Master the command line, file systems, process management, and Bash scripting — the bedrock every DevOps engineer must own.
Beginner
1–2 wks
03
Branching strategies, merge conflicts, pull request workflows, Git hooks, and monorepo management.
Intermediate
3–5 wks
04
Images, multi-stage builds, Compose, networking, volumes, registries, and container security for production workloads.
Intermediate
4 wks
05
Design and optimise deployment pipelines — Jenkins, GitHub Actions, GitLab CI, ArgoCD, and release strategies.
Advanced
6–8 wks
06
Pods, deployments, services, Helm charts, RBAC, network policies, autoscaling, multi-cluster federation, and cost optimisation.
Intermediate
