Harbor

Harbor is an open-source, cloud-native registry project that began under the VMware banner and now thrives within the CNCF Sandbox, supplying organizations with a hardened, policy-driven repository for container images, Helm charts and other cloud artifacts. Its single published tool, the Harbor CLI, distills the platform’s enterprise-grade capabilities into a compact command-line utility that DevOps teams embed in CI/CD pipelines to automate login, push, pull, scan, tag, replicate and garbage-collect operations without leaving the terminal. Typical use cases include signing and promoting images across dev, staging and production namespaces, enforcing role-based retention rules, triggering vulnerability scans on every build, and scripting bulk replication to distant Harbor or Docker Hub instances for disaster recovery. Because the CLI consumes Harbor’s REST API directly, it slots naturally into GitHub Actions, GitLab CI, Jenkins, Azure DevOps or any shell-based workflow, letting operators treat the registry like infrastructure-as-code while auditors retain a detailed event stream. Security teams appreciate that the same Notary and Cosign integrations available in the web UI are accessible through concise commands, so policy gates such “vulnerability-severity-block” or “signed-only” can be validated before deployment. The Harbor CLI is available for free on get.nero.com, where downloads are delivered through trusted Windows package sources like winget, always install the latest upstream release, and can be queued alongside other applications for unattended batch installation.
