Overview
Process of tagging and publishing Docker images to a container registry for deployment across environments.
Description
After building and verifying a custom container, it must be tagged with a meaningful version identifier and pushed to a container registry (Docker Hub, NGC, ECR, GCR, ACR, or private) for distribution. This enables reproducible deployments across development, staging, and production environments.
Container distribution is the final step in the Custom Container Build workflow. It transforms a locally built image into a remotely accessible artifact that can be pulled by deployment systems, orchestrators (Kubernetes, ECS, Docker Compose), and other team members.
Key aspects of container distribution:
- Tagging strategy: Images should be tagged with identifiers that encode the Triton version, included backends, build date, or git commit hash. This enables precise identification of what is inside each image.
- Registry selection: The choice of registry depends on the deployment environment. Cloud-managed registries (ECR for AWS, GCR/Artifact Registry for GCP, ACR for Azure) provide tight integration with their respective orchestration services. Docker Hub and private registries serve multi-cloud or on-premises deployments.
- Access control: Registry authentication and authorization must be configured to ensure only authorized systems can pull production images.
- Image lifecycle: Old images should be retained for rollback capability but eventually cleaned up to manage storage costs.
Usage
Container distribution is performed after successful verification and before deployment. It is the final workflow step that makes the custom build available for use.
Typical scenarios:
- CI/CD pipeline publishing: Automated builds push tagged images to a registry after passing verification
- Team distribution: A custom build is pushed to a shared registry for use by multiple team members
- Multi-environment deployment: The same verified image is pushed once and pulled into dev, staging, and production environments
- Versioned releases: Production-ready images are tagged with semantic version identifiers for formal release management
Theoretical Basis
The principle follows an immutable artifact publication pattern:
- Tag with version -- Apply a meaningful, unique tag that identifies the image contents and provenance
- Push to registry -- Upload the tagged image to a container registry for centralized storage
- Pull for deployment -- Deployment systems pull the exact tagged image, ensuring consistency
This pattern provides critical properties:
| Property | Description |
|---|---|
| Immutability | Once pushed, a tagged image does not change. Any modification requires a new tag. |
| Reproducibility | Pulling the same tag always yields the same image, ensuring consistent deployments. |
| Rollback capability | Previous tags remain available, enabling instant rollback to a known-good version. |
| Auditability | The tag history in the registry provides a record of all published versions. |
| Distribution | Any authorized system anywhere can pull the image, enabling multi-region and multi-environment deployment. |
The tagging convention should encode enough information to identify the image contents without needing to inspect the image layers. Common patterns include:
<triton-version>-<backends>-<gpu|cpu>(e.g.,24.12-trt-py-gpu)<triton-version>-<date>-<git-short-hash>(e.g.,24.12-20260213-a1b2c3d)- Semantic version with metadata (e.g.,
v2.42.0-custom-slim)
