When I do a docker volume inspect on a Mac, I can see the path to the data, this appears as a /var/lib/docker/volumes/
for example, you create a Volume with a File Docker-Compose.yml:
...
influxdb:
image: influxdb:latest
container_name: influxdb
restart: always
ports:
- "8086:8086"
- "9092:9092"
volumes:
- type: volume
source: vol_influxdb
target: /var/lib/influxdb
...
You can't find this Volume "vol_influxdb" on your Mac, because it's in the Docker-VM. Start your Mac-Terminal an Enter:
screen /Users//Library/Containers/com.docker.docker/Data/vms/0/tty
Now you are in the Docker-VM and you can search your Volume with:
cd /var/lib/docker/volumes//_data/
