Anyone working with Kubernetes knows how hard it is to put out a Kubernetes release. But actually, how are releases cut? This talk is for cloud-native practitioners who care about the environmental impact of their work. Focusing on insight into daily life, the tools, and the methodologies, the release engineers have a strong identity of the ecological consideration at every step.

We'll explore key aspects such as the automation tools that streamline the release process, the challenges of ensuring efficient resource usage, and the design principles that promote sustainability. Through practical demonstrations, we'll showcase best practices like optimizing CI/CD pipelines and leveraging containerization for minimal resource consumption. Participants will be equipped with actionable knowledge to enhance the sustainability of their Kubernetes releases. The key takeaway would be how the existing tools could be adapted and shared by more of the project, like image promoters.
