Deployment Status

The deploymentStatus analyzer is used to report on the number of replicas that are "Ready" in a deployment. The when attribute supports standard comparators to compare the number of ready replicas.

The deploymentStatus analyzer uses data from the clusterResources collector. The clusterResources collector is automatically added and will always be present.

The target deployment can be identified by name. The outcomes on this analyzer will be processed in order, and execution will stop after the first outcome that is truthy.

Parameters

name: (Optional) The name of the deployment to check. If name is omitted, all deployments will be analyzed.

namespace: (Optional) The namespace to look for the deployment in. If specified, analysis will be limited to deployments in this namespace.

namespaces: (Optional) The namespaces to look for the deployment in. If specified, analysis will be limited to deployments in these namespaces.
