Look for volumes in a different location than default

[Atul-Torane]

Bug description
When I try to browse volume it is always searching volumes folder in /var/lib/docker/volume, but my docker is installed in /data1/dockerconfig/ in 2 servers and /data2/dockerconfig in remaining 6 servers.

Expected behavior
Portainer agent should browse volumes location where my docker is installed.

You can see how here

Steps to reproduce the issue:

1. Install docker in any folder except /var/lib/docker/
2. Create Volumes using UI
3. Browse created volume.

Technical details:

• Portainer version: 1.23.1
• Docker version (managed by Portainer): 18.06.0-ce
• Platform (windows/linux): Red Hat Enterprise Linux Server 7.5 (Maipo)
• Command used to start Portainer :

1. Portainer Command --> docker service create --name portainer --network portainer_agent_network --publish 9000:9000 --publish 8000:8000 --replicas=1 --constraint 'node.role == manager' portainer/portainer:1.23.1 -H "tcp://tasks.portainer_agent:9001" --tlsskipverify

2. Portainer Agent --> docker service create --name portainer_agent --network portainer_agent_network --mode global --constraint 'node.platform.os == linux' --mount type=bind,src=//var/run/docker.sock,dst=/var/run/docker.sock --mount type=bind**,src=//var/lib/docker/volumes**,dst=/var/lib/docker/volumes portainer/agent

Note : In above command if I use my docker installation volume path /data1/dockerconfig/volumes instead of ,src=//var/lib/docker/volumes, then it will not work because only 2 servers has /data1/dockerconfig/volumes path as already mention in Bug description.

Portainer is hard coded to look in var/lib/docker/volumes. When you start portainer, you can try to adjust the bind mount like -v /data1/dockerconfig:/var/lib/docker/volumes But that only lets you set on path across all nodes. Rgds, Neil Cresswell

[Atul-Torane]

is it possible that portainer agent look volumes path where my docker is installed ????

[ncresswell]

Not at present, no. That would need to be an evolution. Please open a feature request.
