Deployment

Deployment is super simple in Loco, and this is why this guide is super short. Although most of the time in developemnt you are using cargo when deploying, you use the binary that was compiled, there is no need for cargo or Rust on the target server.

To deploy, build your production binary for your relevant server architecture:

$ cargo build --release

And copy your binary along with your config/ folder to the server. You can then run myapp start on your server.

That's it!

We took special care that all of your work is embbedded in a single binary, so you need nothing on the server other than that.

Review your production config

There are a few configuration sections that are important to review and set accordingly when deploying to production:

  • Logger:
logger:
  level: <your production log level>
  • Server:
server:
  # Port on which the server will listen. the server binding is 0.0.0.0:{PORT}
  port: 3000
  # The UI hostname or IP address that mailers will point to.
  host: http://localhost
  • Database:
database:
  # Database connection URI
  uri: postgres://loco:loco@localhost:5432/loco_app
  • Mailer:
mailer:
  # SMTP mailer configuration.
  smtp:
    # Enable/Disable smtp mailer.
    enable: true
    # SMTP server host. e.x localhost, smtp.gmail.com
    host: localhost
  • Redis:
redis:
  # Redis connection URI
  uri: redis://127.0.0.1/
  • JWT secret:
auth:
  # JWT authentication
  jwt:
    # Secret key for token generation and verification
    secret: ...

Generate

Loco offers a deployment template enabling the creation of a deployment infrastructure.

cargo loco generate deployment
? ❯ Choose your deployment ›
 Docker
 Shuttle
 Nginx

..
 ❯ Choose your deployment · Docker
skipped (exists): "dockerfile"
added: ".dockerignore"

Deployment Options:

  1. Docker:
  • Generates a Dockerfile ready for building and deploying.
  • Creates a .dockerignore file.
  1. Shuttle:
  • Generates a shuttle main function.
  • Adds shuttle-runtime and shuttle-axum as dependencies.
  • Adds a bin entrypoint for the deployment.
  1. Nginx:
  • Generates a nginx configuration file for reverse proxying.

Choose the option that best fits your deployment needs. Happy deploying!
