Minimize or eliminate downtime during application updates using rolling,
blue/green, or canary deployment patterns.
This section describes common patterns for updating already-running jobs
including rolling updates, blue/green deployments, and canary builds. Nomad
provides built-in support for this functionality.
Configure a Nomad job to perform rolling updates.
Configure your Nomad job for blue/green and canary deployments to more
safely update existing applications and services.
Configure the signal that Nomad sends to applications before killing them,
allowing them to drain connections or gracefully terminate.
