The presentation discusses the use of ephemeral containers for debugging running pods in Kubernetes clusters.
- Ephemeral containers allow for dynamic deployment of a container that shares pod resources
- They use Linux namespaces to share network and process resources for debugging
- Ephemeral containers provide privileged access to pods for complete debugging capabilities
- They also allow for running commands like ls and ps in containers for easier debugging
- Ephemeral containers can remain listed in the pod after exiting with an exit status
- Restarting the pod will remove any ephemeral containers
