Private container registry support for Gitpod Flex

We’re excited to announce that Gitpod Flex now supports Container Registry Secrets, allowing you to securely authenticate with private container registries.

With Container Registry Secrets, you can now:

• Pull Dev Container images from private registries
• Authenticate with container registries during your development workflow
• Work with private images in your Flex environment without exposing credentials

This feature supports all major container registries using basic authentication, including:

• Docker Hub
• GitHub Container Registry
• GitLab Container Registry
• Azure Container Registry

Setting up Container Registry Secrets is straightforward through the Project Secrets interface. You’ll need to provide the registry hostname, username, and password/token to create the authentication secret.

Learn how to set up and use Container Registry Secrets in our documentation.

Note: This initial release supports basic authentication only. Support for AWS ECR and other authentication methods will be coming in future updates.
