We recently upgraded the Dynatrace Operator to v1.8.1 on OpenShift. After the upgrade OneAgent pods are failing to start and remain in Init:ErrImagePull / ImagePullBackOff state. From the documentation, we understand that newer operator versions add an init container to the OneAgent pods, which appears to be pulling the dynatrace-operator:v1.8.1 image.
The failure is due to an image pull timeout from registry.connect.redhat.com (i/o timeout on port 443), which suggests a network or registry access limitation on worker nodes. The operator pod itself is running, but the OneAgent init container cannot pull the required image.
