How do I configure Misskey for testing on my local machine?

[taraxos]

This is my first time trying something like this out so I may be missing something obvious. I've followed the instructions for installing and setting up Misskey with Docker and it seems to build fine (or at least without any obvious error messages), but I'm not sure what settings to use in default.yml or docker-compose.yml (or any other relevant configuration files) for local testing.

I've tried using https://localhost/ and https://127.0.0.1/ for the url in default.yml and uncommented port: 443 and key and cert, then ran as root, but haven't been able to connect via browser. Here are the last settings I tried:

#━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
# Misskey configuration
#━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

#   ┌─────┐
#───┘ URL └─────────────────────────────────────────────────────

# Final accessible URL seen by a user.
url: https://localhost/

# ONCE YOU HAVE STARTED THE INSTANCE, DO NOT CHANGE THE
# URL SETTINGS AFTER THAT!

#   ┌───────────────────────┐
#───┘ Port and TLS settings └───────────────────────────────────

#
# Misskey supports two deployment options for public.
#

# Option 1: With Reverse Proxy
#
#                 +----- https://example.tld/ ------------+
#   +------+      |+-------------+      +----------------+|
#   | User | ---> || Proxy (443) | ---> | Misskey (3000) ||
#   +------+      |+-------------+      +----------------+|
#                 +---------------------------------------+
#
#   You need to setup reverse proxy. (eg. nginx)
#   You do not define 'https' section.

# Option 2: Standalone
#
#                 +- https://example.tld/ -+
#   +------+      |   +---------------+    |
#   | User | ---> |   | Misskey (443) |    |
#   +------+      |   +---------------+    |
#                 +------------------------+
#
#   You need to run Misskey as root.
#   You need to set Certificate in 'https' section.

# To use option 1, uncomment below line.
#port: 3000    # A port that your Misskey server should listen.

# To use option 2, uncomment below lines.
port: 443

#https:
#  # path for certification
key: /etc/letsencrypt/live/localhost/privkey.pem
cert: /etc/letsencrypt/live/localhost/fullchain.pem

I've also tried this config for docker-compose.yml (https://git.yeet.st/cybermelon/misskey/src/commit/b1e70105cdfe990af65fc6cc702b13716a4efcf5/docker-compose.yml) that I came across for building and running for localhost, but that didn't work either.

What am I getting wrong? Thanks for your help.

Finally got it to work! :) For anyone else who might run into this issue for whatever reason, in default.yml set the url to http://localhost:3000/ and set the port to 3000, and in docker-compose.yml set ports to "3000:3000" instead of "127.0.0.1:3000:3000". Thanks to @mei23 for your help.
