Export WORKLOAD_IMAGE in upgrade e2e steps

[ugreener]

Problem

The medik8s E2E test infrastructure establishes a single source of truth for the workload image: the medik8s-lib CI step writes it to SHARED_DIR/workload_image, and each e2e-test step exports it as WORKLOAD_IMAGE. This allows the image to be changed in one place (medik8s-lib-commands.sh). The upgrade CI variant's e2e-upgrade-test steps did not export WORKLOAD_IMAGE, so they bypassed the centralized configuration entirely. As a result, upgrade tests silently used a fallback image instead of the shared one, and changing the image in medik8s-lib had no effect on upgrade runs.

Summary

Export WORKLOAD_IMAGE from SHARED_DIR/workload_image in both upgrade e2e-upgrade-test steps (presubmit and periodic), matching the pattern already used across all e2e-test steps in the 4.22-konflux variant (PR #82523).

Changes

• Updated presubmit e2e-upgrade-test step to export WORKLOAD_IMAGE from SHARED_DIR/workload_image before make run-tests
• Updated periodic e2e-upgrade-test step with the same pattern

Walkthrough

The presubmit and scheduled AWS upgrade test commands now conditionally load SHARED_DIR/workload_image into WORKLOAD_IMAGE before running make run-tests.

Changes

AWS upgrade workload image

Layer / File(s)	Summary
Load workload image before upgrade tests ci-operator/config/medik8s/system-tests/medik8s-system-tests-main__4.22-upgrade.yaml	Both AWS upgrade test commands use multiline shell scripts. Each command conditionally reads the shared workload image before running tests.

Out of Scope Changes check	✅ Passed	Check skipped because no linked issues were found for this pull request.
Stable And Deterministic Test Names	✅ Passed	The commit changes only one YAML configuration file to export WORKLOAD_IMAGE; it adds no Ginkgo test titles or dynamic test-name values.
Test Structure And Quality	✅ Passed	The commit changes only one CI YAML file and adds WORKLOAD_IMAGE loading to two shell commands; it changes no Ginkgo It blocks or test setup, cleanup, waits, or assertions.
Microshift Test Compatibility	✅ Passed	The PR changes only a CI YAML file to set WORKLOAD_IMAGE; it adds no Ginkgo tests or MicroShift-incompatible API references.
Single Node Openshift (Sno) Test Compatibility	✅ Passed	The patch changes only one CI YAML file and adds no Ginkgo tests or test logic, so SNO compatibility checks do not apply.
Topology-Aware Scheduling Compatibility	✅ Passed	The commit changes only CI YAML commands to load WORKLOAD_IMAGE; it adds no manifests, operator code, controllers, replicas, affinities, selectors, tolerations, or other scheduling constraints.
Ote Binary Stdout Contract	✅ Passed	The patch changes only CI YAML; it adds shell environment setup before make run-tests and contains no OTE binary or process-level stdout writes.
Ipv6 And Disconnected Network Test Compatibility	✅ Passed	The commit changes only YAML commands for WORKLOAD_IMAGE and adds no Ginkgo tests or networking code; the IPv6/disconnected check is not applicable.
No-Weak-Crypto	✅ Passed	The only changes load WORKLOAD_IMAGE and run make run-tests; no MD5, SHA1, DES, RC4, 3DES, Blowfish, ECB, custom crypto, or secret comparisons were introduced.
Container-Privileges	✅ Passed	The PR only changes two shell command blocks to load WORKLOAD_IMAGE; no privileged, hostPID, hostNetwork, hostIPC, SYS_ADMIN, root, or allowPrivilegeEscalation setting is added.
No-Sensitive-Data-In-Logs	✅ Passed	The changed blocks only read and export WORKLOAD_IMAGE before make run-tests; the sole writer sets a public UBI image, and the diff adds no password, token, PII, or logging call.
Description Check	✅ Passed	Check skipped - CodeRabbit’s high-level summary is enabled.
Title check	✅ Passed	The title clearly describes exporting WORKLOAD_IMAGE in the upgrade end-to-end test steps.
