Docker with SSL and an nginx reverse proxy

Running your ASP.NET Core (or other) application in Docker using SSL should not be an overwhelming task. These steps should do the trick.

Run the following steps from a Linux terminal (I used WSL or WSL2 on Windows from the Windows Terminal).

1. Create a conf file with information about the cert you'll be creating

It should look something like the content below; call it my-site.conf or something like that.

quangthe

server {
  listen 80;
  server_name www.example.com example.com;

  # Redirect all traffic to SSL
  rewrite ^ https://$server_name$request_uri? permanent;
}

server {
  listen 443 ssl default_server;

Generate ssl certificates with Subject Alt Names on OSX

Open ssl.conf in a text editor.

Edit the domain(s) listed under the [alt_names] section so that they match the local domain name you want to use for your project, e.g.

DNS.1   = my-project.dev

Additional FQDNs can be added if required:

quangthe

function (user, context, callback) {
  var namespace = 'https://tojs.io/';
  context.accessToken[namespace + 'user_authorization'] = {
    groups: user.app_metadata.groups,
    roles: user.app_metadata.roles,
    permissions: user.app_metadata.permissions
  };
  return callback(null, user, context);
}
