The Alpine /etc/hosts template results in a file where the long form of
names (including localhost) come before the short form. This means that
when running tools like 'netstat' and 'ss' which convert IP address to
names that their output will show 'localhost.localdomain' rather than
'localhost.' This patch swaps the order of the short and long form names
so such utils will show the short form name.
It also removes several unnecessary IPv6-specific entries.

Add IPv6 localhost (::1) entry. See:
https://salsa.debian.org/installer-team/netcfg/-/blob/1767c9264e04652b9150ffc7b25568e4ea6b2bdd/netcfg.h#L42
https://salsa.debian.org/md/netbase/-/blob/9de8afcad482418cc4956dc09bbf6a2e8624d574/debian/netbase.postinst#L8
Also remove ip6-localnet, ip6-mcastprefix, and ip6-allhosts. See:

Also added a new (currently experimental) systemd-networkd renderer,
and includes a small refactor to cc_resolv_conf.py to support the
resolved.conf used by systemd-resolved.
|
|
Move chef_license from TPL_PATH_KEYS to TPL_KEYS as the chef license
setting is not a path but must be added to the client config template.
Fixes file or folder not found exception raised from ensure_dirs.

Add new module cc_apk_configure for creating Alpine /etc/apk/repositories file.
Modify cc_ca_certs, cc_ntp, cc_power_state_change, and cc_resolv_conf for Alpine.
Add Alpine template files for Chrony and Busybox NTP support.
Add Alpine template file for /etc/hosts.

Move from 127.0.0.1 to 127.0.1.1 for localhost IP addr for opensuse and sles

(#251)
This is a follow-up to #144 which fixed the rendering behaviour.
While writing the tests, CI failed due to dict iteration differences across Python versions, so this also sorts output so that we will produce the same output across Python versions.

The debian ntp.conf template did not contain a newline for the
comment used to mark the rendered ntp pools configured. This
resulted in an invalid line:
'# poolspool 0.int.pool.ntp.org iburst'
rather than:
'# pools
pool 0.int.pool.ntp.org iburst'
This patch fixes the template and updates the unittest to
verify that the rendered templates puts servers and pools
at the beginning of a line.

Encrypted data bags require a secrets file to be present to
decrypt, and the location of the file must be configured the
Chef client configuration file, client.rb.
This update enables cloud-init's chef module to update that
setting in client.rb.
LP: #1817082

Other installation modes began to comment out the deb-src lines in
/etc/apt/sources.list sometime in 16.04 time frame.
This makes the cloud-init rendered sources.list the same as that
currently present in the lxd images.
The changes here are:
a.) comment out all 'deb-src' lines.
b.) move security to the bottom of the file.
c.) trim trailing white space from 3 comment lines.

If a file passed to render_from_file had non-ascii text then
jinja in python2 would decode as ascii, which would cause
UnicodeDecodeError. This issue can be re-created in python2
with just:
'can\xe2\x80\x99t'.decode()
The solution here is to explicitly pass in unicode supporting
type (py3 str, py2 unicode). Those are six.text_type.
Then jinja does not try to decode.
The reason we hit this is that load_file calls decode_binary.
decode_binary believes it has no work to do if it got a six.string_types.
isinstance('can\xe2\x80\x99t', six.string_types) == True
So it returns the original string which will blow up for jinja.
Our fix here then is to load the file in binary mode and explicitly
decode it to utf-8. Then in python2 we'll have a unicode type
and in python3 we'll have a string type.

Add a base NTP client configuration dictionary and allow Distro
specific changes to be merged. Add a select client function which
implements logic to preferr installed clients over clients which
need to be installed. Also allow distributions to override the
cloud-init defaults.
LP: #1749722

Add opensuse distro support to cc_ntp module.
LP: #1726572
|
|
The etc/hosts file is was not properly setup for openSUSE or SLES
when manage_etc_hosts is set in the config file.
Improve the doc to address the fact that the 'localhost' ip is
distribution dependent (not always 127.0.0.1).
LP: #1731022
|
|
This gets initial opensuse and SLES support back to a working state.
Still missing is more complete network file writing and unit tests.
|
|
The Debian GNU/Linux distribution doesn't come offically with the
non-free repositories enabled. Therefore, we want to disable those in
the cloud-init template.

