I have explored and found that we need to modify /srv/nginx to remove self signed certs and add our own certs using LetsEncrypt or any other source.
It would be helpful if u can answer following qns
1.Which files do i need to replace?
2. Steps to do after replacing files ?
3.Do i need to create certs and keys in docker container or in generate in our local machine and pasting them in container is fine ?
Look for these files inside the docker container, replace them with your certificates, and restart the container.
You can generate the key and certs anywhere and copy them into the container.
[PMM-1566] Add LetsEncrypt support to PMM Server - Percona JIRA Also Gone through this while browsing queries.
It would be nice if this feature request can be resolved instead of creating certs on their own
