We are running Rancher in combination with the in-built load balancer HAProxy. For each of our customers, our application is provided as a single container, many on the same physical server instance. Each of the customers' applications can be accessed via different URLs, so the usage of the HAProxy as the routing component part of the load balancer makes sense.

Linking Docker containers can be done in various ways. In my recent attempt of playing with Docker and our GitLab Review Apps setup, I experimented with different methods to figure out what would work best. These are the different options I played around with:

With the newest release of the Force Login module for Magento 2, you are now able to change the way to define your whitelist rules. For starters, you can choose between the already known regex-based interpreter strategy and the new static-based interpreter. The latter makes it now very easy to whitelist simple URLs without the requirement to know regex syntax. We also moved the configuration tab to "Customer > Customer Configuration" section.

When we made the move to GitLab 1,5 years ago, it was clear to me that we would need some automation to simplify the creation of groups and projects and to sync the LDAP group memberships to the matching GitLab groups. I did a quick search on Packagist for GitLab client libraries and found the m4tthumphrey/php-gitlab-api package.

I wasn't really happy with the current approaches of dealing with different Dockerfiles and docker-compose.yaml files for development and production containers. I don't really see the point of managing multiple configuration files, building a few intermediate containers when the only difference between a development image and a production image is that the code is copied into the image during build. Adding files on every build is also not an ideal solution as you could potentially ship an old version of the application when you miss running a docker build after you made your final changes.

In my recent talk on introducing Disco - the DI container with the damn coolest name(tm) - I talk about why I believe that using XML or any other non-code configuration (YAML, JSON, ...) is not a good idea. This stirred some twitter discussion recently which led to this blog post.

In a recent attempt to automate a few things even more, I was looking for a way to post messages to our Mattermost instance via the Incoming Webhook feature of Mattermost. I did a quick search on Packagist for Mattermost client libraries and as it turns out there a quite a few. I picked the thibaud-dauce/mattermost-php package simply because it was the first match ;)

When providing and consuming webservices both sides do their best to fulfill the WSDL contract. But what if one side can not fulfill the contract? To be concrete, the client sends us SOAP requests but omits the application's namespace. So instead of:

Last week we released Disco version 0.9.0 with a few new features and unfortunately some BC breaks. The BC breaks are all covered in the upgrade guide, but I would like to discuss them in greater detail to give you a better understanding why those changes happened:

Since the first release of our ng2-combobox components for Angular the repository is still lacking a decent documentation on how to use the component if you are not that familiar with Angular. This blog post should give you some insights on how to set up the combobox component in an Angular application. If you haven't yet set up an Angular application yourself it is as simple as typing the following command:
