Setting "RBD_CONF_POOL" not found in the plugin configuration #3

Closed seffyroff closed 6 years ago

seffyroff commented 6 years ago

upon installation with the following arguments:

docker plugin install wetopi/rbd \
  --alias=wetopi/rbd \
  LOG_LEVEL=1 \
  RBD_CONF_POOL="rbd" \
  RBD_CONF_CLUSTER=ceph \
  RBD_CONF_KEYRING_USER=client.docker

I get the following output: 

seffyroff@celery:/var/data$ docker plugin install wetopi/rbd \
>   --alias=wetopi/rbd \
>   LOG_LEVEL=1 \
>   RBD_CONF_POOL="rbd" \

The plugin installs successfully if I remove the RBD_CONF_POOL env, but if I then try to create a volume, predictably if fails with:

seffyroff@celery:/var/data$ docker volume create -d wetopi/rbd -o size=206 my_rbd_volume
Error response from daemon: create my_rbd_volume: VolumeDriver.Create: volume-rbd Name=my_rbd_volume Request=Create Message=pool option required

Adding -o pool=rbd allows me to successfully create an image:

seffyroff@celery:/var/data$ docker volume create -d wetopi/rbd -o size=206 my_rbd_volume -o pool="rbd"
my_rbd_volume
seffyroff@celery:/var/data$ docker volume ls
DRIVER              VOLUME NAME
wetopi/rbd:latest   my_rbd_volume

I see in your changelog:

Rbd pool: is a plugin config param. (changed in order to avoid the need to persist state of volumes).

Perhaps version 1.0 didn't get uploaded to the docker hub?

seffyroff commented 6 years ago

Continuing on, attempting to deploy from a compose file like this:

volumes:
  data:
    driver: wetopi/rbd
    driver_opts:
      size: 256M
      pool: rbd

Errors out like this. Looks like it's trying to talk to a Consul KV store?

Problem is you are not running the latest plugin version (our fault. makefile was pushing only with version tag)

You can check the version with a:

docker plugin inspect wetopi/rbd:latest | grep PLUGIN_VERSION

Solution:

docker plugin install wetopi/rbd:1.0.1 ... .. .
