NixOS: Declarative Linux for Reproducible Sovereign Infrastructure Training Course

Gitea is a lightweight, open-source, self-hosted Git service offering repository management, code review, issue tracking, and CI/CD integration. It serves as an increasingly popular alternative to GitHub and GitLab.com for teams needing full control over their source code without third-party terms of service or export restrictions.

GitLab Self-Managed is the on-premises deployment of GitLab's complete DevSecOps platform, including source code management, CI/CD, container registry, security scanning, and monitoring. It is the gold standard for organizations that want the full GitLab feature set without SaaS dependency or data leaving their network.

This instructor-led, live training in Nigeria (online or onsite) is aimed at intermediate to advanced DevOps engineers and system administrators who wish to deploy and manage self-hosted Kubernetes clusters without cloud dependencies.

By the end of this training, participants will be able to: deploy production-ready Kubernetes clusters using kubeadm on bare-metal or virtual machines; configure high-availability control planes and etcd clusters; implement container networking and storage for self-managed environments; set up monitoring and observability using self-hosted solutions.

This instructor-led training, offered online or onsite, targets cloud professionals aiming to design and implement multi-cloud architectures that prevent vendor lock-in and guarantee data sovereignty.

By the end of the course, attendees will be capable of identifying vendor lock-in risks, designing portable architectures, implementing data sovereignty controls, and making effective use of cloud-agnostic tools.

This instructor-led, live training in Nigeria (online or onsite) is aimed at network engineers and infrastructure professionals who wish to use SONiC and ONL to deploy and manage open network infrastructure on white-box switches.

By the end of this training, participants will be able to: understand SONiC and ONL architecture, deploy open-source NOS on white-box hardware, configure networking features, and implement monitoring and automation.

This instructor-led, live training (available online or on-site) is tailored for system administrators and infrastructure engineers seeking to design, deploy, and manage private OpenStack cloud infrastructures for enterprise settings.

By the end of the course, participants will understand OpenStack architecture, deploy private cloud infrastructure, manage compute and storage resources, implement security via Keystone, and apply enterprise-grade best practices.

This instructor-led live training in Nigeria (online or onsite) is aimed at intermediate-level network engineers and infrastructure administrators who wish to implement software-defined networks using open source tools and technologies.

By the end of this training, participants will be able to design SDN architectures, implement Open vSwitch, configure FRRouting, deploy SDN controllers, and automate network management.

This instructor-led live training in Nigeria (online or onsite) is designed for intermediate-level network and infrastructure professionals who wish to use open-source routing, switching, Wi-Fi, and management tools to design, deploy, and operate a self-managed enterprise network.

By the end of this training, participants will be able to: design an open-source enterprise network architecture, configure routing, switching, and wireless services, enhance security and observability, and develop an operational plan for ongoing support.

Terraform is an open-source infrastructure-as-code tool that empowers teams to define and provision data center infrastructure using a declarative configuration language. When paired with self-hosted backends and on-premise providers, Terraform becomes a potent instrument for sovereign infrastructure management, effectively eliminating cloud vendor lock-in.

This instructor-led, live training (available online or onsite) is designed for intermediate infrastructure engineers seeking to leverage Terraform to manage self-hosted environments, including Proxmox, VMware, libvirt, and bare-metal provisioning.

By the end of this training, participants will be able to:

• Write robust Terraform configurations for on-premise and hybrid resources.
• Securely manage state using self-hosted backends such as PostgreSQL, S3-compatible storage, and Gitea.
• Utilize provisioners and custom providers to manage the entire bare-metal lifecycle.
• Implement efficient workspaces, modular architectures, and variable hierarchies.
• Integrate Terraform into CI/CD pipelines for automated infrastructure delivery.

Format of the Course

• Interactive lectures and guided discussions.
• Extensive exercises and practical labs.
• Hands-on implementation in a live-lab environment.

Uptime Kuma is an easy-to-use, self-hosted monitoring tool that tracks the availability of websites, services, and infrastructure. It replaces Pingdom, Datadog Synthetics, and UptimeRobot for teams that want monitoring data under their own control. This instructor-led, live training (online or onsite) is aimed at beginner-to-intermediate SREs and DevOps engineers who wish to use Uptime Kuma to replace cloud uptime monitoring with a self-hosted, sovereign status tracking platform.

This instructor-led, live training in Nigeria (online or onsite) is aimed at security engineers and system administrators who wish to deploy and manage enterprise-grade self-hosted VPN solutions using WireGuard and OpenVPN.

By the end of this training, participants will be able to deploy WireGuard and OpenVPN, design scalable architectures, integrate with identity systems, and monitor/secure VPN infrastructure.

OpenVPN and WireGuard are the two leading open-source VPN protocols. By hosting your own VPN server, you guarantee that no third-party provider can log traffic metadata, inject advertisements, or comply with foreign data requests. This training covers both protocols to address various threat models and performance requirements.

Wazuh is an open-source security platform delivering unified XDR and SIEM capabilities for threat detection, integrity monitoring, incident response, and compliance. It aggregates endpoint telemetry into a self-managed analysis engine, serving as a credible alternative to Splunk Enterprise Security, Microsoft Sentinel, and other cloud-native SIEMs.

Woodpecker CI is a straightforward yet robust continuous integration engine built specifically for self-hosted Git platforms like Gitea and Forgejo. It offers a lightweight, Docker-native CI/CD experience, sparing users the complexity and licensing costs typically associated with enterprise CI solutions.

This instructor-led, live training in Nigeria (online or onsite) is aimed at intermediate-level to advanced-level security professionals who wish to implement Zero Trust Architecture using open-source tools and sovereign infrastructure.

By the end of this training, participants will be able to design Zero Trust architectures, deploy identity-aware proxies, implement dynamic authentication, secure microservices with service mesh, and monitor zero trust policies.
