Event Gateway in Evicted state

Symptoms

When an Event Gateway instance is set up with ephemeral storage, it is possible for it to reach an Evicted state due to running out of space.

Causes

Kubernetes pods use ephemeral storage for scratch space, caching, and for logs. If the logs produced by the Event Gateway are not cleaned up in time, the gateway reaches the Evicted state.

Resolving the problem

You can increase the ephemeral storage available to the Event Gateway, so that additional storage is available to clean up logs. You can add more storage by editing the EventGateway custom resource:

# excerpt from a Event Gateway CRD 
template:
  pod:
    spec:
      containers:
          name: egw
          resources:
            limits:
              ephemeral-storage: 500Mi

This updates the pod’s ephemeral storage for the Event Gateway, which prevents the gateway instance from overloading the storage and reaching the Evicted state.
