infra-problem's Introduction

DevOps Assessment

This project contains three services:

quotes which serves a random quote from quotes/resources/quotes.json
newsfeed which aggregates several RSS feeds together
front-end which calls the two previous services and displays the results.

Prerequisites

Java
Leiningen (can be installed using brew install leiningen)

Running tests

You can run the tests of all apps by using make test

Building

First you need to ensure that the common libraries are installed: run make libs to install them to your local ~/.m2 repository. This will allow you to build the JARs.

To build all the JARs and generate the static tarball, run the make clean all command from this directory. The JARs and tarball will appear in the build/ directory.

Static assets

cd to front-end/public and run ./serve.py (you need Python3 installed). This will serve the assets on port 8000.

Running

All the apps take environment variables to configure them and expose the URL /ping which will just return a 200 response that you can use with e.g. a load balancer to check if the app is running.

Front-end app

java -jar front-end.jar

Environment variables:

APP_PORT: The port on which to run the app
STATIC_URL: The URL on which to find the static assets
QUOTE_SERVICE_URL: The URL on which to find the quote service
NEWSFEED_SERVICE_URL: The URL on which to find the newsfeed service
NEWSFEED_SERVICE_TOKEN: The authentication token that allows the app to talk to the newsfeed service. This should be treated as an application secret. The value should be: T1&eWbYXNWG1w1^YGKDPxAWJ@^et^&kX

Quote service

java -jar quotes.jar

Environment variables

APP_PORT: The port on which to run the app

Newsfeed service

java -jar newsfeed.jar

Environment variables

APP_PORT: The port on which to run the app

infra-problem's Issues

running "make test" fails testing timestamps

This is related to the hard coded timezone in the strings.

Dependencies not met / artifact not found on running "make test"

Hi,

while executing make test, it occurred to me that some dependency cannot get resolved properly or artifacts are missing upstream:

Log of a second run of make test:

$ make test
cd common-utils && lein midje
WARNING: any? already refers to: #'clojure.core/any? in namespace: leiningen.midje, being replaced by: #'leiningen.midje/any?
nil
All checks (2) succeeded.
cd front-end && lein midje
WARNING: any? already refers to: #'clojure.core/any? in namespace: leiningen.midje, being replaced by: #'leiningen.midje/any?
Could not find artifact com.thoughtworks:common-utils:jar:0.1.0-SNAPSHOT in clojars (https://repo.clojars.org/)
This could be due to a typo in :dependencies, file system permissions, or network issues.
If you are behind a proxy, try setting the 'http_proxy' environment variable.
make: *** [front-end.test] Error 1

Error-message:

Could not find artifact com.thoughtworks:common-utils:jar:0.1.0-SNAPSHOT in clojars (https://repo.clojars.org/)

It'd be great if you could update or fix the dependencies.
