A major refactoring of the Kubernetes module has been completed.
|
|
Refactorings primarily focus on decoupling components and enhancing
|
|
security. Two-way TLS and RBAC has been enabled by default for all
|
|
components, which slightly changes the way the module is configured.

The <literal>nscd</literal> service now disables all caching of
|
|
<literal>passwd</literal> and <literal>group</literal> databases by
|
|
default. This was interferring with the correct functioning of the
|
|
<literal>libnss_systemd.so</literal> module which is used by
|
|
<literal>systemd</literal> to manage uids and usernames in the presence of
|
|
<literal>DynamicUser=</literal> in systemd services. This was already the
|
|
default behaviour in presence of <literal>services.sssd.enable =
|
|
true</literal> because nscd caching would interfere with
|
|
<literal>sssd</literal> in unpredictable ways as well. Because we're
|
|
using nscd not for caching, but for convincing glibc to find NSS modules
|
|
in the nix store instead of an absolute path, we have decided to disable
|
|
caching globally now, as it's usually not the behaviour the user wants and
|
|
can lead to surprising behaviour. Furthermore, negative caching of host
|
|
lookups is also disabled now by default. This should fix the issue of dns
|
|
lookups failing in the presence of an unreliable network.

If the old behaviour is desired, this can be restored by setting

GitLab Shell previously used the nix store paths for the

not necessary anymore, but there might be leftover lines with a nix store

path. Regenerate the <literal>authorized_keys</literal> file via

<literal>mailutils</literal> now works by default when

<literal>sendmail</literal> is not in a setuid wrapper. As a consequence,

the <literal>sendmailPath</literal> argument, having lost its main use, has
|
|
been removed.

The <option>services.matomo</option> module gained the option

<option>services.matomo.package</option> which determines the used

Matomo version.

The Matomo module now also comes with the systemd service <literal>matomo-archive-processing.service</literal>

and a timer that automatically triggers archive processing every hour.
|

This means that you can safely

|

but make sure that you run <literal>systemctl start matomo-archive-processing.service</literal>
|
|
at least once without errors if you have already collected data before,
|
|
so that the reports get archived before the source data gets deleted.

The deprecated <literal>truecrypt</literal> package has been removed

and <literal>truecrypt</literal> attribute is now an alias for

<literal>veracrypt</literal>. VeraCrypt is backward-compatible with

TrueCrypt volumes. Note that <literal>cryptsetup</literal> also
|

supports loading TrueCrypt volumes.

The Kubernetes DNS addons, kube-dns, has been replaced with CoreDNS.
|
|
This change is made in accordance with Kubernetes making CoreDNS the official default
|
|
starting from
|
|
<link xlink:href="https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG-1.11.md#sig-cluster-lifecycle">Kubernetes v1.11</link>.
|
|
Please beware that upgrading DNS-addon on existing clusters might induce
|
|
minor downtime while the DNS-addon terminates and re-initializes.
|
|
Also note that the DNS-service now runs with 2 pod replicas by default.
|
|
The desired number of replicas can be configured using:
|
|
<option>services.kubernetes.addons.dns.replicas</option>.

It is possible now to uze ZRAM devices as general purpose ephemeral block devices,
|
|
not only as swap. Using more than 1 device as ZRAM swap is no longer recommended,
|
|
but is still possible by setting <literal>zramSwap.swapDevices</literal> explicitly.

Default algorithm for ZRAM swap was changed to <literal>zstd</literal>.

Changes to ZRAM algorithm are applied during <literal>nixos-rebuild switch</literal>,

use <literal>nixos-rebuild boot; reboot</literal>.

Symlinks in <filename>/etc</filename> (except <filename>/etc/static</filename>)

are now relative instead of absolute. This makes possible to examine

NixOS container's <filename>/etc</filename> directory from host system

|
|
and to container <filename>/etc</filename> when viewed from container chroot).

Flat volumes are now disabled by default in <literal>hardware.pulseaudio</literal>.
|
|
This has been done to prevent applications, which are unaware of this feature, setting
|
|
their volumes to 100% on startup causing harm to your audio hardware and potentially your ears.

<note>

<para>
|
|
With this change application specific volumes are relative to the master volume which can be
|
|
adjusted independently, whereas before they were absolute; meaning that in effect, it scaled the
|
|
device-volume with the volume of the loudest application.

The use of insecure ports on kubernetes has been deprecated.
|

Thus options:
|
|
<varname>services.kubernetes.apiserver.port</varname> and
|
|
<varname>services.kubernetes.controllerManager.port</varname>
|
|
has been renamed to <varname>.insecurePort</varname>,
|

and default of both options has changed to 0 (disabled).

Note that the default value of

|

has changed from 127.0.0.1 to 0.0.0.0, allowing the apiserver to be
|
|
accessible from outside the master node itself.
|
|
If the apiserver insecurePort is enabled,
|
|
it is strongly recommended to only bind on the loopback interface. See:

<varname>services.kubernetes.apiserver.insecurebindAddress</varname>.

The <literal>intel</literal> driver has been removed from the default list of
|
|
<link linkend="opt-services.xserver.videoDrivers">X.org video drivers</link>.
|
|
The <literal>modesetting</literal> driver should take over automatically,
|
|
it is better maintained upstream and has less problems with advanced X11 features.
|
|
This can lead to a change in the output names used by <literal>xrandr</literal>.
|
|
Some performance regressions on some GPU models might happen.
|
|
Some OpenCL and VA-API applications might also break
|
|
(Beignet seems to provide OpenCL support with
|
|
<literal>modesetting</literal> driver, too).
|
|
Users who need this functionality more than multi-output XRandR are advised
|
|
to add `intel` to `videoDrivers` and report an issue (or provide additional
|
|
details in an existing one)

Openmpi has been updated to version 4.0.0, which removes some deprecated MPI-1 symbols.
|
|
This may break some older applications that still rely on those symbols.
