Combining Progressive Delivery With GitOps And Continuous Delivery

Three phrases keep popping up when talking about modern workflows and development and deployment techniques; CD, GitOps, and progressive delivery.
Three phrases keep popping up when talking about modern workflows and development and deployment techniques. We have continuous delivery to automate the complete lifecycle of applications from a commit to a Git repository, all the way until a release is deployable to production. Then we have GitOps to define the desired states of our environments and let the machines handle the converge the actual into the desired state. Finally, there is a lot of focus on different deployment strategies grouped under progressive delivery. They are all focused on the iterative release of features to make the process safe, prevent downtime, and reduce the blast radius of potential issues. While those three practices and the tooling behind those are focusing on specific areas, the "real" benefits are obtained when they are combined. Nevertheless, many did not yet reach that stage. Each of those practices alone can be daunting and, frankly, scary. Yet, we should go a step further and explore how to combine them together and see the benefits such a solution might provide. Through a hands-on demo, we will combine Argo CD as a tool of choice for applying GitOps, Argo Rollouts for progressive delivery, and Argo Workflows for continuous delivery pipelines that will tie those two together with the rest of the steps needed in the lifecycle of our applications. If we are successful, we might remove humans from all the actions coming after pushing changes to Git repositories.

The emergence of virtualization, containers, and cloud native has resulted in tremendous advances in enabling organizations to develop new services and make them available to end users. In addition, new paradigms such as Continuous Integration (CI) and Continuous Delivery (CD) allow organisations to do this much faster than before, empowering them to go to market ahead of the competition. Despite its many advantages, the CI/CD ecosystem has its challenges. This session will discuss issues ...

Continuous integration and deployment (CI/CD) system are hardly ever ceaseless as the name would suggest; they do aim though to follow changes in code, configurations and versions. They often achieve that by both handling and generating events. For instance, a CD system receives an event that describes a new version of an application, and it runs a workflow in response. When the workflow starts or when it reaches completion, the CD system generates events for the benefit of other processes that ...

Recently, the MariaDB Foundation has been developing a new continuous integration framework for the MariaDB Server. The goal of buildbot.mariadb.org is to ensure that each change is properly tested on all supported platforms and operating systems. Our new CI uses almost exclusively latent workers, more exactly Docker latent workers. In this talk, I will present a main overview of the CI infrastructure, the advantages of using latent workers and talk about the challenges that we encountered along ...

Kubernetes, GitOps, and Infrastructure as Code are as powerful as they are popular and seem like the perfect match. Consequently, using Terraform to maintain Kubernetes clusters and resources is a very common use-case. And it requires careful integration of many moving parts, from Terraform providers and modules, to CI/CD pipelines and triggers. However, despite this being such a popular use-case, teams previously had no alternative than writing everything from scratch. On the software ...

The Kubernetes tooling landscape is littered with template based solutions to deal with all the YAML needed to get things done. Kuberig takes a different approach that developers will love! No need to learn another template language or tool. With Kuberig you define your resources using Kotlin code and deploy them by executing Gradle tasks. Simple.
