Silent (Unattended) Upgrade Method

1 minute read

You can run the CloudBees Flow upgrade in unattended (silent) mode with no user interface for either Windows or Linux.

When upgrading the nodes in a CloudBees Flow cluster, you must keep the other nodes stopped until the primary node upgrade is complete.
  1. (Linux only) Enter the following command to make the installer file executable:

    chmod +x ./CloudBees Flow-<version>
  2. Enter the following command from a command line to begin a silent upgrade:

    ./CloudBees Flow-<version> --mode silent
