Installing the control plane pulls roughly 570MB of third-party images (postgres, prometheus, the otel collector, rustfs, envoy, jaeger) onto a single node. kubelet serializes image pulls by default, so they queue behind one another and whichever workload lands at the back of the queue can miss its readiness deadline: e2e has failed with postgres still in PodInitializing after 60s, its image not yet pulled, while everything else was already running.

e2e has failed repeatedly with postgres still in PodInitializing after 60s, its image not yet pulled, while everything else was already running.
