Question: Is there an easy way to upgrade all Cronicle hosts in a cluster? about cronicle HOT 3 CLOSED

Hey there,

Don't worry, the API is fully backward compatible. You can have mismatched versions across your cluster and everything will be fine. I won't make any breaking API changes like that until v2.0 or later, and I'll make sure there is a very clear and easy upgrade path when the time comes.

Upgrading a Cronicle server is very easy -- it's just one single command. This also automatically shuts down and restarts the service as well:

/opt/cronicle/bin/control.sh upgrade

Just enter that one command on all your servers and you'll be on the latest version. You can also do it in any order -- Cronicle will reconnect all the servers when they come back online.

At some point in the future I'll add a button to do this from the UI. And I'll display the current version number for each server as well (thanks for that feature request!).

Hope this helps!

You're awesome @jhuckaby. Thanks!

In the UI, you can create an event with 'Multiplex' type so it runs on all servers and then do something like this:

nohup /opt/cronicle/bin/control.sh upgrade >/dev/null 2>&1 &

Running this event will trigger the upgrade on all servers (you won't see it in the logs though).
