chrony is a daemon which implements the Network Time Protocol (NTP) is designed to synchronize system clocks across a variety of systems and use a source that is highly accurate. More information on chrony can be found at
https://chrony-project.org/.
Chrony can be configured to be a client and/or a server.
To enable Chronyd service, you can run:
# systemctl enable chronyd.service
This recommendation only applies if chrony is in use on the system.
If chrony is in use on the system proper configuration is vital to ensuring time synchronization is working properly.
The following script can be run on the host to remediate the issue.
#!/bin/bash
# Remediation is applicable only in certain platforms
if [ ! -f /.dockerenv ] && [ ! -f /run/.containerenv ] && { dpkg-query --show --showformat='${db:Status-Status}\n' 'chrony' 2>/dev/null | grep -q installed; }; then
SYSTEMCTL_EXEC='/usr/bin/systemctl'
"$SYSTEMCTL_EXEC" unmask 'chrony.service'
"$SYSTEMCTL_EXEC" start 'chrony.service'
"$SYSTEMCTL_EXEC" enable 'chrony.service'
else
>&2 echo 'Remediation is not applicable, nothing was done'
fi
The following playbook can be run with Ansible to remediate the issue.
