one more thing we forgot to do in #617 , otherwise API server won't bootstrap on cloud:

• add melisearch container in the other api/oracle-cloud/docker-compose.yml file:

  meilisearch:
    image: getmeili/meilisearch:latest
    ports:
      - "7700:7700"
    volumes:
      - /home/ubuntu/app-data/api/meilisearch_db:/data.ms
    environment:
      MEILI_NO_ANALYTICS: true
      MEILI_MASTER_KEY: "default"

• add api/meilisearch_db to .gitignore

annnnd one last thing (i promise)

in both docker-compose files, the volume is not correct, should change data.ms to meili_data
