Interactive Playground Labs
Docker Sandbox
Run containers, map host ports, mount volumes, inspect logs, and build Dockerfiles in an in-memory client engine.
Kubernetes Cluster
Practice kubectl imperatives, deployments, cluster services, replica scaling, and CKA multi-node drain tasks.
Terraform IaC Sandbox
Parse HCL files, run terraform init, validate, calculate execution plans, and apply simulated AWS VPC & EC2 state.
Core DevOps Tracks
Docker & Containerization
Master container virtualization, Dockerfiles, multi-stage builds, Docker Compose, volumes, networking, and security best practices.
Kubernetes & Cloud Orchestration
Orchestrate microservices with Pods, Deployments, Services, Ingress, ConfigMaps, Secrets, PVCs, and automated rollouts.
Terraform (Infrastructure as Code)
Provision multi-cloud infrastructure declaratively. Master HCL, state locks, reusable modules, workspaces, and CI/CD pipelines.
AWS Cloud Engineering
Deploy highly available systems on Amazon Web Services. Covers VPC, EC2, S3, IAM, ALB, ECS, EKS, RDS, and CloudWatch.
CI/CD & DevOps Automation (GitLab)
Automate build, test, lint, security scans, container publishing, and automated canary deployments with GitLab CI/CD.
GitHub Actions Workflows
Write automated workflows with triggers, matrix builds, secrets, reusable composite actions, and OIDC AWS authentication.
Git & Version Control
Branching strategies, interactive rebasing, merge conflict resolution, git hooks, cherry-pick, and GitOps workflows.
Linux & Shell Scripting
The backbone of DevOps. Master bash commands, pipes, permissions, process management, systemd, networking, and log analysis.
DevOps Tools & Linters
Regex Tester & Pattern Builder
Live regex tester with capture group inspector, replacement preview, token cheatsheet, and code generators in JS, Python, Go, Java, and PHP.
Python Regex Tester (re module)
Test Python re patterns with named groups (?P<name>), backreferences, flags (re.I, re.M, re.S), and instant re.compile snippets.
Java Regex Tester (Pattern & Matcher)
Test java.util.regex patterns with named groups, auto-escaped backslashes for Java strings, and matcher.replaceAll previews.
Cron Expression Parser
Translate standard 5-part cron syntax into plain English and calculate the next execution timestamps.
