OCPNETUI-117: Add additional views to the topology view - #667
Adds logical scope views to the networking topology visualization, based on the scope and display patterns used by NetObserv while keeping the networking console plugin backed by Kubernetes API resources.
This is a suggested UX that align with netobserv implementation.
Feel free to pick whatever you want and do your own if we are not aligned.
Implemented
Topology scopes
Adds the following scopes in the requested order:
Network
Namespace
Owner
Resource
The Resource scope is the default. Scope changes rebuild the topology model, preserve the original cluster-scoped resources where appropriate, and automatically re-layout and fit the graph so the new view is not left outside the viewport.
Scope behavior includes:
Network scope showing logical network resources and their connections.
Namespace scope replacing namespaced resources with their existing namespaces while retaining cluster-scoped resources.
Owner scope replacing resources with controller owners when an owner is available and retaining ownerless resources unchanged.
Safe handling of missing names and namespaces without rendering undefined identifiers.
Grouping
Adds independent grouping controls for:
None
Namespace
Namespace + Owner
Owner
Grouping is kept separate from scope selection. Invalid combinations are filtered out, including owner grouping for Network and Namespace scopes. Namespace + Owner is available for Resource scope and produces nested groups. The Groups dropdown is disabled when only None is available.
Groups are collapsible and display an icon when collapsed. Group filtering keeps empty groups out of the model.
Display options and controls
Scope and Groups selectors are integrated into the existing Display Options dropdown.
The selectors use compact dropdowns and remain responsive on narrow layouts.
Display options remain open after selecting values.
Existing visibility switches are interactive.
Filter rows have improved spacing and preserve the dropdown state.
The existing topology legend button now opens a legend popover.
The legend displays active node kind abbreviations/colors and active edge relationship definitions, including aggregated connections created by logical scopes.
Kubernetes model metadata and badges
Node badges use Kubernetes model abbreviations from the Console model registry through useK8sModels().
NetObserv-compatible color overrides are applied for common Kubernetes kinds such as Pods, namespaces, Deployments, ReplicaSets, DaemonSets, Jobs, Services, Ingresses, and VMs.
Missing model colors use the same fallback behavior as NetObserv.
Namespace, owner, and network scope nodes receive badges based on their projected Kubernetes kind.
Pod badges use the model abbreviation P and the blue-green color from the NetObserv model definitions.
Status decorators remain available and their click handler is now safe instead of invoking an undefined callback.
Icons
Consolidates the topology-specific custom SVG icons into TopologyIcons.tsx.
Reuses the NetObserv-inspired Pod and owner-kind icon paths.
Owner icons are selected by owner kind where supported, including Deployment, Job, DaemonSet, ReplicaSet, and StatefulSet.
Network, namespace, owner, resource, and collapsed-group icons are handled through the shared topology icon component.
Data transformation and robustness
Applies resource filters before scope projection so filtered Pods can still be represented by their owners in Owner scope.
Keeps ordinary edges without custom edge aggregation.
Adds scope-projected edges with an explicit aggregated-connection relationship.
Guards layout bounds and missing node dimensions to avoid width/height runtime errors, including Cola layout.
Improves the Levels layout handling of empty or incomplete group dimensions.

Walkthrough
The topology view adds scope and grouping controls, transforms Kubernetes resources into scoped graph models, and updates graph filtering, layout, icons, and legend presentation. The changes also add topology fixtures, a VirtualMachine CRD, and locale entries for the new labels and descriptions.

RuntimeDefault seccomp profile. Keep the settings consistent across pause
containers and match each container entry’s indentation.
Review comments at @src/views/topology/components/ScopeSlider.tsx:

- Line 205: Update the enum comparisons in the Topology logic involving
currentGroup and nextScope, and value and scope, to compare their string
representations so TypeScript accepts the distinct enum types. Preserve the
existing comparison operators and behavior.
Review comments at @src/views/topology/components/TopologyIcons.tsx:
- Around line 129-130: Update TopologyOwnerIcon so the default branch renders
GrMultiple directly, outside the scaled SVG group. Apply the scale wrapper only
to custom path content, preserving the existing scaling for those glyphs.

- Around line 358-366: Update owner identity generation in getOwnerGroup and its
use in createScopedModel and addGroups to include node.data?.namespace,
preventing same-named owners in different namespaces from sharing identity
values. Keep scopeKey and the displayed label as kind/name for the existing icon
behavior. Pass the computed namespace-qualified id to createScopeNode so it
matches the nodeToScopedNode mapping.
- Around line 275-276: Update the scope-node aggregation around createScopeNode
so each later member with the same scopedId can raise the aggregate to the worse
status, rather than leaving status dependent on which member is processed first.
Compare statuses using their established severity ordering and keep the scope
node’s status and displayed data status consistent.
Review comments at @src/views/topology/utils/filterModel.ts:
- Around line 89-96: Update modelWithNodes so search results exclude group nodes
before building the returned node list, preventing duplicate group IDs. Resolve
retained groups iteratively so parent groups can retain nested groups, then
recompute each retained group’s children from the resolved IDs; preserve the
existing edge filtering and return leaf nodes alongside each group only once.

Disable service-account token mounts for the fixture Pods.
The new container security contexts do not prevent Kubernetes from mounting the default service-account token. The pause containers do not need API credentials. Set automountServiceAccountToken: false in each Pod spec and workload Pod template. Kubernetes mounts the token by default unless the Pod or ServiceAccount disables it. (kubernetes.io)
As per path instructions, “automountServiceAccountToken: false unless needed”.

automatic service-account token mounting, while leaving any unrelated resource

Prune group children when hiding workloads.
With Namespace grouping, enable Hide workloads while search and advanced filters are empty. applyHideWorkloads in src/views/topology/utils/filterModel.ts, Lines 458–474, removes Pod/VM nodes but retains their IDs in group.children. The other filters then return the model unchanged. (raw.githubusercontent.com)
PatternFly 6.6.0 Visualization.fromModel recursively resolves those child IDs. A removed child resolves to undefined, so accessing element.children throws and breaks the topology view. (raw.githubusercontent.com)
Make applyHideWorkloads use the group-aware pruning in modelWithNodes before loading the model.
