I deployed a web app in a rancher service and started several instance, when upgrade the rancher service, the next instance will start to stop and the previous are still initiating.
For example, If i started two instance in a service, all of instance can’t provide service while rancher service upgrading. because the first instance are initiating and the other one was stopped.
So, how can i upgrade the instance one by one when upgrade the service ?
ps: the fowlloing method does’t work
