Simplify your DevOps processes by using a private container registry fully managed by Docker. IONOS takes care of all the important steps, from configuration to maintenance to security patches. This allows you to focus on managing the workloads within your CI/CD environment.

With IONOS, you’ll have UK GDPR-compliant hosting in an ISO certified European data centre. Our data centres are internationally accessible and optimised for international teamwork.

Based on an open-source platform and controllable via the IONOS application programing interface (API), we ensure full interoperability as well as flexibility in processing your Docker images. Your data will be securely backed up in our scalable storage and fully integrated into the IONOS Cloud Compute Engine.

The private container registry is easy to manage from your IONOS Cloud account and due to the geographical proximity to your Kubernetes clusters, it always has low latency.

Maximum security through role-based access control, including authentication

The functionality and security of your applications is our main concern. That's why our experts continue to work on the development of patches and system backups based on modern technology.

Additionally, we have developed a multi-dimensional system to ensure both the integrity of the platform and the efficient handling of your applications:

  • The entire infrastructure of the private container registry is designed as a high-availability configuration, i.e., redundantly secured and UK GDPR-compliant
  • All data is stored using SSD data at rest encryption
  • All resources can be used and managed with a granular system of roles and access rights
  • Access via a public internet connection is possible, but requires additional authentication to view, download or retrieve images
