Containers & Orchestration Skill

Overview

Master Docker and Kubernetes for production deployments.

Parameters

Name	Type	Required	Default	Description
platform	string	No	both	docker/kubernetes
operation	string	Yes	-	Operation type

Core Topics

MANDATORY

• Docker fundamentals (images, containers, volumes)
• Dockerfile best practices (multi-stage, security)
• Docker Compose
• Kubernetes architecture
• Deployments, Services, Ingress
• Health checks

OPTIONAL

• Helm charts
• ConfigMaps and Secrets

Quick Reference

# Docker
docker build -t app:v1 .
docker run -d -p 8080:80 --name app app:v1
docker logs -f container
docker exec -it container sh
docker system prune -af

# Docker Compose
docker compose up -d
docker compose logs -f
docker compose down -v

# Kubernetes
kubectl get pods -A
kubectl describe pod pod-name
kubectl logs -f pod-name
kubectl exec -it pod-name -- sh
kubectl apply -f manifest.yaml
kubectl rollout status deployment/app
kubectl rollout undo deployment/app

# Debugging
kubectl get events --sort-by='.lastTimestamp'
kubectl top pods
kubectl run debug --rm -it --image=busybox -- sh

# Helm
helm install release chart
helm upgrade release chart
helm rollback release 1

Troubleshooting

Common Failures

Symptom	Root Cause	Solution
ImagePullBackOff	Image not found	Verify name, check creds
CrashLoopBackOff	Container crashing	Check logs, verify CMD
Pending	Cannot schedule	Check resources, selectors
OOMKilled	Out of memory	Increase limits

Debug Checklist

1. Pod status: kubectl get pods -o wide
2. Events: kubectl describe pod
3. Logs: kubectl logs pod --previous
4. Resources: kubectl top pods

Recovery Procedures

CrashLoopBackOff

1. Get logs: kubectl logs pod --previous
2. Check events: kubectl describe pod
3. Test locally: docker run -it image sh
