okport

okport is a super lightweight HTTP server written in Go that listens on multiple ports and responds with 200 OK to all incoming requests.
It is designed specifically for infrastructure validation during the initial phase of container orchestration systems like Kubernetes, Nomad, or Docker Swarm.

---

✨ Features

• ✅ Listens on multiple ports simultaneously
• ✅ Always returns 200 OK regardless of path or method
• ✅ Zero configuration, no external dependencies
• ✅ Secure by design — minimal and transparent functionality
• ✅ Ideal for load balancer health checks and orchestration readiness probes

---

🚀 Usage

Run with Go

go run main.go 8080 9090 10080

Build and Run

go build -o okport main.go
./okport 8080 9090 10080

Docker

docker build -t okport .
docker run -p 8080:8080 -p 9090:9090 -p 10080:10080 okport 8080 9090 10080

🔧 Use Cases

• Initial deployment of container orchestrators (Kubernetes, Nomad, etc.)
• Multi-port health checks for L4/L7 load balancers
• Connectivity validation for firewalls, security groups, or ingress controllers
• Dummy service endpoints for DNS round-robin or service mesh testing

---

🔒 Security

This project follows the principle of least privilege:

• No input is reflected in the response — safe from XSS and injection
• No authentication, state, or cookies
• Only responds with 200 OK and a plain text body (OK\n)
• Not recommended for public exposure without reverse proxy or TLS termination
• Suitable for internal networking and automation environments

---

🛠 Build Requirements

• Go 1.18 or later
• No third-party libraries
