Hi @balintTobik , thanks for this. two comments for you.
The operator does not yet propagate the cluster-wide Proxy object to CAA, so peer-pods can't reach the cloud provider API in restricted network (CAA has no HTTP_PROXY, gets a context-deadline-exceeded timeout talking to management.azure.com). Work around it here by wiring HTTP_PROXY/HTTPS_PROXY/NO_PROXY into CAA via the existing providersConfigs.all passthrough (same mechanism already used for VXLAN_PORT/PROXY_TIMEOUT). This commit exists so it can be reverted as a single unit once openshift/sandboxed-containers-operator#2839 (proxy propagation to CAA) merges - the operator will set these env vars itself and this workaround becomes redundant.

When the operator runs behind an HTTP proxy (e.g. via OLM proxy injection), child workloads need the same proxy configuration to reach cloud APIs and container registries. Add getProxyEnvVars() helper that forwards HTTP_PROXY, HTTPS_PROXY, and NO_PROXY from the operator pod environment into the CAA DaemonSet and PodVM image builder Job containers.

- Around line 206-208: Update configureCAA to return errors from
generateTrustedCAVolumeConfig instead of logging and continuing, while
preserving the existing NotFound fallback. Propagate configureCAA’s error
through the CreateOrUpdate callback in enablePeerPodsMiscConfigs so
reconciliation receives non-NotFound failures and retries.

- Line 613: Replace the focused ginkgo.FIt declaration with ginkgo.It in the
test named “C00000-verify proxy and trusted CA propagation to CAA and PodVM jobs
[Serial]”, preserving the test body and its normal sig-kata filtering behavior.
- Line 716: Update the test setup and deferred cleanup around restorePatch to
snapshot the existing Subscription/sandboxed-containers-operator.spec.config
before applying the test change, then restore that exact value instead of
unconditionally setting config to null. Preserve null when the original
configuration is absent and retain all unrelated configuration fields during
cleanup.
- Around line 662-724: The test setup around the trusted-ca ConfigMap must
handle pre-existing resources: check whether trusted-ca already exists before
creation, reuse it while preserving its original contents, and restore it
afterward; only create and delete the ConfigMap when it was absent initially.
Update the setup and deferred cleanup around the trusted-ca creation before the
daemonset deletion, while preserving the existing proxy and volume patch flow.

For PodVM jobs, also set REQUESTS_CA_BUNDLE so Python-based tools (Azure CLI) use the custom CA bundle.

OpenShift config.openshift.io NetworkStatus serviceNetwork clusterNetwork machineNetwork dual stack multiple entries API
💡 Result:
<search_synthesis>
In OpenShift, the configuration of network address pools is handled through the config.openshift.io API group for cluster-wide settings and the operator.openshift.io API group for the Cluster Network Operator (CNO) [1][2]. For dual-stack networking, OpenShift supports multiple entries in the clusterNetwork field, which allows for both IPv4 and IPv6 address blocks to be defined [2]. While the API structure for serviceNetwork is an array of strings to accommodate future growth, current implementations typically support a single entry or a combined dual-stack definition [3][4]. Key technical details regarding these configurations include: 1. ClusterNetwork: This field is defined as an array of ClusterNetworkEntry objects [3][5]. When configuring dual-stack networking, you explicitly add both an IPv4 and an IPv6 CIDR block to this list [2]. The host prefix must be set appropriately (e.g., /64 or greater for IPv6) to ensure proper pod IP allocation [6][7]. 2. ServiceNetwork: Although represented as an array of strings in the API, documentation notes that support for multiple entries is limited or functionally restricted to a single entry in most current network plugins, even if the API allows the array structure [3][5][4]. In dual-stack environments, you specify both IPv4 and IPv6 ranges within the configuration [2]. 3. NetworkStatus vs. Spec: The spec fields in config.openshift.io/v1 are generally immutable after installation [8][5]. Administrators are advised to consume the status field in the Network configuration object to observe the currently deployed configuration, as spec reflects user-settable values that may not represent the active state [8][9]. 4. Dual-Stack Conversion: Converting a single-stack cluster to dual-stack involves patching the Network custom resource [6][10]. When performing this conversion, the order of address families in your configuration must match the specific dual-stack configuration selected for your infrastructure (e.g., AWS dual-stack primary configurations) [2]. In summary, while the API definitions permit arrays for clusterNetwork and serviceNetwork, their usage is governed by the capabilities of the underlying network plugin (e.g., OVN-Kubernetes) and immutability rules that apply post-installation [3][5][2]. Always reference the status field for the cluster's actual active network configuration [8].

