Installing plugins with custom docker image warning message

[javadevmtl (None)]

Here is my Dockerfile...

FROM docker.elastic.co/elasticsearch/elasticsearch-platinum:6.1.1

USER root
RUN whoami
RUN /usr/share/elasticsearch/bin/elasticsearch-plugin install --batch repository-s3
RUN /usr/share/elasticsearch/bin/elasticsearch-plugin list

But I get...

Step 4/4 : RUN /usr/share/elasticsearch/bin/elasticsearch-plugin install --batch repository-s3
---> Running in a9ced61590de
-> Downloading repository-s3 from elastic

Is it an issue?

No, it's warning you that the plugin requires security manager permissions outside those that are granted to the core Elasticsearch server process. This is normal behavior (that these warnings are presented when a plugin requires additional permission grants).
