- Harbor介绍
Docker容器应用的开发和运行离不开可靠的镜像管理,虽然Docker官方也提供了公共的镜像仓库,但是从安全和效率等方面考虑,部署我们私有环境内的Registry也是非常必要的。Harbor是由VMware公司开源的企业级的Docker
Registry管理项目,它包括权限管理(RBAC)、LDAP、日志审核、管理界面、自我注册、镜像复制和中文支持等功能。
官网地址:https://github.com/goharbor/harborDocker Harbor是一个企业级的Docker Registry服务,旨在提供安全、可靠的镜像存储和管理解决方案。以下是Docker
Harbor的一些关键特点:
- 私有Registry:Docker Harbor允许用户搭建私有的Docker Registry,使得企业可以在自己的内部网络中安全地存储和管理Docker镜像。
- 安全性:Docker Harbor提供了访问控制、用户和团队管理功能,以确保镜像的安全性。它支持用户身份验证、权限控制、安全扫描等功能,帮助用户保护他们的容器镜像不受未经授权的访问。
- 可扩展性:Docker Harbor支持集群部署,可以轻松地扩展以应对大规模的容器镜像存储需求。
- 镜像复制和同步:Docker Harbor允许用户在不同的Registry之间复制和同步镜像,方便用户在多个部署环境之间共享和管理镜像。
- 审计和日志记录:Docker Harbor提供审计和日志记录功能,记录用户对镜像的操作,以帮助用户跟踪镜像的变更历史。 总的来说,Docker Harbor是一个功能强大的企业级Docker
Registry服务,为用户提供了安全、可靠的方式来管理和存储Docker镜像。
