Harbor

|Community Meeting| |------------------| |The Harbor Project holds bi-weekly community calls in two different timezones. To join the community calls or to watch previous meeting notes and recordings, please visit the meeting schedule.|

Note: The main branch may be in an unstable or even broken state during development. Please use releases instead of the main branch in order to get a stable set of binaries.

Harbor is an open source trusted cloud native registry project that stores, signs, and scans content. Harbor extends the open source Docker Distribution by adding the functionalities usually required by users such as security, identity and management. Having a registry closer to the build and run environment can improve the image transfer efficiency. Harbor supports replication of images between registries, and also offers advanced security features such as user management, access control and activity auditing.

Harbor is hosted by the Cloud Native Computing Foundation (CNCF). If you are an organization that wants to help shape the evolution of cloud native technologies, consider joining the CNCF. For details about who is involved and how Harbor plays a role, read the CNCF announcement.

Features

• Cloud native registry: With support for both container images and Helm charts, Harbor serves as registry for cloud native environments like container runtimes and orchestration platforms.
• Role based access control: Users access different repositories through 'projects' and a user can have different permission for images or Helm charts under a project.
• Policy based replication: Images and charts can be replicated (synchronized) between multiple registry instances based on policies with using filters (repository, tag and label). Harbor automatically retries a replication if it encounters any errors. This can be used to assist loadbalancing, achieve high availability, and facilitate multi-datacenter deployments in hybrid and multi-cloud scenarios.
• Vulnerability Scanning: Harbor scans images regularly for vulnerabilities and has policy checks to prevent vulnerable images from being deployed.
• LDAP/AD support: Harbor integrates with existing enterprise LDAP/AD for user authentication and management, and supports importing LDAP groups into Harbor that can then be given permissions to specific projects.
• OIDC support: Harbor leverages OpenID Connect (OIDC) to verify the identity of users authenticated by an external authorization server or identity provider. Single sign-on can be enabled to log into the Harbor portal.
• Image deletion & garbage collection: System administrators can run garbage collection jobs so that images (dangling manifests and unreferenced blobs) can be deleted and their space can be freed up periodically.
• Graphical user portal: User can easily browse, search repositories and manage projects.
• Auditing: All the operations to the repositories are tracked through logs.
• RESTful API: RESTful APIs are provided to facilitate administrative operations, and are easy to use for integration with external systems. An embedded Swagger UI is available for exploring and testing the API.
• Easy deployment: Harbor can be deployed via Docker compose as well Helm Chart, and a Harbor Operator was added recently as well.

Verifying Release Signatures

Starting with v2.15.0, Harbor release artifacts are cryptographically signed using Cosign to ensure authenticity and integrity.

Download the installers and signature bundles from the Harbor releases page.

Quick Verification

# Install Cosign (v2.0+)
brew install sigstore/tap/cosign

# Verify signature
cosign verify-blob \
  --bundle harbor-offline-installer-v2.15.0.tgz.sigstore.json \
  --certificate-oidc-issuer https://token.actions.githubusercontent.com \
  --certificate-identity-regexp '^https://github.com/goharbor/harbor/.github/workflows/publish_release.yml@refs/tags/v.*$' \
  harbor-offline-installer-v2.15.0.tgz

• Expected output: Verified OK
