Ingest-attachment plugin installation within Dockerfile

Elastic Stack Elasticsearch
1

In order to install ingest-attachment plugin to a official elasticsearch docker image, here the Dockerfile to use:

FROM docker.elastic.co/elasticsearch/elasticsearch:6.7.0
RUN /usr/share/elasticsearch/bin/elasticsearch-plugin install --batch ingest-attachment

but after build the command curl -X GET 'http://elasticsearch:9200/_cat/plugins' returns nothing.

When the plugin is installed manually, it seems the installation succeeds in spite of the warnings:

# bin/elasticsearch-plugin install -b ingest-attachment
-> Downloading ingest-attachment from elastic

Why this warnings? How to check if the plugin is properly installed?

I think that you need to stop elasticsearch service and restart it. Because I think that this line:

FROM docker.elastic.co/elasticsearch/elasticsearch:6.7.0

Assumes that the service is already started.

As regards the warnings, could they be related to the jdk version? (if is too new or too old)
Is there any recommandation?

I figured out how to check if plugin is installed:

    [root@6397b9ae1ad9 elasticsearch]# elasticsearch-plugin list
    ingest-attachment
