Ensure that all containers of Kubernetes deployment resources have proper ephemeral storage limits configured to prevent the instability of other containers.

Motivation

For an elastic and resilient cloud infrastructure, ensure that the over-usage of ephemeral storage of one container doesn't affect any others. Furthermore, if one container exceeds its configured limits, Kubernetes should kill it and eventually prepare it within a given timeframe.

Structure

Verify that a user-visible endpoint responds within the expected success rates while exceeding the ephemeral storage. As soon as one container exceeds the ephemeral storage, by filling the disk in a /tmp directory, Kubernetes should evict the container, decreasing ready pods. Within 60 seconds, the evicted container should run again, and the pod should be ready.
