How to Make Docker Compose Use Same Running Instance?

Hi again, so if there is anyone who see this question and look for guidance, I took the foolowing approach. I build and upload the container in the first step and then deploy it with docker-compose up. Dockerfile does the app build and test during the first step. So its like pipeline inside pipeline.

steps:
    - label: "Create container build"
      command: ./devops/cd/image.sh
      env:
        NODE_ENV: production
        CONTAINER_CONN_STR: ghcr.io/path/to/repo

    - wait

    - label: "Deploy"
      command: ./devops/cd/deploy.sh
      concurrency: 1
      concurrency_group: 'path/to/repo/deploy'
      env:
        NODE_ENV: production
        CONTAINER_CONN_STR: ghcr.io/path/to/repo
        APP_PORT: 3030

Dockerfile runs build and test stages:

FROM node:18-alpine3.17 as build

RUN ...

FROM build as test

RUN ...

FROM test as prod

RUN ...

CMD npm run fetch-env && npm run prod
