Trying to pull quay.io/libpod/busybox:latest. Reload and use it from another podman]# podman volume podman]# podman run -it -v test_othernode:/test quay.io/libpod/busybox More details:Ĭreate from one ~]# podman volume create -driver convoy test_othernode Set up two host using one volume plugin convoy and use podman volume reload to get the volume created in another host, the volume can be get and used as expected. The volume create/delete for this plugin will be sent to the driver directly. If the same volume is reported by two plugins, the remove of the volume has to be done by specifying the driver.Ī mechanism to discover the volumes from the plugin via podman volume refresh/reloadĪ option to bypass the database for a plugin. Even in case of docker the behavior is indeterministic, if two drivers report the same volume. Presence of same volume name in two different plugin can be an invalid configuration or a corner case and the behavior can be defined and handled accordingly. Not supporting this use case would make it difficult for migration from docker to podman in those deployments. This is a must have requirement for deployment in the clustered environment. Podman should detect all the volumes seen by the volume plugin driver.ĭocker supports this configuration, where in volume available in the plugin are detected and listed. Podman can detect only volumes created locally using podman create. There are many other volume driver plugins that allow you to create a volume on third-party solutions like Azure file storage, Convoy, DigitalOcean Block. The podman running on the other node, does not detect the volume, using same custom volume driver. Create volume using custom volume driver, on shared storage, on one node of a two node cluster. Version-Release number of selected component (if applicable):ġ. This affects deployment of podman in clustered environment where the volume is created on shared storage from one node, is not detected by podman running on the other node. Set up two host using one volume plugin convoy and use podman volume reload to get. If volume is created out of band in the volume plugin, the volume is not detected by podman, unlike docker. Additional info: Docker supports this configuration, where in volume.
