Error while installing ror plugin inside docker container

I am trying to install readonlyrest plugin for elasticsearch inside docker container, but i am getting an error while building the image.

Error

Dockerfile

FROM docker.elastic.co/elasticsearch/elasticsearch:8.5.1

ENV ES_VERSION=8.5.1

COPY ./elasticsearch.yml config/

RUN bin/elasticsearch-plugin install -b "https://api.beshu.tech/download/es?esVersion=${ES_VERSION}"
RUN jdk/bin/java -jar plugins/readonlyrest/ror-tools.jar patch

ENTRYPOINT [ "bin/elasticsearch" ]

Can anyone help me resolve this issue?

[Mateusz Kołodziejczyk]

please try this:

FROM docker.elastic.co/elasticsearch/elasticsearch:8.5.2

ENV ES_VERSION=8.5.2

COPY ./elasticsearch.yml config/

RUN bin/elasticsearch-plugin install -b "https://api.beshu.tech/download/es?esVersion=${ES_VERSION}"

USER root
RUN jdk/bin/java -jar plugins/readonlyrest/ror-tools.jar patch
USER elasticsearch

ENTRYPOINT [ "bin/elasticsearch" ]

⚠️IMPORTANT: for Elasticsearch 8.3.x or newer, the patching operation requires root user privileges.
