This is an easy way to access any of the pod services or pods from an external network. Below are instructions on how to setup a SOCK5 proxy server and then how to configure Firefox running on a desktop to use the proxy server.
The SOCK5 proxy server app is the ssh “Dynamic port forwarding” feature. To enable it, a ssh session must be created with a pod using the ‘-D’ option. The below instructions where tested in ONAP Amsterdam and use the portal-vnc pod.
First connect to your portal-vnc pod.
On the portal-vnc pod Install openssh-server and just use the factory settings
On the portal-vnc pod, copy over a public ssh key. For details on ssh key pair see https://www.digitalocean.com/community/tutorials/how-to-set-up-ssh-keys--2
To be able to create a ssh session from a client external to kubernetes, a NodePort must be created for the session to pass through. So on a box running the kubectl client , Create the following file and fill in the NAMESPACE and NODE-PORT.
Create the Service in kubernetes
Start the sock 5 proxy server by opening a ssh session to the portal-vnc with Dynamic port forwarding enabled (-D).
On the host where the ssh private key resides, executed the following command with the appropriate values. The address of the proxy server will be 'socks5://localhost:PROXY-PORT' where localhost is where the ssh session is initiated from.
This will behave like a regular ssh session to portal-vnc.
Closing the ssh session will close the proxy server too.
Get the service IPs from portal-vnc from its the /etc/hosts file.
Then add host ip mappings to the /etc/hosts where the ssh session was initiated from.
Don't just copy and paste the ip from this block post. The IPs are different on each ONAP deployment
The proxy server can be configured with most web bowsers. Here is an easy way to configure it in Firefox. Just open Firefox preferences by typing 'about:preferences' in the address bar. Then search for proxy and click on the settings button that appears. Finally enter the SOCKs details.
The port 32003 in the following screen shot is the-D <PROXY-PORT> it the entered in the ssh command above.
Once configured just enter the 'http://portal.api.simpledemo.onap.org:8989/ONAPPORTAL/login.htm' and then firefox will open up the ONAP portal. Firefox will have access to any of the onap service IP. Firefox must run on the same host where the ssh session was initiated from and were the /etc/hosts modified.
