Create bootnode for private network

[singhsourav73]

I am trying to create a private network using the chart. I am trying to automate that peers can add each other. Because of which I cannot use the admin.addPeer() command. I need to bootstrap a Bootnode so that each node to connect to the others.
Is it possible to create a Bootnode for a private network using the chart? If so, could you elaborate what are the configuration changes needed to be done for it?
Any other viable solution is also welcome.

I recommend checking out the geth docs.

The chart right now is more designed for a standalone node but I could imagine potentially extending it where one deploys multiple replicas as peers and a bootnode.