Some systems like Ubuntu-Core do not provide an ntp package for
installation but do include systemd-timesyncd (an ntp client).
On such systems cloud-init will generate a timesyncd configuration
using the 'servers' and 'pools' values as ntp hosts for timesyncd to use.

The comments in the debian template file of /etc/hosts still pointed
to a general template file instead of the debian one.
LP: #1606406
|

This just adds an entry for hostname and fqdn to 127.0.0.1 in
templates/hosts.suse.tmpl.
|

Debian backports are contains in the main repo and not somewhere
seperate. Thanks to Charles Plessy.
LP: #1627293

Add support for installing and configuring ntp service, exposing the
minimum config of servers or pools to be added. If none are defined
then fallback on generating a list of pools by distro hosted at
pool.ntp.org (which matches what's found in the default ntp.conf
shipped in the respective distro).
|
|
templates/sources.list.ubuntu.tmpl was inadvertantely
changed in a previous commit. Simply revert to older version.
|
|
Things here:
- restart rather than 'start' the service, to pick up a config change
that we would have written.
- update the config and write cert files whether or not the file
existed on the system. Previously it would only write the cert
files if /etc/mcollective/server.cfg already existed.
- improve test coverage
|
|
Now, validation_key is always a path to a file, as it is in
chef's client.rb syntax.
validation_cert is always the *content* of that file that should
be written. However, if validation_cert is the string "system",
then we do not write that value, but rather assume the file exists.

Previous commit intended to enable backports, but failed to do so.
|
|
This modifies a designed decision to have trimmer sources.list than
one would find on a server iso install. Specifically, here we now
enable: restricted and multiverse and backports.

- Use the generated_by() utility function to
give the ruby template a better header comment
- Set special parameters after selecting the basic
chef parameters.
|
|
Add the following adjustments to the chef template and module
- Make it so that the chef directories can be provided (defaults
to the existing directories)
- Make the params much more configurable, and if a parameter is
provided in the chef configuration it will override existing template
parameters.
- Make the template skip lines if the values are None in the configuration
so that template lines can be removed if/when this is desirable.
- Allow the firstboot json path to be configurable (defaults to the
existing location).
- Adds a basic set of tests to ensure that good things are happening.

this makes some changes to the cc_resolv_conf to make its
generate_resolv_conf method more easily callable (for future test).
Also sets it up so that 'options' is always defined when the template
is rendered.

Right now, all distros but ubuntu will fail to manage /etc/hosts.
This is due to the fact that the templates are named:
- hosts.ubuntu.tmpl
- hosts.redhat.tmpl
The config handler is specifically looking for a template with the
given distro name.
This change addresses this issue.

Managing resolv.conf can be quite handy when running in an environment
where you would like to control DNS resolution, despite being provided
DNS server information by DHCP. This module will allow one to define the
structure of their resolv.conf and write it PER_ONCE.
Right now this makes the most sense on RedHat, and therefore, has defined
'distros' as such.

There are several changes here.
* Datasource now has a 'availability_zone' getter.
* get_package_mirror_info
* Datasource convenience 'get_package_mirror_info' that calls
the configured distro, and passes it the availability-zone
* distro has a get_package_mirror_info method
* get_package_mirror_info returns a dict that of name:mirror
this is to facilitate use of 'security' and 'primary' archive.
* this supports searching based on templates. Any template
that references undefined values is skipped. These templates
can contain 'availability_zone' (LP: #1037727)
* distro's mirrors can be arch specific (LP: #1028501)
* rename_apt_lists supports the "mirror_info" rather than single mirror
* generate_sources_list supports mirror_info, and as a result, the
ubuntu mirrors reference '$security' rather than security (LP: #1006963)
* remove the DataSourceEc2 specific mirror selection, but instead
rely on the above filtering, and the fact that 'ec2_region' is only
defined if the availability_zone looks like a ec2 az.

At this point there is a mixture of "double hash" cheetah comments and '#*'
cheetah comments.
|
|
now will be done by the distro classes (since its not the same for rhel and ubuntu).
Remove the template also since it will just be created by the ubuntu distro class (its just one line).
|
|
|
|
Also converted all the other templates to tempita format instead of the more complicated (and more dependent on other packages) cheetah format.
