Hands-On Microservices with Rust

Compiling and running

To run a microservice created with Rocket, you need to create a Rocket.toml configuration file. This allows you to configure a microservice before starting. Look at the following Rocket.toml contents:

[global]template_dir = "static"address = "127.0.0.1"port = 8003[global.databases.sqlite_database]url = "test.db"
