How to run Consul on a docker with the source data of a key-value pair?

Question

I am trying to start a Consul server on a docker container and use it as a configuration server for a SpringBoot cloud application. For this, I want to have pre-configured data (Key-Value pairs) in Consul.

My current configuration in the docker-compose.yml file is:

  consul:
    image: "progrium/consul:latest"
    container_name: "consul"
    ports:
      - '9330:8300'
      - '9400:8400'
      - '9500:8500'
      - '9600:53'
    command: "-server -bootstrap -ui-dir /ui"

Is there a way to pre-populate key-value pairs?
