I use docker and Elasticsearch, i got confused, when i set the Elasticsearch url (when initialize it) in golang to "Elasticsearch:9200", the massages shows
> "health check timeout: no Elasticsearch node available"
but if i dont set anything the messages shows
: Head "http://127.0.0.1:9200": dial tcp 127.0.0.1:9200: connect: connection refused: no Elasticsearch node available
i dont know how to initialize data via .sh, json file, and connect it to golang for Elasticsearch. I have done some research for many dayt, but i still confused.
here is the yml file
version: '2.4'
services:
elasticsearch:
image: docker.elastic.co/elasticsearch/elasticsearch:7.17.0
healthcheck:
test: "curl http://elasticsearch:9200/_cluster/health"
environment:
- xpack.security.enabled=false
- discovery.type=single-node
- "ES_JAVA_OPTS=-Xms256m -Xmx256m"
ulimits:
memlock:
soft: -1
hard: -1
nofile:
soft: 65536
hard: 65536
ports:
- "9201:9200"
elasticsearch_seeder:
build:
context: ../../
dockerfile: ./build/package/seeder/Dockerfile
image: curlimages/curl:7.82.0
depends_on:
elasticsearch:
condition: service_healthy
command: sh -c "/elasticsearch_init.sh"
volumes:
- ./elasticsearch_init.sh:/elasticsearch_init.sh
- ./data.json:/data.json
and here is the .sh file
ES_HOST=elasticsearch:9200
curl -s -XPUT $ES_HOST/comics \
-H "Content-Type: application/json" \
-d '
{
"mappings": {
"dynamic": false,
"properties": {
"title": {
"type": "text"
},
"images":{
"type": "nested"
}
}
},
"settings": {
"analysis": {
"analyzer": {
"default": {
"type": "standard",
"stopwords": "_english_"
}
}
}
}
}
'
they are in a folder with data.json, which contain data for Elasticsearch.
this is how i initialize the Elasticsearch client in golang
config, err := elastic.NewClient(elastic.SetURL("elasticsearch:9200"))
im using "GitHub - olivere/elastic: Elasticsearch client for Go."
