The (Obscure) Quote of the Moment Service

This is a long-lived branch of the quote service for use in the tour application.

This branch is pulled into datawire/tour as the backend/ directory via a git subtree.

All updates to the tour backend should be made against the tour-master branch of datawire/quote and pulled into tour by running:

git subtree pull --prefix backend https://github.com/datawire/quote tour-master --squash

---

Building the application

docker build -t {DOCKER_USERNAME}/{IMAGE_NAME}:{VERSION} .

Ex: docker build -t datawire.io/quote:0.5.0 .

---

Running the application

Run with Docker:

docker run -p 8080:8080 {IMAGE}

Pass environment variables with Docker:

docker run -p 8080:8080 -e ENVIRONMENT_VARIABLE='value' {IMAGE}

Endpoints & making requests

Note: The following curl commands assume that you have deployed this application by following the Ambassador Edge Stack quickstart guide. /backend/ is the prefix for routing requests to this service, and is dropped before the request hits the quote service. If you are running via docker, then you will not need to add /backend/ to any of your requests and can just use the endpoints directly.

---

• /

  GET: Gets a randomly selected quote and a string to represent the name of the quote service.

  Ex: curl -kv https://{IP_ADDR}/backend/

---

• /get-quote/

  GET: Gets a randomly selected quote and a string to represent the name of the quote service.

  Ex: curl -kv https://{IP_ADDR}/backend/get-quote/

---

• /debug/

  GET: Prints headers and information about the request.

  POST: Prints headers and information about the request and sends the body of the request back as well.

  Ex: curl -kv https://{IP_ADDR}/backend/debug/

---

• /debug/*

  GET: Functions the same as the /debug/ path without a POST option.

  Ex: curl -kv https://{IP_ADDR}/backend/debug/{path}

---

• health

  GET: Returns a 200 OK when the service is functioning.

  Ex: curl -kv https://{IP_ADDR}/backend/health

---

• /auth/*

  GET: Alternates between sending a 500 Internal Server Error and 200 OK response each time you make a request to this endpoint.

  Ex: curl -kv https://{IP_ADDR}/backend/auth/*

---

• /sleep/*

  GET: Queries the URL for an ammount of time to sleep for before responding to the request. Defaults to one second when it is unable to parse a sleep parameter.

  Ex: curl -kv https://{IP_ADDR}/backend/sleep/

  Ex: curl -kv https://{IP_ADDR}/backend/sleep/\?sleep=5

  Note: You need to escape the ?sleep on the command line. On a browser you can exclude the \

---

• /files/

  GET: returns a list of files available to be downloaded.

  POST: Uploads a file to the service to be downloaded later. Overwrites existing files if provided with the same name as an existing file. Uses the path as the name for the file.

  Ex: curl -kv https://{IP_ADDR}/backend/files/

  Ex: curl -kv --form "file=@README.md" https://{IP_ADDR}/backend/files/

  Note: The FILE_PATH environment varialbe is used to configure a custom path for storing files if using a persistent volume in Kubernetes. Otherwise it will default to storing files ephemerally inside the container.

  Note: For successful file uploads it expects the file to be passed in a value called file exactly as shown in the example.

---

• /files/*

  GET: returns a file of the provided name if it exists or a 404 if it cannot find the file. The container ships with a file edgy.jepg for testing.

  Ex: curl -kv https://{IP_ADDR}/backend/files/edgy.jpeg
