Docker container keeps randomly stopping. Can anyone help?

[roman-tasi]

I am running this command to create and run a docker container in a CentOS VM:
docker run -d -v /etc/elastalert/elastalert.yaml ghcr.io/jertel/elastalert2/elastalert2

My container starts and I can see it running with the docker ps command. However after a few minutes the container is no longer present in the docker ps command. I have used the docker start command to start the container back up, but still after a few minutes it stops again. Also this is the log from the docker logs command:

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 224, in main host = args.host if args.host else input('Enter Elasticsearch host: ') EOFError: EOF when reading a line Enter Elasticsearch host:

So obviously it seems there is an issue with the Elasticsearch host. However my config file is specifying my Elasticsearch host, so I am a bit confused.

Your -v parameter is incorrect. Please see the documentation, specifically the section that covers how to run ElastAlert 2 in a Docker container.

Thank you...

So for my -v parameter, will this work: -v /etc/elastalert/elastalert.yaml:/opt/elastalert/config.yaml ?
Keep in mind that /opt/elastalert/config.yaml does not exist on my VM.

[jertel]

Yes, that will work. The -v param will project the elastalert.yml onto that path that you specify on the right side of the colon character.

@jertel I have the same Problem.
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:

  selector:

        image: jertel/elastalert2:latest
        imagePullPolicy: IfNotPresent
        volumeMounts:
          - mountPath: /opt/config/
            name: elastalert-config
      volumes:

          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.
