LetsEncrypt Certificates to RPi

[johngc]

I am running the LetsEncrypt docker and access a couple of dockers on my UNRAID server using https. I have now set up a Raspberry Pi with HomeAssistant on it and would  like to be able to access it securely but am a bit confused about the whole ssl thing. Can I just copy the certificate across to the RPi from my UNRAID Server and then port forward on my router or do I need to run another instance of LetsEncrypt on the RPi?

 

If I can copy it, is there an easy way to automate it every time the UNRAID docker upgrades?

 

I have tired a bit of googlefu but I am not sure what I am actually asking!
