As security threats intensify and compliance rules grow stricter, development teams are looking for more than just tools, they want trusted partners to ensure their software supply chains are protected. Recognizing this need, Docker is expanding its Docker Hardened Images (DHI) Catalog to include Helm charts, making secure Kubernetes deployments more accessible and manageable.
The Role of Helm Charts in Modern Deployments
Helm charts have become essential for packaging and deploying applications on Kubernetes, with roughly 75% of users relying on them according to CNCF surveys. However, using unverified or outdated charts can create new vulnerabilities. Docker addresses this risk by building security and traceability directly into the deployment process, setting a new standard for Kubernetes workflows.
- Streamlined Security: Every chart in the DHI Catalog is pre-configured to use Docker Hardened Images, eliminating the worry of insecure sources or dependencies.
- Traceability and Trust: Charts are built with Docker's hardened SLSA Level 3 build system, offering signed provenance for every deployment.
- Continuous Updates: Automated updates ensure charts stay current with upstream releases and critical security patches, reducing manual maintenance.
Navigating Industry Changes: The Bitnami Shift
Recent changes to Bitnami’s distribution model by Broadcom have left many teams searching for alternatives, as most images and charts now require commercial subscriptions and older versions lack updates. Docker provides two distinct paths forward:
- Docker Official Images (DOI): Free, stable images that pair with upstream Helm charts for open source needs.
- Docker Hardened Images with Helm Charts: Enterprise-grade security and compliance, now available through the DHI Catalog for organizations with advanced requirements.
This ensures teams can continue open source operations or migrate to a more robust, compliance-ready platform without unnecessary disruption.
DHI Helm Charts Beta: What to Expect
The Docker Hardened Images Helm charts are in beta, giving early adopters a unique opportunity to shape their evolution. Key features include:
- DHI by Default: All charts reference Docker Hardened Images, guaranteeing deployments benefit from enhanced security and compliance.
- Customer-Driven Development: Beta feedback will determine which charts are prioritized and how features are developed.
- Enterprise Security: Charts are built to advanced security standards with signed provenance and compliance documentation.
- Automated Updates: Regular patches and upstream syncs keep deployments secure with minimal team effort.
Participating in the beta allows organizations to migrate seamlessly and ensure end-to-end security from development to production.
Docker’s Image Catalogs: Flexibility and Assurance
Docker offers both free community-maintained images and enterprise-grade hardened solutions. Docker Official Images remain stable and accessible, while Docker Hardened Images deliver compliance, minimal vulnerabilities, and SLA-backed updates—now further enhanced by secure Helm chart integration for modern Kubernetes environments.
Shape the Future of Secure Cloud-Native Deployments
By adding Helm charts to the DHI Catalog, Docker demonstrates a strong commitment to security, simplicity, and customer collaboration. Teams navigating industry changes or seeking to improve their Kubernetes security posture can join the invite-only beta and influence these vital tools. The outcome is clear: secure, compliant, and streamlined Kubernetes deployments, all supported by Docker’s trusted ecosystem.
