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" leather_jacket ``` --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://davidsietz.gitbook.io/daas-workshop/module-06/section-iv-starting-the-service.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
