I have used the Dockerfile from this repo [https://github.com/deviantony/docker-elk/tree/searchguard/elasticsearch](https://github.com/deviantony/docker-elk/tree/searchguard/elasticsearch)

and I have modified the dockerfile to install the search guard plugin, which looks like the following:

```auto
FROM docker.elastic.co/elasticsearch/elasticsearch:7.1.1
 
COPY config/sg/ config/sg/
COPY bin/ bin/

RUN elasticsearch-plugin install --batch com.floragunn:search-guard-7:7.1.1-35.0.0 \
    && chmod +x plugins/search-guard-7/tools/*.sh \
    && chown -R elasticsearch config/sg/ \
    && chmod -R go= config/sg/

```

Then I build the image and run it as a container using `docker run -d -p 9200:9200 es_new:latest`  
however, the container created, and it is either gone in a minute, or not go away but connect to the localhost:9200

if it is not gone, I use docker logs to view the logs, then I found that

```auto

```

after a while, the container is gone too. I have no idea what happened since I am using the code from office repo with minor modification, and How come I cannot connect to it.

you may want to ask this in the dedicated search guard forum (a completely different forum, not this one on [elastic.co](http://elastic.co)), as this looks like a plugin issue
