Hoping for some help with a novice please.
My aim here is just to have somewhere I can easily reference where i'm storing the data as I add more and more stacks.
in Portainer (BE 2.19.1) I’ve created a volume called ‘my_data'. When I look at Portainer volumes it has in the mount point ‘/var/lib/docker/volumes/my_data/_data’. So thats where I've put some of the config files and other persistent data I want to use.
I want to use the ‘my_data’ Volume in multiple stacks (using docker compose) as the persistent data storage. I thought I’d be able to say in my compose:
volumes:
`- my_data/changedetection/datastore:/datastore`
However this gives the error:
failed to deploy a stack: service "changedetection" refers to undefined volume my_data/changedetection/datastore: invalid compose project
- Do I need to have one Volume for every stack so I would just say
my_data:/datastore?
- Am I better off just ignoring Volumes and putting my persistent files somewhere like /data/my_data/ ?
- Am I asking the wrong questions :)
