mkcert

mkcert is a simple tool for making locally-trusted development certificates. It requires no configuration.

** Alternative Method(Recommended)**: Use localhost.direct and certs provided at this site instead of mkcert This approach even works, when you don't have admin access to company issued MacBook.

Install

brew install mkcert

Setup

# NOTE: sudo is needed
mkcert -install
# this will create root CA cert into: `mkcert -CAROOT` output
mkcert -CAROOT
ls -1 ~/Library/Application\ Support/mkcert 

Create Certs

for example if you want to create certs for traefik:

Decide on your URL scheme like *.nip.io, localhost.direct, *.localhost, *.vcap.me, or even *.bret.lol

cd  infra/traefik
mkdir certs && cd certs 

mkcert -cert-file localhost.direct-cert.pem -key-file localhost.direct-key.pem \
"*.localhost.direct" localhost 127.0.0.1 ::1

Reminder: X.509 wildcards only go one level deep, so this won't match a.b.localhost.direct

Usage

Used to setup https on localhost for Vite, SvelteKit project

Reference

• Available Public Wildcard DNS Domains pointing to localhost (127.0.0.1)

• localhost.direct
