kubernetes-debug-image

Debug image for debugging within a kubernetes cluster.

Debug deployment

Example of yaml file containing the deployment of debugger pods.
Namespace needs to be changed to match the environment it's deployed in.
Currently the image is set to the default debug-image.
Consider adding egress rules for debugging the network.
Default duration before container terminates is 30 minutes.
This can be overwritten in the args field on the container.
The time must be set in seconds.
