The execution phase the server is currently in.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Setup

The server was created, but has not started yet.

Bootstrap

Services are being prepared.

During graceful upgrades this phase acquires the listening FDs from the old process.

BootstrapComplete

Bootstrap has finished, listening FDs have been transferred.

Running

The server is running and is listening for shutdown signals.

GracefulUpgradeTransferringFds

A QUIT signal was received, indicating that a new process wants to take over.

The server is trying to send the fds to the new process over a Unix socket.

GracefulUpgradeCloseTimeout

FDs have been sent to the new process. Waiting a fixed amount of time to allow the new process to take the sockets.

GracefulTerminate

A TERM signal was received, indicating that the server should shut down gracefully.

ShutdownStarted

The server is shutting down.

ShutdownGracePeriod

Waiting for the configured grace period to end before shutting down.

ShutdownRuntimes

Wait for runtimes to finish.

Terminated

The server has stopped.
