Node feature discovery for Kubernetes
b6ff514853
Add support for detecting configuration file changes via file system notifications (fsnotify). Watches are added for the whole directory chain (up to root directory) so that all changes (even directory renames) affecting the given configuration file path are captured. Previously dynamic (re-)configuration of nfd-worker was implemented by (re-)reading the configuration file on every labeling pass. This was simple and effective, even if a bit wasteful. However, it didn't provide asynchronous configuration updates that will be required for e.g. controlling the "sleep-interval" parameter dynamically which will be implemented by later patches. |