Include all cluster network CIDRs in NO_PROXY.
NetworkStatus.clusterNetwork is an array, and dual-stack clusters use IPv4 and IPv6 entries. Reading only clusterNetwork.0.cidr omits later entries. Because noProxyTest is also the expected value in the CAA and PodVM assertions, the test can pass without checking propagation of the omitted CIDR. Collect every clusterNetwork[*].cidr before constructing noProxyTest.

Assert the complete trusted CA wiring.
The CAA DaemonSet and PodVM queries check only the trusted-ca volume and mount names. The PodVM query checks only that REQUESTS_CA_BUNDLE exists. These checks can pass if the ConfigMap name or key, tls-ca-bundle.pem path, mount path, readOnly setting, or REQUESTS_CA_BUNDLE value is wrong.
Replace the name-only checks at both resource sites with exact assertions for the ConfigMap trusted-ca, key ca-bundle.crt, tls-ca-bundle.pem, mount path /etc/pki/ca-trust/extracted/pem, and readOnly: true. Assert the PodVM value is /etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem.

In `@test/e2e/kata_test.go` at line 839, Update the trusted CA assertions in the
CAA DaemonSet and PodVM checks to validate the complete wiring, not just
resource names: ConfigMap trusted-ca, key ca-bundle.crt, tls-ca-bundle.pem,
mount path /etc/pki/ca-trust/extracted/pem, and readOnly true. Also assert
REQUESTS_CA_BUNDLE equals /etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem
instead of only checking its presence.

The operator does not yet propagate the cluster-wide Proxy object to CAA, so peer-pods can't reach the cloud provider API in restricted network (CAA has no HTTP_PROXY, gets a context-deadline-exceeded timeout talking to management.azure.com). Work around it here by wiring HTTP_PROXY/HTTPS_PROXY/NO_PROXY into CAA via the existing providersConfigs.all passthrough (same mechanism already used for VXLAN_PORT/PROXY_TIMEOUT). This commit exists so it can be reverted as a single unit once openshift/sandboxed-containers-operator#2839 (proxy propagation to CAA) merges - the operator will set these env vars itself and this workaround becomes redundant.

- Line 631: Update the oc queries in the e2e test around the network.config,
subscription, DaemonSet counter, and restore-patch handling to use JSON output
for object-valued data consumed by gjson. Prefer -o=json with status/spec paths,
extract spec.config as raw JSON before patching or restoring, and keep JSONPath
only for scalar values.

Verify that proxy env vars (HTTP_PROXY, HTTPS_PROXY, NO_PROXY) and the trusted CA bundle are propagated from the operator to the CAA daemonset and PodVM image creation job. The test patches the Subscription with proxy config and a trusted-ca volume, then asserts the env vars, volumes, volumeMounts, and REQUESTS_CA_BUNDLE appear on the managed workloads.

Propagate HTTP_PROXY, HTTPS_PROXY, and NO_PROXY environment variables from the operator pod to child workloads that make outbound network calls:
Ref.: KATA-5934
- Description of the problem which is fixed/What is the use case
- What I did
- How to verify it
Set cluster proxy and check if it's propagated to CAA daemonset and podvm creation/deletion job.
- Description for the changelog
When the operator runs behind an HTTP proxy (e.g. via OLM proxy
injection), child workloads need the same proxy configuration to
reach cloud APIs and container registries. Add getProxyEnvVars()
helper that forwards HTTP_PROXY, HTTPS_PROXY, and NO_PROXY from
the operator pod environment into the CAA DaemonSet and PodVM
image builder Job containers.
