cannot found /VolumeDriver.Capabilities API

[weilai201]

When I create volume by used docker api docker volume create -d convoy --opt o=size=1GB bus3 i get the response

DEBU[2514] Handle plugin get volume: POST /VolumeDriver.Get pkg=daemon DEBU[2514] Request from docker: &{bus3 map[]} pkg=daemon DEBU[2514] Response: { "Err": "Could not find volume bus3." } pkg=daemon DEBU[2514] Handle plugin create volume: POST /VolumeDriver.Create pkg=daemon DEBU[2514] Request from docker: &{bus3 map[o:size=1GB]} pkg=daemon DEBU[2514] Create a new volume bus3 for docker pkg=daemon DEBU[2514] event=create object=volume opts=map[VolumeIOPS:0 PrepareForVM:false Size:0 BackupURL: VolumeName:bus3 VolumeDriverID: VolumeType:] pkg=daemon reason=prepare volume=bus3 DEBU[2514] Created volume event=create object=volume pkg=daemon reason=complete volume=bus3 DEBU[2514] Created volume for docker bus3 pkg=daemon DEBU[2514] Response: {} pkg=daemon ERRO[2514] Handler not found: POST /VolumeDriver.Capabilities pkg=daemon DEBU[2514] Handle plugin volume path: POST /VolumeDriver.Path pkg=daemon DEBU[2514] Request from docker: &{bus3 map[]} pkg=daemon DEBU[2514] event=mountpoint object=volume pkg=daemon reason=prepare volume=bus3 DEBU[2514] event=mountpoint mountpoint= object=volume pkg=daemon reason=complete volume=bus3 DEBU[2514] Volume: bus3 is mounted at for docker pkg=daemon DEBU[2514] Response: {} pkg=daemon bus3 [root@nginx log]# docker volume create -d convoy --opt o=size=1GB bus3 DEBU[2517] Handle plugin get volume: POST /VolumeDriver.Get pkg=daemon DEBU[2517] Request from docker: &{bus3 map[]} pkg=daemon DEBU[2517] event=mountpoint object=volume pkg=daemon reason=prepare volume=bus3 DEBU[2517] event=mountpoint mountpoint= object=volume pkg=daemon reason=complete volume=bus3 DEBU[2517] Found volume bus3 for docker pkg=daemon DEBU[2517] Response: { "Volume": { "Name": "bus3" } } pkg=daemon bus3

I guess ,is convoy cannot supported '/VolumeDriver.Capabilities' api? I use nfs do for base storage.

VERSION INFO

OS version: CentOS Linux release 7.3.1611 (Core) docker verion: 1.13.0 convoy version: v0.5.0

Currently, it doesn't support Capabilities API, we can add that later.

BTW, for NFS, I don't think we have a way to limit the size of volume...

Hello

I used losetup to set the /dev/loop0 and /dev/loop1:

truncat -s 500m data.vol truncat -s 100m metadata.vol losetup /dev/loop0 data.vol losetup /dev/loop1 metadata.vol

convoy daemon start success with command

convoy daemon --drivers devicemapper --driver-opts dm.datadev=/dev/loop0 --driver-opts dm.metadatadev=/dev/loop1

but when I start container with command

docker run --name test-convoy --volume-driver devicemapper -v v1:/v1 -idt ubuntu bash

I got the error then start failed:

thanks!

[imyoungyang]

the volume-driver should be convoy, instead of devicemapper

You need to change your command: docker run --name test-convoy --volume-driver=convoy -v v1:/v1 -idt ubuntu bash

The /VolumeDriver.Capabilities part was fixed in 0.5.1.
