Elasticsearch can't find hunspell - docker

Question

I'm running elasticsearch from a docker-compose.yml file:
version: '3'
services:
mongo:
image: mongo
container_name: mongo-cust-mycom
ports:
- 27017:27017
volumes:
- cust-mycom-mongo:/data/db
networks:
- cust-mycom
elasticsearch:
image: docker.elastic.co/elasticsearch/elasticsearch:6.5.4
container_name: elasticsearch-cust-mycom
ports:
- 9200:9200
- 9300:9300
volumes:
- cust-mycom-elastic:/usr/share/elasticsearch/data
- ./cust/config/elasticsearch/config/hunspell:/usr/share/elasticsearch/config/hunspell
networks:
- cust-mycom
environment:
- cluster.name=i3-elasticsearch
- xpack.security.enabled=false
- xpack.monitoring.enabled=false
- xpack.ml.enabled=false
- xpack.graph.enabled=false
- xpack.watcher.enabled=false
restart: unless-stopped
kibana:
image: docker.elastic.co/kibana/kibana:6.5.4
container_name: kibana-cust-mycom
ports:

depends_on:
- elasticsearch
restart: unless-stopped
networks:
cust-mycom:
driver: bridge
volumes:
cust-mycom-mongo:
cust-mycom-elastic:
using docker-compose up -d.
When I try to create my desired index, using the following json:
{
"settings": {
"number_of_shards": 3,
"number_of_replicas": 2,
"analysis": {
"filter": {
"swedish_stemmer": {
"type": "hunspell",
"language": "sv_SE"
},
"ins_pattern": {

"patterns": [
"([a-zåäö]*)(prod)"
]
},
"cust_stopwords": {
"type": "stop",
"stopwords": [ "en", "ett", "det", "den" ]
}
},
"analyzer": {
"swedish_index": {
"tokenizer": "standard",
"filter": [

"ins_pattern",
"swedish_stemmer"
]
},
"swedish_query": {

]
}
}
}
},
"mappings": {

},

},
"validUntil": {
"type": "date",

},
"informationType": {
"type": "text",
"store": true,
"norms": false,
"analyzer": "swedish_index",
"search_analyzer": "swedish_query"
},
"mainContentOfPage": {
"type": "text",
"store": true,
"norms": false,
"analyzer": "swedish_index",
"search_analyzer": "swedish_query",
"term_vector": "with_positions_offsets"
},
"thumbnailUrl": {

"type": "text",
"store": true,
"norms": false,
"analyzer": "swedish_index",
"search_analyzer": "swedish_query"
}
}
}
}
}
and the following script:
#!/bin/bash
curl -XDELETE http://localhost:9200/main
curl -XPUT -H "Content-type: application/json" -d #json/custse.index.json http://localhost:9200/main
curl -XPUT http://localhost:9200/main/_settings -H "Content-Type: application/json" -d "{
\"index\" : {
\"number_of_replicas\" : 0
}
}"
I get the following error message:
{"error":{"root_cause":[{"type":"illegal_state_exception","reason":"failed to load hunspell dictionary for locale: sv_SE"}]
I've tried putting my hunspell dictionaries in /usr/share/elasticsearch/config/hunspell/, /usr/share/elasticsearch/hunspell, /etc/elasticsearch/hunspell and /etc/elasticsearch/config/hunspell. It can't find any of them.
Here are the contents of the hunspell file:
/etc/elasticsearch$ ls hunspell
sv_SE
/etc/elasticsearch$ ls hunspell/sv_SE/
cust.dic README_sv_SE.txt sv_SE.aff sv_SE.dic
How can I make elasticsearch find the hunspell dictionaries?

- "127.0.0.1:9200:9200"
environment:
- "ES_JAVA_OPTS=-Xms256m -Xmx256m"
restart: always
volumes:
- "es_data:/usr/share/elasticsearch/data"
- ./elasticsearch/hunspell:/usr/share/elasticsearch/config/hunspell
