Hi, I have the following situation:
- Primary container (using volumes from sidekick)
- Sidekick container, start once (only supplies data volumes to primary)
From the UI I can upgrade only the primary and reuse the volumes from the sidekick. I have been trying to achieve the same using rancher-compose. But can not get it to work.
I have made a rancher-compose file only specifying the primary service and volumes_from “sidekick”. But when I run this through rancher-compose I always get an upgraded primary with new volumes instead of the volumes from the “sidekick”.
The Dockerfile for the primary also specifies volumes at the same mount point so I assume this is used and the volumes_from is completely ignored.
Here are the files I use
Create rancher-compose file
version: '2' services: data: container_name: data image: tianon/true volumes: - /var/data labels: io.rancher.container.start_once: true server: extends: file: server.yml service: server volumes_from: - data labels: io.rancher.sidekicks: data
Upgrade rancher-compose file
version: '2' services: server: extends: file: server.yml service: server volumes_from: - data
Any help is appreciated,
