Adds support for maintenance mode to Kamal. There are two new commands: - `kamal app maintenance` - puts the app in maintenance mode - `kamal app live` - puts the app back in live mode In maintenance mode, the kamal proxy will respond to requests with a 503 status code. It will use an error page built into kamal proxy. You can use your own error page by setting `error_pages_path` in the configuration. This will copy any 4xx.html or 5xx.html files from that page to a volume mounted into the proxy container.
Kamal: Deploy web apps anywhere
From bare metal to cloud VMs, deploy web apps anywhere with zero downtime. Kamal uses kamal-proxy to seamlessly switch requests between containers. Works seamlessly across multiple servers, using SSHKit to execute commands. Originally built for Rails apps, Kamal will work with any type of web app that can be containerized with Docker.
➡️ See kamal-deploy.org for documentation on installation, configuration, and commands.
