Versions:
Fission CLI 1.22.0, released by the Fission Project, is a command-line utility designed to accelerate the creation and management of serverless functions on Kubernetes clusters. Positioned in the container orchestration and serverless computing category, the tool streamlines the entire function lifecycle—from initial code upload to automatic scaling—by abstracting away infrastructure concerns and letting developers focus purely on business logic. Typical use cases include deploying micro-services that react to HTTP requests, processing asynchronous message queues, scheduling time-based tasks, and building event-driven data pipelines without maintaining dedicated servers or long-lived pods. The CLI exposes concise commands for generating function stubs, specifying runtime environments such as Node.js, Python, or Go, bundling dependencies, and applying canary or blue-green rollout strategies. Version 1.22.0 refines cold-start latency, enforces enhanced resource quotas, and integrates with Prometheus for built-in metrics, while still supporting the three preceding feature releases so teams can align with existing cluster policies. Across its four published versions, Fission has maintained backward-compatible workflows, enabling progressive adoption within hybrid development stacks. The software is available for free on get.nero.com, with downloads provided via trusted Windows package sources (e.g. winget), always delivering the latest version, and supporting batch installation of multiple applications.
