When the cloud-init package is installed it will enable its init.d services
|
|
so that they are run upon future boots/reboots. It also enables eudev's
|
|
init.d services as udev is used by cloud-init for both disk configuration and
|
|
network card persistent naming.

NTP
|
|
---
|
|
|
|
It is recommended that you enable a NTP client on the machine. Cloud-init
|
|
supports both Chrony (fully featured) and Busybox's NTP client (a minimal
|
|
implementation).
|
|
|
|
Chrony is the default NTP client in cloud-init for Alpine Linux.
|
|
|
|
|
|
To use Chrony as the NTP client:
|
|
|
|
Install the chrony package and enable the chrony init.d service
|
|
|
|
# apk add chrony
|
|
# rc-update add chronyd default
|
|
|
|
Specify a ntp section in your cloud-init User Data like so:
|
|
|
|
ntp:
|
|
pool:
|
|
- 0.uk.pool.ntp.org
|
|
- 1.uk.pool.ntp.org
|
|
|
|
If you do not specify any pool or servers then 0.pool.ntp.org ->
|
|
3.pool.ntp.org will be used.
|
|
|
|
The file /etc/cloud/templates/chrony.conf.alpine.tmpl is used by cloud-init
|
|
as a template to create the configuration file /etc/chrony/chrony.conf.
|
|
|
|
|
|
To use Busybox as the NTP client:
|
|
|
|
|
|
Edit the /etc/conf.d/ntpd file and change the line:
|
|
|
|
NTPD_OPTS="-N -p pool.ntp.org"
|
|
|
|
so that it is instead:
|
|
|
|
NTPD_OPTS="-N"
|
|
|
|
This changes the NTP client from using the hardcoded NTP server
|
|
"pool.ntp.org" to instead use the /etc/ntp.conf file which will be
|
|
generated by cloud-init upon first boot.
|
|
|
|
Enable the ntp init.d service:
|
|
|
|
# rc-update add ntpd default
|
|
|
|
Specify a ntp section in your cloud-init User Data like so:
|
|
|
|
ntp:
|
|
ntp_client: ntp
|
|
servers:
|
|
- 192.168.0.1
|
|
- 192.168.0.2
|
|
|
|
If you do not specify any servers then 0.pool.ntp.org -> 3.pool.ntp.org
|
|
will be used.
|
|
|
|
The file /etc/cloud/templates/ntp.conf.alpine.tmpl is used by cloud-init
|
|
as a template to create the configuration file /etc/ntp.conf.

Known Issues
|
|
============
|
|
|
|
|
|
cc_ca_certs module
|
|
------------------
|
|
|
|
The remove-defaults option of the cloud-init cc_ca_certs module does not
|
|
currently work correctly. This option will delete certificates installed by
|
|
the Alpine ca-certificates package as expected. However the certificates
|
|
provided by the ca-certificates-bundle package, which is always automatically
|
|
installed in an Alpine system due to it being a dependancy of a base package,
|
|
are not deleted.
