But i am little bit confuse on the ebs service delivered into rancher 1.3.x On the catalog i see that Rancher-ebs is available and certified. I try it to create EBS volume and attach it to a cattle service (scale=1) It work fine, but with some prerequisites: 1 - under “Infrastructure\>storage”, i need to declare each volume name (ex : volume1) with a optional key “size” which is the desired size of the EBS volume (ex: size=16) 2 - under the service, i add the volume associate to the container volume path (ex: volume1:/var/lib/mysoft 3 - once the service is “active” , i see under AWS console, that a new volume “volume1” has been created with size 16GB, and attached to the EC2 node, where the “service” is “active” Ok, now the issues that i meet: - if i try to change the node of the service, I get an error because the volume1 is attached to the current node. To solved it i go to the AWS console and force to dettach volume1. After a time, the service is “active” on the new node and volume1 reattached on it. But why rancher-ebs is not able to do it itself ? - another issue is about “snapshot”. Under API of the volume1 i see that “actions” regarding snapshot are not available. Do you l know why i cannot make snapshot ? Finally, my last question : - i found lot blog on convoy-ebs but not on rancher-ebs. But convoi-ebs does not appears on the catalog. Why ? Is it depreacated ? ---

Hi all, Just to update you about my tests. Regarding the move on a single service with EBS volume: I discover that if i stop the service , and delete the associated container, then rancher-ebs service automatically dettach the EBS volume from the EC2 . After that, i can easly move the service to another node… Cool ! But nothing about how to activate “snapshot” throwght rancher API …
