Network Troubleshooting and Debugging Tools Container

This Docker image is based on Alpine Linux and includes a comprehensive suite of network troubleshooting and debugging tools. Additionally, it hosts a small Go program that echoes back HTTP request information in JSON format, ideal for debugging and inspecting incoming requests.

Tools Included

• Common network utilities (ip, netstat, route, nmap, nc, socat, etc.)
• DNS utilities (dig, nslookup)
• Network monitoring tools (nethogs, iftop, mtr, traceroute, tcpdump)
• jq for JSON processing
• Custom Go program to echo HTTP requests

Running the Container

To run the container on port 8080, use the following command:

docker run -d --rm --name nshoot -p 8080:80 rbehzadan/nshoot

Using the Container

Once running, you can execute commands within the container to debug network issues.

$ docker exec -it nshoot sh

For example, to access the Go echo server:

$ curl -s localhost:8080 | jq
{
  "url": "/",
  "method": "GET",
  "query_params": {},
  "headers": {
    "Accept": [
