ComposeContainer mount different file and restart init container

[bilak]

Hello,
I'm using ComposeContainer to spin up some application-container (e.g. Keycloak) and then configure it by let's say init-container (keycloak-config-cli). When init-container finishes it works, it just stops with correct exit code.

example of docker-compose.yml

services:
  keycloak:
    image: quay.io/keycloak/keycloak:${KEYCLOAK_VERSION}
    command: >
      start-dev --log-level="org.keycloak:debug,org.keycloak.transaction:info,org.keycloak.services.scheduled:info"
  keycloak-config-cli:
    image: quay.io/adorsys/keycloak-config-cli:${KEYCLOAK_CONFIG_CLI_VERSION}  
    depends_on:
      - keycloak
    volumes:
      - "./config/realms:/config"

I'd like to reuse the initial state of application-container and just do some changes in init-container (e.g. mount different config files) and then start it again to do a re-configuration stuff for application-container. Is that possible with current implementation? Any hints how to do that?

thanks
