Deployment Always use development config, iRedMail Server Loco Config, and SystemD Service Configuration

[bendo01]

Hi,

i've host my loco app in vps using Alma Linux 9.5, i compiled my app using this command

cargo build --release

and use systemd service to run my app

path: /etc/systemd/system/app.service

this is my app.service file

[Unit]
Description=API Server
After=network.target

[Service]
User=bendo01
WorkingDirectory=/usr/share/nginx/html/server
Environment="APP_ENVIRONMENT=production"
Environment="RUST_BACKTRACE=1" # For debugging
ExecStart=/usr/share/nginx/html/server/xsia_loco-cli start -s
# EnvironmentFile=/usr/share/nginx/html/server/.env
Restart=on-failure
RestartSec=3

[Install]
WantedBy=multi-user.targe

but when i run command

sudo systemctl start app.service

then

sudo systemctl status app.service

it's output use config/development.yaml to run app

it's there configuration on .env file that i'm missing so my app use production.yaml?

second, i've installed iRedMail smtp server and secure it with certbot certificate on my server, which port do i use? port 25 or 587?

this is my env file

ENV=production
REDIS_URL="redis://127.0.0.1"
DATABASE_URL="postgres://user:******@localhost:5432/my_app_db"
DATABASE_URL_TEST="postgres://user:******@localhost:5432/my_app_db"
DB_CONNECT_TIMEOUT="500"
DB_IDLE_TIMEOUT="500"
DB_MIN_CONNECTIONS="1"
DB_MAX_CONNECTIONS="1"
SMTP_HOST="mail.server.app"
SMTP_PORT=587
SMTP_USER="[email protected]"
SMTP_PASSWORD="*********"
SMTP_SENDER="My App"

this is part of production.yaml

# Mailer Configuration.
mailer:
  # SMTP mailer configuration.
  smtp:
    # Enable/Disable smtp mailer.
    enable: true
    # SMTP server host. e.x localhost, smtp.gmail.com
    host: {{ get_env(name="SMTP_HOST", default="mail.server.app") }}
    # SMTP server port
    port: {{ get_env(name="SMTP_PORT", default=587) }}
    # Use secure connection (SSL/TLS).
    secure: true
    auth:
      user: {{ get_env(name="SMTP_USER", default="[email protected]") }}
      password: {{ get_env(name="SMTP_PASSWORD", default="*******") }}
    # Override the SMTP hello name (default is the machine's hostname)
    hello_name: {{ get_env(name="SMTP_SENDER", default="localhost") }}

best regards

Not sure where you got APP_ENVIRONMENT from—the expected environment variable is LOCO_ENV.
