Securing Jenkins with oAuth

Jenkins is pretty easy to secure with the help of some useful plugins.

The first that I suggest using is an oAuth provider. Our repositories are hosted on Bitbucket so I'm using their oAuth, but there is also a Github oAuth plugin. The instructions to set up the plugin are very clear (see the plugin page).

When you're configuring your Jenkins to use the oAuth security remember to leave the Authorization setting to "logged in users can do anything" for now. We'll change this later, but we don't want to get locked out of Jenkins when we apply the security settings.

Now install the plugin Role Based Authentication Strategy (see the plugin page).

Add a new group called "Anonymous" and uncheck everything.

When a user logs into the oAuth they'll be given a message by Jenkins saying that they don't have any permissions. This means that not everybody with a Bitbucket account can access your site so thats a good thing.

You just need to add them to the roles plugin settings. Click Manage Jenkins then Manage and Assign Roles. Click on assign roles and add the user. Then tick the boxes of the roles you want to assign them.

Separating business logic from persistence layer in Laravel

There are several reasons to separate business logic from your persistence layer. Perhaps the biggest advantage is that the parts of your application which are unique are not coupled to how data are persisted. This makes the code easier to port and maintain. I'm going to use Doctrine to replace the Eloquent ORM in Laravel. A thorough comparison of the patterns is available here . By using Doctrine I am also hoping to mitigate the risk of a major version upgrade on the underlying framework. It can be expected for the ORM to change between major versions of a framework and upgrading to a new release can be quite costly. Another advantage to this approach is to limit the access that objects have to the database. Unless a developer is aware of the business rules in place on an Eloquent model there is a chance they will mistakenly ignore them by calling the ActiveRecord save method directly. I'm not implementing the repository pattern in all its ...

"Word of the Day" PHP script (with word list)

I was looking around for a way to generate a word of the day on the web and didn't find anything. So I coded a quick and dirty script to do it. Just in case anybody does a Google search and manages to find my blog: here is my Word of the Day PHP script : Copy this code snippet into a wordoftheday.php file: $file = fopen("interesting_words.txt","r"); $raw_string = fread($file,filesize("interesting_words.txt")); fclose($file); $words_array = explode("|",$raw_string); echo $words_array[array_rand($words_array)]; Of course the real issue I had was finding a list of interesting words in the right format. Here is the list of interesting words that I used: Copy this into a file called interesting_words.txt : ubiquitous : being or seeming to be everywhere at the same time; omnipresent| ecdysiast : a striptease artist| eleemosynary : of, relating to, or dependent on charity| gregious : c...

Solving Doctrine - A new entity was found through the relationship

There are so many different problems that people have with the Doctrine error message: exception 'Doctrine\ORM\ORMInvalidArgumentException' with message 'A new entity was found through the relationship 'App\Lib\Domain\Datalayer\UnicodeLookups#lookupStatus' that was not configured to cascade persist operations for entity: Searching through the various online sources was a bit of a nightmare. The best documentation I found was at http://www.krueckeberg.org/ where there were a number of clearly explained examples of various associations. More useful information about association ownership was in the Doctrine manual , but I found a more succinct explanation in the answer to this question on StackOverflow . Now I understood better about associations and ownership and was able to identify exactly what sort I was using and the syntax that was required. I was implementing a uni-directional many to one relationship, which is supposedly one of the most simpl...
