Undeletable or persistent docker-compose volumes or data storage

is there possible to somehow create persistent storage for containers, created with docker-compose and don't remove them even when running docker-compose down -v so they will be automaticly attached to their containers after again starting the docker-compose up -d ?

Solution

  • What I usually do is to use an external volume, something like:

    $ docker volume create nodemodules

    docker-compose.yml

    version: '3.7'

services:
  frontend:
    image: node:11
    volumes:
      - nodemodules:/app/node_modules

volumes:
  nodemodules:
    external: true
