Docker ca-certificates Dependency Required by Prisma

When I tried to run prisma within a docker container, I got this error:

Error opening a TLS connection: error:1416F086:SSL routines:tls_process_server_certificate:certificate verify failed:../ssl/statem/statem_clnt.c:1919: (unable to get local issuer certificate)

The docker image I used was oven/bun, but I believe this error can happen to any docker image that doesn't install ca-certificates.

The solution is simple, add the following to the Dockerfile

RUN apt update && apt install -y ca-certificates

What is ca-certificates

https://packages.debian.org/sid/ca-certificates

Contains the certificate authorities shipped with Mozilla's browser to allow SSL-based applications to check for the authenticity of SSL connections.

Browsers like chrome or firefox have built-in trusted certificate authorities, which means they can communicate to verify the authenticity of SSL connections. When your prisma connect requires SSL connection, then you have to install ca-certificates to allow SSL-based applications to check for the authenticity of SSL connections.
