still there, leaving them orphaned. |
