lookout cloud ipspace

Pod/Service/node CIDR utilization per subnet, judged: warning at 80%, critical at 95% — IP space is incompressible, an exhausted range fails the next node or pod block outright. Consumption rate/ETA lives in the sentinel’s capacity source.

MCP tool: k8s_cloud_ipspace

Usage

lookout cloud ipspace [flags]

Flags

Flag	Type	Default	Meaning
--all	bool	—	exploratory dump: emit every range regardless of utilization (info severity below 80%), sorted by pct descending

Common flags (every lookout command)

Flag	Type	Default	Meaning
--namespace	string	—	limit the scan to one namespace
-A	bool	—	scan all namespaces
--workload	string	—	target one workload as <Kind>/<namespace>/<name>, e.g. Deployment/prod/api
--since	duration	—	how far back to look (0 = command default)
--format	string	logfmt	output format: logfmt|json (one record per line either way)
--timeout	duration	10s	abort the invocation after this long (exit 1)
--kubeconfig	string	—	path to a kubeconfig file, instead of $KUBECONFIG / ~/.kube/config
--context	string	—	kubeconfig context to read, instead of its current-context. Selects a cluster for THIS invocation only — nothing is written back — so concurrent invocations can target different clusters. Reported as context=<name> in the summary line
--exemptions	string	—	path to a git-reviewed exemption file (YAML); covered findings are ANNOTATED with their reason and expiry and counted as exempt=<n> in the summary, never dropped

Finding kinds

Every kind= this command can emit, and the severities it carries them at. Nothing else appears in its output; a kind absent from a run means the check looked and found nothing. See the finding-kind glossary for the whole vocabulary.

Kind	Severity	Claim
ipspace.range	critical, warning, info	a pod/service/node range is at 80% of its CIDR or worse; critical from 95%, info for a range the cloud APIs cannot rate and for an —all row below the line
cloud.unavailable	info	the cloud capability this check needs is unavailable, so nothing was examined — an explicit degradation record, never silence

Output fields

Beyond the shared envelope fields (kind, severity, namespace, kind_of_object, name, reason, message, fingerprint, exempt_reason, exempt_expires):

Field	Meaning
cidr	the range’s CIDR block
purpose	what the range allocates: pods, services, or nodes
used	allocated addresses (for GKE pod ranges: addresses of the per-node blocks already carved out — the granularity at which the range actually exhausts)
capacity	usable addresses in the range
pct	used as a percent of capacity, one decimal
capability	cloud.unavailable: the provider capability this command needed (ipspace)
provider	cloud.unavailable: the provider that was asked
unavailable	summary-line note: why the cloud read could not be served

Output contract

Output: one finding per line (logfmt; —format=json for one JSON object per line), keys in fixed order; healthy resources emit nothing. The final line is always the summary: scanned= findings= elapsed= — findings=0 with a summary present means “scanned and healthy”; a stream without a summary line is void. Exit 0 data, 1 runtime error (diagnostics on stderr only), 2 usage.
