Upgrade the cloud components to the desired version, it uses helm to upgrade the installed release of cloudcore chart, which includes all the cloud components

Usage:
  keadm upgrade cloud [flags]

Flags:
      --advertise-address string    Please set the same value as when you installed it, this value is only used to generate the configuration and does not regenerate the certificate. eg: 10.10.102.78,10.10.102.79
  -d, --dry-run                     Print the generated k8s resources on the stdout, not actual execute. Always use in debug mode
      --external-helm-root string   Add external helm root path to keadm
      --force                       Forced upgrading the cloud components without waiting
  -h, --help                        help for cloud
      --kube-config string          Use this key to update kube-config path, eg: $HOME/.kube/config (default "/root/.kube/config")
      --kubeedge-version string     Use this key to set the upgrade image tag
      --print-final-values          Print the final values configuration for debuging
      --profile string              Sets profile on the command line. If '--values' is specified, this is ignored
      --reuse-values                reuse the last release's values and merge in any overrides from the command line via --set and -f.
      --set stringArray             Sets values on the command line (can specify multiple or separate values with commas: key1=val1,key2=val2)
      --values stringArray          specify values in a YAML file (can specify multiple)

# 修改/lib/systemd/system/edgecore.service，将环境变量DEPLOY_MQTT_CONTAINER设置成false
# 这步可以放在更新EdgeCore前修改，这样就不用重启EdgeCore了
