How the Toolchain Fits Together

A DevOps pipeline moves code from a developer's machine to production. Each stage has a category of tooling:

Code ──> Build ──> Test ──> Scan ──> Package ──> Deploy ──> Monitor
 │        │        │        │         │           │          │
 Git    CI      Test     Security  Container   K8s/IaC   Metrics/
        tools   runners  scanners  registry    Helm      logs/traces

Nobody learns every tool. Learn the categories, pick one tool per category, and go deep.

Version Control

Everything starts here. Version control tracks every change and enables collaboration.

Learn: clone, branch, commit, push, pull request, merge, rebase (later), .gitignore.

CI/CD Pipelines

CI (Continuous Integration) builds and tests every change. CD (Continuous Delivery/Deployment) ships it.

Key concept: pipelines-as-code — your build definition is a YAML file in the repo, reviewed like any code.

Containers and Orchestration

Learning path: Docker first → docker run, Dockerfile, Compose → then Kubernetes: Pods, Deployments, Services.

Infrastructure as Code

Provision infrastructure with code instead of clicking through consoles.

Terraform skills to learn first: init, plan, apply, state files, variables, modules.

Configuration Management

Configures what's inside machines — packages, files, services — after provisioning.

Ansible is the common starting point — agentless, readable YAML, ansible-playbook runs over SSH. Containers and immutable images have reduced the need for config management of long-lived servers, but Ansible remains valuable for bootstrapping and ad-hoc operations.

Monitoring and Observability

Three pillars: metrics, logs, traces.

Kubernetes standard: Prometheus scrapes metrics → Grafana visualises → Alertmanager pages. Start there.

Security Tooling

Security woven into the pipeline rather than bolted on after:

Minimum viable security: Gitleaks for secrets + Trivy for images + Dependabot for dependencies. Three tools cover the most common breach vectors.

Choosing Tools

Guidance for picking:

1. Start where your code lives — on GitHub? Actions is the path of least resistance. GitLab? Its built-in CI.
2. Managed beats self-hosted early on — Jenkins is powerful but you maintain it; GitHub Actions just runs.
3. Cloud alignment matters — Azure shop? Azure DevOps + AKS + Bicep/Terraform. AWS? CodePipeline or external CI + EKS + Terraform.
4. Learn concepts, not buttons — a pipeline is a pipeline; skills transfer between tools.
5. Avoid tool sprawl — every additional tool is something the team must maintain.

A Realistic Starter Stack

For a small team deploying containerised apps to Kubernetes:

That stack takes a small team from git push to a monitored production deployment — and every tool in it has a substantial free tier.
