Docker Image Workflows

Build and Publish

Features:

• Multi-platform builds (linux/amd64, linux/arm64 by default)
• Automatic repository naming based on group name
• OIDC authentication with JFrog
• Flexible build configuration (context, dockerfile path, build args, secrets)
• Build attestation support
• Custom additional tags

JFrog Artifactory

The workflow for building and publishing Docker images to JFrog Artifactory.

Implementation: .github/workflows/docker-build-push-jfrog.yaml

Simple Example: examples/docker/build-push-jfrog-simple.yml Complete Example: examples/docker/build-push-jfrog-complete.yml

Docker Hub

The workflow for building and publishing Docker images to Docker Hub.

Implementation: .github/workflows/docker-build-push-dockerhub.yaml

Simple Example: examples/docker/build-push-dockerhub-simple.yml Complete Example: examples/docker/build-push-dockerhub-complete.yml

Promote

The workflow for promoting Docker images between environments (dev → staging → prod).

Features:

• Promotes images between environments
• Maintains build provenance attestation
• Supports multiple tags promotion
• Detailed promotion summary

JFrog Artifactory

Implementation: .github/workflows/docker-promote-jfrog.yaml

Example: examples/docker/promote-jfrog.yml

Docker Hub

Implementation: .github/workflows/docker-promote-dockerhub.yaml Example: examples/docker/promote-dockerhub.yml

Environment Flow - JFrog Artifactory

Docker images follow this promotion path:

dev (build) → staging (promotion) → prod (promotion)

Each environment has its own Artifactory repository:

• {group}-oci-local-dev
• {group}-oci-local-staging
• {group}-oci-local-prod

Environment Flow - Docker Hub

Docker images follow this promotion path:

dev (build) → prod (promotion)

Each environment has its own Docker Hub repository:

• dev -> nethermindeth
• prod -> nethermind
