DevOps Engineers ⚙️ Quick cheat sheet: Essential network ports you deal with daily!
Whether you're troubleshooting firewalls, configuring security groups, setting up Kubernetes clusters, or hardening Docker hosts, knowing these ports saves hours of debugging.
Must-know list:
- HTTP → 80
- HTTPS → 443
- SSH → 22
- FTP → 21
- MySQL → 3306
- Kubernetes API Server → 6443
- Docker Daemon API → 2375 / 2376 (TLS)
- MongoDB → 27017
- NGINX (default) → 80 / 443
- Grafana → 3000
- Prometheus → 9090
- Tomcat → 8080
- Apache Kafka → 9092
- Redis → 6379
- RDP (Remote Desktop) → 3389
- Elasticsearch → 9200
- Jenkins → 8080
- SMTP → 25
Pro tip: Always expose only what’s necessary and never leave the Docker API (2375/2376) open to the internet without strong auth/TLS! 🔒
