emilyls/chrony repository overview
Chrony
A container and helm chart for chrony, a versatile implementation of the Network Time Protocol (NTP).
The Helm Chart sets up a Kubernetes DaemonSet that ensures chrony runs on every node in your cluster, synchronising the system time with NTP servers, other peers, or reference clocks.
Optionally, it can also be configured to act as an NTPv4 (RFC 5905) server.
Usage
helm install chrony chart --values values.yaml
Add Servers
# values.yaml
config:
pools:
- "pool.example.net"
servers:
- "server.example.com"
