Manage Data in Docker to use external volume. Your volumes are stored in a part of the host filesystem which is managed by Docker (/var/lib/docker/volumes/ on Linux). The description of bind mounts was not very clear to me and I had to use other sources.
Example of docker-compose.yml
I use Redis as a cache storage on some projects. Sometimes it is necessary to store the data on an external directory or a mounted volume, so I would show the details below as an example.
version: "3.7" services: redis: container_name: redis image: redis:5.0.14-alpine command: ["redis-server", "--appendonly", "yes"] volumes: - redis_data:/data networks: - redis_net deploy: replicas: 1 restart_policy: condition: on-failure healthcheck: test: ["CMD-SHELL", "redis-cli", "ping"] interval: 1m timeout: 10s retries: 3 start_period: 60s networks: redis_net: volumes: redis_data: driver: local driver_opts: type: none o: bind device: '/mnt/volume_01/docker_redis_data'
When I raised the issue, I thought of a simpler configuration setting, but in the end, it didn’t.
