This is a Go backend, sync engine, themes, and updated UI with helm OCI support. The legacy React frontend (v0.x) is available on the [0.x branch](https://github.com/eznix86/docker-registry-ui/tree/0.x).\n\n\n## Quick Start\n\nThe UI can be deployed in minutes with Docker Compose:\n\n```yaml\nservices:\n  registry-ui:\n    image: ghcr.io/eznix86/docker-registry-ui:latest\n    ports:\n      - \"8011:3000\"\n    environment:\n      - REGISTRY_URL=http://your-registry.com:5000\n      - REGISTRY_AUTH=base64basicauthhere\n```\n\nThen open the UI at: [http://localhost:8011](http://localhost:8011)\n\nFor extensive environment customization, see [`.env.example`](./.env.example).\n\n---\n\n## Deployment\n\n### Docker Compose / Swarm\n\n```yaml\nservices:\n  registry-ui:\n    image: ghcr.io/eznix86/docker-registry-ui:latest\n    ports:\n      - \"8011:3000\"\n    environment:\n      - REGISTRY_URL=http://your-registry.com:5000\n      - REGISTRY_AUTH=base64basicauthhere\n```\n\n### Kubernetes (Helm)\n\n```sh\nhelm repo add docker-registry-ui https://eznix86.github.io/docker-registry-ui\nhelm repo update\n\nhelm install docker-registry-ui docker-registry-ui/docker-registry-ui \\\n  -n docker-registry-ui \\\n  --create-namespace\n```\n\n#### Creating Registry Secrets\n\n```sh\nkubectl create secret generic registry-ui-secret \\\n  -n docker-registry-ui \\\n  --from-literal=REGISTRY_URL=\"http://your-registry.com:5000\" \\\n  --from-literal=REGISTRY_AUTH=\"$(echo -n 'username:password' | base64)\"\n```\n\nReference the secret in your Helm values:\n\n```yaml\nsecretEnv:\n  name: registry-ui-secret\n```\n\nFor all available configuration options, see [`charts/docker-registry-ui/values.yaml`](./charts/docker-registry-ui/values.yaml).\n\n---\n\n## Authentication\n\nFor registries with authentication, you must add the auth environment variable as a base64 encoded value of `username:password`\n\n```bash\necho -n \"username:password\" | base64\n# dXNlcm5hbWU6cGFzc3dvcmQ=\n```\n\nAfterwards, use this value through the following environment variables:\n\n```bash\nREGISTRY_URL=https://registry.test\nREGISTRY_AUTH=dXNlcm5hbWU6cGFzc3dvcmQ=\n```\n\n---\n\n## Multiple Registry Support\n\nThe UI supports connections to multiple registries. Configure them via environment variables with suffixes:\n\n```env\n# Default registry\nREGISTRY_URL=https://repository.a.com\nREGISTRY_AUTH=...\n\n# Additional registries\nREGISTRY_URL_PERSONAL=https://repository.b.com\nREGISTRY_AUTH_PERSONAL=...\n\nREGISTRY_URL_BUSINESS=https://repository.business.com\nREGISTRY_AUTH_BUSINESS=...\n\nREGISTRY_URL_CUSTOM=https://repository.whatever.com\nREGISTRY_AUTH_CUSTOM=...\n```\n\nNotes:\n\n* From `v0.3.2`, `REGISTRY_AUTH` (or its suffixed variants) can be omitted for unauthenticated registries.\n* From `v0.5.0`, GitHub Container Registry is supported:\n\n  ```env\n  REGISTRY_URL_GHCR=https://ghcr.io\n  REGISTRY_AUTH_GHCR=base64(github-username:PAT)\n  ```\n\n  The PAT requires `delete:packages, repo, write:packages` permissions. [Generate a PAT](https://github.com/settings/tokens).\n\n---\n\n## Development\n\nTo contribute, set up a local development environment:\n\n```sh\n# Prepare environment variables\ncp .env.example .env\n# Example: echo -n \"USERNAME:PASSWORD\" | base64 \u003e .env\n\nbun install\nbun run dev         # start local dev server\nbun run lint        # run linter\nbun run lint:fix    # auto-fix linting issues where possible\n```\n\nPull requests are welcome. Please ensure code is linted and tested before submission.\n\n---\n\n## Storage Reclamation\n\nWhen deleting images, Docker Registry **v2/v3** only marks them as deleted. Disk space is not automatically reclaimed.\n\nUse the [Docker Registry Cleaner](https://github.com/eznix86/docker-registry-cleaner) for automated cleanup, or run garbage collection manually:\n\n```sh\n# Run garbage collection\nbin/registry garbage-collect --delete-untagged /etc/docker/registry/config.yml\n\n# Optionally, remove an entire repository manually\nrm -rf /var/lib/registry/docker/registry/v2/repositories/\u003crepository_name\u003e\n```\n\nFurther reading:\n\n* [Docker Distribution: Garbage Collection](https://distribution.github.io/distribution/about/garbage-collection/)\n* [Cleaning Up Registry Blobs in Kubernetes](https://thelinuxnotes.com/how-to-cleanup-container-registry-blobs-in-kubernetes-with-garbage-collection/)\n* [DigitalOcean: Clean Up Container Registry](https://docs.digitalocean.com/products/container-registry/how-to/clean-up-container-registry/)\n* [Community Guide: Reclaiming Disk Space](https://dev.to/limal/reclaiming-free-disk-space-from-a-private-docker-repository-30f5)\n* [GitHub Issue: Registry Garbage Collection](https://github.com/distribution/distribution/issues/3178)\n\n---\n\n## How to Contribute\n\nContributions are welcome.
