elastic exporter - connection refused - elasticsearch

Question

trying to set up elastic exporter for a local stack :
https://github.com/prometheus-community/elasticsearch_exporter
I get a connection refused when running with a docker even when xpack security is disabled.
xpack.license.self_generated.type: basic
xpack.security.enabled: false
xpack.monitoring.collection.enabled: true
xpack.monitoring.exporters.my_local_exporter:
type: local
bootstrap.memory_lock: true
search.allow_expensive_queries: true
indices.memory.index_buffer_size: 30%
I use elastic 8.1.2 :
{
"name" : "0a166124ca20",
"cluster_name" : "docker-cluster",
"cluster_uuid" : "xxxxxxxxxxxxxxx",
"version" : {
"number" : "8.1.2",
"build_flavor" : "default",
"build_type" : "docker",
"build_hash" : "xxxxxxxxxxxxxxx",
"build_date" : "2022-03-29T21:18:59.991429448Z",
"build_snapshot" : false,
"lucene_version" : "9.0.0",
"minimum_wire_compatibility_version" : "7.17.0",
"minimum_index_compatibility_version" : "7.0.0"
},
"tagline" : "You Know, for Search"
}
I get limited amount of metrics but missing the majoriy
for example --> elasticsearch_node_stats_up 0
here is my docker-compose:
elasticsearch_exporter:
image: quay.io/prometheuscommunity/elasticsearch-exporter:latest
command:
- '--es.uri=http://localhost:9200'
- '--es.ssl-skip-verify'
- '--es.all'
restart: always
environment:
- 'ES_API_KEY=Apikey xxxxxxxxxx'
ports:
- "9114:9114"
