Hands-on Tutorials
Zero to Hero39☸🐳🔷🔥📊🐙⚙️🔄⎈🔀🐧🏗️💻🟡🔐🟩🐍🐹🦀🔎🏠📡⚡🛡️⚖️🌪️🔭🧹🧠🌬️🤖🎯🎭🔐🔎🛡️🔬🔑🐷
Kubernetes: Getting Started
Install, spin up a local cluster, deploy, expose, scale, roll out, and debug — all hands-on.
Docker: Zero to Hero
From your first container to lean, secure multi-stage images and multi-service Compose stacks.
Terraform: Zero to Hero
Declare infrastructure, master state, build reusable modules, and collaborate with remote state.
Prometheus: Zero to Hero
Scrape metrics, write PromQL, record rules, alert with Alertmanager, and harden for production.
Grafana: Zero to Hero
Wire up data sources, build panels, template with variables, alert, and manage dashboards as code.
Argo CD: Zero to Hero
GitOps for Kubernetes — deploy from Git, auto-heal drift, roll back, and scale to many apps.
Ansible: Zero to Hero
Agentless automation — idempotent playbooks, templates, secrets with Vault, and reusable roles.
GitHub Actions: Zero to Hero
Build CI/CD with events, jobs, matrices, caching, secrets, environments, and secure deploys.
Helm: Zero to Hero
Package Kubernetes apps — install charts, template your own, manage values, and roll back safely.
Git: Zero to Hero
Master the three trees, branch and merge, rebase vs merge, undo anything safely, and a PR workflow that scales.
Linux: Zero to Hero
Filesystem, permissions, processes and signals, the text-processing toolkit, systemd, and troubleshooting reflexes.
Jenkins: Zero to Hero
Pipeline-as-code with stages, triggers, credentials, parallel matrices, agents, and shared libraries.
Bash: Zero to Hero
Write safe, reusable scripts — quoting, exit codes, loops, functions, strict mode, and shellcheck habits.
AWS: Zero to Hero
The mental model that matters — IAM, VPC networking, compute, S3, cost guardrails, and a security baseline.
Vault: Zero to Hero
Centralize secrets — KV, least-privilege policies, auth methods, dynamic credentials, and Transit encryption.
Nginx: Zero to Hero
Serve static files, reverse-proxy apps, terminate TLS, load-balance, cache, rate-limit, and harden.
Python for DevOps: Zero to Hero
Environments, the scripting toolkit, calling cloud/K8s APIs, testing, and packaging installable CLIs.
Go: Zero to Hero
The cloud-native language — types, errors, goroutines, an HTTP service, and tiny static container images.
Rust: Zero to Hero
Memory safety without a GC — ownership, enums/match, Result, traits, fearless concurrency, static binaries.
OpenSearch: Zero to Hero
Index documents, write queries and aggregations, map fields, ingest logs, and scale with shards.
ClickHouse: Zero to Hero
Columnar analytics at scale — MergeTree and sort keys, batch loads, materialized views, partitioning, and TTL.
tcpdump: Zero to Hero
Capture packets, read TCP flags, write BPF filters, save to pcap, and debug which side of the wire is broken.
KEDA: Zero to Hero
Event-driven autoscaling — scale on queues, Kafka lag, PromQL, or cron, all the way to zero, with ScaledObjects/Jobs.
Kyverno: Zero to Hero
Kubernetes policy-as-code in YAML — validate, mutate, generate, verify images, and roll out audit-then-enforce.
Open Policy Agent: Zero to Hero
General-purpose policy with Rego — evaluate decisions, guard Kubernetes via Gatekeeper, and test configs with conftest.
Chaos Mesh: Zero to Hero
Chaos engineering on Kubernetes — inject pod, network, and stress faults with a hypothesis and a small blast radius.
OpenTelemetry: Zero to Hero
Vendor-neutral traces, metrics, and logs — instrument once, run the Collector, propagate context, and sample smartly.
Cloud Custodian: Zero to Hero
Cloud governance as YAML — find and remediate untagged, public, idle, or unencrypted resources with filters and actions.
Kubeflow: Zero to Hero
ML on Kubernetes — pipelines, distributed training operators, Katib tuning, and KServe serving for reproducible MLOps.
Apache Airflow: Zero to Hero
Orchestrate data pipelines as code — DAGs, the TaskFlow API, operators/connections, idempotent runs, and executors.
Kubernetes Operators: Zero to Hero
Extend Kubernetes — CRDs plus a controller and the reconcile loop, level-triggered and idempotent, with Kubebuilder.
k6: Zero to Hero
Load testing as code — virtual users, checks, SLO thresholds that gate CI, realistic load profiles, and custom metrics.
Playwright: Zero to Hero
Reliable end-to-end browser testing — resilient locators, auto-waiting, auth reuse, network mocking, and the trace viewer.
DevSecOps: Zero to Hero
Security in every stage — shift left, SAST/DAST/SCA, secrets and policy-as-code, a fail-fast pipeline, and the metrics that prove it works.
Semgrep: Zero to Hero
Fast SAST with code patterns, not regex — run scans, write custom rules and taint mode, autofix, and gate CI on the diff.
Trivy: Zero to Hero
One scanner for images, filesystems, IaC misconfig, secrets, and SBOMs — filter to fixable CVEs and gate CI on severity.
Grype: Zero to Hero
SBOM-first vulnerability scanning with Syft — scan images and SBOMs, filter fixable findings, and fail the build on Critical.
GitLeaks: Zero to Hero
Stop secrets before they leave your laptop — pre-commit hooks, history scans, custom rules, baselines, and the leak response.
TruffleHog: Zero to Hero
Secret scanning that verifies whether a key is live — scan Git, S3, and images, and gate CI only on confirmed-working credentials.
