Rancher: upgrade stack do not work !

[danlanxiaohei]

i try to upgrade stack by calling '/v1/projects/proj_id/environments/env_id/?action=upgrade' ,but it seems not work.

i want to modify the dockerCompose port from 8000 to 8002, and modify the rancherCompose scale from 1 to 2.

here is the request:
HTTP/1.1 POST /v1/projects/1a5/environments/1e37/?action=upgrade

docker-compose config

node-examle:
  restart: always
  image: "path/to/your/node-example"
  ipc: host
  privileged: true
  ports:
    - 8002:3000

rancher-compose config

node-examle:
  scale:2

however, only dockerCompose upgrade success ,the port update to 8002, but the rancherCompose scale not change ,it is still 1.

@danlanxiaohei to update the scale of the service, you have to execute this command:

rancher-compose -p stack1 scale service1=3

Upgrade command is meant to handle only container specific changes such as image update, port change, etc.

Please refer to the doc for more info:

@alena1108 If we can scale service by the upgrade api , It will keep the stack with the config in the codebase.

Shouldn't there be a way to access this functionality through the API? Preferably without having to parse out the rancher-compose file ourselves and make API calls for each service.
