项目历史

The upstream openshift-online/ocm-cli README describes the project as command-line tools that simplify use of the OCM API. It is written and distributed as a Go CLI, with installation paths through Fedora/CentOS Copr packages, Homebrew, GitHub release binaries, and Go tooling.

The CLI follows the service model of OpenShift Cluster Manager: a managed service on Red Hat Hybrid Cloud Console used to create, operate, and upgrade OpenShift clusters. Red Hat documentation positions OCM as a unified dashboard for OpenShift Container Platform, OpenShift Dedicated, and Red Hat OpenShift Service on AWS cluster workflows.

The CLI evolved around authenticated API access. Its README documents offline access token login, OpenID token exchange through sso.redhat.com, per-user configuration files, `OCM_CONFIG` for multiple concurrent logins, keyring storage, opaque-token support, and raw API-style `get` requests.

采用历史

OCM CLI adoption is tied to Red Hat OpenShift operations rather than general Kubernetes administration. It complements the OpenShift `oc` CLI: `oc` manages cluster and application resources, while `ocm` speaks to Red Hat's cluster-manager APIs for subscription, fleet, and managed-cluster workflows.

Homebrew's formula API generated on 2026-07-01 lists stable version 1.0.15 and 620 installs over 365 days. The README's Fedora/CentOS Copr path and release-binary installation instructions show that Homebrew is only one of several distribution channels for OpenShift operators.

使用方式

A user logs in with an OpenShift Cluster Manager offline token from console.redhat.com, after which credentials are stored in an OCM configuration file or supported OS keyring. Commands can then retrieve objects, query cluster collections, print tokens for use with curl, and interact with API resources under paths such as `/api/clusters_mgmt/v1/clusters`.

The CLI is especially useful for operators who need repeatable cluster-management tasks, support workflows, or scripting against api.openshift.com without manually driving the web console.

为什么软件包爱好者会关心

OCM CLI is a vendor operations CLI with service-specific authentication, multiple native distribution channels, and a clean Homebrew formula. Its metadata helps distinguish Red Hat's cluster-manager API tooling from the separate OpenShift client binary `oc`.

时间线

• The README's installation example references release v0.1.30, reflecting the pre-1.0 release series used for binary distribution.
• Before version 0.1.56, the README says the configuration file used `~/.ocm.json`; later versions use platform-specific application configuration paths.
• 2026-07-01: Homebrew formula metadata lists stable version 1.0.15 and 620 installs over the previous 365-day analytics window.
