Adds: - `kamal upgrade` to upgrade all app hosts and accessory hosts - `kamal proxy upgrade` to upgrade the proxy on all hosts - `kamal accessory upgrade [name]` to upgrade accessories on all hosts Upgrade takes rolling and confirmed options and calls `proxy upgrade` and `accessory upgrade` in turn. To just upgrade a single host add -h [host] to the command. But the upgrade should run on all hosts, not just those running the proxy. Calling upgrade on a host that has already been upgraded should work ok. Upgrading hosts causes downtime but you can avoid if you run multiple hosts by: 1. Implementing the pre-proxy-reboot and post-proxy-reboot hooks to remove the host from external load balancers 2. Running the upgrade with the --rolling option **kamal proxy upgrade** 1. Creates a `kamal` network if required 2. Stops and removes the old proxy (whether Traefik or kamal-proxy) 3. Starts a kamal-proxy container in the `kamal` network 4. Reboots the app containers in the `kamal` network **kamal accessory upgrade [name]** 1. Creates a `kamal` network if required 2. Reboots the accessory containers in the `kamal` network A matching `downgrade` command will be added to Kamal 1.9.
