Configuring additional ports

Only the application UI ports are open for external access on the services and/or ingress routes, by default, when you deploy Certified Container on a container management platform. You can open additional ports for external access for adapters and other integration points through configurations available for ASI, AC and API application container deployments.

To open an additional ports, you need to configure it in the Helm configuration file (values.yaml) or through the Platform UI.

Add a port mapping for internal pod access for the application deployment (ASI, AC or API).


For example:
asi:
  extraPorts:  
     -name: <internal-port-name> ## my-http-adapter
      port: <internal-port-number> ## 35000
      targetPort: <internal-port-name> ## my-http-adapter
      protocol: TCP

Add a port mapping for external access to the service and/or ingress routes for the applicable application deployment (ASI, AC or API).


For example:
ac:
  service:
    extraPorts: 
       -name: http-1
        port: <service-port-number> ## Can be same as internal port number (35000) or different say 45000.        
        targetPort: <internal-port-name> ## my-http-adapter 
        nodePort: <node-port-number> ## Required only if service type in use is NodePort. Should be in the range 30000-32767.
        protocol: TCP

Note: In case of an HTTP endpoint, for service type LoadBalancer, the external access URL is:


http<or https>://<service public ip>:<service-port-number>/<target uri>

Open the additional ports in container platform

You can open the additional ports in container platform after the Helm installation or deployment is complete in 2 ways:

Helm upgrade: Add the port number in the values.yaml file under services > extra ports and save the changes.
Run
```
helm upgrade -f <values.yaml> <name of the Helm release> <path to upadated helm charts>
```
Port Forward: Use the command line for port forward option available in container platforms.

Kubernetes: Port Forwarding to Access Applications in a Cluster
Openshift: Port Forwarding.

Verify the opened ports

For ASI, AC or API services, you can verify the newly opened ports and their external mapping under the ports column using the below commands:


>Kubectl get service <service name>   - Kubernetes cluster
>oc service <service name>            - OpenShift setup
