Section IV - starting the service

We are now ready to start the RESTful service that will act as the data source for our DaaS platform.The web service will provide a JSON document(s) with the number of new orders by product.

There are 2 ways to start the service.

1. Running using cargo run command while developing (local service testing)

NOTE: we provide the argument --bin myapp_reporting because there are now multiple executables and must specify which one to run.

ArchConfWorkshopUser:~/environment/rust-daas (master) $ cargo run --bin myapp_reportinging
   Compiling rust-daas v0.1.0 (/home/ec2-user/environment/rust-daas)
    Finished dev [unoptimized + debuginfo] target(s) in 11.71s
     Running `target/debug/myapp_sourcing`

To stop the service, use ctrl + c.

2. Running using the executable.

ArchConfWorkshopUser:~/environment/rust-daas (master) $ cargo build
   Compiling rust-daas v0.1.0 (/home/ec2-user/environment/rust-daas)
    Finished dev [unoptimized + debuginfo] target(s) in 7.23s

Whenever you use the cargo build command, it places the created executable in the target/debug directory with the same name that was defined in the Cargo.toml manifest.

Since it is an executable, simple run the executable from the command terminal.

ArchConfWorkshopUser:~/environment/rust-daas (master) $ ./target/debug/myapp_reporting 

Checking the web service

Let's make sure the web service is working correctly by running the following script in an available terminal.

Query number of orders for all products

./scripts/curl-reporting.sh

ArchConfWorkshopUser:~/environment $ ./scripts/curl-reporting.sh
all

Query number of orders for the leather jacket product

./scripts/curl-reporting.sh -p "leather jacket"

ArchConfWorkshopUser:~/environment $ ./scripts/curl-reporting.sh -p "leather jacket"
