Hi,
I’ve created a Stack by providing a docker-compose.yml. I see that there’s an Upgrade button next to each container, but as far as I understand how this works it’s no use - each service in compose file has a specific version assigned.
What I would like is to update the docker-compose.yml file, and redeploy (Upgrade) only those services (containers) which have new version.
Does that make any sense? 
Thanks!
What your saying makes sense but is not there. The UI has yaml import as a one-time convenience to get a stack into the UI. If you want to continually work with yaml file use the CLI/compose tools where you have tools to edit and compare them; working with yaml in a browser is not pleasant.
Ok, that’s fine, but I’m having trouble finding the docs about updating docker-compose.yml in any way, not just via UI…would you mind providing the link?
http://docs.rancher.com/rancher/v1.3/en/cattle/rancher-compose/
Download links are in the page footer (“Download CLI”)
Hm, there’s a link at the bottom of this page - http://docs.rancher.com/rancher/v1.3/en/cattle/rancher-compose/commands/ - about upgrading, but it’s 404 - http://docs.rancher.com/rancher/v1.3/en/cattle/rancher-compose/upgrading/
From what I see in the docs, I’d do something like rancher-compose up -d --upgrade, right? That would upgrade only those services for which I’ve changed stuff (version or whatever)?
