3a1e1f0624 adds a poststart script that
checks if ES successfully started by curling the HTTP endpoint. On nodes with a lot of data or slower disks,
this might take longer than the default systemd startup timeout of 90 seconds.
Before this fix, if the listenAddress is set to something else than 127.0.0.1,
the service fails to detect that Elasticsearch has properly started and stop.
Other services that depend on elasticsearch should be started after
it, but since the versions we're packaging have to run as
"Type=simple", they're started as soon as the elasticsearch binary has
been executed, likely winning the race against it.
This makes sure elasticsearch is up and running, responding to a
simple query, before dependents are started.
This adds the following new packages:
+ elasticsearch7
+ elasticsearch7-oss
+ logstash7
+ logstash7-oss
+ kibana7
+ kibana7-oss
+ filebeat7
+ heartbeat7
+ metricbeat7
+ packetbeat7
+ journalbeat7
The default major version of the ELK stack stays at 6. We should
probably set it to 7 in a next commit.
* The ELK stack is upgraded to 6.3.2.
* `elasticsearch6`, `logstash6` and `kibana6` now come with X-Pack which is
a suite of additional features. These are however licensed under the unfree
"Elastic License".
* Fortunately they also provide OSS versions which are now packaged
under: `elasticsearch6-oss`, `logstash6-oss` and `kibana6-oss`.
Note that the naming of the attributes is consistent with upstream.
* The test `nix-build nixos/tests/elk.nix -A ELK-6` will test the OSS
version by default. You can also run the test on the unfree ELK using:
`NIXPKGS_ALLOW_UNFREE=1 nix-build nixos/tests/elk.nix -A ELK-6 --arg enableUnfree true`
I don't know where this comes from (I accidentally did that as well
once), but some derivations seem to use `buildPhases` rather than
`phases` in their derivations.
This kills all improper usages as the lack of a `phases` argument
didn't break the build, so this can be safely removed.
* Add kibana5 and logstash5
* Upgrade the elastic beats to 5.4
* Make sure all elastic products use the same version
(see elk5Version)
* Add a test for the ELK stack
