In previous posts, we’ve covered our Kubernetes framework for an alternative back-end to Aegir5, as well as the front-end Tasks and Operations and Clusters, Projects, Releases, and Environments. We also discussed the Queue architecture that ties the front- and back-ends together. This time, let’s consider the planned feature parity between Aegir 3 and Aegir 5.
Clusters, Projects, Releases, and Environments In Aegir3, Servers only have a “verify” task. This ensures that the front end can connect to the server over SSH.
Previously in this series, we looked at the Aegir5 front-end interface architecture, as well as the lower level entities, Tasks and Operations that provide building blocks.
As mentioned in the first part of the series, our most recent work on Aegir5 itself has been reworking the queue system. In this post, we explore this topic in more detail.
The Aegir5 queue is implemented using Celery, which is a full-featured Python-based task queue, built atop RabbitMQ.
In our previous post, we looked at the Tasks and Operations which form the building blocks for the user interface in Aegir5. Here we’ll look at the additional entities required to support the Kubernetes-based backend framework.
It is worth noting that Aegir has always had a tension between Developer and SysAdmin use-cases. We’ll cover this in more depth in a later post. For the moment, we’re focused on the Developer use-case.
In our previous post, we talked about our recent client work building a Kubernetes-based system for hosting web applications. We’ve defined a general framework to support our development and production hosting workflows, and recognized this as a solid basis for an alternate backend to plug in to the existing Aegir5 front-end. Today we’ll take a look at the Drupal architecture underlying that front-end.
In Aegir5, the building blocks consist of Task and Operation entities.
Aegir5 development is happening! We (Consensus) have been making steady progress on it over the last few years and are looking to kick off a new burst of focused development. Here’s a summary of progress that has been made so far and how you can contribute.
First off, as you’re probably aware, Aegir5 is a complete re-write of Aegir. We are intending to build on all the great aspects of Aegir, while freeing ourselves from a codebase that is rooted in PHP 4.
