Viewing the state of the Che cluster deployment using OpenShift 4 CLI tools

This section describes how to view the state of the Che cluster deployment using OpenShift 4 CLI tools.

Prerequisites

An instance of Eclipse Che running on OpenShift.
An installation of the OpenShift command-line tool, oc.

Procedure

Run the following commands to select the che project:
```
$ oc project <project_name>
```
Run the following commands to get the name and status of the Pods running in the selected project:
```
$ oc get pods
```

Check that the status of all the Pods is Running.

Example 1. Pods with status Running

NAME                            READY     STATUS    RESTARTS   AGE
che-8495f4946b-jrzdc            0/1       Running   0          86s
che-operator-578765d954-99szc   1/1       Running   0          42m
keycloak-74fbfb9654-g9vp5       1/1       Running   0          4m32s
postgres-5d579c6847-w6wx5       1/1       Running   0          5m14s

To see the state of the Che cluster deployment, run:

$ oc logs --tail=10 -f `(oc get pods -o name | grep operator)`
