Persistent storage in Docker containers using Rancher-NFS

·3 mins
Number one challenge when you are using Docker in production environments is storage. On you local development machine it is possible to mount a local directory path into your docker container, but in production environments, this isn’t an option because you don’t know if the path exists and if the docker container is always running on the same node. A solution is NFS, and when using Rancher, Rancher-NFS.

Setup your private GitLab server with Docker (and Rancher)

·3 mins

As a developer, I used GitHub a lot to store my (private) projects. This works great, but I do miss the CI integration as done by GitLab. I could use public services like Travis, but they do charge for private projects.

Because we’re using GitLab and GitLab CI at work I wondered how much work it would be to setup my private GitLab server on my Rancher environment. In this blog post, I will share the results with you.

Password complexity and blacklist in Symfony (optionally with FOSUserBundle)

·3 mins
Password strength is a more and more important subject for (web) applications. I guess we have all read at least one time about user accounts got hijacked because the user used a password like ‘1234567890’ and ‘qwerty’.

And can I do that with my favorite language PHP? Yes I can, with Robo PHP!

Test your Doctrine2 metadata mapping configuration

·2 mins
I use the Doctrine2 Object Relational Mapper as abstraction layer between my model and database. I use PHPUnit to unit test my code, but if the configuration is incorrect the code won’t work like intended and the Doctrine2 ORM will fail with exceptions as result. To ensure the configuration is correct I created a test to validate my configuration.
