title: Can I use my own Certificate Authority for HTTPS over LAN?
body: <p>I have a server and a few clients, all running on different docker containers. The users can use the client by entering localhost:3000 on their browser (where the client docker is running).
  All the containers run on the same LAN. I want to use HTTPS.
  Can I sign a public private key pair using my own CA, then load the CA's public key to the browser?
  I want to use the normal flow for public domains, but internally with my own CA.
  Or should I look for another solution?</p>
