mulder is the backend side of The Jenkins X Files - the Jenkins X workshop. You can also see Scully, the frontend side.

It's a Go application that provides a (very) basic HTTP API, with 1 main endpoint:

• GET /quote/random which returns a random quote from FBI's most unwanted, in JSON:

  {
      "quote": "I have a theory. Do you want to hear it?"
  }
  

• GET /healthz checks the health of the application, and the connection to Redis. It returns either a 200 or 500 status code.

Dependencies:

• Redis - to store the quotes

Building:

• go build

Running:

Either:

• build the binary with go build, and run it
• or run it directly with go run .

Flags:

• -listen-addr (string): host:port on which to listen. Default: :8080
• -redis-addr (string): redis host:port to connect to. Default: :6379
• -redis-connect-timeout (duration): timeout for connecting to redis. Default: 1m0s

Unit Tests:

• go test -v .

Integration Tests:

• go test -v ./tests -addr HOST:PORT
  • don't forget to replace the HOST:PORT argument with the hostname and port of a running mulder instance you want to test - the integration tests won't start it for you.

It ain't there, and it's on purpose - because the goal of the workshop is to write them, or at least have them automatically generated by Jenkins X.

But you can still find:

• a Docker image on the dockerhub, at thejenkinsxfiles/mulder
  • Pull it with docker pull thejenkinsxfiles/mulder:1.0.0
  • Check the Dockerfile in the dockerfile branch
• an Helm chart at https://the-jenkins-x-files.github.io/charts/
  • Check the chart sources in the helm-chart branch
