Transition from Linux System Administrator to DevOps Engineer.

Transferable skills

  • Linux
  • Python / Go scripting
  • Security in pipelines

Skills to learn

  • CI/CD pipelines
  • Docker
  • Kubernetes
  • Terraform
  • Cloud (AWS/Azure/GCP)
  • Observability

Prerequisites

  • Solid Linux administration: package management, services, permissions, shell scripting.
  • Comfortable with networking fundamentals and a configuration management tool (Ansible is ideal).
  • Version control with Git — commits, branches and pull requests.
  • Exposure to at least one cloud provider’s console (AWS, Azure or GCP).

Step-by-step learning plan

  1. 1. Build on your Linux System Administrator experience

    2–4 weeks

    Leverage

    • Linux
    • Python / Go scripting
    • Security in pipelines

    Map transferable skills — Linux, Python / Go scripting, Security in pipelines — against what a DevOps Engineer needs.

  2. 2. Learn the core of the DevOps Engineer role

    6–10 weeks

    Learn

    • CI/CD pipelines
    • Docker
    • Git & branching strategies
    • Terraform

    Technologies

    KubernetesTerraformGitLab CI

    Cover the biggest gaps first: CI/CD pipelines, Docker, Git & branching strategies.

  3. 3. Master advanced DevOps Engineer skills

    6–10 weeks

    Learn

    • Kubernetes
    • Cloud (AWS/Azure/GCP)
    • Observability

    Technologies

    Handle the advanced topics: Kubernetes, Cloud (AWS/Azure/GCP), Observability.

  4. 4. Get productive with the DevOps Engineer toolchain

    4–8 weeks

    Technologies

    KubernetesTerraformGitLab CIGitHub ActionsJenkinsArgoCDHelmAWS

    Be hands-on with Kubernetes, Terraform, GitLab CI and the rest of the target stack.

  5. 5. Practise DevOps Engineer work in real conditions

    4–8 weeks

    Ship a portfolio project or take on DevOps Engineer tasks at work.

  6. 6. Get certified and position yourself as a DevOps Engineer

    4–8 weeks

    Update your CV and LinkedIn around DevOps Engineer, then apply to target roles.

Learning outcomes

  • Provision infrastructure reproducibly with Terraform and version it in Git.
  • Build and maintain a CI/CD pipeline that tests and deploys an application automatically.
  • Package and operate containerised workloads with Docker and basic Kubernetes.
  • Apply infrastructure as code and GitOps practices to a real workload.

Practical projects

  • Provision a server with Terraform — Replace a manual server build with a Terraform module that creates the VM, opens the right ports and tags it — then destroy and recreate it to prove it is reproducible.
  • Containerise a small app — Write a Dockerfile for a simple web app, build the image, run it locally and push it to a registry.
  • Wire a CI/CD pipeline — Connect a Git repository to a pipeline (GitHub Actions or GitLab CI) that runs tests and builds an image on every commit.
