Hi,  
When bringing up a docker container for ES, I am seeing this error:

```auto
ubuntu@ip-<>:~/ragflow/docker$ sudo docker inspect --format "{{json .State.Health }}" ragflow-es-01 | jq

```

Some System info:

I have already modified the security group settings to allow All TCP, SSH, HTTP, HTTPS (both inbound and outbound) [NOTE- ONLY TEMPORARILY FOR TRIAGE]. However the port 9200 isn't open.

```auto
ubuntu@ip-~/ragflow/docker$ nmap -p- localhost
Starting Nmap 7.94SVN ( https://nmap.org ) at 2024-06-22 07:12 UTC

```

These are the docker ps that are running:

```auto

```

docker compose logs just state this:

```auto
ragflow-es-01 | Created elasticsearch keystore in /usr/share/elasticsearch/config/elasticsearch.keystore
ragflow-es-01 | 
ragflow-es-01 | ERROR: Elasticsearch exited unexpectedly, with exit code 137

```

This is the elastisearch.yml from within the container

```auto
root@aefbd24acf01:/usr/share/elasticsearch/config# cat elasticsearch.yml 
cluster.name: "docker-cluster"
network.host: 0.0.0.0

```

And these are the logs from within the docker container itself:

Am I missing something blatantly obvious? I am new to dockers and EC2.

Would appreciate any help.  
Thank you
