Today, the Cloud Native Computing Foundation (CNCF) accepted Harbor, a cloud native registry, into the CNCF Sandbox, a home for early stage and evolving cloud native projects.

Project Harbor is an open source cloud native registry that stores, signs, and scans content. Created at VMware, Harbor extends the open source Docker Distribution by adding the functionalities usually required by users – such as security, identity, and management – and supports replication of images between registries. With more than 4,600 stars on GitHub, the project also offers advanced security features such as vulnerability analysis, role-based access control, activity auditing, and more.

“Container registries are essential to healthy cloud native environments, and enterprises require the security, features, flexibility, and portability that a trusted registry provides,” said Haining Henry Zhang, Technical Director, Innovation and Evangelism, at VMware, and Harbor project founder. “We’re thrilled to have Harbor in an neutral home that fosters open collaboration, which is incredibly important for creating new critical features. The project will benefit greatly from the contributions of CNCF’s thriving community.”

Harbor users include CNCF members Caicloud, China Mobile,, Pivotal, Rancher, Tencent Cloud, Tenxcloud and Wise2c, along with OnStar Shanghai, Talking Data and TrendMicro, among others.

TOC sponsors of the project include Quinton Hoole and Ken Owens.
