I am using official elastic search docker container image in docker compose in linux (ubunut 24.04 lts) . I am working with different project with having elastic search container image in each project so i can’t use the default host port. Like a default port binding host to container is 9200:9200 and I want to map this like 10200:9200. But this is not working.
I am try to connecting through js client of elastic search but it give
error called connection refused

How can i solve this ?

My docker-compose.yaml file is below

services:
    blog-elasticsearch:
        image: docker.elastic.co/elasticsearch/elasticsearch:8.15.0
        container_name: b-elasticsearch
        environment:
          - discovery.type=single-node
          - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
        ports:
          - "10200:9200"
          - "10300:9300" 
        volumes:
          - es_data:/usr/share/elasticsearch/data

Update i got the answer

So basically I got the answer . After go through lot of pain , i got the reason why i was getting error .

when I was building the elastic search container image through docker compose , after a very very short time i did the test to connect to the container . since it was not ready for getting the request from outside , the container was refusing to connect . So I got the error. But after a few second container was being connected from outside world.
