Deployment Status

Analyzing the current status of a Kubernetes Deployment


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: (Required) The name of the deployment to check

namespace: (Required) The namespace to look for the deployment in.

Example Analyzer Definition

apiVersion: troubleshoot.sh/v1beta2
kind: Preflight
metadata:
  name: api-deployment-running
spec:
  analyzers:
    - deploymentStatus:
        name: api
        namespace: default
        outcomes:
          - fail:
              when: "< 1"
              message: The API deployment does not have any ready replicas.
          - warn:
              when: "= 1"
              message: The API deployment has only a single ready replica.
          - pass:
              message: There are multiple replicas of the API deployment ready.

Note: troubleshoot.sh/v1beta2 was introduced in preflight and support-bundle krew plugin version 0.9.39 and Kots version 1.19.0. Kots vendors should read the guide to maintain backwards compatibility.
