⁠Docker Debugging Container

This is a super simple container that can be used for debugging directly inside Kubernetes.

⁠Container Tools

This container is running Ubuntu 22.04 with the following tools installed for use in an interactive shell:

1. Packages
   1. vim - For editing files in the container to adjust tests
   2. curl - For testing APIs
   3. wget - For downloading files
   4. dnsutils - For testing DNS
   5. telnet - For testing network connections
   6. apache2 - Webserver that the container runs via CMD
   7. libapache2-mod-php - PHP for Apache2
   8. iputils-ping - Adding the ping command for basic network tests
2. Services
   1. A simple PHP page on port 80 that will show the container IP and the headers sent to the web server.
3. Other Stuff
   1. A stripped down version of my usual bash profile.

⁠Architectures

This container is available for linux/amd64, and linux/arm64

⁠Deployment Examples

There are two deployment examples included with this repo:

1. docker-compose⁠ - Deploy locally and listen on port 2000
2. Kubernetes⁠ - Deploy to Kubernetes in the kube-public namespace listening on port 80 with no ingress or service

You can also run docker run -d --name debugging -p2000:80 ahrenstein/debugging:latest to deploy locally as well.

⁠Why?

Busybox was too simple for some of the debugging I needed to do. I wanted a container that I can test host headers with, but also have an interactive shell with some common packages and the ability to install more via apt-get should I need them.

⁠Availability

All linux/amd64 versions up to 5.0.0 are publicly available on Docker Hub⁠
All linux/amd64 and linux/arm64 versions from 5.0.1 onward are publicly available on Docker Hub⁠ and GitHub Container Registry⁠
