Rolling Restart for CF
CF plugin for zero downtime application restarts.
This was made to fill a the gap in zero-downtime restarts for the PCF CLI. It will restart your application one instance at a time until each instance is up. The plugin should provide feedback through the CLI through the whole process.
Installation
Download the latest version from the releases page and make it executable.
$ cf install-plugin path/to/downloaded/binary
Usage
$ cf rolling-restart [--max-cycles #] APP_NAME
The alias rrs
also exists for a shorthand (Ex. cf rrs APP_NAME
).
The flag --max-cycles
augments the number of times the plugin will check to see if the app is up. The default is 120
cycles which roughly equate to ~2 minutes. Each cycle consists of checking the current state of the recently restarted instance and then pausing 1 second until the instance is running or the max cycles have been reached.
