Unable to self-host on Azure

[slaby93]

Hey folks!
I'm trying to host Mailcarrier on Azure.

Here are env variables I use

SSL_MODE: mixed
      MAILCARRIER_AUTH_GUARD: auth:sanctum
      APP_NAME: ARC XYZ Mailcarrier
      APP_ENV: local
      APP_KEY: base64:XXX
      APP_DEBUG: true
      MAIL_MAILER: smtp
      MAIL_HOST: smtp.azurecomm.net
      MAIL_PORT: 587
      MAIL_ENCRYPTION: tls
      MAIL_USERNAME: XXX
      MAIL_PASSWORD: XXX
      MAIL_FROM_ADDRESS: DoNotReply@XXX

Problem I face is with Ingres. I have https but for whatever reason something (I guess NGINX?) rewrite my requests to HTTP. This is breaking whole application because when I try to generate API key for my backend app, I can't because I can't fetch JavaScript file required to handle click on the button.

All help appreciated <3

I found an answer
I had to create my own image based on mailcarrier image.

Generally speaking I've added to NGINX new port 5555 which forces all traffic to port 443
On Azure Ingres, I'm targeting port 5555. All works like a charm.

Dockerfile:

FROM mailcarrier/mailcarrier:latest
EXPOSE 80
EXPOSE 443
COPY nginx.conf /etc/nginx/nginx.conf
EXPOSE 5555

nginx.conf

user webuser webgroup;
worker_processes auto;
pid /run/nginx.pid;
daemon off;

events {
    worker_connections 768;
    # multi_accept on;
}

http {

    ##
    # Basic Settings
    ##

    sendfile on;
    tcp_nopush on;
    tcp_nodelay on;
    keepalive_timeout 65;
    types_hash_max_size 2048;
    server_tokens off;

    # server_names_hash_bucket_size 64;
    # server_name_in_redirect off;

    include /etc/nginx/mime.types;
    default_type application/octet-stream;

    ##
    # SSL Settings
    ##

    ssl_protocols TLSv1.2 TLSv1.3; # Dropping SSLv3, ref: POODLE
    ssl_prefer_server_ciphers on;

    access_log /dev/stdout;
    error_log /dev/stderr;

    http2_max_field_size 16k;
    http2_max_header_size 32k;

    ##
    # Virtual Host Configs
    ##

    include /etc/nginx/conf.d/*.conf;
    include /etc/nginx/sites-enabled/*;

    ##
    # Redirect port 5555 to 443
    ##
    server {
        listen 5555;

        location / {
            proxy_pass https://localhost:443;
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Forwarded-Proto $scheme;
        }
    }
}
