Don't let this gap widen
Why this program matters
Without advanced Helm mastery, 70% of Kubernetes deployments fail in production, causing an average of 4h downtime per incident according to CNCF, with financial losses of 10k€/h for an e-commerce app.
Risk error-prone manual configs, poorly managed hooks blocking DB migrations, or upgrades crashing critical services?
Untrained teams waste 40% of time on Helm debugging, multiplying vulnerabilities (exposed CVEs).
Invest 35h to avoid these pitfalls: faulty charts = 25% avoidable breaches, poorly managed multi-env = project delays x3.
Master Helm or suffer the hidden costs.
Program
Module 1Advanced Charts: Structuring and Customization (Helm CLI, Go Templates).
Dive into creating sophisticated Helm charts, model modular structures with practical exercises on microservices apps, test via helm lint and template, produce your first reusable chart by handling dependencies and subcharts, gain autonomy to scale your Kubernetes deployments.
Module 2Dynamic Templating: Values, Helpers, and Conditions (Helm 3.x).
Explore the Go template engine for intelligent YAML rendering, practice values.yaml overrides on real e-commerce app cases, integrate helper functions and loops, generate environment-adaptive manifests, experience the power of Helm for flexible, error-free configs.
Module 3Hooks and Lifecycle: Migrations and Validations (Pre/Post Hooks).
Master Helm hooks to orchestrate DB migrations and validations, simulate blue-green deployments with exercises on real clusters, test pre-install/post-delete, create custom Kubernetes jobs, transform your releases into reliable, automated processes ready for critical production.
Module 4Multi-Environments: Helmfile and Umbrella Charts (GitOps).
Deploy to dev/staging/prod via Helmfile, configure multiple environments with value sets, practice umbrella charts for entire microservices, integrate ArgoCD for GitOps, produce reproducible pipelines, adopt a scalable approach that boosts your DevOps velocity.
Module 5Security, Troubleshooting, and Best Practices (Helm Security, Upgrades).
Secure your charts with Trivy scans and OPA policies, diagnose downtimes via helm history and debug, optimize rolling upgrades without interruption, review best practices on real leak cases, deliver a final secure chart, leave as an expert for zero production incidents.
Evaluation method
- Continuous assessment through practical exercises, final quizzes, and delivery of a complete chart project.
Learning method
- 70% hands-on practice on real clusters, 30% theory with business cases, personalized feedback.

Our method
Training quality, guaranteed at every step
Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.
You meet the trainer beforehand
30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.
- Live briefing on goals and team context.
- Veto right — we swap the trainer for free if needed.
Content tailored to your context
No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.
- Hands-on cases drawn from your stack and projects.
- Program co-written then validated by your team.
Continuous quality follow-up
Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.
- NPS, knowledge quizzes and skills self-assessment.
- Satisfaction guarantee: fully satisfied or free rework.
A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
