Starting Engineering Lifecycle Management application pods by using Red Hat OpenShift CLI and Kubernetes CLI

When you update an existing Engineering Lifecycle Management instance configuration, you must start the Engineering Lifecycle Management application pods to reflect the changes. Use the following procedure to start the application pod by using the Red Hat® OpenShift® or Kubernetes CLI method. It helps you to start the application pods of selected Engineering Lifecycle Management applications or all applications in the Engineering Lifecycle Management instance.

Procedure

Draft a YAML configuration to start the application pods with a name start-all-apps.yaml

apiVersion: elm.ibm.com/v1 
kind: ELMOperation 
metadata: 
  name: start-all-apps 
  labels: 
    app.kubernetes.io/instance: ibm-elm-operator 
    app.kubernetes.io/managed-by: Go 
    app.kubernetes.io/name: ibm-elm-operator 
    release: 1.0.0 
  namespace: example-namespace
spec: 
  selectedApplications: 
    ccm: false 
    dcc: false 
    gc: false 
    jas: false 
    rb: false 
    jts: false 
    ldx: false 
    lqe: false 
    qm: false 
    eni: false 
    rm: false 
  allApplications: true
  operationType: startApplicationPod

In the example before, operationType must be set as startApplicationPod.

Note: If you want to start only specific applications, add the flag as true for all respective applications. If you want to start all applications, set allApplications as true

Create an ELMOperation instance to start the application pods.
For Red Hat OpenShift, use the following command
```
oc create -f start-all-apps.yaml
```
For Kubernetes, use the following command
```
kubectl create -f start-all-apps.yaml
```
The ELMOperation gets created and appears in the list. To verify the successful creation ELMOperation instance
For Red Hat OpenShift, use the following command
```
oc get ELMOperation -n example-namespace
```
For Kubernetes, use the following command
```
kubectl get ELMOperation -n example-namespace 
```
