Don't let this gap widen

Why this program matters

  • Without this upskilling, your team accumulates a technological gap that translates directly into productivity loss.

  • Organizations that don't train their talents on key topics see their competitiveness drop.

  • Every quarter without training is a gap widening with competitors who invest.

  • The cost of inaction quickly exceeds that of well-targeted training.

Let's Encrypt training objectives

  • Master the implementation of Let's Encrypt certificates from zero to production
  • Configure Certbot and pre- and post-validation hooks on Debian and Ubuntu environments
  • Automate certificate renewal and monitoring with systemd timers and Prometheus
  • Secure web deployments by applying TLS 1.3 and HSTS best practices
  • Integrate certificate issuance into GitLab and GitHub Actions CI/CD pipelines
  • Diagnose common DNS and HTTP-01 challenge errors with debugging tools

Program

Let's Encrypt curriculum: 5 modules over 5 days

Module 1 : Principles and First Let's Encrypt Certificates (Certbot, ACME)

Presentation of the ACME protocol and how Let's Encrypt works. Installation of Certbot on a Debian server, obtaining the first certificate using the HTTP-01 method, verification of Apache and Nginx configuration files. Practical exercise: deploying a certificate on a test site and verification with SSL Labs.

Module 2 : Automating Let's Encrypt Renewal (systemd, hooks)

Setting up systemd timers for automatic renewal, creating pre- and post-deployment hooks, managing permissions and services to reload. Real-world case: configuring a production server with automatic certificate switching without service interruption.

Module 3 : Advanced Deployment and DNS-01 Let's Encrypt (acme.sh, Cloudflare)

Using acme.sh for environments without a web server, configuring the DNS-01 challenge via the Cloudflare API, token rotation and zone management. Exercise: obtaining a wildcard certificate and deploying it on multiple subdomains with DNS record updates.

Module 4 : Integrating Let's Encrypt in CI/CD and Containers (Docker, GitHub Actions)

Integrating certificate issuance into CI/CD pipelines, using Docker containers with persistent volumes, secrets and healthchecks. Use case: GitHub Actions pipeline deploying a containerized application with a valid Let's Encrypt certificate in production.

Module 5 : Monitoring, Auditing and Troubleshooting Let's Encrypt (Prometheus, Grafana)

Setting up expiration metrics with Prometheus and Grafana alerts, analyzing ACME error logs, resolving rate limiting issues. Final deliverable: monitoring dashboard and documented troubleshooting procedure for the operations team.

How Let's Encrypt skills are assessed

  • Knowledge validation quiz at the end of each day
  • Practical exercises on a test server with group debriefing
  • Evaluation grid for deliverables submitted at the end of the training

How the Let's Encrypt course is taught

  • Installation and configuration of Certbot and acme.sh
  • Automation of the certificate lifecycle
  • Integration into DevOps pipelines
  • Monitoring and troubleshooting of TLS deployments

Let's Encrypt training: access and practical arrangements

The Training Let's Encrypt: From Zero to Production program is delivered onsite or remote (blended-learning, virtual classroom, remote presence). At Learni, an industry-certified training organization, every program is built to maximize skills acquisition regardless of the chosen format.

Our method

How Learni guarantees the quality of your Let's Encrypt training

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.

Step 1

Rigorous trainer selection

Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.

  • Triple validation: technical, pedagogical, sectoral.
  • Minimum rating 4.8/5 over the last 12 sessions.
Step 2

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.
Step 3

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.
Step 4

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.
