DevOps Toolchain Overview
The DevOps toolchain is the set of tools used across the 8 lifecycle phases. A senior DevOps engineer selects and integrates the right tools for each phase. This module gives you the full map of the DevOps toolchain.
The DevOps Toolchain Map
- CI/CD: GitHub Actions (preferred), GitLab CI, Jenkins, CircleCI, ArgoCD
- Containers: Docker, Podman
- Orchestration: Kubernetes, AWS ECS
- IaC: Terraform, AWS CloudFormation, Pulumi
- Config Management: Ansible, Chef, Puppet
- Monitoring: Prometheus, Grafana, Datadog, New Relic
- Logging: ELK Stack (Elasticsearch, Logstash, Kibana), Loki
- Secrets: HashiCorp Vault, AWS Secrets Manager
- Artifact Registry: Docker Hub, GHCR, AWS ECR, Nexus
- Source Control: GitHub, GitLab, Bitbucket
A Production DevOps Toolchain
// Modern production DevOps toolchain (2026 edition)
const productionToolchain = {
sourceControl: {
tool: "GitHub",
usage: "All code, IaC, and configuration stored here",
workflow: "Feature branches → PR → code review → main",
},
ciCd: {
tool: "GitHub Actions",
usage: "Build, test, and deploy on every PR and merge to main",
stages: ["lint", "test", "build", "scan", "deploy"],
},
containers: {
tool: "Docker + GHCR",
usage: "Package app into container image, push to registry",
bestPractice: "Multi-stage builds, minimal base images",
},
orchestration: {
tool: "Kubernetes + Helm",
usage: "Run containers at scale, manage deployments",
platform: "AWS EKS / GKE / AKS",
},
iac: {
tool: "Terraform",
usage: "Provision all cloud infrastructure as code",
state: "Remote state in S3 + DynamoDB lock",
},
monitoring: {
tool: "Prometheus + Grafana",
usage: "Metrics collection, dashboards, alerting",
slo: "99.9% uptime SLO tracked in real-time",
},
secrets: {
tool: "HashiCorp Vault",
usage: "Store and inject secrets dynamically",
principle: "No secrets in code or environment files",
},
};

Tip
Tip
Practice DevOps Toolchain Overview in small, isolated examples before integrating into larger projects. Breaking concepts into small experiments builds genuine understanding faster than reading alone.
Automate everything. GitOps for declarative deploys. Observe with metrics + logs + traces.
Practice Task
Note
Practice Task - (1) Write a working example of DevOps Toolchain Overview from scratch without looking at notes. (2) Modify it to handle an edge case (empty input, null value, or error state). (3) Share your solution in the Priygop community for feedback.
Common Mistake
Warning
A common mistake with DevOps Toolchain Overview is skipping edge case testing - empty inputs, null values, and unexpected data types. Always validate boundary conditions to write robust, production-ready devops code.
