Tool for deploying new versions of some of my personal projects. Namely:
These projects are both single JVM services that simply require reverse-proxying. That's all this tool supports right now, but I hope to expand it to cover my other deploy needs.
This tool:
- picks a free port,
- starts up a new instance of the service in a screen session,
- waits for it to become healthy (responds with a 200 to a request for the home page),
- updates the Caddy configuration to reverse-proxy to the new instance, and
- shuts down the old instance.
In the directory you run the tool from, there must be a file called caddy-config.edn.
This file should contain the following information:
:name: the name of the app. Used to name thescreensession and the logger in the Caddy config:host: the domain the app is hosted on.
Then run the tool, passing the path to the new jar as an argument.
