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
