Loading Elasticsearch from a config file in Docker

Question

Hi i'm new to elasticsearch and docker so forgive me if this question is a bit basic.

I want to load up an elasticsearch container (using the official elasticsearch image on dockerhub) with a config file on my host machine

currently what I do is

docker run -d elasticsearch elasticsearch -Des.cluster.name="testcluster1" -Des.node.name="node1"

and so on.

is there a way to load the container using a confi file i.e the elasticsearch.yml file from my host machine?

host machine is running centos (not sure if relevant but thought i'd add it just incase)

Thank you

You can do research on ONBUILD in Dockerfile.

If one line is marked with ONBUILD, it will only be triggered when run the container.

$ cat Dockerfile

FROM elasticsearch

ONBUILD ADD elasticsearch.yml /SOME_PATH

ENTRYPOINT ["/docker-entrypoint.sh"]

CMD ["elasticsearch"]

Secondly, you can also mount a host folder when run the container.

docker run -d -v "$PWD/config":/usr/share/elasticsearch/config elasticsearch -Des.cluster.name="testcluster1" -Des.node.name="node1"

I thought docker compose was to load multiple application / containers at a time and have them talk to eachother? i'm currently looking to load only 1 container but have the application in the container use a config file from my host machine
