docker error elastic search image not accessible with the parameters provided by the setup file

Question

I have a clustered Env with docker swarm. I upgraded elastic search image from 2.4 to 5.6 and now when I'm deploying my app, I get an error:

ERROR: Validation failed: Elastic search not accessible with the parameters provided by the setup file. Hosts: nga_es, Port: 9300, Cluster name: elasticsearch. Error: None of the configured nodes are available.

I get the error from the second container which trying to connect to elastic search.

This is the docker-compose.yml file (version 3) I wrote: (the relevant lines to elastic):

 nga_es:
networks:
  octanet:
    aliases:
    - nga_es
environment: 
  ES_JAVA_OPTS: '-Xms4G -Xmx4G'
tty: true
image: elasticsearch:5.6
ports:
- 9300
- 9200
stdin_open: true

Does someone has a clue why I'm getting this error? I'm out of ideas.

Answer 1

Did you read all the Docker Hub notes about that elasticsearch:5 image?

• It's being deprecated, best move to the official es image.

• Did you see the "cluster" notes about cluster setup and capabilities ES will need?
