Error: Enter Elasticsearch host

[sevenval-admins]

Hallo to everyone, I have seen that there are already some discussion about this argument but it seem that anyone was solved:
If I run
docker run -d -v /tmp/elastalert.yaml:/opt/elastalert/config.yaml jertel/elastalert2
then I get the error:

Traceback (most recent call last):
  File "/usr/local/bin/elastalert-create-index", line 8, in <module>
    sys.exit(main())
  File "/usr/local/lib/python3.10/site-packages/elastalert/create_index.py", line 219, in main
    host = args.host if args.host else input('Enter Elasticsearch host: ')
EOFError: EOF when reading a line

When I run it as k8s deployment, I get the same error:
Here is my deployment.yaml:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: elastalert
  labels:
   app: elastalert
spec:
  replicas: 1
  selector:
    matchLabels:

        image: jertel/elastalert2:latest

          defaultMode: 256
          name: elastalert-config
          optional: false
        name: elastalert-config

and here is my config.yaml (the same that I used in order to try to start the container):

apiVersion: v1
data:
  config.yaml: |-
    rules_folder: /opt/rules/

    buffer_time:
      minutes: 5

    run_every:
      minutes: 5

    es_host: my-es-host
    es_port: 9200
    es_conn_timeout: 60

    scan_subdirectories: false

    writeback_index: elastalert_ops-elastalert

    disable_rules_on_error: false
kind: ConfigMap
metadata:
  name: elastalert-config

Any help and suggestion will be very appreciate.

If the documentation is flawed, you can pull request and fix it!

There is no law that you shouldn't make a pull request

I was just asking for some support/suggestion.
Thank you.

Since it was not added recently, it may be the procedure that worked at that time, but it is not the procedure that works at the moment. I don't know the reason. I don't care about that. You've just shown the steps to work.

I am not seeing this behavior. Below is my output, before it complains about my missing rules folder:

elastalert2 (master)$ grep "es_host:" config.yaml 
es_host: 172.17.0.1
elastalert2 (master)$ docker run --rm -it -v $(pwd)/config.yaml:/opt/elastalert/config.yaml jertel/elastalert2
Reading Elastic 6 index mappings:
Reading index mapping 'es_mappings/6/silence.json'

Reading index mapping 'es_mappings/6/elastalert_error.json'
New index elastalert_status created
Done!

When troubleshooting Docker and Kubernetes issues like this I suggest debugging the problem by setting --entrypoint bash in the docker run cmd line (or the appropriate entrypoint setting in your Kubernetes configuration), and then docker exec (or kubectl exec into the running container and cat the /opt/elastalert/config.yaml configuration file. You'll usually spot a problem such as the mapped file doesn't exist, but sometimes you might spot something else such as a typographical error.
