Passing overrides as YML file in Docker Compose?

How do I pass overrides as YML files in Docker Compose? There's no obvious entrypoint from what I can see.

You can configure RESTHeart using a configuration override file as documented here.

To mount the override file, use the -v option in Docker, for example at /opt/restheart/etc/conf-overrides.yml. Then, specify the file with the -o RESTHeart option.

Here is an example command:

docker run --rm -p "8080:8080" -e RHO="" -v /path/to/conf-overrides.yml:/opt/restheart/etc/conf-overrides.yml softinstigate/restheart -o etc/conf-overrides.yml

NOTE:

The RESTHeart Docker image uses the RHO environment variable, which takes precedence over the configuration override file. To ensure the configuration override file is used, include -e RHO="" in your docker run command.

Does this work in a Docker Compose context?

[ujibang]

yes, you define a docker compose conf file like

services:
    restheart:
        image: softinstigate/restheart
        volumes:
            - /path/to/conf-overrides.yml:/opt/restheart/etc/conf-overrides.yml
        command: ["-o", "/opt/restheart/etc/conf-overrides.yml"] 
        ports:
            - "8080:8080"
        environment:
            RHO: ""
