debugger

A container image with tools and utilities for debugging services in the k8s world

Build and publish

All the necessary files for building the container image are in the image directory.

• The Dockerfile describes which tools are installed in the image;
• The convenience script build.sh builds the container and publish it.

Usage

The debugger container is described via 2 YAML files:

• k8s/deployment.yaml, to deploy the container on one node only;
• k8s/daemonset.yaml, to deploy the container on all the nodes of the cluster.

If the provided defaults are satisfactory, the container can be deployed with:

kubectl apply -f https://raw.githubusercontent.com/sciencebox/debugger/master/k8s/deployment.yaml

In case some changes must be applied to the configuration before deploying, please clone this repository and edit the YAML files:

git clone https://github.com/sciencebox/debugger.git
# Apply your changes to k8s/deployment.yaml
kubectl apply -f k8s/deployment.yaml

Defaults

The debugger container:

• Runs in privileged mode and privilege escalation is allowed;
• Uses the host PID space and IPC;
• Uses the hostNetwork;
• Mounts / of the host at /host_root.
