Master Production
Troubleshooting
Real outage transcripts rebuilt as timed, graded drills. You get a live diagnostic shell, a countdown against the SLA, and a coach that explains why the wrong command was wrong — not a video of someone else fixing it.
Guided Paths
All 12 tracks →Role-shaped journeys that stack the modules in the order they actually build on each other.
DevOps Foundations
Shell, Linux internals, Git and containers — the ground floor everything else stands on.

Individual Skills
136 lessons · 43h totalShell Scripting
Master bash scripting, command-line pipelines, input validation, positional arguments, looping, file parsing, and defensive programming for automation.
Linux Systems
Understand kernel diagnostics, process states, signals, memory hierarchy, system call tracing, networking diagnostics, and storage optimization.
Git & Version Control
Learn branching strategies, cherry-picking, interactive rebasing, merge conflict resolution, hook automation, and production code promotions.
Docker & Containers
Build optimized multi-stage Dockerfiles, inspect network modes, bind mounts vs volumes, security hardening, and troubleshooting container exits.
Kubernetes
From the reconciliation loop to production operations: workloads, scheduling, the pod network, RBAC, autoscaling, upgrades and etcd — pinned to Kubernetes 1.36.
Helm
Package cloud-native applications with Helm charts, values overlays, templating functions, dependency management, and safe rollout releases.
Ansible
Automate configuration management, structure playbooks, leverage inventory variables, configure Ansible Vault secrets, and design idempotent roles.
Terraform
Write Infrastructure as Code, manage state locks, refactor modules, write dynamic blocks, import legacy resources, and manage cloud drift.
Jenkins & CI/CD
Construct robust declarative pipelines, manage shared libraries, authenticate secrets, hook webhooks, and deploy safe canary rollouts.
AWS Operations
Configure EKS nodepools, set up IAM roles for service accounts, structure security groups, provision ASGs, and optimize load balancers.
GCP Operations
Navigate GKE setups, configure Cloud Logging, inspect GCS lifecycle buckets, configure Service Accounts, and execute asset inventories.
Cloud Cost Optimization
Optimize EKS node allocation with Karpenter and CastAI, right-size compute, manage storage costs, clean unused elastic IPs, and configure savings plans.
