kube-tools - Container Stress Test and Scanning

---

Project Overview

This project is a collection of Golang tools for container port scanning, container memory stress testing, and container CPU stress testing. These tools can help you perform performance testing and resource utilization evaluation on containers.

Functionality

1. Container Port Scanner

This tool is used to scan the open ports inside a container to ensure the container's network configuration is correct and the ports are accessible.

Usage

kube-tools scan -H baidu.com -T tcp -P 80,443

• -H, --host string host to scan (default "localhost")
• -P, --ports string ports to scan (default "22")
• -T, --protocol string protocol to scan (default "tcp")

2. simulate memory usage.

This tool is used to simulate memory usage to test the container's memory resource utilization.

Usage

kube-tools memory -P 8888 -S 10240

• -P, --port string Port to listen on (default "8080")
• -S, --size int Memory size in MB

3. metrics

Usage

kube-tools metric -P 8080

• -P, --port string ports to scan (default "8080")

4. traceroute

Usage

kube-tools traceroute --host localhost

• -H, --host string host to scan (default "localhost")

5. cpu simulate cpu load

Usage

kube-tools cpu --cores 5 --minutes 1

• -C, --cores int the number of cores to use. (default 1)
• -M, --minutes int the minute time to run the simulation. (default 1)

6. generate jwt token

Usage

kube-tools token --issuer kubernetes --username osadmin --password password --port 8888 --expire 5200

{
    "access_token": {
        "access_token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VybmFtZSI6ImFkbWluIiwicGFzc3dvcmQiOiJwYXNzd29yZCIsImV4cCI6MTY5MTg1ODczMywiaXNzIjoiaXNzdWVyIn0.KBEOkIAYuuGiLoJyqrZnkyRs9OdvOL8qrtnu_eWWR2k",
        "expire_time": 1691858733
    },
    "refresh_token": {
        "expire_time": 1694443533,
        "refresh_token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VybmFtZSI6ImFkbWluIiwiZXhwIjoxNjk0NDQzNTMzLCJpc3MiOiJpc3N1ZXIifQ.8KItuXDDnSef5FBiUe1pBeSOJoC2S0Iv88a51Yiy5TM"
    }
}

• -E, --expire duration The token expire time, default 7200s. (default 7.2µs)
• -I, --issuer string The issuer of the token. (default "issuer")
• -W, --password string The password of the token. (default "password")
• -P, --port string The http web service listening port. (default "8080")
• -U, --username string The username of the token. (default "admin")
