SSL Certificates
Web certificates facilitate traffic between a web browser and a web server to be encrypted, and ensure that only the server can read the contents of the traffic.

Local Certificates
During development, it helps to replicate encryption the way it will be used in production. However, for local services you won't have a certificate signed by a public certificate of authority provider (CA).
Let's Encrypt recommends the following:

Unfortunately, in Chrome browsers, this leads to all sorts of issues.
Even when importing the certificates in Chrome -> Settings -> Security -> Manage Certificates

Cypress
Testing with Cypress opens up a few additional challenges.
So far I have not been able to test a local service with a self-signed certificate using Chrome browsers. Firefox works.
I mounted the generated certificates so they are available within the Cypress container (in docker-compose.yml
)

A long thread about getting Chrome to work -- wasn't able to get this working.
