Running Kibana in Docker image gives Non-Root error - docker

Question

I'm having issues attempting to setup the ELK stack (v7.6.0) in docker using Docker-Compose.
Elastic Search & Logstash startup fine, but Kibana instantly exists, the docker logs for that container report:
Kibana should not be run as root. Use --allow-root to continue.
the docker-compose for those elements looks like this:
elasticsearch:
image: docker.elastic.co/elasticsearch/elasticsearch:7.6.0
environment:
- discovery.type=single-node
ports:
- 9200:9200
mem_limit: 2gb
kibana:
image: docker.elastic.co/kibana/kibana:7.6.0
environment:
- discovery.type=single-node
ports:
- 5601:5601
depends_on:
- elasticsearch
logstash:
image: docker.elastic.co/logstash/logstash:7.6.0
ports:
- "5000:5000/tcp"
- "5000:5000/udp"
- "9600:9600"
mem_limit: 2gb
depends_on:
- elasticsearch
How do I either disable the run as root error, or set the application to not run as root?

Answer 1

In case you don't have a separate Dockerfile for Kibana and you just want to set the startup arg in docker-compose, the syntax there is as follows:
kibana:
container_name: kibana
image: docker.elastic.co/kibana/kibana:7.9.2
ports:
- 5601:5601
depends_on:
- elasticsearch
environment:
- ELASTICSEARCH_URL=http://localhost:9200
networks:
- elastic
entrypoint: ["./bin/kibana", "--allow-root"]
That works around the problem of running it on a Windows Container.
That being said, I don't know why Kibana should not be executed as root.

i've just run this docker image and all works perfectly, i share my docker-compose file:
version: '3.7'
services:
elasticsearch:
image: docker.elastic.co/elasticsearch/elasticsearch:7.6.0
container_name: elasticsearch
environment:
- node.name=node
- cluster.name=elasticsearch-default
- bootstrap.memory_lock=true
- discovery.type=single-node
- "ES_JAVA_OPTS=-Xms1g -Xmx1g"
ports:
- "9200:9200"
expose:
- "9200"
networks:
- "esnet"
kibana:
image: docker.elastic.co/kibana/kibana:7.6.0
container_name: kibana
ports:
- "5601:5601"
expose:
- "5601"
networks:
- "esnet"
depends_on:
- elasticsearch
logstash:
image: docker.elastic.co/logstash/logstash:7.6.0
ports:
- "5000:5000/tcp"
- "5000:5000/udp"
- "9600:9600
depends_on:
- elasticsearch
networks:
- "esnet"

I had the same problem. I did run it manually by adding the ENTRYPOINT to the end of Dockerfile.
ARG ELK_VERSION
FROM docker.elastic.co/kibana/kibana:${ELK_VERSION}
ENTRYPOINT ["./bin/kibana", "--allow-root"]
The docker-compose.yml
version: '3.2'
