access service from host when ports and not linked

When I link the exposed ports within container to the host port, everything works as expected...

docker run -d -p 9200:9200 -p 9300:9300 elasticsearch

curl -XGET localhost:9200/_cat/indices

But when I do not use ports option with run command, I am not able to connect. 

# docker run -d elasticsearch

# docker inspect 87c6bcb3b67e | grep IPAddress
            "SecondaryIPAddresses": null,
            "IPAddress": "172.17.0.3",
                    "IPAddress": "172.17.0.3",

# curl -XGET 127.17.0.3:9200/_cat/indices
curl: (7) Failed to connect to 127.17.0.3 port 9200: Connection refused

I can log-in to container and access elasticsearch without any problem. like this...

# docker exec -it 2ec9026b755e bash

# curl -XGET localhost:9200/_cat/indices

Is there any way to access elasticsearch from host even if the ports are not linked?

Normally no: that is what container are for: providing isolation. That allows you to launch many containers, each one running on the same port.
