iBus Cannot Connect to Elasticsearch Node

[DawidLokiec]

Description:
I am trying to set up an InGrid node locally by manually installing the various components, dependencies, and modules for a minimal setup as descripted at https://www.ingrid-oss.eu/latest/system/installation.html:

• Elasticsearch
• iBus
• Portal
• iPlug IGE / InGrid Catalog
• Codelist Repository

1. I have installed the necessary dependency for Elasticsearch using the Docker container provided at https://docker-registry.wemove.com/ingrid-elasticsearch-with-decompound:6.4.2.
2. For the Elasticsearch cluster configuration, I have set up the following docker-compose.yml file:

version: '3'
services:
  elastic:
    image: docker-registry.wemove.com/ingrid-elasticsearch-with-decompound:6.4.2
    restart: unless-stopped
    ports:
      - "9200:9200"
      - "9300:9300"
    environment:
      - TZ=Europe/Berlin
      - cluster.name=ingrid
      - http.host=0.0.0.0
      - transport.host=0.0.0.0
      - http.cors.enabled=true
      - http.cors.allow-origin=*
      - "ES_JAVA_OPTS=-Xms1G -Xmx1G"
      - xpack.security.enabled=false
      - xpack.monitoring.enabled=false
      - xpack.ml.enabled=false
    ulimits:
      nofile:
        soft: 65536
        hard: 65536
    deploy:
      resources:
        limits:
          memory: 1024M

These settings were taken 1:1 from https://github.com/informationgrid/ingrid-docker/blob/main/docker-compose.yml and I added the following port mapping for safety:

    ports:
      - "9200:9200"
      - "9300:9300"

3. I have confirmed that the Elasticsearch cluster is up and running. It is accessible at http://localhost:9200/ and shows the following information:

{
  "name" : "tth8Nt0",
  "cluster_name" : "ingrid",
  "cluster_uuid" : "85PCb6KXT9-RZCyrU8rl9Q",
  "version" : {
    "number" : "6.4.2",
    "build_flavor" : "default",
    "build_type" : "tar",
    "build_hash" : "04711c2",
    "build_date" : "2018-09-26T13:34:09.098244Z",
    "build_snapshot" : false,
    "lucene_version" : "7.4.0",
    "minimum_wire_compatibility_version" : "5.6.0",
    "minimum_index_compatibility_version" : "5.0.0"
  },
  "tagline" : "You Know, for Search"
}

4. The cluster is in a green state (http://localhost:9200/_cluster/health):

{
  "cluster_name": "ingrid",
  "status": "green",
  "timed_out": false,
  "number_of_nodes": 1,
  "number_of_data_nodes": 1,
  "active_primary_shards": 0,
  "active_shards": 0,
  "relocating_shards": 0,
  "initializing_shards": 0,
  "unassigned_shards": 0,
  "delayed_unassigned_shards": 0,
  "number_of_pending_tasks": 0,
  "number_of_in_flight_fetch": 0,
  "task_max_waiting_in_queue_millis": 0,
  "active_shards_percent_as_number": 100
}

5. I have successfully installed the iBus component on Windows (not within a Docker container) and it is accessible at http://localhost:9901.

Problem:
When navigating to http://localhost:9901/#/indices, I receive the following error:

In the iBus log file (log.log), I see the following errors:

INFO [2024-06-10 08:39:06] (ConfigurationService.java:77) - Elasticsearch not connected ... Reconnecting

org.elasticsearch.client.transport.NoNodeAvailableException: None of the configured nodes are available: [{#transport#-1}{0ExqjCmhQjqwQTJNLKChKA}{localhost}{127.0.0.1:9300}]

Additional Information:

• I installed iBus manually on Windows because the Docker images did not work for me.
• I did not change the default settings of iBus.
• I installed ingrid-ibus-7.1.0-installer.jar.
• I have attached the log.log file for more details.

Question:
What am I doing wrong? How can I ensure that iBus communicates correctly with the Elasticsearch node?

Attachments:

• log.log
• application-default.properties

I encounter the same problem setting up InGrid with the docker setup (https://github.com/informationgrid/ingrid-docker) on Ubuntu Desktop 24.04. Same exceptions in the iBus logs.
