Want to use Elasticsearch as a base image

ANUBHAV_GUPTA · April 19, 2023, 10:17am

I want to use elasticsearch app as a base image and load a json file while booting up the ES instance.
Can I do this?
What will be the Entrypoint to start the container?

I think it's this one:

github.com

elastic/elasticsearch/blob/8.7/distribution/docker/src/docker/bin/docker-entrypoint.sh

#!/bin/bash
set -e

# Files created by Elasticsearch should always be group writable too
umask 0002

# Allow user specify custom CMD, maybe bin/elasticsearch itself
# for example to directly specify `-E` style parameters for elasticsearch on k8s
# or simply to run /bin/bash to check the image
if [[ "$1" == "eswrapper" || $(basename "$1") == "elasticsearch" ]]; then
  # Rewrite CMD args to remove the explicit command,
  # so that we are backwards compatible with the docs
  # from the previous Elasticsearch versions < 6
  # and configuration option:
  # https://www.elastic.co/guide/en/elasticsearch/reference/5.6/docker.html#_d_override_the_image_8217_s_default_ulink_url_https_docs_docker_com_engine_reference_run_cmd_default_command_or_options_cmd_ulink
  # Without this, user could specify `elasticsearch -E x.y=z` but
  # `bin/elasticsearch -E x.y=z` would not work. In any case,
  # we want to continue through this script, and not exec early.
  set -- "${@:2}"
else

BUT: why not using docker compose instead?

So you just use the normal image and when it's ready to run, run another container which do some curl calls...

Want to use a single container only.
Basically What I am trying to do is this:-
Using elasticsearch as base image and then passing a json file inside the container in order to boot the elasticsearch with the json data index.

Why do you want to use a single container? The "loader" container should run only for few seconds. What's the value of adding another step within the Elasticsearch service?

I need to run a python script for loading a json file data in ES while it's booting up.
So that, I can have the ES instance running with preloaded index.

Yes but this does not answer my question.
But anyway. I gave you I believe the script which is called by the docker image.

Maybe I won't be able to explain you that.
But since you understood the usecase, Is it possible for me to do this in same container?
Otherwise using docker-compose is the obvious solution that can work.

I don't know. May be by modifying the docker-entrypoint.sh but I'm really unsure on how this would work. You would need to change last line, make it a daemon and wait until the service is ready to load your documents and then wait forever to make sure the container does not stop...

But honestly I don't know if this will work.
