Introduction

This section demonstrates how to create the OHS container and OHS nodeport.

The OHS nodeport is the Kubernetes entry port (HTTP/HTTPS) for OHS , for example 31777 (HTTP) and 31443 (HTTPS).

Create the OHS Nodeport

In this section you create the OHS nodeport using the $MYOHSFILES/ohs_service.yaml.

The nodeport is the entry point for OHS. For example http://ohs.example.com:31777 or https://ohs.example.com:31443

Edit the $MYOHSFILES/ohs_service.yaml and make the following changes:
- <NAMESPACE> to your namespace, for example ohsns.
- If you want your OHS node port to listen on something other that 31777 and 31443, change accordingly
- If you are using your own httpd.conf file and have changed the port to anything other than 7777, you must change the targetPort and port to match.
- If you are using your own ssl.conf file and have changed the port to anything other than 4443, you must change the targetPort and port to match.
```
kind: Service
apiVersion: v1
metadata:
  name: ohs-domain-nodeport
  namespace: ohsns
spec:
  selector:
    oracle: ohs
  type: NodePort
  ports:
  - port: 7777
    name: http
    targetPort: 7777
    nodePort: 31777
    protocol: TCP
  - port: 4443
    name: https
    targetPort: 4443
    nodePort: 31443
    protocol: TCP
```
Run the following command to create a Kubernetes service nodeport for OHS.

Note: Administrators should be aware of the following:
- As this is a Kubernetes service the port is accessible on all the worker nodes in the cluster.
- If you create another OHS container on a different port, you will need to create another nodeport service for that OHS.
```
$ kubectl create -f $MYOHSFILES/ohs_service.yaml
```
The output will look similar to the following:
```
service/ohs-domain-nodeport created
```

Validate the service has been created using the command:

$ kubectl get service -n <namespace>

For example:

$ kubectl get service -n ohsns

The output will look similar to the following:

NAME                  TYPE       CLUSTER-IP     EXTERNAL-IP   PORT(S)                         AGE
ohs-domain-nodeport   NodePort   10.98.163.75   <none>        7777:31777/TCP,4443:31443/TCP   22s

Create the OHS Container

In this section you create the OHS container using the ohs.yaml file created in Prepare the ohs.yaml file.

Run the following command to create the OHS container:

$ kubectl create -f $MYOHSFILES/ohs.yaml

The output will look similar to the following:

configmap/ohs-script-configmap created
deployment.apps/ohs-domain created

Run the following command to view the status of the pods:

$ kubectl get pods -n <namespace> -w

For example:

$ kubectl get pods -n ohsns -w

Whilst the OHS container is creating you, may see:

NAME                         READY   STATUS              RESTARTS   AGE
ohs-domain-d5b648bc5-vkp4s   0/1     ContainerCreating   0          2m13s

To check what is happening while the pod is in ContainerCreating status, you can run:

kubectl describe pod <podname> -n <namespace>

For example:

$ kubectl describe pod ohs-domain-d5b648bc5-vkp4s -n ohsns

Once the container is created, it will go to a READY status of 0/1 with STATUS of Running. For example:

NAME                         READY   STATUS    RESTARTS   AGE
ohs-domain-d5b648bc5-vkp4s   1/1     Running   0          3m10s

To check what is happening while the pod is in this status, you can run:

$ kubectl logs -f <pod> -n <namespace>

Once everything is started you should see the OHS is running (READY 1/1):

NAME                         READY   STATUS    RESTARTS   AGE
ohs-domain-d5b648bc5-vkp4s   1/1     Running   0          4m10s

If there are any failures, follow Troubleshooting.

Validating the OHS Container

In this section you validate the OHS container and check you can access OHS using the nodeport.

Validating the OHS container file system

To validate the OHS container file system:

Run the following command to get the name of the OHS container:

$ kubectl get pods -n <namespace>

For example:

$ kubectl get pods -n ohsns

The output will look similar to the following:

NAME                         READY   STATUS    RESTARTS   AGE
ohs-domain-d5b648bc5-vkp4s   1/1     Running   0          5m34s

Run the following command to create a bash shell inside the container:

$ kubectl exec -n <namespace> -ti <pod> -- /bin/bash

For example:

$ kubectl exec -n ohsns -ti ohs-domain-79f8f99575-8qwfh -- /bin/bash

This will take you to a bash shell inside the container:

[oracle@ohs-domain-75fbd9b597-z77d8 oracle]$

Inside the bash shell navigate to the /u01/oracle/user_projects/domains/ohsDomain/config/fmwconfig/components/OHS/ohs1/ directory:
```
cd  /u01/oracle/user_projects/domains/ohsDomain/config/fmwconfig/components/OHS/ohs1/
```
From within this directory, you can navigate around and list (ls) or cat any files you configured using the configmaps.

Validating the OHS nodeport

In this section you validate the OHS nodeport by accessing the OHS URL’s.

In the examples below, ${OHS-HOSTNAME} refers to the hostname.domain of the server where the OHS nodeport was deployed. ${OHS-NODEPORT} refers to the nodePort specified in your ohs-service.yaml, for example 31777for HTTP, or 31443 for HTTPS.

Note: If OHS is accessed via a loadbalancer, replace ${OHS-HOSTNAME} and ${OHS-NODEPORT} with the loadbalancer hostname.domain and port.

If you have any problems accessing the URL’s, refer to Troubleshooting.

Launch a browser and access the following:

Note: If you have deployed OHS with WebGate, then it will depend on your policy setup as to whether the URL’s below are accessible or not.

a) The OHS homepage http(s)://${OHS-HOSTNAME}:${OHS-NODEPORT}.

b) Any other files copied in your ohs-htdocs configmap, for example http(s)://${OHS-HOSTNAME}:${OHS-NODEPORT}/mypage.html.

c) Any files from directories crested under htdocs, for example the ohs-myapp configmap, for example http(s)://${OHS-HOSTNAME}:${OHS-NODEPORT}/myapp.

d) Any URI’s defined for mod_wl_ohs in your httpd.conf, ssl.conf or moduleconf/*.conf files, for example http(s)://${OHS-HOSTNAME}:${OHS-NODEPORT}/console.

e) If WebGate is deployed, any protected applications, for example http(s)://${OHS-HOSTNAME}:${OHS-NODEPORT}/myprotectedapp.
