The fs-api provides a REST API for the
FatSecret service. See the architecture
documentation for an overview.
In order to use fs-api one needs to
register to obtain OAuth 1.0
Credentials. These Consumer Key and Consumer Secret have to be provided
to fs-api as environment variables. Assuming a bash like shell:
$ export FATSECRET_CONSUMER_KEY=...
$ export FATSECRET_CONSUMER_SECRET=...After that the application can be started from the top-level application directory as
$ mvnw spring-boot:runAlternativly you can split the tasks of building the (fat) JAR file from executing it:
$ mvnw package
$ java -jar target/fs-api-0.0.1-SNAPSHOT.jarFor tests it is helpful to have a JSON pretty printer like jq
available:
$ curl --silent http://localhost:8080/api/v1/food?q=avocado | jq

}The API can be packaged as a Docker image with
$ mvnw install dockerfile:buildThe resulting image can be run with
$ docker run -d --rm -p 8080:8080 \
-e FATSECRET_CLIENT_ID -e FATSECRET_CLIENT_SECRET \
rstub/fs-apiIf the docker container is run some other way (docker-compose,
kubernetes, ...) the port-forwarding and environment variables have to
be defined in the run-time configuration.
