プロジェクトの歴史

OpenWhisk began as an IBM Research initiative in February 2015, according to Rodric Rabbah, who describes creating the project and leading its architecture, tooling, and runtimes. It was publicly announced in February 2016 at IBM InterConnect, launched on Bluemix and GitHub under the Apache License 2.0, and reached general availability on IBM Bluemix in December 2016 while also entering the Apache Software Foundation incubator.

The `apache/openwhisk-cli` repository was created on 3 April 2017, separating the Go-based command-line client into its own Apache repository. The GitHub README describes it as a unified tool for interacting with OpenWhisk services and documents released binaries for Linux, macOS, and Windows, plus source builds using Go and Gradle.

OpenWhisk's platform story expanded through IBM Cloud Functions, Adobe I/O Runtime, Red Hat involvement, and other deployments. Adobe's Runtime documentation states that Adobe I/O Runtime is based on Apache OpenWhisk and uses the OpenWhisk architecture to provide function-as-a-service, showing how `wsk`-style interaction fits into larger hosted serverless offerings even when vendors wrap or supplement the tooling.

採用の歴史

OpenWhisk adoption has been strongest among cloud/serverless platforms and self-hosted open-source serverless users rather than as a general-purpose programming language tool. The Apache homepage describes OpenWhisk as deployable locally or on cloud container infrastructure, with Kubernetes and Helm emphasized for developer and operator convenience.

The CLI's adoption follows the platform. Apache documentation names the OpenWhisk CLI as one of the key tools alongside the REST API, deployment utility, and language clients, and explicitly documents Homebrew installation for Linux or macOS. That makes `brew:wsk` the package-manager route for users who need the stock Apache client rather than a vendor-specific wrapper.

使われ方

Before use, the CLI is configured with an API host and authentication key. Apache documentation shows `wsk property set --apihost API_HOST --auth AUTH_KEY --namespace guest`, and states that the CLI stores properties in `~/.wskprops` by default unless `WSK_CONFIG_FILE` points elsewhere.

Once configured, developers use `wsk` to manage OpenWhisk actions, triggers, rules, packages, APIs, and deployment helpers. The Apache homepage frames the workflow as writing functions in supported languages, targeting an OpenWhisk instance with the CLI, and running actions in response to direct invocations, HTTP requests, schedules, or external events.

パッケージ好きにとっての重要性

`wsk` is package-nerd significant because it is the portable client binary for an Apache serverless control plane. Package managers turn the platform's API into a normal local tool that can be installed in shells, CI images, tutorials, and operator workstations.

The CLI also captures a historical moment in serverless tooling: early function-as-a-service systems needed standalone clients that could point at hosted cloud endpoints or local developer deployments. `wsk` remains the recognizable command name for Apache OpenWhisk even when surrounding products such as IBM Cloud Functions or Adobe I/O Runtime add their own layers.
