Add post-install script to setup init.d services and enable udev. Add lsblk and util-linux to dependancies. Add a patch to remove a debug line that appears on console during boot. Add README.Alpine to docs package. Prevent any pyc files from being packaged.
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.
