Container Orchestration Bundle

Four cheatsheets covering the full container lifecycle: building images with Docker, composing multi-service stacks locally, orchestrating them at cluster scale with Kubernetes, and packaging applications for repeatable deployment with Helm.

Each sheet is designed to be printed and pinned above your desk — the commands you actually use during incidents and deployments, not a re-printed man page.

What's Included

Docker Cheatsheet

Image lifecycle — build, tag, push, prune, multi-stage builds
Container operations — run, exec, logs, inspect, stats, stop vs kill
Volumes and bind mounts — when each is appropriate, backup strategies
Networks — bridge, host, overlay, and container-to-container DNS
Dockerfile patterns — layer ordering for cache efficiency, .dockerignore
Debugging — docker inspect JSON filtering, docker events, disk usage triage

Docker Compose Cheatsheet

Service definition syntax — the fields that matter in production
Environment handling — .env files, variable substitution, secrets
Health checks and depends_on conditions — real startup ordering
Override files — dev vs staging vs production from one base
Scaling and resource limits — deploy section, CPU/memory bounds
Common failure modes — orphan containers, stale networks, volume name clashes

Kubernetes Cheatsheet

Core objects — Pod, Deployment, Service, Ingress, ConfigMap, Secret
kubectl patterns — contexts, namespaces, -o jsonpath, label selectors
Rolling updates and rollbacks — kubectl rollout in practice
Debugging — describe, logs, exec, port-forward, ephemeral containers
Resource management — requests vs limits, QoS classes, node pressure
RBAC essentials — Role, RoleBinding, and service accounts

Helm Cheatsheet

Chart structure — Chart.yaml, values.yaml, templates
Template functions — pipelines, conditionals, ranges, named templates
Dependencies and subcharts — composing applications from reusable parts
Release management — install, upgrade, rollback, history
Values layering — set flags, values files, environment overrides
Hooks and tests — pre-upgrade jobs, chart verification

Excerpt — Docker Layer Caching

The difference between a 12-second and a 4-minute build is usually layer ordering. Copy your dependency manifests first, install dependencies, then copy source:

# Slow: any source change invalidates the dependency install
COPY . /app
RUN pip install -r /app/requirements.txt

# Fast: dependencies only reinstall when the manifest changes
COPY requirements.txt /app/
RUN pip install -r /app/requirements.txt
COPY . /app

Excerpt — Kubernetes Rollback

# Check rollout history
kubectl rollout history deployment/web -n production

# Roll back to the previous revision
kubectl rollout undo deployment/web -n production

# Pin a specific revision
kubectl rollout undo deployment/web --to-revision=3 -n production

# Watch rollout status until it settles
kubectl rollout status deployment/web -n production --timeout=120s

Choosing Between Docker Compose and Kubernetes

| Signal | Compose | Kubernetes | |---|---|---| | Single host, handful of services | ✔ | overkill | | Need self-healing and autoscaling | — | ✔ | | Team smaller than ~5 engineers | ✔ | consider later | | Multi-node or hybrid cloud | — | ✔ | | CI/CD with blue/green rollouts | possible | ✔ |

Many teams run Compose in staging and Kubernetes in production — the bundle covers both, so the same reference serves each environment.

Who This Is For

Developers and DevOps engineers running containerized workloads in staging or production
Teams adopting Kubernetes who need a quick reference for both Docker and K8s commands side by side
Anyone who wants printed cheatsheets on the wall instead of context-switching to browser tabs

FAQ

Do the sheets cover Podman or containerd? The Docker sheet targets the Docker CLI, but the majority of commands work identically under Podman's Docker-compatible interface. containerd users typically interact via Kubernetes or nerdctl — the K8s sheet covers that path.

Which Kubernetes version do the examples target? kubectl 1.29+ syntax. Where older clusters differ (notably kubectl run flags and ephemeral containers), the sheet notes the version boundary.

Are the cheatsheets updated? Yes — the bundle receives updates when major versions shift behaviour. Buyers get re-download access to new revisions through the library page.
