Obtain Version Information from Kubernetes

You can obtain version and build information for the MATRIXX Engine, while running, with Kubernetes commands.

Before you begin

The YAML manifests for Kubernetes pods, services, and StatefulSets contain MATRIXX Engine version information in the labels section.
Note: While version information can be obtained from any Kubernetes object, in any correctly running MATRIXX Engine deployment, version information is the same for all objects.

Procedure

  1. If you do not know the object names, on the kubernetes master node, run one of the following commands:
    kubectl get pods
    kubectl get svcs
    kubectl get sts
    The object names are shown in the NAME column, as shown in the example output from kubectl get pods below:
    $ kubectl get pods
NAME                READY   STATUS      RESTARTS   AGE
ckpt-s1e1-0         1/1     Running     0          44m
mgr-s1e1            0/1     Completed   0          44m
proc-s1e1-0         1/1     Running     0          44m
publ-s1e1-0         1/1     Running     0          44m
tralb-proc-s1e1-0   1/1     Running     0          44m
tralb-publ-s1e1-0   1/1     Running     0          44m
  2. Obtain version information for an object with one of the following commands, where object_name is the pod, service, or StatefulSet you are inspecting:
    kubectl get pod object_name -n mtx-dev -o yaml
    kubectl get svc object_name -n mtx-dev -o yaml
    kubectl get sts object_name -n mtx-dev -o yaml
    The version information is listed as mtx-version in the labels section. In the following example, the proc-s1e1-0 pod is running version 5122, build 36:
    $ kubectl get pod -n mtx-dev proc-s1e1-0 -o yaml
apiVersion: v1
