supported using Nix 1.11 by setting <literal>nix.package =

The ELK stack: <varname>elasticsearch</varname>, <varname>logstash</varname> and <varname>kibana</varname>
|
|
has been upgraded from 2.* to 6.3.*.
|
|
The 2.* versions have been <link xlink:href="https://www.elastic.co/support/eol">unsupported since last year</link>
|
|
so they have been removed. You can still use the 5.* versions under the names
|
|

<varname>kibana5</varname>.

<varname>filebeat</varname>, <varname>heartbeat</varname>,

<varname>metricbeat</varname> and <varname>packetbeat</varname>
|
|
have had the same treatment: they now target 6.3.* as well.

The 5.* versions are available under the names:

<varname>filebeat5</varname>, <varname>heartbeat5</varname>,

<varname>metricbeat5</varname> and <varname>packetbeat5</varname>

The ELK-6.3 stack now comes with

<link xlink:href="https://www.elastic.co/products/x-pack/open">X-Pack by default</link>.

Since X-Pack is licensed under the
|
|
<link xlink:href="https://github.com/elastic/elasticsearch/blob/master/licenses/ELASTIC-LICENSE.txt">Elastic License</link>
|
|
the ELK packages now have an unfree license. To use them you need to specify
|
|
<literal>allowUnfree = true;</literal> in your nixpkgs configuration.

</para>
|
|
<para>
|

Fortunately there is also a free variant of the ELK stack without X-Pack.

The packages are available under the names:

The <literal>pkgs</literal> argument to NixOS modules can now be set directly using <literal>nixpkgs.pkgs</literal>. Previously, only the <literal>system</literal>, <literal>config</literal> and <literal>overlays</literal> arguments could be used to influence <literal>pkgs</literal>.

A NixOS system can now be constructed more easily based on a preexisting invocation of Nixpkgs. For example:
|
|
<programlisting>
|
|
inherit (pkgs.nixos {
|
|
boot.loader.grub.enable = false;
|
|
fileSystems."/".device = "/dev/xvda1";
|
|
}) toplevel kernel initialRamdisk manual;
|
|
</programlisting>
|
|
|
|
This benefits evaluation performance, lets you write Nixpkgs packages that depend on NixOS images and is consistent with a deployment architecture that would be centered around Nixpkgs overlays.

If dashboard cluster-admin rights are desired,
