Growing the Harness Developer Hub

Since announcing the general availability of the Harness Developer Hub, our writers have continued to publish new content and improve existing content. These updates, based on customer feedback, are aimed to enhance clarity, improve accuracy, and create a structure that better follows the user journey.

We want to take this opportunity to inform you about just some of these exciting changes.

Get Started with Tutorials

Our tutorials are a great place to get started with hands-on learning. We continue to add more tutorials and guides covering specific use cases for Harness modules. Recent additions include:

• Harness CI guides for various languages (C#, Go, Java, Node.js, Python, Ruby, and iOS/macOS) and publishing anything to the Artifacts tab.
• How to use CD to automatically deploy Kubernetes and GitOps services, AWS Lambda and Google Cloud Serverless functions, and traditional applications on cloud or physical data center VMs.
• How to integrate STO with GitLab and scan a Node.js app. 
• Feature Flag best practices and how to use Feature Flags in trunk-based development.
• How to manage secrets in the Harness Platform.
• How to configure self-managed external databases for Harness Self-Managed Enterprise Edition.
• CCM tutorials on AutoStopping and optimizing cloud costs for Kubernetes.

Learn more with Documentation

In addition to new documentation sets for Continuous Error Tracking and the Internal Developer Portal, we’ve improved and expanded content for our existing modules, the Harness Platform, and the Harness Self-Managed Enterprise Edition.

‍

Continuous Integration

The Harness CI documentation now has more introductory and summary information, such as the CI pipeline creation overview, to help you understand your CI pipelines at a high level. As you learn to use CI, the documentation moves from introductory to advanced configurations.

We’ve eliminated redundancy by combining reference topics with their “parent” sections or pages. This reduces the number of pages you need to visit to find the information you need. For example, the Upload Artifacts to GCS page includes helpful information about using this step in a CI pipeline as well as reference information for this step’s settings.

Almost all of the existing pages have been refreshed, and we’ve added several new topics. Here are some highlights:

• More migration guides.
• Addressed FAQs around code coverage and formatting test reports, with examples for different languages.
• Refreshed and expanded documentation on caching and artifacts management.
• A feature compatibility matrix comparing feature support across infrastructure types.
• Support for extensibility. You can create your own custom plugins, and you can use GHA, Bitrise, and Drone plugins in your pipelines.
• Check your license usage and manage your CI subscription directly in Harness.
• Troubleshoot with AIDA and debug with SSH.

Continuous Delivery & GitOps

The Continuous Delivery & GitOps documentation has been reorganized to provide a clearer path to onboarding and extending with Harness CD & GitOps. You can:

• Get started by creating your first CD pipeline (through YAML, API, the Harness Terraform Provider, or the Pipeline Studio’s visual editor), understanding modeling in Harness, learning about services and environments, and integrating CD with other Harness modules, such as CI.
• Upgrade CD from Harness FirstGen to Harness NextGen. The FirstGen and NextGen CD parity matrix lists the differences between Harness CD FirstGen (FG) and NextGen (NG) capabilities.
• Deploy services on different platforms and learn about cross-platform functionality.

Cloud Cost Management

The Harness CCM documentation has been reorganized into three main categories: cost reporting, cost optimization, and cost governance.

We’ve added more detail about what’s supported, and we’ve added several new topics about Asset Governance, including Asset Governance with AIDA and Asset Governance RBAC. Asset Governance is one of CCM’s key features, providing users with essential information on managing cloud assets using a Governance-as-Code approach that includes real-time enforcement and auto-remediation capabilities.

We’ve also added new topics about optimizing costs by applying recommendations for Azure VMs, using currency standardization for consistent cost analysis across CCM, and AutoStopping proxy load balancers.

Service Reliability Management

The Harness Service Reliability Management (SRM) documentation has undergone a comprehensive reorganization, designed to enhance the user's learning journey. The restructured documentation provides a clear roadmap for users to progress from foundational concepts to advanced topics. We’ve refreshed existing topics and added several new topics.

• Get started with SRM introduces SRM’s key features, including creating your first Service Level Objective (SLO). From there, explore and configure SLOs, monitored services, and notifications.
• Browse comprehensive catalogs of health sources and change sources supported by Harness SRM.
• The change impact analysis section explains how to use dashboards to correlate change events with service performance so you can make informed decisions and maintain service reliability.

Security Testing Orchestration

For STO, we’ve added definitions of key STO concepts like targets, baselines, variants, severity scores and levels, exemptions ("ignore rules"), and failing pipelines by severity.  

We’ve added several new workflows describing how to use GitHub Actions and Plugin steps to run scans, ingest SARIF data, use AIDA with STO, download scan images from private registries, add artifacts to STO pipelines, and stop pipelines automatically based on governance policies and scan results.

The scanner references have been revised and expanded, including scan steps that support scanner templates and information about scanner support by scan mode, binaries in STO container images, and Docker-in-Docker root access requirements.

Other highlights

In the Platform documentation, we’ve added information about AIDA and refreshed content about code repo connectors, getting started with Harness APIs, and access control.

For Feature Flags, we've added instructions for using Feature Flags with monitored services and Jira.

For Chaos Engineering, you can learn how to integrate CE with other Harness modules. We’ve also added information about managing chaos hubs, running a GameDay, and how we calculate resilience scores for experiments.

For the Harness Self-Managed Enterprise Edition, we’ve completely reorganized the documentation and added topics about what's supported, how to install in air-gapped environments, and how to manage Feature Flags. On the HDH, you can also find information about using CCM on the Harness Self-Managed Enterprise Edition.

Become a Harness-Certified Expert

The only constant in technology is change. Since the new series was first released in March of 2023, the Harness-Certified Expert Certifications have expanded. There are now more certifications available, and there are three levels of coverage for the Harness Continuous Delivery & GitOps module: Developer, Administrator, and Architect. The Administrator and Architect levels also include a hands-on portion to validate practical Harness skills.

You can sign up for a free Developer level certification or try one of the more advanced hands-on certifications today. Visit the HDH for all the latest developments across Harness. 

What’s Next?

As Harness continues to expand and evolve, so will our documentation. We have plans for more tutorials, more YAML examples, and other new and improved content. Check in on the HDH regularly for the latest updates.
