systemd is starting pulseaudio for user (jenkins) without login which causes problems running jackd

By -

psaux shows that 2 instances of pulseaudio are being started on boot: one for the only active user on the system, and one for a limited-use non-login user that provides a CI service and does not have access to the audio group. When running jackd, pulseaudio is killed and the re-run using "pactl set-default-sink jack_out" in the "Execute script after startup" options. If both instances of pulseaudio are killed, this works, but it would make more sense not to run pulseaudio for jenkins in the first place.

jenkins     1718  0.0  0.0 290224 14056 ?        Ssl  05:48   0:00 /usr/bin/pulseaudio --daemonize=no --log-target=journal
mark        1970  0.2  0.1 1302508 19416 ?       S<sl 05:53   0:08 /usr/bin/pulseaudio --daemonize=no --log-target=journal

Reading on how to disable pulse for specific users suggests a couple of approaches, but both fail:

$ sudo -i
$ su jenkins
$ pstree -sp 1718
systemd(1)───systemd(1706)───pulseaudio(1718)─┬─{pulseaudio}(1749)
                                          └─{pulseaudio}(1750)

$ systemctl --user disable pulseaudio.service pulseaudio.socket
Failed to connect to bus: No such file or directory

$ systemctl --user mask pulseaudio.socket
Failed to connect to bus: No such file or directory

So either the correct env is not being picked up when doing the sudo -i/su thing, or this is not the right approach.

Any ideas how to disable whatever systemd is doing to cause pulseaudio to be started for the jenkins user?

Thanks

Spring Elasticsearch Operations

By -
Elasticsearch Operations Spring Data Elasticsearch uses two interfaces to define the operations that can be called against an Elasticsearch index. These are ElasticsearchOperations and ReactiveElasticsearchOperations. Whereas the first is used with the classic synchronous implementations, the second one uses reactive infrastructure. The default implementations of the interfaces offer: Read/Write mapping support for domain types. A rich query and criteria api. Resource management and Exception translation. ElasticsearchTemplate The ElasticsearchTemplate is an implementation of the ElasticsearchOperations interface using the Transport Client. @Configuration public class TransportClientConfig extends ElasticsearchConfigurationSupport {   @Bean   public Client elasticsearchClient() throws UnknownHostException {                      Settings settings = Settings.builder().put("cluster.name", "elasticsearch")....

Hibernate Search - Elasticsearch with JSON manipulation

By -
Elasticsearch with JSON manipulation Elasticsearch ships with many features. It is possible that at some point, one feature you need will not be exposed by the Search DSL. To work around such limitations, Hibernate Search provides ways to: Transform the HTTP request sent to Elasticsearch for search queries. Read the raw JSON of the HTTP response received from Elasticsearch for search queries. Direct changes to the HTTP request may conflict with Hibernate Search features and be supported differently by different versions of Elasticsearch. Similarly, the content of the HTTP response may change depending on the version of Elasticsearch, depending on which Hibernate Search features are used, and even depending on how Hibernate Search features are implemented. Thus, features relying on direct access to HTTP requests or responses cannot be guaranteed to continue to work when upgrading Hibernate Search, even for micro upgrades (x.y.z to x.y.(z+1)). Use this at your own risk....
